HEAT PUMP SYSTEM AND HEAT PUMP OPERATION METHOD
First Claim
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 an 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 first valve disposed in said supply channel and controlling a flow rate of vapor supplied to said external heat-utilizing facility.

Abstract
A compact heat pump system and a heat pump operation method, which can avoid the occurrence of surging in a compressor at startup of a heat pump and can directly supply vapor of a working medium produced by the compressor to an external heat-utilizing facility. The heat pump system comprises 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 the evaporator and increasing temperature of the evaporated working medium, and a driving unit for giving motive power to drive the compressor. The heat pump system further comprises a supply channel for supplying, as a heat source, vapor of the working medium having temperature increased by the compressor to an external heat-utilizing facility, and a return channel branched from the supply channel and introducing the working medium discharged from the compressor to the evaporator.

15. A heat pump operation method comprising the steps of:
-
performing heat exchange between a working medium supplied as liquid water from an exterior and an external heat source in an evaporator, thereby evaporating the working medium; driving a compressor by a driving unit and compressing the working medium evaporated in said evaporator, thereby producing vapor of the working medium having increased temperature; causing the vapor of the working medium to flow downstream back to said evaporator until the vapor of the working medium discharged from said compressor reaches a desired state; and supplying the vapor of the working medium to an external heat-utilizing facility after the vapor of the working medium discharged from said compressor reaches the desired state. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)
