Abstract: A heat supplier may include a compressor that compresses a refrigerant; a first heat exchanger that exchanges heat between air and the refrigerant; a second heat exchanger that exchanges heat between a fluid and the refrigerant; a switching valve that directs the refrigerant discharged from the compressor into the first heat exchanger or the second heat exchanger; a first liquid pipe that connects the first heat exchanger and the second heat exchanger; a second liquid pipe connected in parallel to the first liquid pipe so as to connect the first heat exchanger and the second heat exchanger; a first expansion valve disposed at the first liquid pipe and configured to expand refrigerant flowing therethrough; and a second expansion valve disposed at the second liquid pipe and configured to expand refrigerant flowing therethrough. A size of an aperture of the second expansion valve may be greater than a size of an aperture of the first expansion valve, enabling a flow rate of refrigerant to be adjusted according to an operation mode.

Abstract: 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.
