It is characterized by comprising means for mixing an additive into the heat storage tank, adjusting the mixing ratio thereof, and controlling the temperature taken out from the heat storage tank. That is, in the present invention, by adding additives such as ethanol, ethylene glycol, etc. to the host agent and the guest agent in the heat storage tank and adjusting the amount of addition, the decomposition temperature of the gas clathrate, that is, the decomposition temperature of the gas clathrate from the heat storage tank, can be adjusted. For example, gas clathrate is normally decomposed at the critical decomposition point shown in Figure 2, but by adding the amount of additive, the temperature can be changed from point B to point C. It has been made possible to lower the decomposition temperature of gas clathrates. In addition,
As the additive, any additive can be selected as long as it lowers the freezing point, such as ethanol and ethylene glycol.
