Derived thermodynamic design data for rankine power cycle systems operating on R142b

Theoretical Rankine power cycle efficiencies ν_R and the (PR) have been presented for Rankine power cycles operating on R142b. These values are listed in tabular form for temperature drops of 5–75°C and for boiler temperatures 25–125°C in 5°C increments. A composite graph showing the relationship between ν_R, T_BO, (PR) and temperature drop (T_BO − T_CO) illustrates the feasible operating range for R142b power cycle systems. The derived thermodynamic data can be used for the rapid preliminary design of the Rankine power cycle systems operating on R142b.
