PROBLEM TO BE SOLVED: To solve problems that, in a heat pump recovering heat from low-temperature heat by using a steam compressor to supply high-temperature high-pressure steam, efficiency is deteriorated as a temperature difference increases, and the heat pump tries to recover heat at lower temperatures. SOLUTION: In a heat pump 3 generating working medium steam at low pressure by using a low-temperature heat source and compressing the working medium steam by a compressor to covert it to high-temperature high-pressure steam and supplying the steam, an absorption heat pump using a low-temperature heat source medium of which the temperature is lowered by generating working medium steam as a drive heat source is operated so as to generate working medium steam with a higher temperature than that of the drive heat source. The high-temperature working medium steam is also compressed to high-temperature high-pressure steam by the compressor 2, and is supplied. COPYRIGHT: (C)2011,JPO&INPIT
