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

Abstract

The invention relates to an air conditioner control method and device, an air conditioner and a storage medium. The method comprises the following steps that 1, when it is detected that the air conditioner starts heating, the current environment temperature is obtained; 2, if it is determined that the air conditioner is in a low-temperature environment according to the current environment temperature, whether the air conditioner meets the four-way valve reversing delay condition or not is judged; and 3, when it is determined that the air conditioner meets the four-way valve delayed reversing condition, a four-way valve is controlled to conduct delayed reversing, and after the four-way valve conducts reversing, the air conditioner operates in a heating mode. By the adoption of the method, when the air conditioner starts heating in the low-temperature environment, the four-way valve is controlled to delay reversing to prolong the refrigeration operation time, so that the evaporation pressure is improved, the condensation pressure is reduced, the compression ratio in a compressor is reduced, the refrigerant circulation amount and lubricating oil flowing away along with a refrigerant are reduced, the problem of oil shortage of the compressor is solved. Other parts do not need to be added, so that the loss of the compressor is reduced while the development cost of the air conditioner is reduced, and the stable operation of the air conditioner is ensured.

Description

technical field [0001] The present application relates to the technical field of air conditioners, in particular to an air conditioner control method and device, an air conditioner and a storage medium. Background technique [0002] With the development of air conditioner technology and the wide application of different types of air conditioners, such as household air conditioners and commercial multi-connected air conditioners, in people's life and work, the performance requirements of air conditioners in the actual application process are increasing. [0003] However, after the compressor of the air conditioner is placed in a low temperature environment for a long time, when it needs to be turned on to start heating, due to the high miscibility ratio between the liquid refrigerant and the lubricating oil at low temperature in the low temperature environment, a large amount of lubricating oil will be dissolved with the liquid refrigerant after mutual dissolution. The compre...

Problems solved by technology

[0005] However, since the power of the electric heating belt is high enough to effectively heat the compressor oil, the traditional solution not only needs to add an additional electric heating belt, but also consumes a lot of power to maintain the high-power operation of the electric heating belt, so there are still The problem of high development and operation costs of air conditioners
