Embodiment Construction
[0038] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings. These embodiments are only used to illustrate the present invention, and are not intended to limit the protection scope of the present invention.
[0039] Such as figure 1 and figure 2 As shown, the present invention provides an air-conditioning defrosting and deicing system, which includes:
[0040] The 3D depth sensor 1 is arranged in the air conditioner external unit case 4, and is used to collect the outer diameter of the pipe of the outdoor heat exchanger 3, the distance between the pipes (L1) and the distance between the pipe and the side plate of the air conditioner external unit case 4. Distance (L2, L3) information;
[0041] The controller 2 connected with the 3D depth sensor 1 is used to receive the information collected by the 3D depth sensor 1 and control the air conditioner to enter or exit the defrosting and deicing mode;

The invention discloses an air conditioner frost and ice removing system and method. The system comprises a 3D depth sensor and a controller, wherein the 3D depth sensor is arranged in an air conditioner outdoor unit chassis, and is used fro acquiring outer diameters of pipes of an outdoor heat exchanger, distances between the pipes and distance information between the pipes and side plates of theair conditioner outdoor unit chassis; and the controller is connected with the 3D depth sensor, and is used for receiving the information acquired by the 3D depth sensor and controlling an air conditioner to enter or retreat from a frost and ice removing mode. The air conditioner frost and ice removing system and method can effectively and timely perform the frost and ice removing operation on the outdoor heat exchanger to prevent the icing condition, and meanwhile, can prevent influence on a heating function of the air conditioner to the greatest extent to prominently improve user experiences.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner defrosting and deicing system and method. Background technique [0002] At present, the air conditioners on the market have automatic defrosting function during heating operation in winter, which are generally divided into two types: time control and temperature control. [0003] When the outdoor temperature is relatively low (about 0°C) and the air humidity is high, the moisture content in the air is high, which is easy to adhere to the heat sink, and frost will form on the outdoor heat exchanger. If the defrosting is not complete, the frost will slowly form It will accumulate and cause freezing conditions. [0004] If time control is used to defrost, it usually takes 15-30 minutes. The air conditioner controls the operation program according to the time. If there is no defrosting within 15-30 minutes, it will turn to heating. Therefore, the longer t...
