Description

Technical Field

[0001] The utility model relates to the field of compressors, in particular to a low-temperature and high-efficiency liquid film compressor. Background Art

[0002] When the air conditioner is working, the compressor compresses the refrigerant into a high-pressure gas and then sends it to the condenser. In the condenser, the high-pressure gas releases heat and cools into a high-pressure liquid. After the high-pressure liquid is decompressed by the expansion valve, it flows into the evaporator. In the evaporator, the high-pressure liquid evaporates into a low-pressure gas, absorbing the heat in the air, thus making the air cooler. Finally, the low-pressure gas enters the compressor cycle again, forming a continuous refrigeration cycle. In this way, the air conditioning system can continuously circulate the refrigerant, thereby keeping the indoor air cool.

[0003] When the existing air-conditioning compressor is working, its refrigerant pipe directly exchanges heat with the refrigerant, which causes the temperature of the refrigerant pipe to be relatively high, thereby reducing the cooling efficiency of the refrigerant. Therefore, it is necessary to improve it. Summary of the invention

[0004] The utility model aims to provide a low-temperature and high-efficiency liquid film compressor, which solves the problem that when the existing air-conditioning compressor is working, its refrigerant pipe directly exchanges heat with the refrigerant, resulting in a relatively high temperature of the refrigerant pipe, which in turn reduces the cooling efficiency of the refrigerant.

[0006] Preferably, a flow guide cover is fixedly connected to the inner upper part of the hollow shell, and the flow guide cover is made of stainless steel. Through the setting of the flow guide cover, the condensed water sprayed to the surroundings can be guided to the refrigerant pipe.

[0007] Preferably, a water collecting trough is fixedly connected to the inner lower part of the hollow shell, and a drain pipe is fixedly connected to the bottom of the water collecting trough. Through the setting of the water collecting trough, the condensed water after use can be collected and then discharged uniformly.

[0008] Preferably, a fixing rod is fixedly connected to the outer side of the sealing sleeve, and the other end of the fixing rod is fixedly connected to the inner surface of the hollow shell. The setting of the fixing rod has a fixing effect on the sealing sleeve.

[0009] Preferably, the hollow disk is I-shaped and made of stainless steel. The condensed water can rotate one circle in the hollow disk without being blocked.

[0010] Preferably, the refrigerant pipe is spiral-shaped and made of copper. The copper refrigerant pipe has high heat exchange efficiency, and the spiral design can increase the travel of the refrigerant.

[0011] Preferably, there are multiple nozzles, and the multiple nozzles are evenly distributed at the bottom of the hollow disk. Through the arrangement of the nozzles, condensed water can be discharged from the hollow disk.

[0013] 1. The utility model arranges a hollow shell on the outside of the refrigerant pipe of the compressor, and then arranges a hollow disk in the hollow shell, and a nozzle is arranged at the bottom of the hollow disk. In addition, the condensed water discharged from the indoor unit of the air conditioner can be connected to the condensed water return pipe, and then the condensed water enters the hollow disk and is sprayed on the refrigerant pipe. The condensed water will form a liquid film on the surface of the refrigerant pipe, so as to fully utilize the low temperature carried by the condensed water to cool the refrigerant in the refrigerant pipe. In this way, the energy consumption of the air conditioner can be reduced and the utilization rate of the condensed water can be improved.

[0014] 2. The utility model arranges an electric motor above the hollow shell, and the electric motor can drive the hollow disk to rotate, so that the condensed water can be evenly sprayed on the refrigerant pipe, thereby improving the utilization rate of the low temperature carried by the condensed water.
