Title:
極低温冷凍システム
Document Type and Number:
Japanese Patent JP7061955
Kind Code:
B2
Abstract:
To realize refrigeration in a cryogenic temperature zone with comparatively high efficiency, without using refrigerants of chlorofluorocarbons with ozon layer depletion effects or green house effects.SOLUTION: A cryogenic refrigeration system comprises: a thermoacoustic engine 90; a first refrigerant circulation passage C1 which includes either one of an absorption type refrigerator 50 or an adsorption type refrigerator, and circulates a first refrigerant between an evaporator 57 of either one of the absorption type refrigerator 50 or the adsorption type refrigerator and a radiator 82; and a second refrigerant circulation passage C2 which circulates a second refrigerant between a heat exchanger EX3 heat-exchanging gas in a freezer FZ and the second refrigerant and a heat sink 81.SELECTED DRAWING: Figure 1
