Résumé

HCFC-22, widely used in room air conditioners, has to be phased out by 2030 under the Montreal Protocol. HC-290 is being considered as alternative to HCFC-22. A 5.13 kW capacity split air conditioner designed for HCFC-22 was considered. After establishing the baseline performance data with HCFC-22, the unit was retrofitted with HC-290. Under the drop-in test, the cooling capacity with HC-290 was lower by 6% and COP higher by 14%. The optimized charge of HC-290 was about 50% of HCFC-22 by weight. A 30% larger condenser gave 1.6% lower capacity and 10% higher COP. With a 10% higher capacity compressor, the cooling capacity was improved by 2.8% and COP was lower by 1.1%. In the case of 10% higher capacity compressor and 14.7% longer capillary, the cooling capacity was 5.2% higher with 2.9% lower COP. ORNL Heat Pump Design Model was used to predict the performance of the systems with HC-290 and to optimize the system.
