The invention provides an enthalpy-increasing air conditioner control method and device, an enthalpy-increasing air conditioner and a computer storage medium. The enthalpy-increasing air conditioner control method comprises the following steps: if an expansion valve on an auxiliary road of the enthalpy-increasing air conditioner is in an open state, exhaust parameters of a first compressor and exhaust parameters of a second compressor in the enthalpy-increasing air conditioner are obtained; the exhaust parameters at least comprise one of exhaust temperature and exhaust pressure; and if the exhaust temperature of the first compressor is higher than the exhaust temperature of the second compressor, or the exhaust pressure of the first compressor is higher than the exhaust pressure of the second compressor, the operation frequency of the first compressor is reduced, and / or the operation frequency of the second compressor is increased. According to the enthalpy-increasing air conditioner control method provided by the invention, when the exhaust parameters of the two compressors are unequal, the output capacities of the two compressors are balanced by reducing the operation frequency of the compressor with the higher exhaust parameters or increasing the operation frequency of the compressor with the lower exhaust parameters; and therefore, stable operation of the double-compressor system in an enthalpy increasing state is guaranteed.
Description
technical field [0001] The embodiments of the present application relate to the technical field of air conditioners, and in particular to a method and device for controlling an enthalpy-increasing air conditioner, an enthalpy-increasing air conditioner, and a computer storage medium. Background technique [0002] Enthalpy increase, that is, air injection to increase enthalpy, usually means that in the air conditioning system, the condensed high-pressure liquid refrigerant is divided into two paths, one path flows directly to the evaporation side through the main path, and the other path passes through the auxiliary path, and returns to the enthalpy loop through the enthalpy increase circuit. To the compressor, and perform two-stage compression in the compressor to increase the output of the compressor, thereby improving the heating capacity of the air conditioning system at low temperatures. In order to further improve the output capacity of the air-conditioning system, the ...
