| Abstract | ||
| The study presents optimized R432A charge by the index of power consumption of compressor and COP without changing the compressor. Test results showed that the best charge is 750 g for R432A which gave the highest coefficient of performance and less energy consumption. When charging the system with 750 grams, the amount of charge rate down to 42.3% compared with the original gas. The percentage increase in coefficient of performance are 9.85%, 8.39%, and 8.93% and the proportion of low energy consuming are 7.53%, 7.31%, and 7.34% at ambient temperatures of 30 ᵒC,34 ᵒC and 38 ᵒC respectively for R432A compared to R22. Increasing ambient temperature lead to increase in the power consumed and decrease coefficient of performance. | ||
