ヒートポンプ装置及びヒートポンプの運転方法

Japanese Patent JP5151014

B2

A compact heat pump system and a heat pump operation method, which can avoid the occurrence of surging in a compressor (34) at startup of a heat pump and can directly supply vapor of a working medium produced by the compressor (34) to an external heat-utilizing facility (20). The heat pump system comprises an evaporator (42) for recovering heat of an external heat source (40) to a working medium supplied as liquid water from the exterior via a water feed channel (31), thereby evaporating the working medium, a compressor (34) for compressing the working medium evaporated in the evaporator (42) and increasing temperature of the evaporated working medium, and a driving unit (1) for giving motive power to drive the compressor (34). The heat pump system further comprises a supply channel (24) for supplying, as a heat source, vapor of the working medium having temperature increased by the compressor (34) to an external heat-utilizing facility (20), and a return channel (22) branched from the supply channel (24) and introducing the working medium discharged from the compressor (34) to the evaporator (42).
