Abstract EN
Due to the environment depletion, replacing chlorofluorocarbons in refrigeration industry was an important problem.
in the experimental study a (1.0 tr) vapor compression system were used with original working fluid of r-22 and compared to alternatives refrigerant r-407c and r-22.
the effects of the main parameters of performance analysis such as refrigerant type, compressor pressure ratio, outlet air evaporative temperature, coefficient of performance were investigated for various ambient temperatures above 50 ºc.
the results showed that the compressor ratio of system using r404 and r-407c is more than the compressor ratio of system using r22 by 2% and 4% respectively.
also, the outlet air evaporative temperature of system using the alternative refrigerant r-22 is more than the outlet air evaporative temperature with system using r-407c and r-404 by 8% and 5% respectively.
the coefficient of performance of r-407c was measured with the same reciprocating compressor that was supplied with the r-22 system.
it could be concluded that there is a decrease of 8% in system cop as friendly environment r407c compared with system using r-22 and a decrease of 12% in system cop when using r-404.
however; the result showed that r407c have thermodynamic performance similar to r-22.
engineering equation solver (ees) software is used for draw (p-h) diagram for the cycle.
