Title:
REFRIGERATING MACHINE
Document Type and Number:
Japanese Patent JP3766507
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To remarkably make rapid progress of refrigerating ability, by using ErNi as cool storage material of a cool storage unit of a refrigerating machine, and applying a magnetic field to the material.
SOLUTION: A refrigerating machine comprises a magnetic field applying means 6 for applying a magnetic field to the vicinity of a cool storage unit 1 of a conventional refrigerating machine. A suitable magnet such as a permanent magnet or an electromagnet can be used as the means 6, and magnetic field control of the means 6 can be conducted by a suitable means. Cool storage material used for the unit 1 of the machine is ErNi, and the field can be applied in various state to the material by the means 6. Thus, refrigerating ability can be largely improved as compared with conventional gas refrigerating machine. And, an intensity of the field to be applied to the material is changed synchronously with a refrigerating machine cycle to thereby easily increase refrigerating ability.
