<p><P>PROBLEM TO BE SOLVED: To provide a cold system capable of surely heating hot water flowing through a hot water circuit without requiring any auxiliary heating means such as an electric heater. <P>SOLUTION: As an exhaust heat exchanger 13 capable of conducting heat exchange between refrigerant of a high temperature side flowing through a refrigerant circuit 30 and a cooling water flowing through a cooling water circuit 10 is provided in the refrigerant circuit 30 in parallel with a high temperature side heat exchanger 32, exhaust heat radiated from the refrigerant circuit 30 can be absorbed by the cooling water flowing through the cooling water circuit 10 and thus it is possible to save energy without requiring any auxiliary heat source such as an electric heater for heating the hot water flowing through the hot water circuit 20 even in the case that exhaust heat from a generator 2 is insufficient. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
