Problems solved by technology

However, the gas-liquid separator cannot achieve 100% separation of the gas-liquid two-phase refrigerant. There must be a small amount of gas-phase refrigerant mixed in the liquid-phase refrigerant and enters the liquid separator. If this part of the gas-phase refrigerant cannot be mixed with the liquid-phase refrigerant The mixing of the liquid phase refrigerant will affect the flow state of the liquid phase refrigerant, resulting in uneven liquid distribution of the liquid phase refrigerant in the liquid distribution tube

Abstract

The invention provides a liquid separation device and an air conditioner comprising the liquid separation device. The liquid separation device comprises a gas-liquid separator, a liquid guide tube, a connecting tube, a gas-liquid mixing chamber, and a liquid separation tube, wherein the gas-liquid separator is provided with a first inlet, a first outlet and a second outlet; the liquid guide tube is communicated with the gas-liquid separator by the first outlet; the connecting tube is communicated with the gas-liquid separator by the second outlet; the gas-liquid mixing chamber is provided with a third inlet, a second inlet and a third outlet; the third inlet is communicated with the liquid guide tube; the second inlet is communicated with the connecting tube; and the liquid separation tube is communicated with the third outlet of the gas-liquid mixing chamber. With the adoption of the technical scheme, the gas-liquid mixing chamber is arranged between the liquid separation tube and the gas-liquid separator, so that gas and liquid phase refrigerants before entering the liquid separation tube can be uniformly mixed, distribution of the refrigerants in the liquid separation tube is improved, and liquid separation of the liquid separation tube can be more uniform.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a liquid distributing device and an air conditioner including the liquid dispensing device. Background technique [0002] At present, the mainstream of heat exchangers on air conditioner heat exchangers is still finned copper tube heat exchangers. Finned copper tube heat exchangers have problems such as high cost, poor resistance to electrical corrosion, and complicated welding of liquid distribution pipe / collection pipe components. [0003] The micro-channel heat exchanger adopts flat tube enhanced heat transfer technology. It is a flat tube heat exchanger made of all-aluminum material. It has the advantages of low cost, strong resistance to electrical corrosion, and simple structure of the liquid distribution pipe / collection pipe assembly. Moreover, microchannel heat exchangers have been used in single coolers and have been used in automotive air conditioners f...
