HOT WATER SUPPLY DEVICE ASSOCIATED WITH HEAT PUMP

WIPO Patent Application WO/2011/149152

A1

Provided is a hot water supply device associated with a heat pump. The hot water supply device uses a cascade heat pump including a two-stage cycle to perform a hot water supply operation. Refrigerants flowing through a heat side heat exchanger and a usage side heat exchanger are heat-exchanged with water. Thus, the hot water supply operation is continuously performed without a defrosting operation, and a hot water supply performance and a heating performance can be improved.
