Description

Technical Field

[0001] The utility model relates to a refrigerant pipeline connection structure and belongs to the technical field of refrigerant pipes. Background Art

[0002] In the air-conditioning system, the refrigerant flows through the pipeline connecting the heat exchanger, valves, compressors and other major refrigeration components. The air-conditioning refrigerant pipe refers to the pipeline connecting the heat exchanger, valves, compressors and other major refrigeration components in the air-conditioning system. The air-conditioning system transports cold or heat to the end. There are several ways based on the transported medium. One is direct air supply, one is cold / hot water delivery, and one is direct refrigerant. For systems with direct air supply and cold / hot water delivery, the refrigerant pipelines are generally concentrated near the main unit. For systems that directly use refrigerant, such as VRV systems, the refrigerant pipeline will directly enter the air-conditioned space, connecting the outdoor main unit and the indoor unit, and the refrigerant pipeline is relatively long.

[0003] The traditional refrigerant pipe structure is connected at the end directly by expanding the pipe body. The connection end of the flared structure is easy to fall off during connection, which leads to low sealing performance and needs to be improved. Utility Model Content
