THEORETICAL PERFORMANCE OF HCFC123 AS AN ALTERNATIVE TO CFC11

Based on the thermodynamic properties of HCFC123 obtained by using a m odified Benedict-Webb-Rubin (MBWR) equation of state fit to experiment al measurements, the theoretical performance of HCFC123 has been asses sed as an alternative to CFC11 by using standard refrigeration paramet ers, including pressure ratio, specific compressor displacement, coeff icient of performance, and shaft power. This study indicates that a CF C11 compressor working with HCFC123 will have lower adiabatic head ris e, efficiency and volume flow. This performance difference should not exclude HCFC123 as an alternative to CFC11 since most of the existing machines are oversized for a particular application and thus performan ce attained with HCFC123 could be adequate.
