Heat pump using gas hydrate, and heat utilizing apparatus

A heat pump, comprising:

• a refrigerant circuit, which contains a decomposer in which a gas hydrate decomposition process is carried out, and a former in which a gas hydrate formation process is carried out, and imparts 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,
• a first line though which gas flows, the gas being a decomposition product of the gas hydrate decomposed in the decomposer;
• a second line through which liquid flows, the liquid being a decomposition product of the gas hydrate decomposed in the decomposer;
• and
• a compression system that is connected to the first and the second lines, and that mixes the gas from the first line with the liquid from the second line, and that sends the gas and the liquid to the former after compressing and mixing.

• an excess water separator that separates excess water from the gas hydrate formed in the former, the gas hydrate after the separation of the excess water being supplied to the decomposer,
• a first line though which gas flows, the gas being a decomposition product of the gas hydrate decomposed in the decomposer;
• a second line through which liquid flows, the liquid being a decomposition product of the gas hydrate decomposed in the decomposer;
