The invention relates to intelligent defrosting method and system based on a room heat load, and an air conditioner. The method comprises the steps of detecting the temperature of an indoor environment under a heating mode; judging whether the temperature of the indoor environment meets a first preset defrosting condition; if yes, entering a first defrosting mode; and if not, determining the defrosting mode through judging the temperature rise range of the temperature of the indoor environment. According to the technical scheme provided by the invention, the appropriate defrosting mode is selected based on the room heat load state, so that the influence of the reduction of the room temperature is reduced.
Description
technical field [0001] The invention belongs to the field of air conditioner control, in particular to an intelligent defrosting method and system based on room heat load and an air conditioner. Background technique [0002] The air conditioner is a device capable of cooling / heating the room. When the air conditioner is running for heating, if the surface temperature of the outdoor heat exchanger, that is, the temperature of the outer pipe, is lower than the dew point temperature of the air and lower than the freezing point temperature, the surface of the heat exchanger will freeze. Frost, and the frost layer will reduce the heating performance of the air conditioner system, and even damage the air conditioner equipment, so it must be defrosted in time. [0003] At present, the heating and defrosting control methods of air conditioners are all using heating to cooling and using hot air to defrost. They do not consider the heat load state of the room. The defrosting process i...
