Description

Technical Field

[0001] This utility model belongs to the field of air conditioning equipment technology, and in particular relates to the structure of an air conditioning liquid separator assembly. Background Technology

[0002] Liquid separators are common structures in air conditioning systems, primarily used before the refrigerant enters the heat exchanger to ensure uniform refrigerant distribution and heat exchange. A liquid separator typically includes an inlet pipe and several outlet pipes. After entering the separator, the refrigerant is guided to the outlet pipes through the inlet pipe, thus achieving distribution. The separation effect of the liquid separator directly affects the performance of the heat exchanger, and consequently, the energy efficiency of the refrigeration equipment. Therefore, improving the separation effect of liquid separators is a problem that urgently needs to be solved by professionals in the field. Utility Model Content

First, the gas-liquid two-phase refrigerant is fully mixed through a gas-liquid mixing pipe. The mixed gas-liquid two-phase refrigerant enters the distribution chamber. The gas-liquid two-phase refrigerant in the distribution chamber is separated by a distributor. After the gas-liquid two-phase refrigerant is evenly mixed or fully mixed, it is evenly distributed to each distribution branch.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

Detailed Implementation

[0024] Example 1

[0025] like Figures 1 to 2 The diagram shows the structure of an air conditioning refrigerant distribution assembly according to this invention. It includes a gas-liquid mixing pipe 1, a distributor 2, and a distribution pipe 3. The gas-liquid mixing pipe 1 contains a torsion plate 9 extending spirally along the axial direction. Gas-phase refrigerant and liquid-phase refrigerant enter the gas-liquid mixing pipe 1. The torsion plate 9 repeatedly divides, moves, and merges the gas-liquid and liquid-phase refrigerant, thereby achieving gas-liquid mixing and increasing the refrigerant mixing degree. One end of the gas-liquid mixing pipe 1 is connected to the distributor 2, and the other end of the distributor 2 is connected to the distribution pipe 3. The distributor 2 has a distribution chamber 4, and the distribution pipe 3 communicates with the distribution chamber 4. First, the gas-liquid two-phase refrigerant is fully mixed through the gas-liquid mixing pipe 1. The mixed gas-liquid two-phase refrigerant then enters the distribution chamber 4. The distributor 2 separates the gas-liquid two-phase refrigerant in the distribution chamber 4. After uniform or sufficient mixing, the gas-liquid two-phase refrigerant is evenly distributed to each distribution branch.

[0026] The distributor 2 includes a diffuser section 6 and a distribution section 5. The diffuser section 6 is connected to the gas-liquid mixing pipe 1, and the distribution section 5 is connected to the diffuser section 6. The distribution chamber 4 is located between the diffuser section 6 and the distribution section 5. The distribution section 5 uniformly distributes the gas-liquid two-phase refrigerant in the distribution chamber 4. The distribution section 5 is provided with at least two distribution ports 7, which are connected to the distribution chamber 4. The distribution pipe 3 is installed in the distribution port 7 and welded and fixedly connected to the distribution port 7. The end of the distribution section 5 near the distribution chamber 4 is provided with a flow-guiding slope 8. The gas-liquid two-phase refrigerant in the distribution chamber 4 is uniformly distributed to the greatest extent through the distribution section 5, and the distributed gas-liquid two-phase refrigerant is guided into the distribution port 7 through the flow-guiding slope 8 and finally flows out through the distribution pipe 3.

[0027] In this embodiment, the liquid distribution ports 7 are uniformly arranged along the axial direction of the distribution section 5. The specific number can be set according to the actual use. The liquid distribution ports 7 are circular, and the inner diameter of the liquid distribution port 7 is 1 to 40% of the inner diameter of the gas-liquid mixing pipe 1. This design uses the principle of pressure difference to ensure the uniformity of the gas-liquid two-phase refrigerant distribution by each liquid distribution port 7.

[0028] In this embodiment, multiple twisting plates 9 are provided, and a mixing space 12 is formed between each pair of adjacent twisting plates 9, thereby realizing multiple division, movement and merging of the gas-liquid two-phase refrigerant, ensuring the uniformity of the mixing of gas-phase refrigerant and liquid-phase refrigerant. The twisting plates 9 can be made of stainless steel, copper, copper alloy, or carbon steel to avoid corrosion and extend service life.

[0029] This invention features a spirally extending torsion plate 9 inside the gas-liquid mixing tube 1. After the gaseous and liquid refrigerants enter the gas-liquid mixing tube 1, they are fully mixed by the torsion plate 9. The mixed gas-liquid two-phase refrigerant then enters the liquid distribution chamber 4. A flow guide slope 8 is provided inside the liquid distributor 2 to better disperse the gas-liquid two-phase refrigerant. The dispersed gas-liquid two-phase refrigerant is then distributed to each liquid distribution tube 3 through the liquid distribution port 7.

[0030] The diffuser section 6 is provided with a positioning step 10 at one end connected to the gas-liquid mixing pipe 1. One end of the gas-liquid mixing pipe 1 is inserted into the positioning step 10 and welded and fixed to the separator 2, thereby increasing the connection strength between the separator 2 and the gas-liquid mixing pipe 1.

[0031] One end of the gas-liquid mixing pipe 1 is provided with a flared part 11, which facilitates the connection of the gas-liquid mixing pipe 1 with an external pipe. When connecting, the external pipe can be inserted into the flared part 11 and fixed by welding.

[0032] Example 2

[0033] like Figure 3 As shown, based on the structure of Embodiment 1, Embodiment 2 makes another design to the gas-liquid mixing pipe 1. One end of the gas-liquid mixing pipe 1 is provided with a constriction section 13, and the end of the gas-liquid mixing pipe 1 is set to a constricted state to facilitate the connection of the gas-liquid mixing pipe 1 with an external pipeline.

[0034] Example 3

[0035] like Figure 4 As shown, based on the structure of Embodiment 1, Embodiment 3 makes another design to the gas-liquid mixing pipe 1. The gas-liquid mixing pipe 1 is a straight pipe, which makes the connection between the gas-liquid mixing pipe 1 and the external pipeline flexible and increases its applicability.
