Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The invention provides an air-conditioning sterilization method, and referring to fig. 1, fig. 1 is a schematic flow chart of a first embodiment of the air-conditioning sterilization method, and the method comprises the following steps:

step S10, receiving a sterilization instruction, and controlling the heat exchange assembly to operate in a heating mode;

after receiving the sterilization instruction, performing sterilization operation, and controlling the heat exchange assembly to operate in a heating mode, so that the temperature of the indoor heat exchanger gradually rises to a preset sterilization temperature, which is 56 degrees celsius in this embodiment; the heat exchange assembly comprises a compressor, an outdoor heat exchanger, an indoor heat exchanger, a four-way valve and the like, and the heating mode is an operation mode that the four-way valve is adjusted to be opened and closed, so that the indoor heat exchanger emits heat and the outdoor heat exchanger absorbs heat. The degerming instruction may be sent by a user, or may be preset and sent by the processor when a certain time arrives.

Step S20, acquiring a compressor pressure parameter at intervals of a first preset time;

the compressor pressure parameters include a discharge pressure value of a compressor discharge port and a suction pressure value of a compressor intake port.

Step S30, judging whether the compressor pressure parameter meets a preset pressure standard;

the preset pressure criterion may comprise a high pressure criterion, i.e. a criterion for the value of the discharge pressure, a low pressure criterion, i.e. a criterion for the value of the suction pressure, or a criterion for the relation between the two, etc.

And step S40, if the compressor pressure parameter does not meet the preset pressure standard, controlling the heater to heat after the compressor pressure parameter is operated for a second preset time, so that the temperature of the indoor heat exchanger is greater than or equal to the preset degerming temperature.

The temperature of the indoor heat exchanger may be a surface temperature of the indoor coil, a temperature of a refrigerant in the indoor coil, or a temperature of air in a preset area of the indoor coil. It is understood that steps S10-S40 are in the process of increasing the temperature of the indoor heat exchanger from the temperature before the heat exchange module is operated in the heating mode to the preset sterilization temperature, and before the temperature of the indoor heat exchanger reaches the preset sterilization temperature, the operating parameters of the compressor in the heat exchange module, such as the operating frequency and the exhaust pressure, are gradually changed to make the temperature of the indoor heat exchanger reach the preset sterilization temperature. The maintaining of the operation of the compressor pressure parameter means that the operation parameter of the current heat exchange assembly is kept unchanged, so that the current compressor pressure parameter is kept unchanged, because the compressor pressure parameter exceeds the pressure parameter required by the preset pressure standard at the moment, if the compressor working parameter is still changed to enable the heat exchange assembly to raise the temperature at the moment, the compressor pressure parameter can further exceed the preset pressure standard, and therefore, the heater is controlled to heat, so that the pressure parameter of the compressor is prevented from further exceeding the preset pressure standard while the temperature of the indoor heat exchanger reaches the preset degerming temperature. After the compressor is operated for the second preset time according to the pressure parameter of the compressor, the heater is controlled to heat in order to maintain the stability of the system after the system is stable and then the heater is used for heating. The heater may be a PTC heater or an infrared heater, etc.

In the sterilization process, the heat exchange assembly is controlled to operate in a heating mode, so that the temperature of air flowing through the indoor heat exchanger can be increased, and bacteria in the air can be killed through high temperature; by judging whether the pressure parameter of the compressor meets the preset pressure standard or not, the running state of the compressor can be kept unchanged when the pressure value of the compressor does not meet the preset pressure standard, so that the conditions of abrasion caused by reduction of the gas transmission coefficient of the compressor and reduction of the viscosity of lubricating oil are avoided, and the service life of a product is prolonged; the heater is controlled to heat, so that the pressure value of the compressor does not meet the operating standard of the compressor, and the heater can maintain higher temperature to sterilize.

Further, in a second embodiment of the air conditioner sterilization method according to the present invention proposed based on the first embodiment of the present invention, the compressor pressure parameter includes: a discharge pressure value of the compressor discharge port and a suction pressure value of the compressor intake port, wherein the step S30 includes the steps of:

dividing the exhaust pressure value by the suction pressure value to calculate the compression ratio of the compressor;

and judging whether the compression ratio is less than or equal to a preset compression ratio.

