Liquid distributor and air conditioner comprising same

Abstract

The invention provides a liquid distributor and an air conditioner comprising the liquid distributor. The liquid distributor comprises a liquid inlet part (1) arranged at the upper end, and a diversion part (2) positioned at the lower end, wherein a liquid inlet of the liquid inlet part (1) is provided with a flow homogenizing layer (11); and the flow homogenizing layer (11) is provided with circulating channels which are evenly distributed. According to the liquid distributor provided by the invention, the fluid entering into the liquid distributor can be evenly distributed, so that the flow velocity is reduced, and the heat exchange is more even; and furthermore, vapor-liquid phase separation is reduced, and the noise caused by the flow of the fluid can be lowered.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a liquid separator and an air conditioner containing the same. Background technique [0002] The liquid separator is also called a splitter, also known as a liquid distributor. It is an auxiliary device between the expansion valve and the evaporator in the refrigeration system. Its function is to distribute the refrigerant two-phase mixture from the expansion valve evenly and equally to each coil of the evaporator. [0003] Usually, the refrigerant entering the liquid separator needs to go through a contraction process in the liquid separator. During this process, it will be accompanied by pressure loss. After passing through this contraction section, the refrigerant will enter the liquid separator to diffuse chamber, and then shunted through the shunt pipe connected to the lower end of the diffusion chamber. During the contraction process, the pressure of the refrigerant will i...

AI Technical Summary

Problems solved by technology

During the contraction process, the pressure of the refrigerant will increase, the flow rate will also increase, and the energy loss will be large. The gas-liquid two-phase refrigerant from the expansion valve will flow into the diffusion chamber without sufficient uniform mixing. The refrigerant in the cavity, due to the sudden increase of the space, the flow rate and pressure will change suddenly, resulting in uneven distribution, reduced heat transfer, and increased energy consumption

At the inlet end of the liquid separator, due to the high-speed diversion and narrow space constraints, the gas-liquid two-phase fluid is easy to separate, and it is easy to generate liquid flow sound, breed noise, and affect the comfort of the environment.
