Résumé

This article is the Spanish translation of an article presented at the 12th International Refrigeration and Air Conditioning Conference, Purdue University, USA (see the Bulletin of the IIR, reference 2009-1783). In this study, thermodynamic performance of R432A and HCFC-22 is measured in a heat pump bench tester under both air conditioning and heat pumping conditions. R432A has no ozone depletion potential and very low greenhouse warming potential of less than 5. R432A also offers a similar vapour pressure to that of HCFC-22 for 'drop-in' replacement. Test results showed that the coefficient of performance and capacity of R432A are 8.5-8.7 and 1.9-6.4% higher than those of HCFC-22 for both conditions. The compressor discharge temperature of R432A is 14.1-17.3°C lower than that of HCFC-22 while the amount of charge for R432A is 50% lower than that of HCFC-22 due to its low density. Overall, R432A is a good long term 'drop-in' environmentally friendly alternative to replace HCFC-22 in residential air conditioners and heat pumps due to its excellent thermodynamic and environmental properties.
