Embodiment Construction

[0015] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, components and circuits have not been described in detail so as not to obscure the present invention.

[0016] Such as figure 1 As shown, a defrosting method of an air-conditioning unit is disclosed, comprising:

[0017] S11. Detect various influencing factors affecting the defrosting operation of the outdoor unit, and perform at least one defrosting judgment according to the various influencing factors;

[0018] Wherein, the at least one defrosting judgment includes: judging based on the magnitude relationship between the degree of frosting of the outdoor unit and a preset degree threshold, and / or based on the distance between the outdo...

Abstract

A defrosting method for an air conditioning unit comprises steps as follows: various influence factors affecting defrosting operations of an outdoor unit are detected, and defrosting judgment is performed at least once according to the various influence factors as follows: judgment is performed according to the magnitude relation of the frosting degree of the outdoor unit and a preset degree threshold value, and / or judgment is performed according to the magnitude relation of the defrosting interval between the current time and the previous defrosting time of the outdoor unit and a preset interval threshold value; according to judgment results, whether the outdoor unit performs the defrosting operations is determined. According to the method and the device, defrosting judgment is performed by the aid of the frosting degree and the defrosting interval, the device is suitable for various regions with different environments, and the defrosting effect is guaranteed; and in addition, on the basis that the defrosting effect is guaranteed, defrosting times can be effectively reduced, and the advantage of energy saving can be realized.

Description

technical field [0001] The invention relates to the technical field of air-conditioning equipment, in particular to a defrosting method and device for an air-conditioning unit. Background technique [0002] At present, when the outdoor unit of the air conditioner is heating in winter, frost is generally formed, but the situation of frost formation is different due to the different ambient temperature and humidity of the outside world. But as an air conditioner, it is only based on the ambient temperature and the running time to determine whether it can enter the defrosting. For places with high humidity and places with low humidity, the defrosting conditions are the same. [0003] For example, in the middle and lower reaches of the Yangtze River, because of the low temperature and high humidity, it may take 30 minutes to defrost, but in the north, the relative humidity is low, and there is no need to defrost within 30 minutes. The conditions are the same, so 30 minutes in ...
