PURPOSE:To minimize the surplus or shortage of heat in a unit utilizing heat and utilize the heat of a heat source effectively as the whole of a system utilizing heat by a method wherein the movement of the heat among a plurality of units utilizing the heat are effected mutually in the form of hydrogen by employing a metallic hydride. CONSTITUTION:Heat medium, heated by solar heat collectors 12, 22, 32, is sent into the heat exchangers 15, 25, 35 of metallic hydride vessels 14, 24, 34 provided at the entrance port side of thermal loads through heat medium routes 13, 23, 33. The heat medium, whose temperatures are regulated by the exchange of the heat which is effected there, is supplied to the thermal loads 16, 26, 36 to drive the thermal loads. As a result, the heat medium, whose temperature is reduced, is sent into the heat exchangers 18, 28, 38 of the metallic hydride vessels 17, 27, 37 provided at the outlet port side of the thermal loads. In this case, the movement of hydrogen is effected among the metallic hydride vessels 14, 24, 34 at the inlet side of the thermal loads from opening and closing valves 41, 42, 43 through a hydrogen pipeline 47 while the movement of hydrogen is effected among the metallic hydride vessels 17, 27, 37 at the outlet side of the thermal loads from the opening and closing valves 44, 45, 46 through the hydrogen pipeline 48. |
