ら能力のある磁気冷凍サイクルを行うことができる。Let us take as an example a case where the indoor temperature is lower than the outdoor temperature and the room is to be cooled. Prior to the start of operation, the indoor cold storage liquid circulation device 8 and the outdoor cold storage liquid circulation device 9 are activated to circulate the cold storage liquid that has passed through the indoor heat exchanger 2 through the outdoor side on the low temperature side. The cool storage liquid is circulated on the high-temperature side, and kept at a low temperature on the heat-absorbing side and a high temperature on the heat-radiating side. In this case, for example, the cold storage liquid on the high temperature side is heated by a heater or the like, and a temperature difference is given between it and the cold storage liquid on the low temperature side. As long as there is a temperature difference between the two, the cold storage liquid on the low temperature side may be cooled in advance with cold water or the like. Then, the cooling operation is started by reciprocating the magnetic working material 6. In this way, by creating a temperature difference inside the device before operating the magnetic refrigerator, the entropy of the magnetic refrigeration applied at the start of operation is increased, and a magnetic refrigeration cycle with high capacity can be achieved from the start of operation. It can be carried out.
