PURPOSE:To improve a heat accumulation efficiency and further enable a large amount of heat to be accumulated by a method wherein a gas clathrate producing part of a cold heat accumulation tank of a cold heat accumulation system is arranged in the middle part of a cold heat accumulation cycle system and connected to a storing part having a pressure regulating pipe arranged therein. CONSTITUTION:A cold heat accumulation cycle system 1 is provided with a gas clathrate producing part 6 constituting a compressor 2, a condenser 3, an expansion valve 4 and a cold heat accumulation tank 5. In a radiation cold cycle 8 is arranged a storing part 13 constituting a circulation pump 9, an opening or closing valve 10, a heat exchanger 11 for heating exchanging with a load, an opening or closing valve 12, a gas clathrate producing part 6 and a cold heat accumulating tank 5. The gas clathrate producing part 6 and the storing part 13 are connected by a gas clathrate transmitting pipe 14. Some guest agents having a high specific gravity are accumulated at the lowest layer in the gas clathrate producing part, and some host agents are accumulated at the upper layer of the guest agent in a shallow water depth, resulting in that a liquid pressure of the host agents is low and the guest agents may easily evaporate. Accordingly, a cold heat accumulating efficiency can be improved and the gas clathrate is carried to the storing part and it is possible to make a large amount of capacity. |
