Disclosure of Invention

The present invention is directed to solving at least one of the problems of the prior art. Therefore, an object of the present invention is to provide a mobile air conditioner control method, which can solve the problems of instability and excessive current value of a mobile air conditioner in a high temperature environment in the prior art without increasing the material cost of the whole mobile air conditioner and without affecting the user experience.

Another objective of the present invention is to provide a mobile air conditioner control device using the above mobile air conditioner control method.

Still another object of the present invention is to provide a mobile air conditioner using the above control method of the mobile air conditioner.

The mobile air conditioner control method according to the embodiment of the first aspect of the invention comprises the following steps:

when the mobile air conditioner operates under a high-temperature working condition, acquiring the ambient temperature in the action space of the mobile air conditioner;

adjusting the indoor air volume of the mobile air conditioner according to the difference value between the acquired environment temperature and the target temperature threshold; and the target temperature threshold is the temperature limit value of the environment in the action space when the mobile air conditioner meets the condition that the current value does not exceed the standard and the mobile air conditioner stably runs.

According to the control method of the mobile air conditioner, when the mobile air conditioner operates under a high-temperature working condition, the ambient temperature in the space where the mobile air conditioner acts is obtained, and then the indoor air volume of the mobile air conditioner can be adjusted according to the difference value between the obtained ambient temperature and the target temperature threshold value, wherein the target temperature threshold value can be understood as the temperature limit value of the environment in the space where the mobile air conditioner acts when the current value does not exceed the standard and the mobile air conditioner stably operates. Therefore, the invention sets the target temperature threshold value, compares the environmental temperature in the mobile air-conditioning action space with the target temperature threshold value, and adjusts the indoor air volume of the mobile air-conditioning based on the difference value between the two, for example, when the difference value between the acquired environmental temperature and the target temperature threshold value meets a certain condition, if the difference value is larger than or equal to the first threshold value and smaller than the second threshold value, namely the environmental temperature in the mobile air-conditioning action space is higher than a certain value of the target temperature threshold value, the indoor air volume (namely the evaporation side) can be reduced, the heat load on the outdoor side (namely the condensation side) can be indirectly reduced by reducing the indoor air volume, thereby the power of the compressor can be reduced, the current value of the whole machine can be reduced, because the control logic of the embodiment of the invention can be written into the control chip of the mobile air-conditioning, the temperature sensor is matched with the existing temperature sensor of the mobile air conditioner for use, so that the problems of unstable operation and overhigh current value of the mobile air conditioner in a high-temperature environment are solved under the conditions that the overall material cost is not increased and large system change (namely, user experience is not influenced) is not carried out.

In addition, there are various methods for adjusting the indoor air volume of the mobile air conditioner, for example, the indoor air volume can be adjusted by changing the rotation speed of the indoor motor. According to some embodiments of the present invention, the adjusting the indoor air volume of the mobile air conditioner according to the difference between the obtained ambient temperature and the target temperature threshold includes:

determining a target rotating speed of an indoor motor of the mobile air conditioner according to the difference value between the acquired environment temperature and a target temperature threshold value;

and controlling the indoor side motor according to the target rotating speed so as to adjust the indoor side air quantity of the mobile air conditioner.

In order to reduce the indoor air volume (namely, the evaporation side) and further reduce the indoor heat exchange, indirectly reduce the heat load of the outdoor side (namely, the condensation side), further reduce the power of the compressor and reduce the current value of the whole machine, the indoor air volume can be reduced by reducing the rotating speed of the indoor motor. According to some embodiments of the present invention, the determining the target rotation speed of the motor inside the mobile air conditioner room according to the obtained difference between the ambient temperature and the target temperature threshold includes:

detecting whether the difference value between the acquired environment temperature and a target temperature threshold value is greater than or equal to a first threshold value and smaller than a second threshold value; wherein the first threshold is smaller than the second threshold, and the first threshold and the second threshold are both positive numbers;

if the difference value between the acquired environment temperature and the target temperature threshold is greater than or equal to the first threshold and smaller than the second threshold, and the duration is greater than the target time, determining a first rotating speed as a target rotating speed of the indoor motor; and the first rotating speed is less than the initial rotating speed of the indoor motor when the mobile air conditioner is started and operated under the high-temperature working condition.

It should be noted that if the operation condition of the mobile air conditioner is worse, for example, the mobile air conditioner is operated in a higher environment, the indoor motor can be controlled to operate at a lower rotation speed in order to further reduce the motor power and the indoor evaporation capacity and further reduce the compressor power. According to some embodiments of the present invention, when the difference between the acquired ambient temperature and the target temperature threshold is greater than or equal to the second threshold and the duration is greater than the target time, a second rotation speed is controlled as a target value of the indoor-side motor, where the second rotation speed is less than the first rotation speed.

