Magnetic Refrigeration System With Single Direction Coolant Devices And Vehicle Air Conditioning Device Applications

摘要

A magnetic refrigeration system constructed in such a way that a refrigerant transfer part transfers refrigerant from a first refrigerant discharge part of one refrigerant port to a first refrigerant circulation circuit after a magnetic field is applied to a magnetic working material by a magnetic field applying and removing part and that the refrigerant transfer part transfers refrigerant from a second refrigerant discharge part of other refrigerant port to a second refrigerant circulation circuit after the magnetic field is removed from the magnetic working material by the magnetic field applying and removing part.

主权项

1. A magnetic refrigeration system comprising:
a cylindrical container having a plurality of working chambers formed therein radially in a circumferential direction, the plurality of working chambers having a magnetic working material having a magnetocaloric effect arranged therein and having refrigerant flowing therethrough, the cylindrical container having one refrigerant port and another refrigerant port respectively on end faces in a longitudinal direction; a magnetic field applying and removing part which repeats applying and removing a magnetic field to and from the magnetic working material; a first refrigerant circulation circuit constructed in such a way that the refrigerant flowing out of a first refrigerant discharge part of the one refrigerant port flows through a first heat exchanger and returns to a first refrigerant suction part of the one refrigerant port; a second refrigerant circulation circuit constructed in such a way that the refrigerant flowing out of a second refrigerant discharge part of the another refrigerant port flows through a second heat exchanger and returns to a second refrigerant suction part of the another refrigerant port; a refrigerant transfer part which transfers the refrigerant between the first refrigerant discharge part and the first refrigerant suction part of the one refrigerant port and between the second refrigerant discharge part and the second refrigerant suction part of the another refrigerant port; a suction valve provided to each of the first refrigerant suction part and the second refrigerant suction part and opened when the refrigerant is sucked into the working chambers; and a discharge valve provided to each of the first refrigerant discharge part and the second refrigerant discharge part and opened when the refrigerant is discharged from the working chambers, wherein after the magnetic field is applied to the magnetic working material by the magnetic field applying and removing part, the refrigerant transfer part transfers the refrigerant from the another refrigerant port to the one refrigerant port, after the magnetic field is removed from the magnetic working material by the magnetic field applying and removing part, the refrigerant transfer part transfers the refrigerant from the one refrigerant port to the another refrigerant port, and the discharge valve is arranged at a position nearer to the working chambers than the suction valve is in the longitudinal direction of the container.
