Abstract

The invention provides an operation control method and device, an air conditioner, and a computer-readable storage medium. The operation control method comprises the following steps: in the heating mode, detecting specified operation parameters of a compressor at preset time intervals; when determining that the heating capacity is lowered according to the specified operation parameters, judging whether the operation frequency of the compressor is higher than or equal to the preset operation frequency; and adjusting operation parameters of specified parts of the air conditioner according to theoperation frequency judgement result, so as to reduce the number of defrosting operations in the heating mode. The specified operation parameters comprise at least one of the exhaust temperature of the compressor, the load current of the compressor, and the power of the compressor. Through the technical scheme, the compressor operation reliability and stability can be improved, the defrosting frequency can be reduced, the defrosting duration can be shortened, and the user experience can be effectively improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an operation control method, an operation control device, an air conditioner and a computer-readable storage medium. Background technique [0002] In the heating mode, the air conditioner usually pursues fast heating speed, so the operating frequency of the compressor is set to be high. [0003] In the related technology, due to the high-frequency operation of the compressor, the pressure difference in the system is large, which in turn leads to frequent frosting and defrosting of the outdoor heat exchanger, which in turn leads to incoherent heating output of the indoor heat exchanger to the indoor environment, which seriously affects users. use experience. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. [0005] Therefore, an object of the present inventio...
