Embodiment Construction

[0039] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0040] The air conditioner defrosting device, the air conditioner defrosting control system, the air conditioner defrosting control method and the air conditioner of the present invention will be described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0041] Such as figure 1Shown is a schematic structural diagram of an air-conditioning defrosting device in Embodiment 1. In this embodiment, the outdoor heat exchanger unit 5 includes two outdoor heat exchangers, that is, a first outdoor heat exchanger 13 and a second outdoor heat exchanger 13. The heat exchanger 14, the gas outlet and the liquid inlet of the first outdoor heat exchanger 13 are respectively provided with ...

Abstract

The invention particularly relates to an air conditioner defrosting device, an air conditioner defrosting control method and a system and an air conditioner. Multiple parallel outdoor heat exchangers are provided; one or more outdoor heat exchangers can be selected for heating according to application environments of the air conditioner and user demands; when the outdoor heat exchangers need to defrost, the outdoor heat exchangers are defrosted by a hot air bypassing mode, and the other outdoor heat exchangers without needing defrosting are adopted to continuously heat, so that the indoor continuous heating in the defrosting process is realized, and the indoor comfort is prominently improved; and meanwhile, low-temperature gas after defrosting cooling in a bypass pipeline dose not directly enter a gas return port of a compressor, but enters a refrigerant circulating loop after being throttled by an electronic throttling part, so that the great change of the intake / exhaust pressure of the compressor cannot be caused, and the operation reliability of the compressor is improved.

Description

technical field [0001] The invention relates to the field of air conditioner control, in particular to an air conditioner defrost device, an air conditioner defrost control method, a system and an air conditioner. Background technique [0002] At present, the defrosting method used by most air conditioners is four-way valve reversing defrosting. During the defrosting period, due to the reversing of the four-way valve, the indoor fan stops supplying air, causing the indoor temperature to drop and reducing indoor comfort. The traditional hot gas bypass defrosting technology directly bypasses part of the high-temperature and high-pressure steam into the outdoor heat exchanger for defrosting, and then directly enters the return air port of the compressor, which will cause a large change in the suction and discharge pressure of the compressor. Poor, and will reduce the indoor user experience. How to avoid frosting or how not to affect the supply of indoor heat under the conditio...
