Cofluids for use with carbon dioxide refrigerant

A carbon dioxide/cofluid mixture is provided for use in a refrigeration cycle in which the carbon dioxide is alternately absorbed and desorbed from the cofluid. The mixture includes from 50% to 95% cofluid and from 5% to 50% carbon dioxide. The cofluid is selected so that the mixture falls within re...

More Information
Summary:A carbon dioxide/cofluid mixture is provided for use in a refrigeration cycle in which the carbon dioxide is alternately absorbed and desorbed from the cofluid. The mixture includes from 50% to 95% cofluid and from 5% to 50% carbon dioxide. The cofluid is selected so that the mixture falls within region A of the plot of pvap versus DELTAhsoln shown in FIG. 3. The DELTAhsoln of the mixture is the differential heat of solution of the carbon dioxide in the cofluid at 5 wt % and 0° C. The pvap of the mixture is the vapor pressure of the carbon dioxide over the solution at 20 wt % and 40° C.
