Because of their environmental impact an international protocols and thegoals established by Russian Federal Government Decree № 228 designed 14.03.2014 to phase out completely production of the CFCs and HCFCs halogenated compounds are considered. These impending a new urgency in the search for replacement fluids. The new refrigerants should be environment   friendly with zero ODP and low GWP. It should also meet many conflicting criteria: a good thermodynamic efficiency  and heat transfer properties  it should be safe  (non-toxic, non-flammable). R22 and another HCFC-refrigerants is now being ruled out because of its alleged adverse effect to the environment. Alternatives must be sought  among the HFCs but among these non of the pure compounds  can pretend  to be substitute to R22 through its whole range of applications. The compounds that might be replaced   and the hydrogen-containing compounds are listed. Emerging alternatives to CFCs and HCFCs include newly developed refrigerants, innovative designs and strong federation control. The regulations by RF Government Decree № 228 designed 14.03.2014 issued the implement the Montreal Protocol on Substances that Deplete the Ozone Layer.
