Patent ID: 11009283

Abstract:
A system and a method for defrosting/de-icing an air-conditioner are provided, the system comprising: a 3D depth sensor disposed inside an air-conditioner outdoor unit casing, for acquiring information regarding outer diameters of pipes of an outdoor heat exchanger, distances between the pipes, and distances between the respective pipes and an air-conditioner outdoor unit casing side plate; and a controller connected to the 3D depth sensor, for receiving the information acquired by the 3D depth sensor and controlling the air conditioner to enter or exit a defrosting-deicing mode. The system and method for defrosting/de-icing an air-conditioner provided by the present disclosure can effectively and timely perform defrost/de-ice operation on the outdoor heat exchanger to prevent freezing; besides, it can prevent the impact on the air-conditioner's heating function to the utmost extent so as to significantly improve user experience.
