Abstract

The invention belongs to the field of air conditioners and aims to solve the problem that proper defrosting modes cannot be started when defrosting is needed through existing air conditioner defrosting control methods. In order to solve the problem, the invention provides an air conditioner and a defrosting control method thereof. The method comprises the following steps that a universal set comprising all working conditions of the air conditioner is obtained; the universal set is divided into a first zone, a second zone and third zone through a first demarcation and a second demarcation, and the first demarcation and the second demarcation are both curves; when the air conditioner is in a heating working condition, the current working condition of the air conditioner is obtained; when the current working condition is in the first zone, the air conditioner is kept in the heating working condition; when the current working condition is in the second zone, the air conditioner is made to start a first defrosting mode; and when the current working condition is in the third zone, the air conditioner is made to start a second defrosting mode. According to the technical scheme, the universal set comprising all the working conditions of the air conditioner is partitioned through the first demarcation and the second demarcation, and 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...
