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 meanshaving a compressor, a high pressure selector valve, and a low pressure selector valve, an expanding/compressing unithaving a room temperature endand a low temperature end, and a regenerating unithaving a room temperature endand a low temperature end, carries out heat transfer to a subject to be cooled, and is comprised of a flow path for working gas connecting the low temperature endof the expanding/compressing unit and the low temperature endof the regenerating unit with each other, and simultaneously extending to the subject to be cooled. 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.
