Abstract

The invention belongs to the technical field of air conditioners, and particularly relates to a defrosting control method of an air conditioner. The defrosting control method of the air conditioner isapplied to the air conditioner with double fans arranged on an outdoor unit so as to improve the defrosting efficiency of the air conditioner. The method includes the following steps that after the air conditioner enables the defrosting mode, an upper fan and a lower fan are controlled to stop rotation; after the first set time, only the upper fan is controlled to rotate reversely for the secondset time; after the first set time, the lower fan is controlled to rotate reversely for the second set time, and the upper fan is controlled to rotate reversely for the third set time; and after the second set time, only the lower fan is controlled to rotate reversely for the second set time. According to the method, the fans in the corresponding positions are controlled in a matched manner to rotate reversely according to the thawing sequence of frost, so that frost layers are blown off accurately, and the defrosting efficiency of the air conditioner is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner defrosting control method. Background technique [0002] As a device that can adjust the indoor ambient temperature, the air conditioner works on the principle that the indoor ambient temperature is reduced or increased by the refrigerant passing through the circulation pipeline through high-pressure / low-pressure / gas / liquid state transitions, that is, from From the perspective of the indoor unit, the air conditioner is in cooling or heating mode. When the air conditioner is in heating operation, if the temperature of the outdoor coil is too low under certain humidity conditions, it will cause frosting, and the frosting of the outdoor coil will reduce the heat exchange efficiency of the outdoor heat exchanger and affect the cooling performance of the air conditioner. The thermal effect reduces the comfort of the indoor environment and affec...
