Abstract

The invention belongs to the technical field of air conditioners, and in particular relates to an indoor unit anti-freezing control method for the air conditioner and the air conditioner. The invention aims to solve the problem that the existing air conditioner not only cannot accurately judge the freezing condition of the indoor unit, but also does not set a corresponding anti-freezing mode according to the different freezing conditions of the indoor unit. The indoor unit anti-freezing control method of the present invention includes: when the air conditioner is in cooling operation, obtaining the fan current of the indoor unit; according to the magnitude of the fan current of the indoor unit, selectively enabling the air conditioner to enter the corresponding anti-freezing mode of the indoor unit; so that The air conditioner of the present invention can select different anti-freezing modes according to different freezing conditions of the indoor unit, so that on the basis of effectively ensuring that the indoor unit can be deiced quickly, it can also effectively avoid the incompatibility of the anti-freezing mode in the operation of the existing air conditioner. It is easy to cause energy waste and poor deicing effect.

Description

technical field

[0001] The invention belongs to the technical field of air conditioners, and in particular relates to an indoor unit anti-freezing control method for the air conditioner and the air conditioner. Background technique

[0002] With the continuous improvement of people's living standards, people have also put forward higher and higher requirements for the living environment. In order to maintain a comfortable ambient temperature, air conditioners have become an essential device in people's lives. Generally, an air conditioner includes an indoor unit, an outdoor unit, and a circulation loop for connecting the indoor unit and the outdoor unit. The heat exchange medium in the air conditioner continuously exchanges heat between the outdoor unit and the indoor unit through the circulation loop, thereby achieving a change in room temperature. Effect. Taking the cooling operation of the air conditioner as an example, the coil of the indoor unit is always at a low tem...
