Problems solved by technology
[0005] In order to solve the above-mentioned problems in the prior art, that is, in order to solve the problem that the existing air conditioners are difficult to accurately judge the freezing condition of the indoor unit only based on the temperature of the inner coil, and the corresponding anti-freezing conditions have not been set according to the different freezing conditions of the indoor unit. Mode problem, the present invention provides an indoor unit anti-freezing control method for an air conditioner, the indoor unit anti-freezing control method includes: when the air conditioner is in cooling operation, obtain the fan current and Coil temperature: when the coil temperature of the indoor unit is lower than the freezing temperature of the coil of the indoor unit, the air conditioner is selectively entered into the corresponding anti-freezing mode of the indoor unit according to the fan current of the indoor unit

The invention belongs to the technical field of air conditioners, in particular to an anti-freezing control method used for an indoor machine of an air conditioner and an air conditioner. The objective of the invention is to solve the problem that the prior air conditioner is difficult to judge the freezing condition of the indoor machine accurately just by the temperature of an inner coiler andincapable of setting a corresponding anti-freezing mode according to different freezing conditions of the indoor machine. The anti-freezing control method used for the indoor machine of the air conditioner comprises the steps of obtaining fan electric current and coiler temperature of the indoor machine during refrigeration operation of the air conditioner; and selectively enabling the air conditioner to enter a corresponding indoor machine anti-freezing mode according to the fan electric current size of the indoor machine in the situation that the coiler temperature of the indoor machine is less than the coiler freezing temperature of the indoor machine to make the air conditioner be capable of selecting different anti-freezing modes according to the freezing condition of the indoor machine, so that the problem is effectively avoided on the basis of rapid deicing that it is prone to cause energy waste and the deicing effect is not good due to the bad correspondence of the anti-freezing mode that the air conditioner runs.
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...
