Embodiment 1

[0040]In one embodiment, an air conditioner is provided, such asfigure 1 As shown, the air conditioner includes a compressor 1, a four-way valve 2, an outdoor unit heat exchanger 3, a throttle assembly 4, an indoor unit electronic expansion valve 5, an indoor unit heat exchanger 6, a gas-liquid separator 7, an electronic expansion Valve 8. The exhaust port of the compressor 1 is connected to the D end of the four-way valve 2, and the C end of the four-way valve 2 is connected to the air collecting pipe of the outdoor unit heat exchanger 3. The outdoor unit heat exchanger 3 is connected to the throttle component 4, the outlet of the throttle component 4 is connected to the indoor unit heat exchanger 6, and the outlet of the indoor unit heat exchanger 6 is connected to the E end of the four-way valve 2. Connection, the S end of the four-way valve 2 is connected with the inlet of the gas-liquid separator 7, and the outlet of the gas-liquid separator 7 is connected with the suction port...

Embodiment 2

[0043]In one embodiment, an air conditioner control method is provided. The air conditioner control method can be applied to an air conditioner. A processor in the air conditioner can execute the control method to control the air conditioner. Please refer tofigure 2 ,figure 2 It is a flowchart of a preferred embodiment of the air conditioning control method provided by the present invention. The method includes:

[0044]S100: When the air conditioner load rate, the air conditioner compressor exhaust superheat degree and the outdoor ambient temperature meet preset conditions, obtain the current opening degree of the electronic expansion valve, the heat balance branch temperature and the heat balance branch pressure.

[0045]In specific implementation, when the cooling demand of the air conditioner is small and the outdoor ambient temperature is low, the pressure of the compressor return port and the gas-liquid separator inlet pressure will decrease, and the evaporation temperature of the i...

Embodiment 3

[0078]Based on the above embodiments, the present invention also provides an air conditioner, the principle block diagram of which can be asimage 3Shown. The air conditioner includes a processor, a memory, a network interface and a user interface connected through a system bus. Among them, the processor of the air conditioner is used to provide calculation and control capabilities.

Abstract

The invention discloses an air conditioner control method, an air conditioner and a storage medium. The method comprises the steps that the current opening degree of an electronic expansion valve, thetemperature of a heat balance branch and the pressure of the heat balance branch are obtained when the load rate of the air conditioner, the exhaust superheat degree of an air conditioner compressorand the outdoor environment temperature meet the preset conditions; the target opening degree of the electronic expansion valve is determined according to the current opening degree of the electronicexpansion valve, the temperature of the heat balance branch and the pressure of the heat balance branch; and the electronic expansion valve is adjusted according to the target opening degree of the electronic expansion valve. According to the air conditioner control method, the air conditioner and the storage medium, when it is judged that the surface of a heat exchanger of an indoor unit is proneto frosting, the opening degree of the electronic expansion valve is adjusted according to the temperature of the heat balance branch and the pressure of the heat balance branch, the amount of a refrigerant entering the heat exchanger of the indoor unit is reasonably distributed through the opening degree of the electronic expansion valve, frosting on the surface of the heat exchanger of the indoor unit is avoided, and the air outlet temperature of the indoor unit is made more stable. Accurate temperature control of the air conditioner is realized.

Description

Technical field[0001]The invention relates to the technical field of air conditioners, in particular to an air conditioner control method, an air conditioner and a storage medium.Background technique[0002]With the rapid development of the communication industry, the number of mobile communication base stations is also rapidly increasing. The rapid expansion of communication base stations has driven the market demand for base station air conditioners. Due to its large capacity, small footprint, wide coverage, and easy installation and maintenance, multi-line air conditioners are more and more users choosing base station air conditioners to cool and dehumidify base station equipment to ensure that the base station equipment operates in the best environment.[0003]Conventional multi-line air conditioners are mainly used to adjust the comfort of civil buildings, and the cooling operation range is usually above 15°C. When multi-line air conditioners are used as base station air conditione...
