Description

Technical Field

[0001] The present invention relates to the field of refrigeration equipment, and particularly to a fluorine pump type full liquid evaporation coil. Background Art

[0002] A refrigeration system generally includes a compressor, a condenser and an evaporator. The existing evaporation coil receives high-pressure refrigerant from the compressor. The high-pressure refrigerant evaporates and absorbs heat in the evaporator and then turns into gas and enters the condenser for condensation. The refrigerant then returns to the compressor to be compressed. The problem with the existing evaporator is that when the refrigerant evaporates, the gaseous refrigerant will carry away part of the liquid refrigerant to the condenser. This part of the liquid refrigerant does not fully exchange heat with the outside world in the evaporator, resulting in insufficient refrigeration efficiency. Summary of the Invention

[0003] To solve the above technical problems, the purpose of the present invention is to provide a fluorine pump type full liquid evaporation coil with high heat exchange efficiency.

[0004] The technical solution adopted by the present invention to solve the problem is: a fluorine pump type full liquid evaporation coil, including: a throttle valve, a fluorine pump, an evaporation coil, a first inlet pipeline, a second inlet pipeline, an outlet pipeline, a first return pipeline, and a second return pipeline; the first inlet pipeline and the second inlet pipeline are both used to receive high-pressure refrigerant; the first inlet pipeline is connected to the top of the evaporation coil, the second inlet pipeline is connected to the fluorine pump, and the throttle valve is arranged on the second inlet pipeline. The first return pipeline connects the top of the evaporation coil and the fluorine pump, and the second return pipeline connects the fluorine pump and the bottom of the evaporation coil; the outlet pipeline is connected to the top of the evaporation coil.

[0005] As a preferred technical solution, it further includes a capillary tube, and the capillary tube is arranged on the first inlet pipeline.

[0006] As a preferred technical solution, the first inlet pipeline and the outlet pipeline are respectively connected to the left and right ends of the evaporation coil.

[0007] As a preferred technical solution, the first inlet pipeline and the second inlet pipeline are connected to a compressor through a tee, and the outlet pipeline is connected to a condenser.

[0008] The beneficial effect of the present invention is that the low-temperature gaseous refrigerant coming out of the throttle valve and the liquid refrigerant that has not evaporated at the top of the evaporation coil are pushed back to the bottom of the evaporation coil by the fluorine pump. This part of the pushed-back refrigerant is used for heat exchange in the evaporation coil. Among them, the liquid refrigerant that has not evaporated at the top of the evaporation coil is reused, effectively improving the efficiency of the evaporation coil. Description of the Drawings

[0015] Referring to Figure 1 , a fluorine pump type full liquid evaporation coil, comprising: a throttle valve 1, a fluorine pump 2, an evaporation coil 3, a first inlet pipeline 5, a second inlet pipeline 6, an outlet pipeline 7, a first return pipeline 8, and a second return pipeline 9; both the first inlet pipeline 5 and the second inlet pipeline 6 are used to receive high-pressure refrigerant; the first inlet pipeline 5 is connected to the top of the evaporation coil 3, the second inlet pipeline 6 is connected to the fluorine pump 2, and the throttle valve 1 is arranged on the second inlet pipeline 6, the first return pipeline 8 is connected to the top of the evaporation coil 3 and the fluorine pump 2, the second return pipeline 9 is connected to the fluorine pump 2 and the bottom of the evaporation coil 3; the outlet pipeline 7 is connected to the top of the evaporation coil 3.

[0016] The principle of the present invention is as follows:

[0017] The high-pressure liquid refrigerant in the first inlet pipeline 5 enters the evaporation coil 3. The high-pressure liquid refrigerant in the second inlet pipeline 6 directly reaches the throttle valve 1, forms a low-pressure high-speed gas at the throttle orifice, becomes the driving force of the fluorine pump 2, and enables the fluorine pump 2 to generate negative pressure. The fluorine pump 2 pushes the refrigerant in the evaporation coil 3 to flow from the bottom to the top. The low-pressure refrigerant evaporates above, and the gas part is discharged through the outlet pipeline 7. The low-temperature gas refrigerant coming out of the throttle valve 1 and the liquid refrigerant that has not evaporated at the top of the evaporation coil 3 are pushed back to the bottom of the evaporation coil 3 by the fluorine pump 2. This part of the pushed-back refrigerant is used for heat exchange in the evaporation coil 3. Among them, the liquid refrigerant that has not evaporated at the top of the evaporation coil 3 is reused, and has a heat exchange effect superior to that of the dry evaporation coil 3.

[0018] As a preferred embodiment, a capillary tube 4 is further included, and the capillary tube 4 is arranged on the first inlet pipeline 5.

[0019] As a preferred embodiment, the first inlet pipeline 5 and the outlet pipeline 7 are respectively connected to the left and right ends of the evaporation coil 3.

[0020] As a preferred embodiment, the first inlet pipeline 5 and the second inlet pipeline 6 are connected to a compressor through a tee, and the outlet pipeline 7 communicates with a condenser.

[0021] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural transformations made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
