Abstract

The invention belongs to the technical field of air conditioners, and particularly relates to an air conditioner defrosting control method. In order to improve the air conditioner defrosting efficiency, the method is provided and comprises the following steps that after an air conditioner is in the defrosting mode, an outdoor fan is controlled to stop rotating; and after the rotating stopping timeof the outdoor fan is longer than the set time, the outdoor fan is controlled to continuously rotate reversely. According to the technical scheme, part of frost on an outdoor coiled pipe is melted within the set time period, at the moment, the outdoor fan is controlled to continuously rotate reversely, a frost layer in an outdoor unit in the frost melting process is blown off more easily and quickly through the reverse blowing effect of the outdoor fan, and accordingly, the defrosting efficiency is improved. Compared with a traditional defrosting mode, namely, the condition that the frost layer needs to wait to be gradually separated from the outdoor unit or is completely melted into water, through the air conditioner defrosting control method, defrosting operation can be completely morequickly, and the influence on the indoor temperature in the defrosting process is effectively reduced.

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...
