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 means4having a compressor4a, a high pressure selector valve4b, and a low pressure selector valve4c, an expanding/compressing unit1having a room temperature end1aand a low temperature end1b, and a regenerating unit2having a room temperature end2aand a low temperature end2b, carries out heat transfer to a subject to be cooled, and is comprised of a flow path for working gas connecting the low temperature end1bof the expanding/compressing unit and the low temperature end2bof the regenerating unit with each other, and simultaneously extending to the subject to be cooled7. Consequently, it is possible to significantly increase the utilization ratio of the refrigerating apparatus, and to widely apply the refrigerating apparatus to sensors and semiconductor manufacturing apparatuses.
