HEAT UTILIZING SYSTEM UTILIZING HYDROGEN STORAGE ALLOY

摘要

PROBLEM TO BE SOLVED: To improve cooling capability by raising a pressure difference in containers for storing and discharging hydrogen. SOLUTION: When a hydrogen driverαsupplies heated water to a first container S1 for sealing a high-temperature alloy to raise its internal pressure, and supplies radiant water to a third container S3 for sealing a low-temperature alloy after a given time E for assuring the difference is elapsed to lower the internal pressure; hydrogen is rapidly moved from the high to the low- temperature alloys. When a first cold heat output unit supplies radiant water to a second container S2 for sealing an intermediate-temperature alloy to lower its internal pressure and supplies cold heat output water to the container S3 for sealing the alloy after a predetermined time B for assuring the difference is elapsed to raise the internal pressure, hydrogen is rapidly moved from the low- to the intermediate-temperature alloys. A second cold heat output unit supplies radiant water to a first alloy S1 for sealing a high-temperature alloy to lower the pressure and supplies cold heat output water to the second, third containers for sealing the intermediate and low temperature alloys after a given time C assuring the difference is elapsed to raise the pressure. As a result, cooling capability is enhanced.
