PURPOSE:To store and stabilize natural energy to supply it as thermal energy or the like, by supplying a part of gas ejected from an expansion turbine as low temperature gas to outside, and supplying the residual gas as medium temperature gas to outside after storing in an ejected gas storage chamber. CONSTITUTION:The rotation speed of a wind turbine 15 is speeded up with a step-up gear 16 and transmitted to compressors 17, 18 to compress air with them. And air from the compressor 17 is taken out with a valve 19 for heat supply, and high temperature air isothermally compressed with the compressor 18 is stored in a high temperature air chamber 20 to be stabilized. Then the stored air in the chamber 20 is supplied, after supplying heat to a heat exchanging conductive wall 25, to an expansion turbine 21, and with the generated power a power generator 22 is operated. And a part of ejected low temperature air is taken out with a valve 24 for refrigerative use or the like, and the residual air is stored in a low temperature air chamber 23 and, after absorbing heat from the heat exchanging conductive wall 25, supplied to outside as medium temperature air. |
