Abstract

The invention discloses an air-conditioning defrosting control method and its device, wherein the air-conditioning defrosting control method includes: entering the defrosting mode, and detecting the number of continuous defrosting times that reach the maximum frosting time; Defrost times and initial maximum frost time, set the maximum defrost time of this defrost; record the defrost time of this defrost; when the defrost time of this defrost reaches the maximum frost time of this defrost , then update the number of consecutive defrosting times to reach the maximum frosting time; based on the updated number of consecutive defrosting times to reach the maximum frosting time and the initial maximum frosting time, set the maximum frosting time for the next defrosting. The air conditioner defrosting control method and device of the embodiments of the present invention can adaptively adjust and maximize the frosting time without affecting the user's use, prevent the accumulation of frosting layers, and avoid the risk of pipe bursting.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner defrosting control method and device thereof. Background technique [0002] Multi-connected central air conditioners have been widely used in small and medium-sized buildings and some public buildings. With the diversity of working conditions, the individual needs of users are becoming more and more complex, and the requirements for the reliability of multi-connected central air conditioners are also getting higher and higher. During heating work in winter, the surface temperature of the external heat exchanger will reach below zero, and frost may occur. The frost layer will block the air flow, affect the heating capacity of the air conditioner, and lead to poor user experience. In addition, there may be dangerous hidden dangers such as copper tube bursting due to frosting. At present, the air conditioning system has increased the limit of the maximu...
