Second and third virial coefficients for the R41+N2O system
Fluid Phase Equilibria, 2004Abstract As a part of our ongoing research program on the PVTx measurements by the Burnett method for HFC + hydrocarbon and/or inorganic compound systems, in this work the experimental results for the nitrous oxide (N2O) + fluoromethane (R41) system will be described. The system was chosen as an alternative refrigerant mixture.

Abstract In this study, blend of CO2 with R41 is evaluated for application in three different systems including a refrigerated cabinet, an air-source heat pump water heater and a water-source heat pump water heater. The effects of CO2/R41 mixture as an azeotropy refrigerant on system performance are analyzed under various working conditions.

Investigation on the environmental impact of R32, R152a and R41 refrigerant blends
Engineering Research Express, 2023Abstract The improper usage of refrigerants has a drastic impact on the environment, which is contributing to global warming and ozone layer depletion. The refrigerants which are being used currently have a very high GWP (Global Warming Potential) value that signifies an adverse impact on global warming.
