Theoretical and experimental study on a novel mixture refrigerant of R161+R227ea

R161 with excellent cycle performance was employed as the main component and R227ea was introduced as an antiflaming component. A new refrigerant with good cycle performance and safety performance was found to replace the traditional refrigerant R22 by optimizing the composition of R161 and R227ea based on the principle of complementary advantages.A program combined with REFPROP 7.0 was wrote to calculate the thermodynamic property and cycle performance.The cycle performances of R161+R227ea and R407C were conducted on the electric calorimeter apparatus.The theoretical and experimental analysis show that the refrigerating capacity and power consumption of the new refrigerant is lower than R407C,while the coefficient of performance(COP) is equal to R407C and the discharge temperature is about 5 ℃ lower than R407C.The novel mixture refrigerant has the potential to replace R407C and R22.
