PURPOSE:To operate a high-temperature heat load section by heat collected by a solar heat collector, and to operate a low-temperature heat load section by excessive heat by additionally providing a thermal medium circulating duct passing through one chamber of a heat exchanger for a hydrogen storage vessel and the solar heat collector with a bypass duct capable of passing the low-temperature heat load section. CONSTITUTION:A thermal medium heated by the solar heat collector 17 operates the high-temperature heat load section 18, and hydrogen generated through the decomposition of a heat accumulating material M1H3 in a heat accumulating vessel 1 by excessive heat quantity reacts with M2 in the hydrogen storage vessel 2 and the heat of reaction is moved to a thermal medium in one chamber 15 of the heat exchanger 10. The thermal medium is forwarded to the solar heat collector 17 by the circulating duct 22 to properly elevate the temperature of the collector, and passed through the bypass 23 and the low-temperature heat load section 19 is operated. When solar heat is insufficient and cannot be used directly in the high-temperature heat load section 18, hydrogen stored in the hydrogen storage vessel 2 as M2H is moved into the heat accumulating vessel 1 and reacted with M1 and heat quantity being generated is used. The thermal medium does not pass through the bypass 23 at that time. |
