Air conditioner and liquid inlet and flow equalizing device thereof

Abstract

The invention discloses a liquid inlet and flow equalizing device. The liquid inlet and flow equalizing device comprises a flow divider and a liquid inlet pipe, wherein the outlet of the liquid inlet pipe is communicated with the flow divider, the liquid inlet pipe comprises a first elbow and a second elbow, the first elbow and the second elbow are symmetrically arranged, the two ends of the first elbow are communicated with the two ends of the second elbow respectively, and the flow path of fluid flowing in through the inlet of the liquid inlet pipe and flowing through the first elbow to arrive at the outlet of the liquid inlet pipe is equal to the flow path of fluid flowing through the second elbow to arrive at the outlet of the liquid inlet pipe. After gas-liquid mixed refrigerant enters the liquid inlet pipe, one part of the refrigerant flows along the first elbow, the other part of the refrigerant flows along the second elbow, and finally the two parts of gas-liquid mixed refrigerant converge at the outlet of the liquid inlet pipe. Due to the fact that the two parts of gas-liquid mixed refrigerant are opposite in direction at the outlet of the liquid inlet pipe, steady flow is formed by the two parts of gas-liquid mixed refrigerant at the outlet of the liquid inlet pipe, the two parts of gas-liquid mixed refrigerant are evenly mixed and enter the flow divider so that the amounts of liquid refrigerant entering coil pipes are equal, and stability and reliability of the air conditioner are improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, and more specifically, to an air conditioner and a liquid inlet equalizing device thereof. Background technique [0002] The liquid inlet flow equalization device of the air conditioner is an essential device, which takes on the important role of fully mixing the gas-liquid two-phase refrigerant and evenly distributing it to each coil. The liquid inlet equalizing device in the prior art includes a flow divider 01 and a liquid inlet pipe 02 , wherein the outlet of the liquid inlet pipe 02 communicates with the inlet of the flow divider 01 . Such as figure 1 As shown, in order to meet the assembly of the air conditioner and the equal flow of the inlet liquid, the inlet pipe 02 needs to be arranged horizontally, and the diverter 01 needs to be arranged vertically, so that the vicinity of the connection end of the inlet pipe 02 and the diverter 01 needs to be bent. In this way, when the ga...
