Özet
In this study, the TEWI values for R417A and R424A refrigerants instead of HCFC-22 gas which don't deplete ozone layer were calculated and then compared. For a split type air conditioning equipment, the energy consumption amounts were experimentally determined for the three different refrigerants at an average ambient temperature of 38 degrees C. The annual energy consumption that is the cooling requirement was evaluated for the specific operating hours in May-September period. As a result of calculations, direct impact of R424A with the higher GWP value was also higher. It was found that although energy consumptions for both R424A and R417A were less than that for R22 by 10%, their TEWI values were to be higher with 2 to 4% because of their greater GWP magnitudes.
