Abstract:
1. A heat pump system comprising: an evaporator for recovering heat of an external heat source to a working medium supplied as liquid water from the exterior via a water feed channel, thereby evaporating the working medium; a compressor for compressing the working medium evaporated in said evaporator and increasing temperature of the evaporated working medium; a driving unit for providing motive power to drive said compressor; a supply channel for supplying, as a heat source, vapor of the working medium having temperature increased by said compressor to an external heat-utilizing facility; and a return channel branched from said supply channel and introducing the working medium discharged from said compressor to said evaporator; wherein the return channel is a different channel from the supply channel; and wherein the point where the return channel is branched from the supply channel is located between the compressor and the external heat-utilizing facility.
