  • Regenerative refrigerating apparatus
    Patent number: 7047749
    Abstract: A regenerative refrigerating apparatus which can increase the speed of cooling and heating a subject to be cooled. The specific constitution of the regenerating type refrigerating apparatus includes a pressure control means 4 having a compressor 4a, a high pressure selector valve 4b, and a low pressure selector valve 4c, an expanding/compressing unit 1 having a room temperature end 1a and a low temperature end 1b, and a regenerating unit 2 having a room temperature end 2a and a low temperature end 2b, carries out heat transfer to a subject to be cooled, and is comprised of a flow path for working gas connecting the low temperature end 1b of the expanding/compressing unit and the low temperature end 2b of the regenerating unit with each other, and simultaneously extending to the subject to be cooled 7.
    Type: Grant
