れにより熱効率が大幅に上昇する。(E) Action For example, when used as a heating device, the hydrogen gas transfer device transfers hydrogen gas from one set of metal hydride heat exchangers to the other set of metal hydride heat exchangers.
As a result, heat is generated in the other metal hydride heat exchanger, and the heat medium passage of this metal hydride heat exchanger is connected to the heat medium passage of the indoor heat exchange unit.
On the other hand, the heat exchanger for one metal hydride absorbs heat,
The heat medium passage of the metal hydride heat exchanger is connected to the heat medium passage of the heat source heat exchange unit. When the transfer of a predetermined amount of hydrogen gas from the one metal hydride heat exchanger to the other metal hydride heat exchanger is completed, the transfer of hydrogen gas by the hydrogen gas transfer device is stopped. At this point, the flow direction of the heat medium is not switched. Therefore, at this point, the amount of heat possessed by the other metal hydride heat exchanger is used for heating. In this state, the operation of the hydrogen gas transfer device is restarted after a lapse of a predetermined time, but the flow direction of the hydrogen gas is opposite to the flow direction of the previous operation. When the flow direction of the hydrogen gas reverses, the temperature of the other metal hydride heat exchanger starts to decrease, and the one metal hydride heat exchanger starts to increase. At the same time, the heat medium passage switching device is switched, and the combination of the connection between the heat exchangers for both metal hydrides and both heat exchange units is reversed from the state up to that point. Thereby, heating is continuously performed in the indoor heat exchange unit, and heat is absorbed in the heat source heat exchange unit. The above-mentioned predetermined time for deactivating the hydrogen gas transfer device is, for example, such that the amount of heat obtained is maximum, that is, the time at which the heat medium inlet temperature of the metal hydride heat exchanger and the heat medium outlet temperature become equal. Can be This significantly increases thermal efficiency.

The hydrogen gas moving device is operated so as to move the hydrogen gas to the heat exchanger for metal hydride, and at the same time, the heat medium passage and the heat medium passage of the two sets of metal hydride heat exchangers are used by the heat medium passage switching device. A method of controlling a heating / cooling device using a metal hydride, characterized in that the combination of the unit and the heat exchange unit for the heat source with the passage for the heat medium is opposite to the previous combination of connections.