Since the indoor temperature gradually changes along with the operation of the mobile air conditioner, the ambient temperature acquired more currently is required to adjust the rotation speed of the indoor motor. According to some embodiments of the present invention, when the difference between the acquired ambient temperature and the target temperature threshold is smaller than a third threshold and the duration is longer than the target time, controlling a third rotation speed as the target value of the indoor motor, wherein the third threshold is a negative number; the third rotating speed is the initial rotating speed of the indoor side motor when the mobile air conditioner is started to operate under the high-temperature working condition;

and when the difference value between the acquired environment temperature and the target temperature threshold is greater than or equal to the third threshold and smaller than the second threshold and the duration is greater than the target time, controlling the first rotating speed as the target value of the indoor motor. Therefore, under the condition of solving the problems of unstable operation and overhigh current value of the mobile air conditioner in a high-temperature environment, the indoor temperature can be reduced as soon as possible, so that the refrigeration requirement of a user is not influenced.

In addition, there are various ways to adjust the indoor air volume of the mobile air conditioner, for example, the indoor air volume can be adjusted by changing the angle of the indoor air outlet. According to some embodiments of the present invention, the adjusting the indoor air volume of the mobile air conditioner according to the difference between the obtained ambient temperature and the target temperature threshold includes:

determining a target angle of an air outlet at the indoor side of the mobile air conditioner according to the difference value between the acquired environment temperature and a target temperature threshold value;

and controlling the angle of the indoor side air outlet according to the target angle so as to adjust the indoor side air quantity of the mobile air conditioner.

In order to reduce the air quantity of the indoor side (namely, the evaporation side), thereby reducing the heat exchange of the indoor side, indirectly reducing the heat load of the outdoor side (namely, the condensation side), thereby reducing the power of the compressor, reducing the current value of the whole machine, and reducing the air quantity of the indoor side by reducing the angle of the air outlet of the indoor side. According to some embodiments of the present invention, the determining a target angle of the indoor side air outlet of the mobile air conditioner according to the obtained difference between the ambient temperature and the target temperature threshold includes:

when the difference value between the acquired environment temperature and the target temperature threshold is greater than or equal to a first threshold and smaller than a second threshold and the duration time is longer than the target time, determining a first angle as the target angle of the indoor side air outlet; the first angle is smaller than the initial angle of the indoor air outlet when the mobile air conditioner is started and operated under the high-temperature working condition; the first threshold is smaller than the second threshold, and the first threshold and the second threshold are both positive numbers.

It should be noted that if the operation condition of the mobile air conditioner is worse, for example, the mobile air conditioner is operated in a higher environment, the indoor air outlet can be controlled to operate at a smaller angle in order to further reduce the power of the motor and the indoor evaporation capacity and further reduce the power of the compressor. In some embodiments of the present invention, when the difference between the acquired ambient temperature and the target temperature threshold is greater than or equal to the second threshold and the duration is greater than the target time, a second angle is used as a target value of the indoor-side air outlet to control, where the second angle is smaller than the first angle.

The mobile air conditioner control device according to the embodiment of the second aspect of the present invention includes:

the environment temperature acquisition module is used for acquiring the environment temperature in the action space of the mobile air conditioner when the mobile air conditioner operates under a high-temperature working condition;

the control module is used for adjusting the indoor air volume of the mobile air conditioner according to the difference value between the acquired environment temperature and the target temperature threshold value; and the target temperature threshold is the temperature limit value of the environment in the action space when the mobile air conditioner meets the condition that the current value does not exceed the standard and the mobile air conditioner stably runs.

According to the control device of the mobile air conditioner, when the mobile air conditioner runs under a high-temperature working condition, the ambient temperature in the action space of the mobile air conditioner can be obtained through the ambient temperature obtaining module, the control module adjusts the indoor air volume of the mobile air conditioner according to the difference value between the obtained ambient temperature and the target temperature threshold, and the target temperature threshold can be understood as the temperature limit value of the environment in the action space when the mobile air conditioner does not exceed the standard and stably runs. Therefore, the invention sets the target temperature threshold value, compares the environmental temperature in the mobile air-conditioning action space with the target temperature threshold value, and adjusts the indoor air volume of the mobile air-conditioning based on the difference value between the two, for example, when the difference value between the acquired environmental temperature and the target temperature threshold value meets a certain condition, if the difference value is larger than or equal to the first threshold value and smaller than the second threshold value, namely the environmental temperature in the mobile air-conditioning action space is higher than a certain value of the target temperature threshold value, the indoor air volume (namely the evaporation side) can be reduced, the heat load on the outdoor side (namely the condensation side) can be indirectly reduced by reducing the indoor air volume, thereby the power of the compressor can be reduced, the current value of the whole machine can be reduced, because the control logic of the embodiment of the invention can be written into the control chip of the mobile air-conditioning, the temperature sensor is matched with the existing temperature sensor of the mobile air conditioner for use, so that the problems of unstable operation and overhigh current value of the mobile air conditioner in a high-temperature environment are solved under the conditions that the overall material cost is not increased and large system change (namely, user experience is not influenced) is not carried out.

