The object of the present invention is to provide a heat pump having a high coefficient of performance (COP), and a heat utilizing apparatus that allows the obtaining of high energy efficiency by using that heat pump. The heat pump, comprising a refrigerant circuitthat contains a decomposerin which a gas hydrate decomposition process is carried out and a formerin which a gas hydrate formation process is carried out. This refrigerant circuitimparts heat to a high-temperature object in the gas hydrate formation process by taking up heat from a low-temperature object in the gas hydrate decomposition process. In addition, the heat pump comprises at least an excess water separatorthat separates excess water from the gas hydrate formed in former, or a compression system that sends gas and liquid which are decomposition products of the gas hydrate decomposed in decomposerto formerafter compressing and mixing.

Heat pump using gas hydrate, and heat utilizing apparatus

The present invention relates to an exhaust heat recovery system that recovers exhaust heat that is generated by an electrical power generator for use in supplying hot water and air conditioning, and has as an object of providing an exhaust heat recovery system that realizes reduced costs and has a high energy efficiency. The exhaust heat recovery system provides a heat exchanger HEXfor exhaust heat recovery that heats heating medium by heat exchange between exhaust gas generated at the power generator and heating medium that is circulated and used in a predetermined facility. In addition, the exhaust heat recovery system comprises a tankthat temporarily stores the heating medium, and an open-air pipethat releases the contents of the tank
