Chiller manufacturers are facing a Jan. 1, 2024, implementation date to phase out the use of hydrofluorocarbons (HFCs) R-134a, R-410A, and R-407C in new liquid chillers, despite Air-Conditioning, Heating, and Refrigeration Institute's (AHRI's) efforts to change the proposed effective date...
The Montreal Protocol of 1987 led to the phase-out of ozone depletion gaseous, and R-410A and R-407C were developed to replace ozone depletion refrigerants like R22. Since Difluoromethane makes up a significant portion of both R-410A and R-407C, it's widely available in the market. ...
R-404A began seeing usage in 1996 after the phase out of CFC R-502 due to it's Ozone Depletion Potential. R-404A is a ternary refrigerant blend consisting of the HFC R-125 (forty-four percent), HFC R-143a (fifty-two percent), and HFC R-134a (fou...

Hydrofluorocarbons' (HFCs) usage in cooling equipment and subsequent emissions are expected to increase dramatically in India with the phase-out of hydrochlorofluorocarbons (HCFCs) as coolants in air-conditioning equipment. We focus on the residential air-conditioning sector in India and analyse a ...
The world community has committed to eliminate the HCFC-22 refrigerant to a series of deadlines according to the agreements taken during the 19th Montreal Protocol meeting in September 2007. This phase-out, which is already in progress in European Countries, has been accelerated in Article 5 count...
