Embodiment Construction

[0018] 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.

[0019] The defrosting control method of the present invention is mainly aimed at an air conditioner with a bypass defrosting circuit. Those skilled in the art can understand that the bypass defrosting circuit of the air conditioner is set between the compressor of the air conditioner and the outdoor unit, and is used to introduce the high-pressure gas discharged from the compressor into the o...

Abstract

The invention belongs to the technical field of air conditioners, and particularly relates to a defrosting control method of an air conditioner. In order to improve the defrosting efficiency of the air conditioner, the provided defrosting control method of the air conditioner is proposed for the air conditioner with a bypass defrosting circuit, the method includes the following steps that when theair conditioner enters into a defrosting mode for the n time, heating operation time t<n> of the air conditioner is obtained; if the t<n> is greater than first set time, the air conditioner enters into a reverse cycle defrosting mode, and otherwise, the air conditioner enters into a bypass defrosting mode; and if the air conditioner enters into the reverse cycle defrosting mode when the air conditioner enters into the defrosting mode for the n time, the air conditioner enters the bypass defrosting mode when the air conditioner enters into the defrosting mode for the (n+1) time andthe (n+2) time, wherein n is equal to 3m+1, and m is an integer greater than or equal to 0. According to the defrosting control method, the best defrosting mode can be accurately selected, an outdoor fan can further be controlled to reverse at intervals, and a frost layer is blown down rapidly by using the blowback effect of the outdoor fan to improve the defrosting efficiency.

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...
