HEAT PUMP USING GAS HYDRATE, AND HEAT UTILIZING APPARATUS

摘要

A heat pump, comprising a refrigerant circuit (13) having a decomposer (20) in which a gas hydrate decomposing process is performed and a generator (25) in which a gas hydrate generating process is performed. The refrigerant circuit (13) absorbs heat from a low temperature object in the gas hydrate decomposing process and providing heat to a hot object in the gas hydrate generating process. The heat pump also comprises at least one of an excess water separator (40) separating excess water from gas hydrate generated by the generator (25) and a compression system feeding, compressing, and mixing gas and liquid as the decomposed matters of the gas hydrate decomposed by the decomposer (20) and feeding the mixture to the generator (25). Thus, the heat pump with a high coefficient of performance (COP) and a heat utilizing apparatus capable of providing a high energy efficiency by using the heat pump can be provided.
