| Summary: | The present study aims to investigate the effect of changing air condi-
tioning refrigerants and compressor lubricants on system performance. Two types of
refrigerants namely R410a and R32 paired with two different lubricants were inves-
tigated. A test rig consists of residential air conditioning with a thermal control room
was developed in the present study. The initial refrigerant charge was varied to deter-
mine the optimum charge for each refrigerant-lubricant mixture. The results reveal
that the optimum charge for R32 is 350 g that represents only 70% of the refrigerant
amount for R410a. R32 performs better than R410a for both lubricants mixture. The
R32-POE combination shows the best performance with 14% improvement from the
baseline data. R32 performs better in the air conditioning originally design for R410
refrigerant and has a good prospect to replace R410a as a more environmentally
friendly refrigerant. |
