When the cooling operation is instructed by the controller of the indoor air conditioner 5, the control device 6 controls the combustion device 3, the cell moving means, the radiating fan and the heated water circulating pump P1 (pressurized water circulating pump P1 '), the cooling water output water pump P2, and the radiating heat. When the water circulation pump P3 operates,
The indoor fan 20 of the indoor air conditioner 5 for which cooling is instructed is turned on.

The plurality of cells S are slowly and continuously rotated by the cell moving means. As a result, the plurality of cells S move in the order of the hydrogen drive unit α → the first cold output unit β → the second cold output unit γ. That is, each upper cell container S1
Moves in the order of heating zone α1 → upper boost zone β1 → upper heat dissipation zone γ1 and each middle cell vessel S2 moves in the order of middle boost zone α2 → middle heat dissipation zone β2 → middle cooling output zone γ2, and each lower cell The vessel S3 moves in the order of the lower heat radiation area α3, the lower cooling power output area β3, and the non-interest area γ3.

In the cell S that has entered the hydrogen drive section α, the upper cell container S1 contacts heated water, the middle cell container S2 contacts pressurized water, and the lower cell container S3 contacts facility water. When the upper cell container S1 comes into contact with the heated water (80 ° C.), the internal pressure of the upper cell container S1 increases, and the high-temperature alloy HM releases hydrogen. When the middle cell container S2 comes into contact with the pressurized water (56 ° C.), the internal pressure of the middle cell container S2 rises to a pressure at which the middle temperature alloy MM does not absorb hydrogen. Lower cell container S3
Touches the facility water (28 ° C.), the internal pressure of the lower cell container S3 decreases, and the low-temperature alloy LM stores hydrogen.

As described above, the upper cell container S1 has the heating zone α.

The high-temperature alloy HM of the upper cell container S1 releases hydrogen (FIG. 6), and the low-temperature alloy LM of the lower cell container S3 stores hydrogen (FIG. 6). The middle cell container S2 is heated by the pressurized water and has a high internal pressure, and the medium temperature alloy MM does not occlude hydrogen. Then, the cell S that has passed through the hydrogen driving unit α moves to the first cooling / heating unit β.

In the cell S that has entered the first cooling output section β, the upper cell container S1 contacts the pressurized water, the middle cell container S2 contacts the facility water, and the lower cell container S3 contacts the cooling output water.
When the upper cell container S1 comes into contact with the pressurized water (58 ° C.), the internal pressure of the upper cell container S1 rises to a pressure at which the high-temperature alloy HM does not absorb hydrogen. When the middle cell container S2 comes into contact with facility water (28 ° C.), the internal pressure of the middle cell container S2 decreases, the medium temperature alloy MM absorbs hydrogen, and the low temperature alloy LM of the lower cell container S3 releases hydrogen. Low temperature alloy LM
Releases hydrogen, heat is absorbed in the lower cell container S3 and the cold output water that touches the lower cell container S3 is, for example, 7 ° C.
Cooled down. The low-temperature alloy LM has a cooling output water of 1
At about 3 ° C., the internal pressure of the lower cell container S3 is set to be higher than the internal pressure of the middle cell container S2.

As described above, the upper cell container S1 touches the pressurized water in the upper pressurized region β1, the middle cell container S2 touches the facility water in the middle heat dissipated region β2, and the lower cell container S3 outputs the cold output of the lower cool output region β3. By contact with water, the inside of the upper cell container S1 is 58 ° C .; 0.5 MPa, the inside of the middle cell container S2 is 28 ° C .; 0.4 MPa, the inside of the lower cell container S3 is 13 ° C .;
0.5MPa, low temperature alloy LM of lower cell container S3
Releases hydrogen (FIG. 6), and the medium temperature alloy MM in the middle cell container S2 stores hydrogen (FIG. 6). When the low-temperature alloy LM of the lower cell container S3 releases hydrogen, heat is taken from the cold output water that touches the lower cell container S3 by an endothermic action to lower the temperature of the cold output water. The upper cell container S1
Is heated by pressurized water, the internal pressure is high, and the high temperature alloy H
M does not occlude hydrogen. And the first cooling / heating output section β
After that, the cell S moves to the second cooling / heating output section γ.

In the cell S that has entered the second cooling output section γ, the upper cell container S1 comes into contact with facility water, the middle cell container S2 comes into contact with cold output water, and the lower cell container S3 comes into contact with water.
When the upper cell container S1 comes into contact with facility water (28 ° C.), the internal pressure of the upper cell container S1 decreases, the high-temperature alloy HM absorbs hydrogen, and the medium-temperature alloy MM in the middle cell container S2 releases hydrogen. Since the middle temperature alloy MM releases hydrogen, heat is absorbed in the middle cell container S2, and the cold output water that touches the middle cell container S2 is cooled to, for example, 7 ° C. The medium temperature alloy MM is provided such that the internal pressure of the middle cell container S2 becomes higher than the internal pressure of the upper cell container S1 when the cooling output water is about 13 ° C.

As described above, when the upper cell container S1 comes into contact with the facility water in the upper heat radiation area γ1, the upper cell container S1
28 ° C .; 0.1 MPa, 13 in the middle cell container S2
.Degree. C .; 0.2 MPa, the inside of the lower cell container S3 becomes unquestioned, the medium temperature alloy MM of the middle cell container S2 releases hydrogen (FIG. 6), and the high temperature alloy HM of the upper cell container S1 absorbs hydrogen (FIG. 6). 6). When the medium temperature alloy MM in the middle cell container S2 releases hydrogen, heat is taken from the cold output water that comes into contact with the middle cell container S2 by an endothermic action to lower the temperature of the cold output water. The temperature of the lower cell container S3 is irrelevant, and the low-temperature alloy LM of the lower cell container S3 does not occlude hydrogen. Then, the cells S that have passed through the second cooling / heating output section γ
Moves to the hydrogen driving unit α thereafter.

The low-temperature cold output water whose heat has been deprived in the lower-stage cold output region β3 and the middle-stage cold output region γ2 of the heat pump cycle 2 passes through the cold output water circulation path 21 to the indoor heat exchanger of the indoor air conditioner 5. The heat is exchanged with the air blown into the room, and the room is cooled.

However, three large radial seals are sufficient, and the number of seal locations can be reduced. Since the heat medium containers 9 in each stage are provided by a resin material having high heat insulating properties, the sliding portions between the heat medium containers 9 in each stage and the upper, middle, and lower heat medium supply / discharge means K1, K2, and K3 are provided. The heat loss that the heat of the heat medium transfers to the other is reduced. A supply / discharge port 9b of the heat medium container 9 of each stage is provided on a peripheral surface parallel to the rotating shaft 8, and

Leaks, the leaked heat medium does not mix with other heat medium. For this reason, a heat loss caused by the leaked heat medium being mixed into the adjacent one does not occur, and a decrease in the cooling capacity of the heat pump cycle 2 can be prevented. In this embodiment, since the heat medium containers 9 in each stage are integrally molded, the supply / discharge ports 9b are arranged in a perfect circle, and the upper, middle, and lower heat medium supply / discharge means K1, K2, and K3 are excellent in sealing performance. .