A mobile air conditioner control method according to an embodiment of a first aspect of the present invention is described below with reference to fig. 1 to 8.

It should be noted that the mobile air conditioner according to the embodiment of the present invention may be an integral air conditioner. For example, as shown in fig. 1 and fig. 2, the mobile air conditioner of the embodiment of the present invention is distinguished from a split air conditioner, and is characterized in that the evaporator 4, the condenser 7, the compressor 9, the throttle assembly 6, the fan duct 1, the fan duct 2, and other structural members are all in the same box structure, a user can use the mobile air conditioner by connecting an exhaust duct, and the bottom of the mobile air conditioner is provided with 4 casters, which is convenient for the user to move. In some embodiments of the present invention, the indoor side of the mobile air conditioner is generally referred to as the evaporator 4 and the corresponding fan duct 1, the indoor side motor 8, and the outdoor side is generally referred to as the condenser 7 and the corresponding fan duct 2 and the outdoor side motor 3.

In order to solve the problems of instability and overhigh current value of a mobile air conditioner in operation in a high-temperature environment, the embodiment of the invention provides a mobile air conditioner control method, a control device, a mobile air conditioner and a storage medium. Specifically, a mobile air conditioner control method, a control device, a mobile air conditioner, and a storage medium according to embodiments of the present invention are described below with reference to the accompanying drawings.

Fig. 3 is a flowchart of a mobile air conditioner control method according to an embodiment of the present invention. It should be noted that the mobile air conditioner control method according to the embodiment of the present invention can be applied to the mobile air conditioner control device according to the embodiment of the present invention, wherein the control device can be configured on the mobile air conditioner according to the embodiment of the present invention.

As shown in fig. 3, the mobile air conditioner control method may include:

step 301, when the mobile air conditioner operates under a high-temperature working condition, obtaining the ambient temperature in the action space of the mobile air conditioner.

For example, as shown in fig. 1, the indoor side of the mobile air conditioner according to the embodiment of the present invention may have a temperature sensor 5, and the temperature sensor may collect an ambient temperature in a space used by the mobile air conditioner and send the collected ambient temperature to the control device of the mobile air conditioner, so that the control device of the mobile air conditioner may obtain the ambient temperature in the space acted by the mobile air conditioner.

It should be noted that the application scenario of the mobile air conditioner in the embodiment of the present invention is a high-temperature environment. Therefore, in order to enable the mobile air conditioner to stably operate in a high-temperature environment and reduce the overall current value, whether the mobile air conditioner operates and is used under a high-temperature working condition can be monitored firstly, if the mobile air conditioner operates under the high-temperature working condition, the ambient temperature collected by the temperature sensor at the indoor side of the mobile air conditioner can be acquired, and therefore the air volume at the indoor side (namely the evaporation side) can be controlled based on the ambient temperature subsequently.

In some embodiments of the present invention, whether the mobile air conditioner is operated and used under a high temperature condition may be monitored by the following methods: when the mobile air conditioner is started, the ambient temperature is collected through the temperature sensor at the indoor side of the mobile air conditioner, and whether the mobile air conditioner operates and is used under a high-temperature working condition is judged based on the currently collected ambient temperature. It can be understood that, if the mobile air conditioner is operated under the high-temperature working condition, the step 301 is executed, and meanwhile, the motor at the indoor side of the mobile air conditioner can be controlled to operate at the set high rotation speed. That is, when the mobile air conditioner is operated at the start of power-on, the indoor motor may be controlled to operate at the highest rotation speed.

And step 302, adjusting the indoor air volume of the mobile air conditioner according to the difference value between the acquired environment temperature and the target temperature threshold value.

In some embodiments of the present invention, the target temperature threshold may be a temperature limit of the environment in the space when the mobile air conditioner is operated stably and the current value is not exceeded. For example, the target temperature threshold T0 is set on a case-by-case basis, and as an example, the target temperature threshold T0 may be set at 35 ℃ to 38 ℃.

In this step, the difference between the obtained ambient temperature and the target temperature threshold may be calculated, and then the indoor air volume of the mobile air conditioner may be adjusted according to the difference between the obtained ambient temperature and the target temperature threshold. For example, if the difference between the acquired ambient temperature and the target temperature threshold satisfies a certain condition, and if the difference is greater than or equal to the first threshold and less than the second threshold, that is, the ambient temperature in the working space of the mobile air conditioner is higher than a certain value of the target temperature threshold, the indoor side (i.e., evaporation side) air volume can be reduced, the indoor side (i.e., evaporation side) air volume is reduced, so that the indoor side heat exchange is reduced, the outdoor side (i.e., condensation side) heat load is indirectly reduced, so that the power of the compressor is reduced, and the overall machine current value is reduced.

