Air conditioner and air conditioner reversing control method and device, storage medium and processor

Abstract

The invention discloses an air conditioner reversing control method and device, an air conditioner, a storage medium and a processor. The air conditioner reversing control method comprises the steps that the high-pressure temperature of an exhaust port of a compressor (1) and the low-pressure temperature of an air suction port of the compressor (1) are obtained, and the running time of the compressor (1) is obtained after the compressor (1) is started; and under the condition that a four-way valve (2) needs to be reversed, opening and closing of an outdoor fan and the operation frequency of the compressor (1) are controlled according to the temperature difference between the high-pressure temperature and the low-pressure temperature and the operation time, and reversing control over the four-way valve (2) is achieved. According to the scheme, the air conditioner reversing control method has the beneficial effect that when the four-way valve needs to be reversed, starting and stopping or starting and stopping of the fan of the air conditioner and the frequency of the compressor are controlled, the reversing pressure difference of the four-way valve is increased, and therefore success reversing of the four-way valve is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a reversing control method and device for an air conditioner, an air conditioner, a storage medium and a processor, in particular to a logic control method for a four-way valve reversing pressure difference of an air conditioner, devices, air conditioners, storage media and processors. Background technique [0002] The four-way valve is the core reversing component of an air conditioner (such as a heat pump air conditioner). It is the key power component for the flow control and cut-off of the reversing system of the heat pump air conditioner. The piston realizes reversing. The function of the four-way valve is to change the function of the heat pump air conditioner by changing the flow direction of the refrigerant in the heat pump air conditioner, and realize the switching of functions such as cooling, heating or defrosting. However, when the four-way valv...

Problems solved by technology

[0004] The object of the present invention is to provide a reversing control method and device for an air conditioner, an air conditioner, a storage medium, and a processor, so as to solve the problem of the four-way valve if the amount of refrigerant is insufficient when the four-way valve needs to be reversed. The problem of unsuccessful reversing due to insufficient reversing pressure difference can be achieved by controlling the start and stop of the fan of the air conditioner and the frequency of the compressor to increase the reversing pressure of the four-way valve when the four-way valve needs to reversing. Poor, so as to ensure the successful effect of four-way valve reversing
