	abstract = {<p>This paper presents the experimental performance analysis of a 1.5 TR window air-conditioner, retrofitted with R-407C, as a substitute to HCFC-22. Experimental results showed that R-407C, for the operating conditions covered in this study, had lower cooling capacity in the range 2.1-7.9\% with respect to HCFC-22. The coefficient of performance for R-407C was lower in the range 7.9-13.5\%. The power consumption of the unit with R-407C was higher in the range 6-7\% than HCFC-22. The discharge pressures for R-407C were higher in the range 11-13\% than HCFC-22. This paper also presents simulation results of heat exchangers of an HCFC-22 window air conditioner retrofitted with R-407C. The simulation has been carried out using EVAP-COND, a heat exchanger model developed by National Institute of Standards and Technology, U.S.A. The simulated evaporator capacities are within +/- 3\% of the experimentally measured cooling capacities for both refrigerants. Simulation results for R-407C and HCFC-22 are compared. The exit temperatures of R-407C are lower by 1.9 degrees C to 5.2 degrees C in the condenser and are higher by 3.2 degrees C to 3.8 degrees C in the evaporator than HCFC-22. Evaporating pressures of R-407C are higher by 4.5-5.3\% as compared to HCFC-22. The pressure drops of R-407C are lower in both the evaporator and the condenser as compared to HCFC-22. The outlet temperatures of air for HCFC-22 and R-407C in both heat exchangers are nearly the same. (c) 2005 Elsevier Ltd. All rights reserved.</p>},
