The air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, a throttling element, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.
The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
The throttling element expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the throttling element and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.
The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and a throttling element may be provided in the indoor unit or the outdoor unit.

When the air conditioner is used specifically, the controller receives the exhaust temperature detected by the first temperature sensor 2, the exhaust temperature is compared with the pre-stored preset exhaust temperature, if the exhaust temperature obtained by the controller through comparison is smaller than or equal to the preset exhaust temperature, the exhaust temperature of the compressor 1 is relatively low, a liquid refrigerant exists in the compressor 1, the controller controls the heating belt to be opened at the moment, the compressor 1 is heated, the liquid refrigerant in the compressor 1 is evaporated and gasified, the phenomenon of liquid impact on the compressor 1 can be effectively avoided, the working reliability of the compressor 1 is improved, and the reliability of the air conditioner is further improved. On the contrary, if the exhaust temperature obtained by the controller through comparison is greater than the preset exhaust temperature, that is, the exhaust temperature of the compressor 1 is relatively high, the liquid refrigerant cannot exist in the compressor 1, and at the moment, the controller controls the heating belt to be closed, so that the increase of energy consumption of the air conditioner caused by long-time opening of the heating belt is avoided.
In some embodiments of the present application, an outdoor heat exchanger 3; the second temperature sensor is used for detecting the temperature of the coil of the outdoor heat exchanger 3, the controller is stored with preset exhaust superheat, the controller can control the heating belt to be opened or closed according to the exhaust superheat and the preset exhaust superheat, and the controller controls the heating belt to be opened or closed by judging the exhaust superheat and presetting the exhaust superheat.

"indicates the flow direction and flow path of the refrigerant in the refrigerant circuit when the compressor is operating in the cooling mode.
The exhaust superheat degree is calculated by subtracting the temperature of the coil pipe from the exhaust temperature, namely the exhaust superheat degree is determined by two temperature parameters, so that the state of the refrigerant in the compressor 1 can be more accurately reflected through the exhaust superheat degree, the heating belt can be more accurately controlled to be opened or closed, and the working reliability of the compressor 1 is further improved.
In a specific using process, the controller can receive the exhaust temperature detected by the first temperature sensor 2 and the coil temperature detected by the second temperature sensor, then the exhaust superheat degree of the compressor 1 is obtained through calculation of the exhaust temperature and the coil temperature, then the exhaust superheat degree is compared with a preset exhaust superheat degree stored in advance, if the exhaust superheat degree obtained through comparison by the controller is smaller than or equal to the preset exhaust superheat degree, namely the exhaust superheat degree of the compressor 1 is relatively low, a liquid refrigerant exists in the compressor 1, at the moment, the controller controls the heating belt to be opened to heat the compressor 1, and the liquid refrigerant in the compressor 1 is evaporated and gasified.
