ABSTRACT:
This duplex-type heat exchanger is adapted to a vapor compression type refrigeration cycle in which a condensed refrigerant is decompressed and then evaporated. This duplex-type heat exchanger is integrally equipped with a subcooler S in which the condensed refrigerant exchanges heat with the ambient air A to be subcooled and an evaporator E in which the decompressed refrigerant exchanges heat with the ambient air A to be evaporated. Heat exchange is performed between the refrigerant passing through the subcooler S and the refrigerant passing through the evaporator E, to thereby cool the refrigerant in the subcooler S and heat the refrigerant in the evaporator E. Accordingly, according to this heat exchanger, a high refrigeration effect can be obtained while avoiding the pressure rise of the refrigerant.
