Abstract

The invention relates to the field of a refrigeration air conditioner of a steam compressor, in particular to an air conditioner outdoor unit, an air conditioner outdoor unit defrosting judging system and an air conditioner outdoor unit defrosting judging method. According to the air conditioner outdoor unit, the air conditioner outdoor unit defrosting judging system and the air conditioner outdoor unit defrosting judging method, disclosed by the invention, the air conditioner outdoor unit is internally and additionally provided with an anemograph which is used for detecting the air speed of an air outlet, whether an outdoor air-cooled heat exchanger is frosted or not can be judged by the air conditioner outdoor unit defrosting judging system by combining the changing situation of the air speed and the tube temperature of the outdoor air-cooled heat exchanger, defrosting can be carried out by controlling the state of a defrosting switch, the accuracy of judging the defrosting by the system is increased, the purposes that the defrosting can be carried out when frost exists and the defrosting cannot be carried out when no frost exists can be achieved, the defrosting period can be prolonged to the maximum, the influence on indoor air temperature by an air conditioner defrosting process can be reduced, and the using comfort of a user and the heating effect of the air conditioner are increased.

Description

Technical field [0001] The invention relates to the field of vapor compressor refrigeration and air conditioning, and in particular to a defrosting determination system and method for an outdoor unit of an air conditioner and an outdoor unit of an air conditioner. Background technique [0002] The compression refrigeration system of general air conditioners is composed of compressors, condensers, evaporators and throttling elements. The pipelines are connected in a certain order to form a closed system. The closed system is filled with an appropriate amount of refrigerant and plays a role in the compressor. When the refrigerant comes out of the compressor, it returns to the compressor through the condenser, evaporator and throttling structure. The heat is moved along with the movement of the refrigerant, realizing the refrigeration process from the evaporator to the condenser. . [0003] When the air conditioning system is heating, the system sends heat from the outside to the roo...
