REFRIGERATION METHOD AND APPARATUS

A method and apparatus of refrigerating a heat load in which heat is indirectly exchanged between the heat load and a cryogenic refrigerant so that the heat load cools. Further heat is then indirectly exchanged between the heat load and the mechanical refrigerant. The mechanical refrigerant is subje...

Zusammenfassung:	A method and apparatus of refrigerating a heat load in which heat is indirectly exchanged between the heat load and a cryogenic refrigerant so that the heat load cools. Further heat is then indirectly exchanged between the heat load and the mechanical refrigerant. The mechanical refrigerant is subjected to refrigeration cycle in which the mechanical refrigerant is compressed, cooled, condensed, expanded and evaporated. Other heat is indirectly exchanged between the cryogenic refrigerant and the mechanical refrigerant. The cryogenic refrigerant is subjected to its heat exchange with the mechanical refrigerant after having exchanged heat with the heat load. The mechanical refrigerant is subjected to the indirect heat exchange with the cryogenic refrigerant between condensation and expansion of the mechanical refrigerant within the refrigeration cycle.