In addition, there are various ways to adjust the indoor air volume of the mobile air conditioner, for example, the indoor air volume can be adjusted by changing the rotation speed of the indoor motor, or the indoor air volume can be adjusted by changing the angle of the indoor air outlet. In some embodiments of the present invention, after the mobile air conditioner operates under a high temperature condition and the ambient temperature in the action space of the mobile air conditioner is obtained, the target air volume at the indoor side may be determined according to the difference between the obtained ambient temperature and the target temperature threshold, and then the indoor side motor or the indoor side air outlet may be correspondingly controlled according to the target air volume at the indoor side, so that the indoor side air volume reaches the target air volume. Specific implementation manners can be seen in the detailed description of the subsequent embodiments.

According to the control method of the mobile air conditioner, when the mobile air conditioner operates under a high-temperature working condition, the ambient temperature in the space where the mobile air conditioner acts is obtained, and then the indoor air volume of the mobile air conditioner can be adjusted according to the difference value between the obtained ambient temperature and the target temperature threshold value, wherein the target temperature threshold value can be understood as the temperature limit value of the environment in the space where the mobile air conditioner acts when the current value does not exceed the standard and the mobile air conditioner stably operates. Therefore, the invention sets the target temperature threshold value, compares the environmental temperature in the mobile air-conditioning action space with the target temperature threshold value, and adjusts the indoor air volume of the mobile air-conditioning based on the difference value between the two, for example, when the difference value between the acquired environmental temperature and the target temperature threshold value meets a certain condition, if the difference value is larger than or equal to the first threshold value and smaller than the second threshold value, namely the environmental temperature in the mobile air-conditioning action space is higher than a certain value of the target temperature threshold value, the indoor air volume (namely the evaporation side) can be reduced, the heat load on the outdoor side (namely the condensation side) can be indirectly reduced by reducing the indoor air volume, thereby the power of the compressor can be reduced, the current value of the whole machine can be reduced, because the control logic of the embodiment of the invention can be written into the control chip of the mobile air-conditioning, the temperature sensor is matched with the existing temperature sensor of the mobile air conditioner for use, so that the problems of unstable operation and overhigh current value of the mobile air conditioner in a high-temperature environment are solved under the conditions that the overall material cost is not increased and large system change (namely, user experience is not influenced) is not carried out.

It should be noted that, in some embodiments of the present invention, the indoor air volume can be adjusted by changing the rotation speed of the indoor motor. As an example of one possible implementation, as shown in fig. 4, the mobile air conditioner control method may include:

step 401, when the mobile air conditioner operates under a high-temperature working condition, acquiring the ambient temperature in the action space of the mobile air conditioner.

It should be noted that, for the implementation of step 401, reference may be made to the description of step 301, and details are not described herein again.

And 402, determining a target rotating speed of the motor at the indoor side of the mobile air conditioner according to the difference value between the acquired environment temperature and the target temperature threshold value.

Optionally, the difference between the acquired ambient temperature and the target temperature threshold is compared with the threshold, and if the difference meets a trigger condition for adjusting the indoor air volume, the target rotation speed of the indoor motor needs to be determined based on the difference, so that the indoor motor is controlled based on the target rotation speed, and the adjustment of the indoor air volume is realized.

It is noted that the key to the above triggering condition is to select a reasonable triggering temperature value. In some embodiments of the present invention, the specific implementation process of determining the target rotation speed of the motor at the indoor side of the mobile air conditioner according to the obtained difference between the ambient temperature and the target temperature threshold may be as follows: detecting whether the difference value between the acquired environment temperature and a target temperature threshold value is greater than or equal to a first threshold value and smaller than a second threshold value; the first threshold value is smaller than the second threshold value, and the first threshold value and the second threshold value are positive numbers; if the difference value between the acquired environment temperature and the target temperature threshold is greater than or equal to a first threshold and smaller than a second threshold, and the duration time is longer than the target time, determining the first rotating speed as the target rotating speed of the indoor motor; the first rotating speed is smaller than the initial rotating speed of the indoor motor when the mobile air conditioner is started under the high-temperature working condition.

