Description
技术领域technical field

The low-temperature and low-pressure refrigerant liquid that has been throttled and reduced is absorbed in the heat exchange tube The heat of the external ambient air evaporates into a low-temperature and low-pressure gas; in summer, the refrigeration cycle acts as a condenser, and the high-temperature and high-pressure refrigerant gas discharged from the compressor releases heat to the external ambient air in the heat exchange tube, and condenses into a high-temperature and high-pressure liquid. In the cycle of summer and winter, the direction of the refrigerant entering and exiting changes, especially the flow direction conversion of the evaporator with a liquid separator and the condenser. The usual system piping connections are complicated and cannot meet the problem of condensed liquid collection when used as a condenser. Therefore, it is of great significance to develop a circulation system with simple structure and convenient operation and control to save pipeline consumables, reduce costs, reduce pipeline resistance loss, improve circulation efficiency, save energy and protect the environment.
