Refrigerant heat exchanger for heat pump type heating and cooling system

摘要

This research is about the heat and cold exchange device of heat pump system,High temperature refrigerant,With high-pressure compressors and,When air conditioning or heating, the 4-way valve that can change the direction of refrigeration medium circulation,The heat pump type dual-purpose cooling and heating system consists of evaporator and condenser,Between the infusion set at the outlet of the condenser and the expansion edge at the inlet of the evaporator,The interior is empty, and the upper side of the extension is the low-temperature gas inlet introduced by the low-temperature refrigerant flowing out of the evaporator outlet,On the other side, in order to combine with the suction filter connected with the compressor, a rotary cylindrical main engine is set,Inside the main engine, the liquid pipe of the high temperature and high pressure refrigerant from the infusion set to the expansion side is inserted and penetrated,By configuring the radiating fins to protrude in the longitudinal direction on the outer periphery of the liquid pipe inserted in the main body, even if the outdoor temperature drops below -15 ℃ during heating of the condensed iron, the efficiency of heat absorption in the evaporator is increased to maximize the heating effect. Make it possible,In summer, air conditioning can improve its efficiency, cop and overall thermal efficiency of the system,Through the simplification of pipeline, the installation cost can be reduced.
