Abstract

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, and in particular relates to an intelligent defrosting method, system and air conditioner based on room heat load. Background technique [0002] The air conditioner is a device that can cool / heat the room. When the air conditioner is running, if the surface temperature of the outdoor heat exchanger, that is, the temperature of the outer tube is lower than the air dew point temperature and lower than the freezing point temperature, the surface of the heat exchanger will freeze. 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 control method of air conditioning heating and defrosting is to use heating to refrigeration and use hot gas to defrost, and the heat load state of the room is not considered. The defrosting process itself will cause the room temperature to ...
