Air conditioner, control method and device of air conditioner and readable storage medium

Abstract

The invention discloses a control method of an air conditioner, the air conditioner is provided with a bypass valve connected in parallel with an electronic expansion valve between an indoor heat exchanger and an outdoor heat exchanger, one end of the bypass valve is connected between the indoor heat exchanger and the electronic expansion valve, and the other end of the bypass valve is communicated with the joint of a first heat exchange part and a second heat exchange part of the outdoor heat exchanger. The method comprises the steps that when the air conditioner operates in a heating mode, heating state parameters of the air conditioner are obtained; and when the heating state parameters meet the starting condition of the heating capacity improving operation, the bypass valve is controlled to be opened. The invention further discloses a control device of the air conditioner, the air conditioner and a computer readable storage medium. The invention aims to improve the heating capacity of the air conditioner so as to meet the thermal comfort of the indoor environment.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, and in particular, to a control method of an air conditioner, a control device of an air conditioner, an air conditioner and a computer-readable storage medium. Background technique [0002] With the development of economy and technology, air conditioners are more and more widely used in our daily life. As a main indoor environment temperature adjustment equipment, the air conditioner is not only used for cooling the indoor environment, but also widely used for heating the indoor environment. The heat exchanger is in an evaporative state. [0003] However, the air conditioner generally uses the heating function in the low temperature environment, and the outdoor heat exchanger as the evaporator has a poor heat exchange effect in the low temperature environment, which is easy to cause problems such as frosting of the outdoor unit and too low return air temperature in the refriger...

AI Technical Summary

Problems solved by technology

[0003] However, air conditioners generally use the heating function in low-temperature environments. The outdoor heat exchanger used as an evaporator has poor heat transfer effect in low-temperature environments, which may easily lead to problems such as frosting of the outdoor unit and low return air temperature in the refrigerant system. As a result, the heating capacity of the air conditioner is low and cannot meet the heating comfort requirements of the indoor environment
