And the degerming cabin air conditioner determines an opening compensation value according to the current operating frequency, so that the opening compensation value is adaptive to the current operating frequency of the compressor. The opening degree of the electronic expansion valve is compensated through the opening degree compensation value, and the accuracy of the target opening degree is improved.
With reference to fig. 4, an embodiment of the present disclosure provides a method for sterilization of an air conditioner of a sterilization cabin, including:

Wherein b is an opening compensation value, and f is the current operating frequency.
The basic opening degree can be a self-defined opening degree of electronic expansion, and the sum of the basic opening degree and the opening degree compensation value is smaller than or equal to the maximum opening degree.
By adopting the method for degerming the air conditioner of the degerming cabin, which is provided by the embodiment of the disclosure, the opening compensation value is determined according to the current operating frequency of the compressor, so that the opening compensation value can represent the amount of the refrigerant entering the indoor heat exchanger under the current operating frequency. The target opening degree is determined by the sum of the basic opening degree value and the opening degree compensation value of the electronic expansion valve, so that the target opening degree is adaptive to the current operation frequency of the compressor, and the accuracy of the target opening degree is improved.
Optionally, the sterilization chamber air conditioner increases an operation frequency of the compressor and decreases a rotation speed of the indoor fan, comprising: the air conditioner of the sterilization chamber improves the operation frequency of the compressor to the defrosting operation frequency and adjusts the rotating speed of the indoor fan to the lowest rotating speed.
Therefore, the air conditioner of the sterilization cabin improves the running frequency of the compressor to the defrosting running frequency and adjusts the rotating speed of the indoor fan to the lowest rotating speed in the third sterilization process. At the moment, the temperature of the refrigerant is lower when the refrigerant is condensed by the outdoor heat exchanger and then enters the indoor heat exchanger, and the temperature of the indoor heat exchanger can be sharply reduced due to the fact that the indoor space basically has no evaporation effect, and bacterial colonies remaining on fins of the evaporator are killed.
Optionally, the sterilizing compartment air conditioner controls the temperature of the indoor heat exchanger to be greater than or equal to a set temperature, and comprises: the degerming cabin air conditioner improves the overload protection temperature of the inner coil pipe, operates a heating mode, improves the operating frequency of the compressor, and reduces the rotating speed of the indoor fan, so that the temperature of the indoor heat exchanger is greater than or equal to the set temperature within the set time.
Therefore, the degerming cabin air conditioner controls the operation to heat, improves the operation frequency of the compressor, reduces the rotating speed of the indoor fan, and reduces condensation of the refrigerant in the indoor heat exchanger as much as possible, namely the temperature attenuation from the inlet to the outlet of the refrigerant is reduced after the refrigerant passes through the hairpin pipe of the indoor heat exchanger. The indoor heat exchanger can be always kept at a higher temperature, so that the temperature of the indoor heat exchanger is greater than or equal to the set temperature within the set time. For example, the operation heating is controlled, the operation frequency of the compressor is increased, the rotating speed of an indoor fan is reduced, the temperature of the indoor heat exchanger is kept above 60 ℃ for more than 30min, so that the indoor heat exchanger has a high-temperature heating effect on circulating air passing through the air inlet side to the indoor heat exchanger, the air outlet side is also kept above 60 ℃, and a part of flora in the indoor circulating air is killed. In addition, the overload protection temperature of the inner coil is increased, and the phenomenon that the overload protection is triggered to reduce the frequency of the compressor due to overhigh temperature of the inner coil is avoided.
Referring to fig. 5, an embodiment of the present disclosure provides a method for sterilization of an air conditioner of a sterilization cabin, including:
and S51, the air conditioner of the sterilization cabin reduces the frequency reduction temperature of anti-freezing protection, operates a refrigeration mode, improves the operation frequency of the compressor and reduces the rotating speed of the indoor fan under the condition that the first sterilization process and the second sterilization process are sequentially executed.
And S02, determining the target opening degree of the electronic expansion valve by the air conditioner of the sterilization cabin according to the current running frequency of the compressor.
And S03, adjusting the opening of the electronic expansion valve to a target opening by the sterilization cabin air conditioner.
The first sterilization process comprises the steps of controlling an indoor heat exchanger to frost firstly and then defrosting; the second degerming process comprises the step of controlling the temperature of the indoor heat exchanger to be greater than or equal to the set temperature.
By adopting the method for degerming the air conditioner of the degerming cabin, when the air conditioner of the degerming cabin performs the third degerming process, the evaporation and heat absorption principle of the refrigerant in the air conditioner of the degerming cabin is fully utilized, the running frequencies of different compressors are responded, the amount of the refrigerant entering the heat exchanger in the air conditioner of the degerming cabin is adjusted, and the refrigerant is fully evaporated and absorbs heat. When the indoor heat exchanger is rapidly cooled, the frequency reduction temperature of the anti-freezing protection is reduced, so that abnormal shutdown such as anti-freezing protection or over-current protection is avoided. The problem that the temperature of the indoor heat exchanger is slow due to incomplete evaporation of the refrigerant caused by excessive refrigerant entering the indoor heat exchanger is solved. Therefore, the temperature of the indoor heat exchanger is quickly reduced to a lower temperature from the high temperature of the second sterilization process, the colony on the surface of the indoor heat exchanger is killed in the simulated bus sterilization process, and the sterilization effect of the sterilization cabin air conditioner is improved.
Optionally, the sterilization chamber air conditioner reduces a de-icing temperature for anti-freeze protection, comprising: the air conditioner of the sterilization cabin determines a temperature compensation value corresponding to a set temperature according to a preset corresponding relation; the degerming cabin air conditioner calculates the difference value between the current frequency reduction temperature value and the temperature compensation value, and determines the difference value as the target frequency reduction temperature; and adjusting the frequency reduction temperature to the target frequency reduction temperature by the air conditioner of the sterilization cabin.
The frequency reduction temperature is the preset temperature of the inner coil, namely if the temperature of the inner coil is lower than the frequency reduction temperature, the anti-freezing protection mode is started.
Therefore, the air conditioner of the sterilization cabin determines a temperature compensation value corresponding to the set temperature according to the preset corresponding relation, compensates the current previous frequency reduction temperature value through the temperature compensation value to determine the target frequency reduction temperature, adjusts the frequency reduction temperature to the target frequency reduction temperature, avoids abnormal shutdown such as anti-freezing protection or over-current protection and the like through reducing the frequency reduction temperature of the anti-freezing protection, and improves the user experience. For example, the anti-freezing protection is protection control generally adopted in the industry at present, and the down-conversion temperature is generally set to be about 6 ℃.
