Abstract

The invention belongs to the field of air conditioners and provides an air conditioner and a defrosting control method thereof. The air conditioner and the defrosting control method thereof aim at solving the problem that by means of existing air conditioner defrosting control methods, the proper defrosting mode cannot be obtained at the moment when defrosting is needed. The method comprises the following steps of obtaining a universal set containing all operation conditions of the air conditioner; dividing the universal set into a first area, a second area and a third area through a first demarcation line and a second demarcation line, wherein the first demarcation line and the second demarcation line are both broken lines; under the circumstance that the air conditioner is in the current heating working condition, obtaining the current working condition of the air conditioner; under the circumstance that the current working condition is in the first area, making the air conditioner maintain in the heating working condition; under the circumstance that the current working condition is in the second area, making the air conditioner enter a first defrosting mode; and under the circumstance that the current working condition is in the third area, making the air conditioner enter a second defrosting mode. According to the air conditioner and the defrosting control method thereof, the universal set containing all the working conditions of the air conditioner is demarcated through the first demarcation line and the second demarcation line, so that the defrosting control mechanism is optimized.

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...
