Research on the Flammability Limits of R1234yf/R290 and R1234ze(E)/R290 Mixtures

open access: yesZhileng xuebao
Propane (R290) is a potential refrigerant substitute for household air conditioners. However, its flammability limits its application. In this study, the flammability limits of R290, 2,3,3,3-tetrafluoropropene (R1234yf), trans-1,3,3,3-tetrafluoropropene (

Thermal Conductivity Measurements for trans-1,3,3,3-Tetrafluoropropene (R1234ze(E)) in Liquid Phase

open access: yes, 2022
Refrigeration, heat pumps and air conditioning sectors are under pressure to find low GWP working fluids suitable for the substitution of the current high GWP refrigerants, as required by the European Regulation EU No 517/2014. Halogenated olefins (HFOs and HCFOs) are the most promising group of synthetic compounds being considered for such purpose ...
