As one of the four major parts of t

As one of the four major parts of the refrigeration unit, the condenser belongs to an indispensable key position, and it also belongs to a kind of heat exchanger like the evaporator. its work is to condense the high-temperature and high-pressure refrigerant vapor into a liquid during the flow of the refrigerant through the condenser, and at the same time radiate the heat brought by the refrigerant to the external medium. In the heat pump unit, the high temperature and high pressure saturated refrigerant steam from the evaporator is condensed and released in the condenser, and then the heat energy is used to heat the feed water. The condenser plays an indispensable key role in the refrigeration system, and its quality directly affects the performance of the refrigeration equipment. In order to improve the performance of the refrigeration system and reduce its energy consumption, it is necessary to improve the structure of the condenser and ensure its important role in enhancing heat transfer [6]. Therefore, the choice of a quality pass condenser is also very critical, poor quality condenser will lead to many problems.
