Stratospheric ozone depletion and global temperature elevation resulting from the discharge of refrigerants from conventional cooling systems have demonstrated to be a menace to animal kingdom around the globe. International pacts viz. Montreal and Kyoto Protocols were designed and enforced on technologically developed and developing countries to restrain the manufacture and consumption of these halogen-laden man-made working mediums bearing significant Ozone depleting potential (ODP) and Global warming potential (GWP), followed by phasing out the relative impact of these climate gases out entirely as early as possible. In response to the Kigali agreement to the Montreal Protocol, momentous researches are being carried out across the globe with a compulsion to find green refrigerants proficiently operating in innovative refrigeration techniques in meeting the growing demands, harmonizing the paradigm shift. This paper authenticates the hitches related to the orthodox halogenated entrants and critically reviews the reported literatures in the past few decades for the choice of credible substitutes considering environmental, economic and energy competent aspects. The present review emphasizes on the feasibility of the most suitable long term surrogate for the cooling system based on the thermo-physical properties of various refrigerants.
