Embodiment

[0031] The process of comparing the dispensing effect of the liquid dispenser head a of the prior art with the liquid dispenser head b of the present application is as follows:

[0032] A liquid inlet pipe 5 with a 90° bend is connected to the liquid inlet 3 of the liquid dispenser head a and the liquid dispenser head b, wherein the apex of the split tip 2 of the liquid dispenser head 2 is moved away from the liquid inlet The direction of the liquid inlet direction of the tube 5 deviates by 0.7mm;

[0033] Keep the size of other parts, grid topology parameters and calculation process on the liquid head a and liquid head b completely consistent;

[0034] And set the inlet parameters of dispenser head a and dispenser head b as follows:

[0035] The dryness of the refrigerant inlet is 0.2; the inlet pressure is 1.15MPa; the inlet flow is 0.0528kg / s;

[0036] Finally, the results of Table 1 and Table 2 are obtained

[0037] Table 1 Distribution of refrigerant flow rate in each ...

Abstract

The invention provides a liquid distributing mechanism with uniform liquid dispensing function, an installation method thereof, and an air conditioning system. The liquid distributing mechanism includes a cylindrical body and a splitting cone. A liquid distributing cavity is formed in the cylindrical body, and the splitting cone is arranged in the liquid distributing cavity. The axis of the cylindrical body has a pitch. The liquid separation mechanism with uniform liquid separation function, its installation method, and the air-conditioning system provided by the present invention set the distance between the apex of the diversion cone and the axis of the cylindrical body, so that the apex of the diversion cone points to the liquid phase concentration part, thereby The liquid-phase refrigerant can evenly enter the distribution hole under the diversion of the apex and the liquid distribution surface, which overcomes the problem of the large difference in the dryness of the refrigerant in the distribution hole caused by the uneven distribution of the liquid in the prior art, and achieves The purpose of uniform liquid distribution.

Description

technical field [0001] The invention relates to the technical field of fluid distributing devices, in particular to a liquid distributing mechanism with a uniform liquid dispensing function, an installation method thereof, and an air conditioning system. Background technique [0002] As an important part of the air-conditioning heat exchange system, the liquid distribution head, together with the capillary tube, is responsible for the distribution of the refrigerant flow in each branch before the system enters the heat exchanger. Whether the refrigerant flow distribution of each branch of the heat exchanger can be well matched with the wind speed distribution on the surface of the heat exchanger directly affects the heat transfer capacity of the air conditioning system; the conventional Venturi liquid separator design is usually based on the axisymmetric structure combination The principle of uniform liquid distribution is designed to pursue the maximum uniformity of liquid ...
