The fluorinated olefin R-1234ze(Z) as a high-temperature heat pumping refrigerant
Estimates are provided for R-1234ze(Z) of its: (1) critical temperature, pressure, and density, acentric factor, and ideal gas specific heat at constant pressure, and (2) various thermodynamic and transport properties, which are used to predict the performance potential of R-1234ze(Z) in high-temper...

Summary: | Estimates are provided for R-1234ze(Z) of its: (1) critical temperature, pressure, and density, acentric factor, and ideal gas specific heat at constant pressure, and (2) various thermodynamic and transport properties, which are used to predict the performance potential of R-1234ze(Z) in high-temperature heat pumping applications. In particular, for an idealized cycle, the coefficient of performance and volumetric heating capacity for R-114 are 3.24 and 1667
kW
m
−3, respectively, and for R-1234ze(Z) are 3.40 and 1645
kW
m
−3, respectively. The attractiveness of R-1234ze(Z) is confirmed further through heat exchanger simulations. This paper demonstrates that R-1234ze(Z) deserves further consideration as a possible R-114 replacement. |