The first threshold and the second threshold may be understood as the trigger temperature value. The first threshold value and the second threshold value may be set according to specific situations. As an example, the first threshold may be 1, and the second threshold may be 5. For example, after obtaining the ambient temperature in the space where the mobile air conditioner operates, it may be detected whether a difference Δ T between the obtained ambient temperature T and the target temperature threshold T0 is greater than or equal to a first threshold "1" and less than a second threshold "5", and if the difference Δ T is greater than or equal to the first threshold and less than the second threshold, i.e., T0+1 ≦ T < T0+5, and the duration is greater than the target time (e.g., 1 minute), the first rotation speed may be determined as the target rotation speed of the indoor motor, where the first rotation speed is less than the initial rotation speed of the indoor motor when the mobile air conditioner operates at the high-temperature operating condition. As an example, assuming that the indoor-side motor has a third gear rotation speed, i.e., a high gear rotation speed, a middle gear rotation speed, and a low gear rotation speed, the initial rotation speed may be the high gear rotation speed, and the first rotation speed may be the middle gear rotation speed.

That is, when it is detected that the difference Δ T between the ambient temperature T and the target temperature threshold T0 is greater than or equal to the first threshold and less than the second threshold, and the scene duration is greater than the target time (e.g., 1 minute), the middle rotation speed may be set as the target rotation speed of the indoor motor.

And step 403, controlling the indoor motor according to the target rotating speed to adjust the indoor air volume of the mobile air conditioner.

That is, the target rotational speed can be controlled as the target value of the indoor motor, and the indoor air volume can be adjusted. The target rotating speed is the first rotating speed of the indoor motor, and the first rotating speed is smaller than the initial rotating speed of the indoor motor when the mobile air conditioner is started under a high-temperature working condition, so that when the indoor motor is controlled to operate at the first rotating speed, the indoor air volume (namely, the evaporation side) can be reduced, the indoor heat exchange is reduced, the heat load of the outdoor side (namely, the condensation side) is indirectly reduced, the power of the compressor is reduced, and the current value of the whole machine is reduced.

It should be noted that if the operation condition of the mobile air conditioner is worse, for example, the mobile air conditioner is operated in a higher environment, the indoor motor can be controlled to operate at a lower rotation speed in order to further reduce the motor power and the indoor evaporation capacity and further reduce the compressor power. As an example of one possible implementation, when the difference between the acquired ambient temperature and the target temperature threshold is greater than or equal to a second threshold and the duration is greater than the target time, the second rotation speed is controlled as the target value of the indoor-side motor, where the second rotation speed is less than the first rotation speed.

For example, assuming that the second threshold is 5, the first speed is the middle gear speed of the indoor motor, and the second speed is the low gear speed of the indoor motor, when the difference Δ T between the ambient temperature T and the target temperature threshold T0 is greater than or equal to the second threshold, i.e., T ≧ T0+5, and the scenario duration is greater than the target time (e.g., 1 minute), the low gear speed can be controlled as the target value of the indoor motor. Therefore, when the operation condition of the mobile air conditioner is worse, the indoor motor can be controlled to operate at a low-gear rotating speed, so that the power of the motor and the indoor evaporation capacity can be further reduced, the power of the compressor is further reduced, and the current value of the whole machine is reduced.

It can be understood that if mobile air conditioner operates under more abominable operating mode, at the in-process of control room inside motor with low-grade rotational speed operation, ambient temperature in the effect space can reduce gradually, because single tuber pipe mobile air conditioner condenser return air temperature is the same with indoor side temperature, so the condensation load can reduce gradually, satisfy T0+1 and be less than or equal to T < T0+5 when ambient temperature, and this sight duration is greater than 1 minute, steerable indoor side motor operates with middle-grade rotational speed, therefore, under the condition of solving the unstable and too high electric current value problem of operation under the mobile air conditioner high temperature environment, also can reduce indoor temperature as early as possible, in order to avoid influencing user's refrigeration demand.

In some embodiments of the present invention, when the difference between the acquired ambient temperature and the target temperature threshold is smaller than a third threshold and the duration is longer than the target time, controlling the third rotation speed as the target value of the indoor motor, where the third threshold is a negative number; the third rotating speed is the initial rotating speed of the indoor motor when the mobile air conditioner is started under the high-temperature working condition.

That is, since the indoor temperature gradually changes as the mobile air conditioner is operated, the more currently acquired ambient temperature is required to adjust the rotation speed of the indoor side motor. As an example, the third threshold may be-1, the third speed may be a high-gear speed, and when the difference Δ T between the acquired ambient temperature T and the target temperature threshold T0 is less than-1, i.e., T < T0-1, and the duration of the scenario is greater than 1 minute, the indoor motor may be controlled to operate at the high-gear speed. Therefore, under the condition of solving the problems of unstable operation and overhigh current value of the mobile air conditioner in a high-temperature environment, the indoor temperature can be reduced as soon as possible, so that the refrigeration requirement of a user is not influenced.

