<P>PROBLEM TO BE SOLVED: To solve such a problem that when a plate type heat exchanger is used, in a condensing process for radiating condensed latent heat, excellent heat exchange is performed, but in a superheating area and a supercooling area where sensible heat is radiated, heat exchange efficiency is decreased, so that it is necessary that the size of a condenser is increased and consequently a refrigerating cycle device becomes enormous. <P>SOLUTION: There is provided a refrigerating cycle device including a compressor compressing a refrigerant, the condenser exchanging heat between the refrigerant compressed by the compressor and a fluid to be heated, superheating the fluid to be heated and condensing the refrigerant, and an evaporator evaporating the refrigerant condensed by the condenser. The condenser includes a first condenser comprising a heat transfer pipe for the refrigerant in which the refrigerant flows and a heat transfer pipe for the fluid to be heated in which the fluid to be heated flows and a second condenser comprising the plate type heat exchanger. The refrigerant is made to flow from the first condenser to the second condenser and the fluid to be heated is made to flow from the second condenser to the first condenser. In the first condenser and the second condenser, the refrigerant and the fluid to be heated are made to flow by counterflow, to exchange the heat. <P>COPYRIGHT: (C)2012,JPO&INPIT |
