Embodiment Construction

[0019] In order to make the embodiments, technical solutions and advantages of the present invention more obvious, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Example. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention.

[0020] The defrosting control method of the air conditioner of the present invention is as follows: after the air conditioner enters the defrosting mode, the outdoor fan is controlled to continuously reverse. In the defrosting process of the prior art, the outdoor fan is usually in a stalled state, but the present invention controls the outdoor fan to continuously reverse after the air condit...

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 defrosting efficiency of an air conditioner, the method comprises the following step that after the air conditioner enters a defrosting mode, an outdoor fan is controlled to continuously reverse. According to the technical scheme, due to the reverse blowing effect of the outdoor fan, a frost layer in the defrosting process of an outdoor unit is easier and faster to blow off, so that the defrosting efficiency is improved. Compared with a traditional defrosting mode that the situation that the frost layer needs to be gradually separated from the outdoor unit or all melts into water is needed, the defrosting operation can be completed more quickly, and the influence of the defrosting process on the indoor temperature 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...