In some embodiments of the present invention, when the difference between the acquired ambient temperature and the target temperature threshold is greater than or equal to a third threshold and less than a second threshold, and the duration is greater than the target time, the first rotation speed is controlled as the target value of the indoor-side motor. That is, since the indoor temperature gradually changes as the mobile air conditioner is operated, the more currently acquired ambient temperature is required to adjust the rotation speed of the indoor side motor. As an example, the third threshold may be-1, the second threshold may be 5, the first rotation speed is a middle rotation speed, and when the difference Δ T between the acquired ambient temperature T and the target temperature threshold T0 is greater than or equal to the third threshold and less than the second threshold, i.e., T0-1 ≦ T < T0+5, and the duration is greater than the target time, the control room inner motor is operated at the middle rotation speed. Therefore, under the condition of solving the problems of unstable operation and overhigh current value of the mobile air conditioner in a high-temperature environment, the indoor temperature can be reduced as soon as possible, so that the refrigeration requirement of a user is not influenced.

In order to make the control flow of the embodiment of the present invention more clear to those skilled in the art, the following description will be made in detail with reference to fig. 5.

For example, as shown in fig. 5, when the mobile air conditioner is powered on, the indoor motor may be set to operate at a set high-gear rotation speed, and during the operation of the mobile air conditioner, it may be obtained whether the ambient temperature T in the space where the mobile air conditioner operates, and a difference Δ T between the ambient temperature T and a target temperature threshold T0 is greater than or equal to 1, and if not, that is, T is less than T0+1, and the duration of the scenario is greater than 1 minute, the indoor motor is controlled to continue to operate at the set high-gear rotation speed. If the difference delta T between the environment temperature T and the target temperature threshold T0 is greater than or equal to 1, namely T is greater than or equal to T0+1, whether the difference delta T between the environment temperature T and the target temperature threshold T0 is greater than or equal to 5 is further detected, if yes, namely T is greater than or equal to T0+5, and the duration of the situation is greater than 1 minute, the indoor motor is controlled to run at a low-gear rotating speed. And if the difference delta T between the ambient temperature T and the target temperature threshold T0 is greater than or equal to 1 and less than 5, namely T0+1 is greater than or equal to T < T0+5, and the scene duration is greater than 1 minute, controlling the indoor motor to operate at a middle-gear rotating speed. In the process of controlling the indoor motor to operate at a target value, the ambient temperature T in the action space can be continuously obtained, if the difference value delta T between the ambient temperature T and the target temperature threshold value T0 is smaller than-1, namely T is smaller than T0-1, and the scene duration is longer than 1 minute, the indoor motor can be controlled to operate at a high-grade rotating speed; and if the difference delta T between the ambient temperature T and the target temperature threshold T0 is greater than or equal to minus 1 and less than 5, namely T0-1 is greater than or equal to T < T0+5, and the scene duration is greater than 1 minute, operating the indoor motor at a middle-gear rotating speed.

Therefore, the invention reduces the current through a simple and easy control mode, ensures that the current value does not exceed the safe current value of the power line under the condition of not increasing the cost, and avoids the compressor from achieving overload shutdown protection, so that the whole machine can stably and continuously operate under the high-temperature working condition.

According to the mobile air conditioner control method provided by the embodiment of the invention, by setting the target temperature threshold value and comparing the environmental temperature in the action space of the mobile air conditioner with the target temperature threshold value, and then the rotating speed of the indoor motor of the mobile air conditioner is adjusted based on the difference value of the indoor motor and the outdoor motor, so as to adjust the indoor air volume, for example, the difference value between the acquired environmental temperature and the target temperature threshold value meets a certain condition, if the difference value is greater than or equal to a first threshold value and less than a second threshold value, that is, when the ambient temperature in the working space of the mobile air conditioner is higher than a certain value of the target temperature threshold, the indoor side (i.e., the evaporation side) air volume can be reduced, and by reducing the indoor side (i.e., the evaporation side) air volume, therefore, the heat exchange of the indoor side is reduced, the heat load of the outdoor side (namely the condensation side) is indirectly reduced, the power of the compressor is reduced, and the current value of the whole machine is reduced. That is, under the high-temperature working condition operation of the mobile air conditioner, the purpose of reducing the current value of the whole machine for the first time is achieved by reducing the rotating speed of the indoor motor; moreover, the chain reaction played by reducing the rotating speed of the indoor motor is as follows: the air quantity at the inner side (evaporation side) of the room is reduced, the heat exchange at the inner side of the room is reduced, and the heat load at the outer side (condensation side) of the room is indirectly reduced, so that the power of the compressor is reduced, and the purpose of reducing the current value of the whole machine for the second time is achieved.

It should be noted that, in some embodiments of the present invention, the indoor air volume can be adjusted by changing the angle of the indoor air outlet. As an example of one possible implementation, as shown in fig. 6, the mobile air conditioner control method may include:

step 601, when the mobile air conditioner operates under a high-temperature working condition, acquiring the ambient temperature in the action space of the mobile air conditioner.

