Problems solved by technology

[0007] The present invention was invented to solve the disadvantages of the above-mentioned technologies, and its purpose is to provide a method that can continue to operate even if the temperature of the indoor heat exchanger becomes icy due to the temperature of the indoor pipe being lower than the specified temperature. Indoor heat exchanger icing suppression method for an air conditioner that suppresses icing on the surface of the indoor heat exchanger at the same time as the compressor

Abstract

This invention is the indoor heat exchanger icing suppressing method for air conditioner. When the temperature of refrigerants pipe of indoor heat exchanger is lower than the first temperature (A) or is the same as the first temperature (A), in order to make the surface temperature of indoor heat exchanger rise, the indoor air blower at work is driven according to the set air-quantity mode. It is then undertaken the icing preventing phase for preventing the surface of indoor heat exchanger from icing. Operating / stopping the compressor is not needed to furthest prevent indoor heat exchanger from icing.

Description

technical field [0001] The present invention relates to a control method of an air conditioner for suppressing icing of indoor heat exchangers, and more specifically, relates to suppressing the air from icing in indoor heat exchangers by using an indoor blower while suppressing the operation / stopping of compressors to the greatest extent. Regulator control method. Background technique [0002] Generally speaking, the split type air conditioner is composed of an indoor unit and an outdoor unit. An indoor fan and an indoor heat exchanger are installed on the indoor unit, and a compressor, an outdoor heat exchanger, an expansion valve, a square valve and an outdoor fan are installed on the outdoor unit. The indoor unit and the outdoor unit are connected by pipes through which the refrigerant flows. [0003] Therefore, the air conditioner performs cooling operation or heating operation according to the circulation direction of the refrigerant. During the heating operation, the ...
