Boiling Heat Transfer Coefficients of R290 in Tubes
Journal of Physics: Conference Series, 2023 Abstract In 2016, Montreal Protocol Kigali Amendment stipulated that developed countries should reduce the consumption and production of HFCs from 2019 and that developing countries should start the reduction in 2029. New alternative refrigerants should have lower GWP to reduce negative effects on the environment.

Thermodynamic screening of alternative refrigerants for R290 and R600a
Results in Engineering, 2020 Due to Regulation EU 517/2014 (F-Gas), the use of refrigerants with GWP higher than 150 was limited from 2015 on in small capacity refrigeration systems in Europe. Although refrigerants that dominate are R600a and R290 nowadays, which are classified as A3 by ASHRAE 34, literature points out that some refrigerant mixtures exist that could offer benefits
