EXPERIMENTAL PERFORMANCE OF R134a AND R152a USING MICROCHANNEL CONDENSER

Özet

An experimental performance study on vapour compressionrefrigeration system with R134a and drop in substitute R152awith aluminium microchannel condenser was carried out forcondensation temperature of 48°C while evaporationtemperature varied from -10 to 15°C. Refrigerant charge ofR152a was reduced by 40% over R134a with the microchannelcondenser. Performance parameters like work input to thecompressor, coefficient of performance, refrigerating capacity,condenser capacity and the product of the overall heat transfercoefficient & surface area of the condenser are plotted andresults are discussed.
