Abstract

The invention belongs to the field of air conditioners, in particular, relates to an air conditioner and a defrosting control method thereof, and solves the problem of incapability of obtaining a proper defrosting mode at the defrosting time in a traditional air conditioner defrosting control method. For the purpose, the air conditioner defrosting control method, provided by the invention, mainly comprises the following steps: the operation time length of previous defrosting, the heating operation time length of the air conditioner after defrosting and the frequency of a compressor are obtained; and under the conditions of satisfying a judging condition 1, a judging condition 2 and a judging condition 3, the air conditioner is in a first defrosting mode. The defrosting control method optimizes the defrosting control mechanism of the air conditioner according to the defrosting time and the defrosting mode of the air conditioner determined by the judging conditions (1, 2, 3).

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner and a defrosting control method thereof. Background technique [0002] An air conditioner (such as a household air conditioner) is a device that can adjust the indoor ambient temperature. Its working principle is: through the high-pressure / low-pressure / gas / liquid state conversion of the refrigerant between the circulation lines, the indoor ambient temperature can be adjusted. Lowering or raising, that is, from the perspective of the indoor unit of the air conditioner, the air conditioner is in a cooling or heating cycle. When the air conditioner is running in the heating cycle, the outdoor unit of the air conditioner acts as an evaporator (the low-pressure liquid refrigerant becomes a low-pressure gas after absorbing heat and evaporating in the evaporator), and the indoor unit of the air conditioner acts as a condenser. When the evaporating temperature is lower...
