Abstract
A heat pump system includes: a compressor for compressing refrigerant; a first heat exchanger for exchanging heat between the refrigerant compressed by the compressor and a heating medium; a second heat exchanger for exchanging heat between the refrigerant compressed by the compressor and the heating medium; a first pipe through which the refrigerant is fed from the compressor to the first heat exchanger; a second pipe through which the refrigerant returns from the first heat exchanger to the compressor; a third pipe through which the refrigerant is fed from the compressor to the second heat exchanger after returning from the first heat exchanger; and switching apparatus for switching a flow of the heating medium between a first mode and a second mode. The heating medium flows through the first heat exchanger and the second heat exchanger in series in the first mode. The heating medium flows through the first heat exchanger and the second heat exchanger in parallel in the second mode.
