An air conditioner four-way valve reversing control method, air conditioner and storage medium

Abstract

An air conditioner four-way valve reversing control method, air conditioner and storage medium provided by the present invention include: when the operating state of the air conditioner meets the preset conditions, obtaining the current pressure relationship between the condensation pressure and the evaporation pressure in the air conditioner, according to The pressure relationship determines the target frequency range of the compressor of the air conditioner; the operating frequency of the compressor of the air conditioner is adjusted according to the target frequency range, and when the operating frequency is adjusted to the target frequency range, the Four-way valve reversing. The present invention determines the target frequency range of the compressor according to the pressure relationship between the condensation pressure and the evaporation pressure in the current air conditioner, adjusts the operating frequency of the compressor to the target frequency range, and then controls the four-way valve to change direction, thereby realizing defrosting. During the defrosting process, the four-way valve can be reversed without shutting down the compressor, which shortens the defrosting time and prevents a large drop in the heating capacity of the air conditioner.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner four-way valve reversing control method, an air conditioner and a storage medium. Background technique [0002] Air conditioner defrosting means that when the air conditioner is heating, frosting may occur. If the defrosting is not timely after the air conditioner is frosted, it will affect the use of the air conditioner. [0003] At present, most air conditioners need to stop the compressor during the defrosting process. During the defrosting process, due to the stop operation of the compressor, the defrosting time is prolonged, and the heating capacity of the air conditioner will also be greatly reduced, which affects the heating effect. [0004] Therefore, there are defects in the prior art and need to be improved and developed. Contents of the invention [0005] Aiming at the above-mentioned defects of the prior art, the present invention provi...
