The air conditioner complete machine comprises an indoor fan and an outdoor compressor, and the working principle is that after outdoor airflow is heated or refrigerated by the compressor, the outdoor airflow is discharged into a room through the fan so as to adjust the room temperature to the set temperature of a user. However, the conventional air conditioner is often too simple in temperature regulation and control, and often controls the operation of the compressor when the indoor temperature is lower than or higher than a temperature set value, so that the operation of the compressor and the fan is stopped after the temperature reaches the temperature set value, and the compressor and the fan are started again after the temperature changes within a certain range, and the cycle is repeated in this way.

However, the compressor and the fan which are caused by the control mode are frequently started and stopped, and compared with the working state that the equipment is always kept running, the compressor and the fan bring greater strain to the equipment, the maintenance of the equipment is not facilitated, and meanwhile, the overall power consumption of the equipment is greatly increased. Moreover, in the control mode, only a short time when the indoor temperature reaches the set temperature is in the state of the set temperature really, then the indoor temperature of the compressor and the fan is gradually reduced due to the temporary closing of the compressor and the fan, and the compressor and the fan are restarted until the difference value between the indoor temperature and the set temperature reaches a certain difference value. And in the period from the temporary shutdown of the compressor and the fan to the restart of the compressor and the fan, the indoor temperature does not reach the set temperature, so that the whole experience of a user is not friendly.

Detailed Description

The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.

Example one

In order to make the control of the air conditioner more meet the use requirements of users, and reduce unnecessary power loss of the air conditioner while ensuring that the indoor temperature is within a certain range of the set temperature, as shown in fig. 1, the invention provides a temperature correction-based air conditioner control method, wherein the air conditioner comprises an indoor fan and an outdoor compressor, the indoor fan comprises a coil, and the method comprises the following steps:

As is well known, there are two general operation modes of an air conditioner, that is, a cooling mode and a heating mode, and for different modes, the control of the compressor according to the relationship between the temperature rise trend of the current indoor real-time temperature value and the temperature setting interval in the present invention is different, in the case of step S31:

The temperature rise curve obtained after the above-mentioned different control for the compressor is applied to the air conditioner is shown in fig. 3 and 4, wherein T0 is the temperature set value, and in the embodiment taking fig. 3 and 4 as an example, the preset value is 2 ℃, that is, the temperature set interval is between T0-1 ℃ and T0+1 ℃.

Referring to the figure, step S31 is described in detail, as shown in fig. 3, when the room temperature is assumed to gradually increase to the upper value of the temperature setting range in the compressor shutdown state in the cooling mode, the system determines that the room temperature reaches the upper limit value, controls the compressor to start, and gradually decreases to the lower value of the temperature setting range. At the moment, the system judges that the room temperature reaches the lower limit value, the compressor is controlled to be shut down, although the compressor is shut down at the moment, the fan is still in an open state (residual temperature at the coil pipe, namely cold air is continuously discharged), the indoor temperature still continues to fall for a period of time, but the wind speed is small at the moment due to the fact that the wind speed of the fan sets logic, the room temperature rises again after a period of time, and the system controls the compressor to be started until the room temperature rises to the upper interval value of the temperature setting interval again.

As shown in fig. 4, in the heating mode, when the room temperature is assumed to gradually increase to the upper interval value of the temperature setting interval in the compressor on state, the system determines that the room temperature reaches the upper limit value at this time, and controls the compressor to stop, and under the control of the fan self control logic (the residual temperature at the coil pipe, that is, the heating air is continuously discharged), the room temperature continues to increase for a period of time, and then gradually decreases to the lower interval value of the temperature setting interval, and at this time, the system is switched in, and the compressor is controlled to start, the temperature decrease trend is slowed down, and the compressor is stopped after the room temperature is gradually increased to the upper interval value of the temperature setting interval.

From the above description and with reference to the drawings, it can be easily seen that under the control of such a reciprocating cycle, the indoor temperature is in the temperature setting range for most of the time in the whole use process, and meanwhile, for the start-stop control of the compressor, compared with the conventional method that the compressor and the fan are shut down when the temperature set value is reached, the number of times of restarting the equipment is greatly reduced, and unnecessary power loss in the starting state is reduced.