It should be noted that, the implementation manner of step 601 may refer to the description of step 301, and is not described herein again.

Step 602, determining a target angle of an air outlet at the indoor side of the mobile air conditioner according to the difference between the acquired environment temperature and the target temperature threshold.

Optionally, the difference between the acquired ambient temperature and the target temperature threshold is compared with the threshold, and if the difference meets a trigger condition for adjusting the indoor air volume, a target angle of the indoor air outlet needs to be determined based on the difference, so that the page-swinging position of the indoor air outlet is controlled based on the target angle, and the adjustment of the indoor air volume is realized.

It is noted that the key to the above triggering condition is to select a reasonable triggering temperature value. In some embodiments of the present invention, the specific implementation process of determining the target angle of the indoor side air outlet of the mobile air conditioner according to the difference between the obtained ambient temperature and the target temperature threshold may be as follows: when the difference value between the acquired environment temperature and the target temperature threshold is greater than or equal to a first threshold and smaller than a second threshold and the duration time is longer than the target time, determining the first angle as the target angle of the indoor air outlet; the first angle is smaller than the initial angle of the indoor air outlet when the mobile air conditioner is started under the high-temperature working condition; the first threshold is less than the second threshold, and the first threshold and the second threshold are both positive numbers.

The first threshold and the second threshold may be understood as the trigger temperature value. The first threshold value and the second threshold value may be set according to specific situations. As an example, the first threshold may be 1, and the second threshold may be 5. For example, after obtaining the ambient temperature in the space where the mobile air conditioner operates, it may be detected whether a difference Δ T between the obtained ambient temperature T and the target temperature threshold T0 is greater than or equal to a first threshold "1" and less than a second threshold "5", and if the difference Δ T is greater than or equal to the first threshold and less than the second threshold, that is, T0+1 is greater than or equal to T < T0+5, and the duration is greater than the target time (e.g., 1 minute), the first angle may be determined as the target angle of the indoor side air outlet, and the first angle is less than the initial angle of the indoor side air outlet when the mobile air conditioner operates under the high temperature condition.

Step 603, controlling the angle of the indoor side air outlet according to the target angle to adjust the indoor side air volume of the mobile air conditioner.

That is, the target angle can be controlled to be the target value of the indoor air outlet, so that the indoor air volume can be adjusted. The target rotating speed is the first angle of the indoor side air outlet, and the first angle is smaller than the initial angle of the indoor side air outlet when the mobile air conditioner is started under the high-temperature working condition, so that when the angle of the indoor side air outlet is reduced to the first angle, the air quantity of the indoor side (namely, the evaporation side) can be reduced, the heat exchange of the indoor side is reduced, the heat load of the outdoor side (namely, the condensation side) is indirectly reduced, the power of the compressor is reduced, and the current value of the whole machine is reduced.

It should be noted that if the operation condition of the mobile air conditioner is worse, for example, the mobile air conditioner is operated in a higher environment, the indoor air outlet can be controlled to operate at a smaller angle in order to further reduce the power of the motor and the indoor evaporation capacity and further reduce the power of the compressor. As an example of one possible implementation manner, when the difference between the acquired ambient temperature and the target temperature threshold is greater than or equal to a second threshold and the duration is greater than the target time, the second angle is controlled as a target value of the indoor-side air outlet, where the second angle is smaller than the first angle.

For example, assuming that the second threshold is 5, when the difference Δ T between the ambient temperature T and the target temperature threshold T0 is greater than or equal to the second threshold, i.e. T ≧ T0+5, and the duration of the scene is greater than the target time (e.g. 1 minute), the second angle can be controlled as the target value of the indoor-side outlet, e.g. the indoor-side outlet angle is further reduced to a second angle, which is smaller than the first angle. From this, when mobile air conditioner's operating condition was abominable, steerable indoor side air outlet was in order more small-angle operation to can further reduce motor power and indoor side evaporation capacity, further reduce compressor power, thereby reduce the complete machine current value.

According to the mobile air conditioner control method provided by the embodiment of the invention, by setting the target temperature threshold value and comparing the environmental temperature in the action space of the mobile air conditioner with the target temperature threshold value, and then the angle of the indoor air outlet of the mobile air conditioner is adjusted based on the difference value of the two, further adjusting the indoor air volume, for example, if the difference between the acquired ambient temperature and the target temperature threshold satisfies a certain condition, if the difference is greater than or equal to the first threshold and less than the second threshold, that is, when the ambient temperature in the working space of the mobile air conditioner is higher than a certain value of the target temperature threshold, the indoor side (i.e., the evaporation side) air volume can be reduced, and by reducing the indoor side (i.e., the evaporation side) air volume, therefore, the heat exchange of the indoor side is reduced, the heat load of the outdoor side (namely the condensation side) is indirectly reduced, the power of the compressor is reduced, and the current value of the whole machine is reduced. That is, under the high-temperature working condition operation of the mobile air conditioner, the aim of reducing the current value of the whole machine for the first time is achieved by reducing the angle of the air outlet at the indoor side; furthermore, chain reaction through reducing indoor side air outlet angle and playing: the air quantity at the inner side (evaporation side) of the room is reduced, the heat exchange at the inner side of the room is reduced, and the heat load at the outer side (condensation side) of the room is indirectly reduced, so that the power of the compressor is reduced, and the purpose of reducing the current value of the whole machine for the second time is achieved.

