Abstract:
A method for providing refrigeration comprising:(A) compressing a multicomponent refrigerant fluid comprising at least one hydrocarbon and at least one component from the group consisting of hydrocarbons, fluorocarbons, hydrofluorocarbons, fluoroethers and atmospheric gases;(B) cooling and at least partially condensing the compressed multicomponent refrigerant;(C) expanding the at least partially condensed multicomponent refrigerant fluid to generate refrigeration; and(D) warming and at least partially vaporizing the refrigeration bearing multicomponent refrigerant fluid and employing refrigeration from the multicomponent refrigerant fluid in an insulated enclosure wherein the warming and at least partially vaporizing of refrigeration bearing multicomponent refrigerant fluid is by heat exchange with insulated enclosure atmosphere fluid to produce refrigerated insulated enclosure atmosphere fluid and further comprising(E) employing the refrigerated insulated enclosure atmosphere fluid within an insulated enclosure to provide refrigeration to the insulated enclosure.
