Résumé

The environmental concerns with the impact of refrigerant emissions lead to the importance in identifying a long-term alternative to meet all requirements in respect of system performance and service. Even though HFC-134a and HC blend (containing 55.2% HC600a and 44.8% HC-290 by weight) have been reported to be substitutes for CFC-12, they have their own drawbacks in respect of energy efficiency/flammability/serviceability aspects of the system. In this present work, experimental investigation has been carried out on the performance of an ozone friendly refrigerant mixture (containing HFC-134a/HC blend) in two low temperature systems (a 165 l domestic refrigerator and a 400 l deep freezer) and two medium temperature systems [a 165 l vending machine (visi cooler) and a 3.5 kW walk-in cooler]. The oil miscibility of the new mixture with mineral oil was also studied and found to be good. The HFC-134a/HC blend mixture that contains 9% HC blend (by weight) has better performance resulting in 10-30 and 5-15% less energy consumption (than CFC-12) in medium and low temperature system, respectively.
