Problems solved by technology

[0003] However, after the refrigerant is completely recovered to the outdoor unit, there will be no refrigerant in the heat exchanger of the indoor unit at this time, which will cause the internal pressure of the heat exchanger of the indoor unit to drop Less than the external pressure, the pressure difference between the inside and outside of the heat exchanger of the indoor unit is too large, which affects the life of the heat exchanger of the indoor unit

Abstract

The invention provides an air conditioner control method and device, an air conditioner and a computer readable storage medium, and the air conditioner control method comprises the steps that if the air conditioner receives a closing instruction in a non-heating mode, the current copper pipe surface temperature and the current indoor environment temperature of an indoor unit heat exchanger are obtained; according to the current copper pipe surface temperature and the current indoor environment temperature, the valve opening degree of an electronic expansion valve of the air conditioner is controlled, so that part of a refrigerant recycled from an indoor unit to an outdoor unit in the air conditioner flows back to the indoor unit; and after preset opening and closing time, the air conditioner is closed. The valve opening degree of the electronic expansion valve can be controlled, and finally the refrigerant completely recycled to the outdoor unit partially flows back to the indoor unit. The situation that after the refrigerant is completely recycled to the outdoor unit, the heat exchanger of the indoor unit is not provided with the refrigerant, the pressure on the inner side and the outer side of the heat exchanger of the indoor unit is too large, and damage is liable to happen is avoided. Therefore, the service life of the heat exchanger of the indoor unit can be prolonged.

Description

technical field [0001] The present application relates to the field of air conditioners, and specifically relates to an air conditioner control method and device, an air conditioner, and a computer-readable storage medium. Background technique [0002] In the prior art, the air conditioner usually needs to rely on a corresponding refrigerant to complete the heat exchange to complete the heat exchange. Take air conditioner refrigeration as an example. In the cooling mode of the air conditioner, the low-pressure steam of the refrigerant in the refrigeration system is sucked into the compressor and compressed into high-pressure steam, and then discharged to the condenser. At the same time, the outdoor air drawn by the axial fan flows through the condenser, taking away the heat released by the refrigerant, and condensing the high-pressure refrigerant vapor into a high-pressure liquid. The high-pressure liquid is sprayed into the evaporator after passing through the filter and t...
