Abstract

The invention discloses an air conditioner defrosting control method and a device thereof. The air conditioner defrosting control method comprises the following steps of: entering a defrosting mode, and detecting continuous defrosting times for reaching a maximum defrosting time; setting a maximum defrosting time of the present defrosting operation according to the continuous defrosting times forreaching the maximum defrosting time and an initial maximum defrosting time; recording the defrosting time of this defrosting; when the defrosting time of this defrosting reaches the maximum defrosting time of the present defrosting operation, renewing the continuous defrosting time for reaching the maximum defrosting time; setting the maximum defrosting time for the next defrosting operation, based on the renewed continuous defrosting time for reaching the maximum defrosting time and the initial maximum defrosting time. The air conditioner defrosting control method and device according to theembodiment of the invention can self-adaptively adjust the maximum defrosting time without affecting user using, prevent the accumulation of the frost layer, and avoid the risk of pipe explosion.

Description

technical field [0001] The invention relates to the technical field of air conditioners, and in particular, to a defrosting control method and a device thereof for an air conditioner. Background technique [0002] Multi-line central air conditioners have been widely used in small and medium-sized buildings and some public buildings. With the diversity of working conditions, the personalized needs of users are becoming more and more complex, and the requirements for the reliability of multi-line central air conditioners are also getting higher and higher. During the heating operation 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, frost formation may also present dangerous hidden dangers such as copper pipe bursting. At present, the air conditioning system has increased the l...