When the outdoor temperature is low, the suction pressure value of the air inlet of the compressor is reduced, the compression ratio of the compressor is increased, and when the compression ratio of the compressor exceeds the specified compression ratio value of the compressor, the adverse effects of reduction of the gas transmission coefficient of the compressor, abrasion caused by reduction of the viscosity of lubricating oil and the like can occur. Therefore, in the heating process, it is necessary to determine the compression ratio of the compressor. The discharge pressure value and the suction pressure value may be measured by a pressure sensor. It should be noted that the preset compression ratio may be a specified compression ratio value of the compressor, and in this embodiment, the preset compression ratio is a value obtained by subtracting a buffering margin from the specified compression ratio value of the compressor, so that when it is detected that the compression ratio exceeds the preset compression ratio, the compressor is still in a normal operation state, and a person skilled in the art of buffering margin may adjust the buffering margin according to actual needs, the frequency of obtaining a pressure parameter of the compressor, the structure of the compressor, and the like.

In the heating process, whether the compression ratio of the compressor is smaller than or equal to the preset compression ratio is judged, so that the adverse effects of reduction of the gas transmission coefficient of the compressor, abrasion caused by reduction of viscosity of lubricating oil and the like caused by the fact that the compression ratio exceeds the specified compression ratio of the compressor are avoided, and the reliability of the air conditioning system is improved.

Further, referring to fig. 2, in a third embodiment of the air-conditioning sterilizing method of the present invention proposed based on the first embodiment of the present invention, the compressor pressure parameters include: a discharge pressure value of the compressor discharge port and a suction pressure value of the compressor intake port, wherein the step S30 includes the steps of:

step S31, dividing the exhaust pressure value by the suction pressure value to calculate the compression ratio of the compressor;

step S32, acquiring a preset low-voltage upper limit value;

and step S33, judging whether the compression ratio is less than or equal to a preset compression ratio and judging whether the suction pressure value is less than or equal to the preset low-pressure upper limit value.

Referring to fig. 3, the step S40 includes:

and step S41, if the compression ratio is greater than a preset compression ratio, or the suction pressure value is greater than the preset low-pressure upper limit value, controlling the heater to heat after the compressor operates for a second preset time according to the pressure parameter of the compressor, so that the temperature of the indoor heat exchanger is greater than or equal to a preset degerming temperature.

And step S42, if the compression ratio is less than or equal to a preset compression ratio and the suction pressure value is less than or equal to the preset low-pressure upper limit value, continuing to control the heat exchange assembly to operate in a heating mode.

When the outdoor temperature is high, the suction pressure value of the air inlet of the compressor is increased, and when the suction pressure value exceeds the highest low pressure value allowed by the compressor, the steam flow on the low-pressure side is overlarge, so that the compressor is abraded and other adverse effects are caused. Therefore, it is necessary to determine the suction pressure value of the compressor during heating. The preset low-pressure upper limit value is obtained by subtracting a buffering allowance from the highest low-pressure value allowed by the compressor, so that when the suction pressure value is detected to be larger than the preset low-pressure upper limit value, the compressor is still in a normal running state, and the buffering allowance can be adjusted according to the frequency of the obtained pressure parameter of the compressor and the like.

When the compression ratio is larger than the preset compression ratio or the suction pressure value is larger than the preset lower-pressure upper limit value, the compressor is indicated to be in an abnormal working state at the moment, if the operation parameters are continuously increased, the compressor enters the abnormal working state, therefore, the current running state needs to be maintained, the compression ratio or the suction pressure value is prevented from being further increased, and after the system is stabilized, the heater is controlled to heat. In the present embodiment, the compressor is taken as an example, and when the compressor operates according to the compressor pressure parameter, components including the indoor heat exchanger, the outdoor heat exchanger, the indoor fan, and the like are operated according to the same operation parameter as the compressor pressure parameter.

Under the condition that the compression ratio is smaller than or equal to a preset compression ratio and the suction pressure value is smaller than or equal to the preset low-pressure upper limit value, the condition indicates that the compressor is in a normal operation state at the moment and is still in the normal operation state within a certain time, and therefore the heat exchange assembly can be continuously controlled to operate in the heating mode in the current operation mode.

Whether the compressor is in a normal running state or not is judged according to two judging conditions of the compression ratio and the suction pressure value, so that the adverse consequences that the gas transmission coefficient of the compressor is reduced, the viscosity of lubricating oil is reduced, the compressor is abraded and the like due to the fact that the compression ratio exceeds the specified compression ratio value of the compressor are avoided, or the adverse consequences that the steam flow on the low-pressure side is increased, the compressor is abraded and the like due to the fact that the suction pressure value exceeds the highest low pressure value allowed by the preset compressor are avoided, and the reliability of the air conditioning system is improved.

