HOT WATER SUPPLY APPARATUS ASSOCIATED WITH HEAT PUMP

摘要

A hot water supply apparatus associated with a heat pump is provided. The hot water supply apparatus may employ 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 may be heat-exchanged with water. Thus, the hot water supply operation may be continuously performed, without a defrosting operation, and hot water supply performance and heating performance may be improved.
