Abstract

The Stirling cooling storehouse (100) comprises: a Stirling refrigerator (13) having a radiating part (13a) and a heat absorbing part (13b); a cooling chamber cooled by the low-temperature heat of the heat absorbing part (13b); a secondary refrigerant circulation circuit for cooling the radiator (13a); and a tertiary refrigerant circulation circuit for exchanging heat with the secondary refrigerant circulation circuit.

Description

technical field [0001] The present invention relates to a Stirling cooler, and more particularly to a Stirling cooler that effectively utilizes the heat of a radiator of a Stirling refrigerator for preventing condensation, evaporating waste water, and the like. Background technique [0002] As a technology which applies the heat exchange by reverse Stirling cycle to a cooling store, the technology described in Unexamined-Japanese-Patent No. 2003-50073 is mentioned, for example. [0003] In the above-mentioned cooling store, there is disclosed a Stirling refrigeration system characterized in that the system has a high-temperature part that radiates to the outside the heat of compression of the working gas generated through the reverse Stirling cycle, and absorbs heat from the outside through the reverse Stirling cycle. The low-temperature part of the heat of expansion of the working gas generated by the cycle, and the low-temperature side circulation circuit, which is compose...
