The invention discloses a defrosting control method and device for an air conditioner. The method comprises the steps that when the air conditioner is in a heating running mode, the air conditioner runs for a preset time N1, the complete machine power W, the exhaust temperature T and the exhaust pressure P of the current air conditioner are collected to serve as first-group data, and the first-group data is stored; after the air conditioner continuously runs for a time deltaT, whether the running frequency of a compressor meets the defrosting starting condition or not is detected; after the running frequency of the compressor meets the defrosting starting condition, the complete machine power W, the exhaust temperature T and the exhaust pressure P of the current air conditioner are acquired to serve as second-group data, the second-group data is compared with the first-group data, and when a comparison value of the second-group data and the first-group data meets the defrosting condition, the air conditioner is defrosted according to a preset mode. According to the defrosting control method for the air conditioner, little output temperature fluctuation of the air conditioner is generated, and then the comfort of somatic sensation of a user is improved.
Description
technical field [0001] The invention relates to the technical field of air-conditioning equipment, in particular to a method for controlling defrosting of an air-conditioner and a control device thereof. Background technique [0002] When the air conditioner is in heating operation, due to the low temperature of the outdoor heat exchanger itself and the influence of the outdoor environment, a thick layer of frost will slowly accumulate on the outdoor heat exchanger. The most intuitive impact of frost is that the heat exchange capacity of the outdoor heat exchanger is greatly reduced, resulting in a decrease in the heating capacity of the air conditioner. Therefore, regular defrosting is required to maintain the heating capacity. At present, for the air conditioners produced by various manufacturers, there are roughly three ways to determine whether the air conditioner is controlled to enter defrosting. The first is to fix the time interval, which is more common in fixed freq...
