Latest Patents

Guangming Chen holds a patent for an environmentally friendly alternative refrigerant for HCFC-22. This invention discloses ternary mixtures of fluoroethane (HFC-161), pentafluoroethane (HFC-125), and difluoromethane (HFC-32) as substitutes for HCFC-22. The mass ratios of the mixture components are 5-60%, 25-50%, and 5-50%, respectively. Notably, this refrigerant has an Ozone Depletion Potential (ODP) of zero, indicating no harmful effects on the ozone layer. Additionally, its Global Warming Potential (GWP) is lower than that of HCFC-22, R407C, and R410A. The working pressure and pressure ratio of this alternative are comparable to those of HCFC-22, allowing for minimal changes to existing system components for its implementation.
