Air conditioner, heating control method and storage medium for air conditioner

Abstract

The invention discloses an air conditioner, a heating control method of the air conditioner and a storage medium. The heating control method of the air conditioner divides the refrigerant passing through the evaporator into two paths through a flow splitting module, and uses an enthalpy injection electronic expansion valve to divide the refrigerant into two paths. One of the refrigerants is throttled and depressurized, and then based on the difference between the indoor pipeline temperature and the exhaust temperature of the compressor, the opening parameter of the enthalpy-injected electronic expansion valve is controlled, thereby controlling the amount of refrigerant output by the enthalpy-injected electronic expansion valve. Then control the amount of refrigerant in the one-way refrigerant that is throttling and reducing pressure, thereby controlling the amount of refrigerant for heat exchange between the one-way refrigerant that is throttling and reducing pressure and the other refrigerant, realizing the effect of enthalpy injection, increasing the heating capacity of the air conditioner, and reducing the cooling capacity of the air conditioner. The noise during high-frequency operation improves the user experience.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner, a heating control method for the air conditioner and a computer-readable storage medium. Background technique [0002] In low temperature environments, such as -15 degrees, -20 degrees or even lower environments, some areas such as the United States and Canada require a large heating output. At present, the air-conditioning system increases the heating capacity through high-frequency operation at low temperature, but this will result in a relatively low low pressure, and the output heating capacity is limited, which cannot meet the needs of users. Moreover, when operating at high frequency, the noise generated by the air conditioner is increased and the user experience is reduced.