In the above description, the wind speed control for the indoor fan is also pointed out, and specifically, the step S2 is followed by the step of:

s32: controlling the wind speed switching of the fan according to the relation between the current indoor real-time temperature value and the temperature setting interval, wherein:

In the invention, the compressor and the fan are separately and independently controlled, and no matter which working state (shutdown and start) the compressor is in, the fan adjusts the wind speed according to the indoor temperature. The first wind speed corresponds to high-speed wind in air conditioner setting, the second wind speed corresponds to medium-speed wind, and the third wind speed corresponds to low-speed wind. Through the control logic, when the difference value between the indoor temperature and the set temperature is large and even outside the temperature setting range, the fan runs at the first wind speed, and when the indoor temperature reaches the set temperature and is between the temperature setting range and the temperature setting value, the fan runs at the second wind speed, so that the indoor temperature can reach the set temperature at the fastest speed.

And after the indoor temperature reaches the set temperature, the fan operates at a third wind speed, so that the smooth change of the indoor temperature is ensured. Meanwhile, when the indoor temperature reaches the corresponding interval value (for example, in a refrigeration mode, the temperature reaches the lower interval value of the temperature setting interval), the compressor stops running at the moment, and the fan still runs at the third wind speed, so that the indoor temperature is changed at a smaller speed, the duration that the indoor temperature is in the temperature setting interval is further prolonged, and better use experience is provided for a user.

Further, the air conditioner further includes an anti-freeze mode in the cooling mode, and in the step S31,

And the air conditioner further includes a cold wind prevention mode in the heating mode, and in the step S32,

Through the setting of the landlord mode and the anti-cold mode, the damage to the air conditioner caused by the freezing of the coil pipe due to the over-low temperature of the coil pipe in the refrigeration mode is avoided, and the damage to the air conditioner caused by the over-high temperature of the coil pipe in the heating mode is also avoided.

Example two

In order to better understand the technical content of the present invention, the present embodiment illustrates the present invention in the form of a system structure, as shown in fig. 2, an air conditioner control system based on temperature correction, the air conditioner includes an indoor fan and an outdoor compressor, the indoor fan includes a coil, and includes:

Further, the air conditioner includes a cooling mode and a heating mode, wherein:

Further, the air conditioner also includes an anti-freeze mode in the cooling mode,

Furthermore, the air conditioner also comprises a cold air prevention mode in the heating mode,

EXAMPLE III

The embodiment shows the technical content of the invention through a specific use case.

In a use scene, under an initial state, the indoor temperature is 33 ℃, the set temperature is 26 ℃, the preset value of the temperature setting interval is 2 ℃, and the corresponding temperature setting interval is 25 ℃ to 27 ℃. Therefore, the indoor temperature is far higher than the upper interval value of the temperature setting interval in the initial state, the compressor is operated at the moment, the fan is operated at the first air speed, and when the indoor temperature is between 26 ℃ and 27 ℃, the fan switches the air speed to the second air speed, so that the temperature reduction rate is reduced.

And when the indoor temperature is reduced to 26 ℃, the fan is switched to the third air speed and is kept. And the compressor is stopped when the indoor temperature reaches 25 ℃, and the fan is still in a third air speed running state at the moment, so that the indoor temperature is ensured to be smoothly changed, and the change rate of the temperature rising again is reduced.

When the indoor temperature is gradually warmed back to between 26 ℃ and 27 ℃, the fan is switched to the second air speed again, and when the indoor temperature rises to 27 ℃, the fan is switched to the first air speed, and meanwhile, the compressor is restarted to operate, and the indoor temperature is rapidly reduced to the temperature setting range together with the fan.

In summary, according to the air conditioner control method and system based on temperature correction described in the present invention, a temperature setting interval is determined according to a temperature setting value, the temperature setting interval is a temperature interval using the temperature setting value as a middle value and using a preset value as an interval range, and the main control module controls the start and stop of the compressor according to a relationship between the temperature rise curve and the temperature setting interval, so that the indoor temperature is in the temperature setting interval in most of the whole use process. The compressor and the fan are respectively and independently controlled, and during the shutdown period of the compressor, the fan still adjusts the air speed according to the relation between the indoor temperature and the temperature setting interval, so that the integral ratio of the time when the indoor temperature is in the temperature setting interval in the use process is prolonged.

Through the application of the anti-freezing mode and the anti-cold air mode, the damage to the air conditioner caused by freezing of the coil due to too low temperature of the coil in the refrigeration mode is avoided, and meanwhile, the damage to the air conditioner caused by too high temperature of the coil in the heating mode is avoided.