Further, referring to fig. 4, in the fourth embodiment of the air-conditioning sterilizing method of the present invention proposed based on the first embodiment of the present invention, the step S40 includes:

step S43, if the compressor pressure parameter does not accord with the preset pressure standard, the compressor is maintained to operate according to the compressor pressure parameter;

step S44, after the compressor pressure parameter is operated for a second preset time, the current indoor heat exchanger temperature is obtained, and the difference value between the current indoor heat exchanger temperature and the preset degerming temperature is calculated;

and step S45, controlling the heater to operate at a preset power corresponding to the difference.

If the heaters are controlled to be heated with the same power, the heating time is different when the temperatures to be heated are different, in order to improve the heating efficiency, a control table in which the difference value corresponds to the preset power of the operation of the heaters one to one is preset, and it can be understood that the larger the difference value is, the larger the corresponding preset power is, when the heaters are required to be heated, the difference value between the current indoor heat exchanger temperature and the preset sterilization temperature is firstly obtained, the preset power corresponding to the difference value is obtained through the obtained difference value table lookup, and then the heaters are controlled to operate with the preset power.

In the embodiment, the corresponding preset power is set for different difference values, so that the heater operates at the preset power during operation, and the heating efficiency is improved.

Further, in a fifth embodiment of the air conditioner sterilization method according to the present invention proposed based on the first embodiment of the present invention, the compressor pressure parameters include: the exhaust pressure value and the suction pressure value, and the step S20 includes:

acquiring saturated gas phase pressure data, the current temperature of the indoor heat exchanger and the current temperature of the outdoor heat exchanger;

acquiring the exhaust pressure value according to the saturated gas phase pressure data and the current temperature of the indoor heat exchanger;

and acquiring the suction pressure value according to the saturated gas phase pressure data and the current temperature of the outdoor heat exchanger.

In practical application, it is difficult to directly obtain the discharge pressure value and the suction pressure value of the compressor, so that the discharge pressure value and the suction pressure value of the compressor can be indirectly obtained through the saturated gas phase pressure of the refrigerant. The saturated vapor pressure data refers to the corresponding saturated vapor pressure of the refrigerant adopted in the air conditioning system at different temperatures, and it should be noted that the saturated vapor pressure data is different according to different refrigerants, so that when the air conditioning system leaves a factory, the corresponding saturated vapor pressure data can be stored in the processor according to the type of the actually applied refrigerant.

After the current temperature of the indoor heat exchanger is obtained, the saturation gas phase pressure corresponding to the current temperature of the indoor heat exchanger is searched in the saturation gas phase pressure data, and the exhaust pressure of the compressor and the saturation gas phase pressure of the indoor heat exchanger have certain pressure drop, so that the exhaust pressure value of the compressor can be obtained by adding a pressure drop allowance to the obtained saturation gas phase pressure.

After the current temperature of the outdoor heat exchanger is obtained, the saturation gas phase pressure corresponding to the current temperature of the outdoor heat exchanger is searched in the saturation gas phase pressure data, and a certain pressure drop is considered to exist between the suction pressure of the compressor and the saturation gas phase pressure of the outdoor heat exchanger, so that the suction pressure value of the compressor can be obtained by subtracting a pressure drop allowance from the obtained saturation gas phase pressure, and the pressure drop allowance is specifically set according to the condition of the air conditioning system.

In the embodiment, the saturated gas phase pressure of the refrigerant in the indoor heat exchanger/outdoor heat exchanger is obtained through the current temperature of the indoor heat exchanger/outdoor heat exchanger, so that the exhaust pressure value/the suction pressure value of the compressor is obtained, and the exhaust pressure value/the suction pressure value of the compressor can be conveniently and accurately obtained.

Further, in a sixth embodiment of the air conditioner sterilization method according to the present invention proposed based on the first embodiment of the present invention, the step S40 is followed by:

judging whether the running time of the indoor coil pipe at the preset degerming temperature reaches the preset degerming time or not;

if yes, the sterilization operation is ended.

In this embodiment, the preset sterilization duration is 30 minutes. When the time length of the indoor heat exchanger running at the preset sterilization temperature reaches the preset sterilization time length, the germs can be considered to be cleared, the sterilization ending operation refers to the operation state of the air conditioner adjusted to be before the sterilization instruction is received to operate the sterilization operation, for example, before the sterilization operation is operated, the air conditioner is in a standby state, and the sterilization ending operation is the operation state of the air conditioner adjusted to be in the standby state.

After the germs are removed, the sterilization operation is finished, the running state of the air conditioner is restored, and the influence on normal use of a user is avoided.
