A new set of effective, environmentally safe, nonflammable, low-toxicity refrigerants, solvents, foam blowing agents, propellants, and firefighting agents is disclosed. The agents are clean, electrically nonconductive, and have short atmospheric lifetimes, zero ozone-depletion potential, and low global warming potentials. The agents comprise at least one fluoroiodocarbon agent satisfying the general formula CaHbBrcCldFeIfNgOh, wherein a is between and including 1 and 8; b is between and including 0 and 2; c, d, g, and h are each between and including 0 and 1; e is between and including 1 and 18; and f is between and including 1 and 2, either neat or mixed with additives selected from the group consisting of: alcohols, esters, ethers, fluoroethers, hydrocarbons, hydrofluorocarbons, and perfluorocarbons.

A method for providing refrigeration, comprising the steps of: (a) providing a refrigerating amount of a refrigerant composition in a cooling system, and (b) operating the cooling system, the refrigerant composition comprising a blend of at least one fluoroiodocarbon of the formula CaHbBrcCldFeIfNgO
A method for providing refrigeration, comprising the steps of: (a) providing a refrigerating amount of a refrigerant composition in a cooling system, and (b) operating the cooling system, the refrigerant composition comprising a blend of at least one fluoroiodocarbon of the formula CaHbBrcCldFeIfNgOh, wherein a is between and including 1 and 8, b is between and including 0 and 2, c, d, g and h are each between and including 0 and 1, e is between and including 1 and 17, and f is between and including 1 and 2, with at least one additive, the blend comprising 5 to 75 tool percent of the fluoroiodocarbon and 25 to 95 mol percent of the additive, the composition being nonflammable and electrically nonconductive, the fluoroiodocarbon having an ozone depletion potential less than 0.02 and a global warming potential less than that of chlorofluorocarbons, and the additive being nonreactive with the fluoroiodocarbon and not adversely affecting said properties of the fluoroiodocarbon.
