つた。(C) Problems to be Solved by the Invention However, when a plurality of heat utilization units are installed independently as described above, even if there is excess or deficiency in heat in each unit, they cannot accommodate each other. As a result, the unit on the side with excess heat must discard the excess heat, and the unit on the side with insufficient heat must install an auxiliary heat source such as a heater to make up for the shortage. As described above, conventional heat utilization systems have a problem in that heat cannot be utilized efficiently.

効率の向上が図られる。(E) Effect The heat utilization system of the present invention is such that when the temperature of the heat medium in a certain heat utilization unit is higher than the heat load driving temperature, the metal hydride in the metal hydride container in that heat utilization unit is heated by the heat medium. The hydrogen gas generated is heated and dehydrogenated, and the generated hydrogen gas is introduced through hydrogen piping into the metal hydride container of another heat utilization unit whose heating medium temperature is lower than the heat load driving temperature, and the heat generated by the hydrogenation reaction is used to dehydrogenate the heating medium. The heat utilization efficiency of the entire heat utilization system can be improved.

Furthermore, by selecting a combination of metal hydrides to be filled in the metal hydride container, heat can be effectively transferred even between heat utilization units having different heat utilization temperature levels. Therefore, surplus heat generated by a single heat utilization unit can be effectively used in other heat utilization units, and the heat of the heat source can be effectively utilized as a whole of the heat utilization system. Furthermore, since the temperature level of the heat supplied to the heat source is adjusted, the heat utilization efficiency of the entire heat utilization system can be improved.

This is an example in which a heat utilization system is configured with 1 and 31. In each heat utilization unit 11, 21, 31, a heat medium (not shown) heated by a solar heat collector 12, 22, 32 (heat source) is transferred to a heat medium path 1.
3, 23, and 33 to the heat exchangers 15, 25, and 35 of the metal hydride containers 14, 24, and 34 provided on the heat load inlet side. There, heat is exchanged and the temperature of the heating medium is adjusted.Thermal load 16,
26 and 36 to drive the heat load. As a result, the heat medium whose temperature has decreased is further sent to the heat exchangers 18, 28, 38 of the metal hydride containers 17, 27, 37 provided on the heat load outlet side. Therefore,
The heating medium, whose temperature has been adjusted by transferring heat again, is returned to the solar heat collectors 12, 22, and 32 by the pumps 19, 29, and 39, and is circulated.

Hydrogen transfer is performed from 4, 45, and 46 via hydrogen pipe 48. These hydrogen transfers occur depending on the magnitude relationship of the heat load inlet temperature or the heat load outlet temperature of the heat medium between the heat utilization units 11, 21, and 31.

へ分配供給される。 For example, while the heat medium temperature at the heat load inlet of heat utilization unit 11 is high, other heat utilization units 2
When the heat medium temperature at the heat load inlets 1 and 31 is low, hydrogen gas moves from the heat utilization unit 11 to the heat utilization units 21 and 31. As a result, a hydrogen release reaction occurs in the metal hydride container 14, and a hydrogen release reaction occurs in the metal hydride container 2.
Hydrogen absorption reaction is carried out in the heat utilization units 21 and 34, and the surplus heat of the heat utilization unit 11 is transferred to the heat utilization units 21 and 31.

金属水素化物容器２７に移動する。 On the other hand, the heat load on the heat utilization unit 11 is large, and the temperature of the heat medium after passing through the heat load decreases.
If it is greater than 1, hydrogen gas moves from the metal hydride container 27 to the metal hydride container 17. Conversely, if the thermal load on the heat utilization unit 21 is large and the temperature drop of the heat medium after the heat load is greater than that on the heat utilization unit 11, hydrogen gas moves from the metal hydride container 17 to the metal hydride container 27.

る必要がある。 In this way, hydrogen gas moves according to the temperature difference of the heat medium. However, if all the hydrogen gas in the system is transferred to metal hydride containers such as 14 and 17 in one heat utilization unit, and
If there is insufficient heat in step 1, no further movement of hydrogen gas occurs, and heating of the heat medium in heat exchangers 15 and 18 becomes impossible. In such a case, it is necessary to use an auxiliary heat source in the heat utilization unit 11 to supplement the amount of heat. Further, the hydrogen gas in the metal hydride containers 14 and 17 is generated by heating the metal hydride in the metal hydride containers 14 and 17 at night using late-night electricity and dehydrogenating the metal hydride in each metal hydride container 14 and 17. , 24, 34 and 17, 2
It is necessary to move the hydrogen gas evenly within the containers 7 and 37 so that the distribution of hydrogen gas to each container is not uneven.
