However, it was necessary to desorb the water vapor from the zeolite, condense it in a container containing water, and then shut off the valve to keep the adsorption operation of the water vapor on the zeolite in an interrupted state. However, since the conventional electromagnetic valve used packing for the seal part,

It is configured so that it is constantly sealed by a spring pressure inserted in the other end of the movable element, and this release is performed by an electromagnet arranged in contact with the outer wall surface of the hollow body, and there is no place to use packing. Therefore, by arranging it between the container containing zeolite and the container containing water, it is possible to eliminate the occurrence of leaks through conventional packing, and the tip of the movable element penetrates the orifice hole due to spring pressure. Since it is hermetically closed, no leak occurs between the containers. By arranging such an electromagnetic valve, the performance of the reversible cold heat generator at the beginning of manufacture can be maintained for a long period of time.

加熱冷熱の発生を生じる。In FIG. 1, when the valve 6 is shut off in the state where the initial vacuum process is completed in advance, the valve 6 is energized to open it, and the zeolite 2 contained in the container 1 becomes water 4
The water vapor filled in the space of the container 3 accommodating the water is strongly adsorbed and the water vapor pressure in the space of the container 3 sharply decreases, so that the evaporation of the water 4 is promoted and the heat of the water 4 is taken away to continue the evaporation. Adsorbed by 2. During this process, the temperature of the water 4 approaches the freezing point, and the zeolite 2 generates heat of adsorption and the container 1
Raise the temperature of. When this phenomenon is interrupted or controlled to a certain temperature, the valve 6 is opened and closed. When the adsorption capacity of the zeolite 2 is exhausted or the capacity is greatly reduced, the valve 6 is energized, the container 1 is heated in the open state to desorb the adsorbed water vapor and returned to the container 3, and the energization is stopped to turn off the valve 6. Shut off and wait for next use. In response to such operation of the electromagnetic opening / closing valve, FIG. 2 shows a state in which the electromagnetic opening / closing valve is closed. The electromagnetic on-off valve is arranged so that the orifice 12 side in FIG. 2 is connected to the low pressure side of the container 1 in FIG. 1 so that the sealing effect becomes more effective. In Figure 2,
The place where the water vapor exists is a communication hole 9 leading to the orifice 12, a conical tip portion 11 of the movable element 10, a cavity surrounded by the orifice 12 and the cylindrical hollow inner wall 8, and the orifice 12 and the conical tip portion. Blocked by 11 close penetrations. This breaking force is generated by the spring 17. By arranging the electromagnetic opening / closing valve as described above, the force for strongly adsorbing the zeolite 2 in the container 1 in FIG.
It acts on the close penetration portion between the conical tip portion 12 and the conical tip portion 11 to increase this close contact force and effectively perform blocking. Since both ends of the cylindrical hollow body 7 of the electromagnetic opening / closing valve are arranged in the containers 1 and 3 in FIG. 1 by welding, infiltration of outside air does not occur at all. This operation generates an electromagnetic force sufficient to overcome the force of the spring 17 by energizing the electromagnet 18 arranged in contact with the outer wall 7a of the cylindrical hollow body 7, and the gap 15 is filled so that the orifice hole 13 part is formed. In the open state, water vapor passes and is adsorbed by the zeolite to generate heating and cooling heat.
