PURPOSE: To enable a temperature taken out from a thermal accumulation tank to be selected at will during a heat discharging operation by a method wherein a proper amount of additive agent is added to a thermal accumulation tank in a thermal accumulation system in which a clathrate compound generated under a reaction between host agent and a guest agent is used as a thermal accumulation agent.
CONSTITUTION: During a thermal accumulating operation, an operation of a thermal discharging cycle is terminated through a stopped condition of a pump 7 and the thermal accumulation cycle is operated under an energization of a compressor 2. Freon gas is taken out from a gas region 12 within the thermal accumulation tank 1, sucked and compressed by a compressor 2, condensed within a condensor 5. The gas changes into a freon liquid and enters an expansion valve 9 and then adiabatically expands and enters the thermal accumulation tank 1. The freon liquid compounds with water acting as a host agent within the thermal accumulation tank 1 to generate a clathrate of gas. Guest agent for producing the gas clathrate compound i.e. a latent heat of the freon is stored in the thermal accumulation tank 1. During a thermal discharging operation, the pump 7 is started to operate to form a thermal discharging cycle. A cold heat temperature taken out can be freely selected according to an amount of added additive agent in advance in the thermal accumulation tank 1.
