Liquid separation device and air conditioner including the liquid separation device

Abstract

The invention provides a liquid separating device and an air conditioner comprising the liquid separating device. The liquid separation device includes: a gas-liquid separator, which is provided with a first inlet, a first outlet, and a second outlet; a liquid introduction pipe, which communicates with the gas-liquid separator through the first outlet; and a connecting pipe, which is separated from the gas-liquid through 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 connected with the liquid introduction pipe, and the second inlet is connected with the connecting pipe; and the liquid distribution pipe is connected with the gas-liquid mixing chamber. The third exit connects. Applying the technical scheme of the present invention, by setting a gas-liquid mixing chamber between the liquid separation pipe and the gas-liquid separator, the gas-liquid two-phase refrigerant before entering the liquid separation pipe is uniformly mixed, the distribution of the refrigerant in the liquid separation pipe is improved, and the Dispensing tube dispenses liquid more evenly.

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...

AI Technical Summary

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
