An experimental performance study on vapour compression
refrigeration system with R134a and drop in substitute R152a
with aluminium microchannel condenser was carried out for
condensation temperature of 48°C while evaporation
temperature varied from -10 to 15°C. Refrigerant charge of
R152a was reduced by 40% over R134a with the microchannel
condenser. Performance parameters like work input to the
compressor, coefficient of performance, refrigerating capacity,
condenser capacity and the product of the overall heat transfer
coefficient & surface area of the condenser are plotted and
results are discussed.
