Abstract

Performance of Deep Freezer by Using Hydrocarbon Blends as Refrigerants

Author(s): J. Thavamani*, Marripudagala Komali, Shaik Mazharuddin And Kukkadapuradha Krishna Manoj

This paper projects experimental study carried out for evaluating performance parameters of deep freezer when three ratios of Propane [R290] (pure 100%), Iso -butane [R600a] (pure 100%), R600a (50%) + R290 (50%), R600a (20%) + R290 (80%), R600a (80%) + R290 (20%) are used. The purpose of alternative refrigerants has the advantage of being locally available and environment friendly nature. An unmodified deep freezer was charged and tested with each of the five hydrocarbon mixtures that consist of Propane [R290] (pure 100%), Iso -butane [R600a] (pure 100%), R600a (50%) + R290 (50%), R600a (20%) + R290 (80%), R600a (80%) + R290 (20%). The parameters investigated are the evaporator capacity, the pressure ratio, Variation of evaporator temperature with Specific heat, Variation of evaporator temperature with Vapour density, Variation of Evaporator temperature with cop. The present work shows that the propane is most suitable alternative refrigerant to HFC’s with best performance among all other hydrocarbon mixtures investigated. When propane was used the evaporator temperature reached -20oC with COP of 3.43 at condenser temperature of 27oC as compared to COP of 2.75 for the R600a (20%) + R290 (80%) refrigerant at the same temperature.