It should be noted that the mobile air conditioner control method of the embodiment of the present invention is more practical for a dual-motor single-duct mobile air conditioner, but the control method can be extended to a dual-motor dual-duct mobile air conditioner, and the control method of the embodiment of the present invention can be adopted for a split mobile air conditioner, so as to improve the refrigeration operation stability under a high temperature working condition.

In some embodiments of the present invention, the control module 720 is further configured to: and when the difference value between the acquired environment temperature and the target temperature threshold is greater than or equal to a second threshold and the duration is greater than the target time, controlling the second rotating speed as a target value of the indoor motor, wherein the second rotating speed is less than the first rotating speed.

In some embodiments of the present invention, the control module 720 is further configured to: when the difference value between the acquired environment temperature and the target temperature threshold is smaller than a third threshold and the duration time is longer than the target time, controlling the third rotating speed as the target value of the indoor motor, wherein the third threshold is a negative number; the third rotating speed is the initial rotating speed of the indoor motor when the mobile air conditioner is started under the high-temperature working condition; and when the difference value between the acquired environment temperature and the target temperature threshold is greater than or equal to a third threshold and smaller than a second threshold and the duration is greater than the target time, controlling the first rotating speed as the target value of the indoor motor.

In some embodiments of the present invention, the specific implementation process of the control module 720 adjusting the indoor air volume of the mobile air conditioner according to the difference between the obtained ambient temperature and the target temperature threshold may be as follows: determining a target angle of an air outlet at the indoor side of the mobile air conditioner according to the difference value between the acquired environment temperature and the target temperature threshold value; and controlling the angle of the indoor side air outlet according to the target angle so as to adjust the indoor side air quantity of the mobile air conditioner.

In some embodiments of the present invention, the specific implementation process of determining the target angle of the indoor side air outlet of the mobile air conditioner by the control module 720 according to the difference between the obtained ambient temperature and the target temperature threshold may be as follows: when the difference value between the acquired environment temperature and the target temperature threshold is greater than or equal to a first threshold and smaller than a second threshold and the duration time is longer than the target time, determining the first angle as the target angle of the indoor air outlet; the first angle is smaller than the initial angle of the indoor air outlet when the mobile air conditioner is started under the high-temperature working condition; the first threshold is less than the second threshold, and the first threshold and the second threshold are both positive numbers.

In some embodiments of the present invention, the control module 720 is further configured to: and when the difference value between the acquired environment temperature and the target temperature threshold is greater than or equal to a second threshold and the duration time is greater than the target time, controlling the second angle as a target value of the indoor air outlet, wherein the second angle is smaller than the first angle.

According to the control device of the mobile air conditioner, when the mobile air conditioner runs under a high-temperature working condition, the ambient temperature in the action space of the mobile air conditioner can be obtained through the ambient temperature obtaining module, the control module adjusts the indoor air volume of the mobile air conditioner according to the difference value between the obtained ambient temperature and the target temperature threshold, and the target temperature threshold can be understood as the temperature limit value of the environment in the action space when the mobile air conditioner does not exceed the standard and stably runs. Therefore, the invention sets the target temperature threshold value, compares the environmental temperature in the mobile air-conditioning action space with the target temperature threshold value, and adjusts the indoor air volume of the mobile air-conditioning based on the difference value between the two, for example, when the difference value between the acquired environmental temperature and the target temperature threshold value meets a certain condition, if the difference value is larger than or equal to the first threshold value and smaller than the second threshold value, namely the environmental temperature in the mobile air-conditioning action space is higher than a certain value of the target temperature threshold value, the indoor air volume (namely the evaporation side) can be reduced, the heat load on the outdoor side (namely the condensation side) can be indirectly reduced by reducing the indoor air volume, thereby the power of the compressor can be reduced, the current value of the whole machine can be reduced, because the control logic of the embodiment of the invention can be written into the control chip of the mobile air-conditioning, the temperature sensor is matched with the existing temperature sensor of the mobile air conditioner for use, so that the problems of unstable operation and overhigh current value of the mobile air conditioner in a high-temperature environment are solved under the conditions that the overall material cost is not increased and large system change (namely, user experience is not influenced) is not carried out.
