A carbon dioxide/co-fluid mixture is provided for use in a refrigeration cycle in which the carbon dioxide is alternately absorbed and desorbed from the co-fluid. Suitable co-fluids are selected from the class of alkoxylated carboxylic amides, wherein the amides are cyclic or non-cyclic. It has been discovered that N-2,5,8,11-tetraoxadodecyl-2-pyrrolidinone and its homologs exhibit an advantageous property of a high rate of desorption at lower temperatures.
提供了一种二氧化碳/共溶液混合物,用于制冷循环,其中二氧化碳交替地被共溶液吸收和脱附。适当的共溶液是从烷氧基化羧酰胺类中选择的,其中酰胺是环状或非环状的。发现N-2,5,8,11-四氧十二烷基-2-吡咯烷酮及其同系物在较低温度下具有高脱附速率的优越性质。
