Measurements of saturation pressures for the novel refrigerant R1132(E)

• R1132(E) is a promising next-generation refrigerant with zero ODP and very low GWP. saturation pressures were measured between 240 K to the critical temperature. The pressure of was directly as 5172.5 ± 1.0 kPa. A Wagner-type equation optimized for pressures. acentric factor determined used in Peng-Robinson EoS. (trans-1,2-difluoroethylene, C 2 H F ) potential next generation be utilized air conditioning applications. This hydrofluoroolefin (HFO) possesses an extremely low-GWP value below 1 it excellent candidate replacing R32 blends such R410A, which are subjected local international greenhouse gas regulations limiting global warming. Two isochoric apparatus measure from its At temperature, also measured. Twenty-four including point optimizing representing curve. absolute average deviation predicted by model using fitted parameters experimental data 0.02%. determining 0.2433, further prediction cubic state within 0.31%.
