Problems solved by technology

In the cold winter, the outdoor temperature will be very low at night, and the refrigerant in the air-conditioning system in standby state will accumulate in the outdoor heat exchanger. When the air conditioner is started the next day, a large amount of liquid refrigerant will enter the compressor, which will cause compression The machine liquid shock and heating effect become worse, which can be solved by reducing the frequency of the compressor, but the heating rate will be greatly reduced in this solution

Abstract

The invention relates to an air conditioner heating control method and device and an air conditioner and belongs to the technical field of air conditioners. The method comprises the steps: receiving aheating operation instruction; and in response to the heating operation instruction, prohibiting refrigerants stored in a part of heat exchangers of an outdoor unit from entering a compressor, and meanwhile, allowing refrigerants stored in the other heat exchangers of the outdoor unit to enter the compressor, so that the compressor performs heating starting by utilizing the refrigerants flowing out of the other heat exchangers. Through the application, the reliability of high-frequency operation of the compressor can be ensured in a low-temperature environment, so that the refrigerant circulation is accelerated, and the heating effect and speed of the heating starting operation stage of an air conditioning system are further improved.

Description

technical field [0001] The application belongs to the technical field of air conditioning, and in particular relates to a method and device for controlling low-temperature heating of an air conditioner and an air conditioner. Background technique [0002] In winter, air conditioners can be used for heating and heating. Multi-connected air conditioners are mostly installed in public places such as office buildings and shopping malls. The characteristics of these places are that they are used during the day and the air conditioners are on standby at night. In the cold winter, the outdoor temperature will be very low at night, and the refrigerant in the air-conditioning system in standby state will accumulate in the outdoor heat exchanger. When the air conditioner starts the next day, a large amount of liquid refrigerant will enter the compressor, which will cause compression. The machine liquid shock and heating effect become worse, which can be solved by reducing the frequenc...
