PURPOSE:To improve an efficiency of production of gas clathrate and enable an accumulation of cold heat of high capacity to be attained even if a floor area at the gas clathrate producing part is small by a method wherein the gas clathrate producing part is arranged in the midway of a cold heat accumulating cycle system and a storing part is arranged in the midway of the thermal radiation cycle. CONSTITUTION:In case of an accumulated cold heat operation, gaseous Freon refrigerant R11 is taken out from a gas range of the gas clathrate producing part 6 of a cold heat accumulator tank 5 and then the refrigerant is compressed by a compressor 2. The compressed R11 enters a condenser 3, is condensed there, becomes a Freon liquid, enters an expansion valve 4. In this way, the refrigerant is adiabatically expanded and enters the gas clathrate producing part 6. R11 is evaporated within the gas clathrate producing part 6, water and R11 within the the clathrate producing part 6 are cooled by this evaporation heat and at the same time the evaporated R11 and water acting as host agent may react to each other to produce gas clathrate. An inside part of the gas clathrate producing part 6 is agitated by an agitator 7, thereby a contact area between the water and R11 is increased and further a production efficiency of the gas clathrate is increased. |
