In at least some examples, the second component can be selected from the group consisting of carbon dioxide and pentafluoroethane. Further, the compositions can be azeotropic or azeotrope-like. ## Claims ### Claim 1 A refrigerant composition comprising a mixture of vinylidene fluoride and a second component, wherein the mixture has an ozone depletion potential of less than about 0.001, and a Global Warming Potential relative to carbon dioxide for an Integration Time Horizon of 100 years that is less than about 1,000. ### Claim 2 (depends on 1) The refrigerant composition of claim 1, wherein the second component comprises pentafluoroethane. ### Claim 3 (depends on 1) The refrigerant composition of claim 1, wherein the composition is an azeotropic or azeotrope-like composition. ### Claim 4 (depends on 1) The refrigerant composition of claim 1, wherein the composition comprises vinylidene fluoride in an amount from about 99 wt % to about 20 wt % based on the total weight of the composition, and pentafluoroethane in an amount from about 1 wt % to about 80 wt % based on the total weight of the composition. ### Claim 5 (depends on 4) The refrigerant composition of claim 4, wherein the composition comprises vinylidene fluoride in an amount from about 90 wt % to about 20 wt % based on the total weight of the composition, and pentafluoroethane in an amount from about 10 wt % to about 80 wt % based on the total weight of the composition. ### Claim 6 (depends on 4) The refrigerant composition of claim 4, wherein the composition comprises vinylidene fluoride in an amount from about 80 wt % to about 40 wt % based on the total weight of the composition, and pentafluoroethane in an amount from about 20 wt % to about 60 wt % based on the total weight of the composition. ### Claim 7 A method of using a composition as a refrigerant, the method comprising the steps of: providing a refrigeration system; and adding a composition as a refrigerant to the refrigeration system, the composition comprising vinylidene fluoride and a second component. ### Claim 8 (depends on 7) The method of claim 7, wherein the second component comprises pentafluoroethane. ### Claim 9 (depends on 7) The method of claim 7, wherein the composition in an azeotropic or azeotrope-like composition. ### Claim 10 (depends on 8) The method of claim 8, wherein the composition comprises vinylidene fluoride in an amount from about 99 wt % to about 1 wt % based on the total weight of the composition, and carbon dioxide in an amount from about 1 wt % to about 99 wt % based on the total weight of the composition. ### Claim 11 (depends on 8) The method of claim 8, wherein the composition comprises vinylidene fluoride in an amount from about 99 wt % to about 20 wt % based on the total weight of the composition, and pentafluoroethane in an amount from about 1 wt % to about 80 wt % based on the total weight of the composition. ### Claim 12 (depends on 8) The method of claim 8, wherein the composition comprises vinylidene fluoride in an amount from about 90 wt % to about 20 wt % based on the total weight of the composition, and pentafluoroethane in an amount from about 10 wt % to about 80 wt % based on the total weight of the composition. ### Claim 13 (depends on 8) The method of claim 8, wherein the composition comprises vinylidene fluoride in an amount from about 80 wt % to about 40 wt % based on the total weight of the composition, and pentafluoroethane in an amount from about 20 wt % to about 60 wt % based on the total weight of the composition. ### Claim 14 (depends on 7) The method of claim 7, wherein the method comprises the steps of: providing a refrigeration system that includes R508B as a refrigerant; removing R508B from the refrigeration system; and adding a composition as a refrigerant to the refrigeration system, the composition comprising vinylidene fluoride and a second component.
