Abstract

This study examines the performance of split-type air conditioning with a cooling capacity of 1 PK after replacing a less environmentally friendly refrigerant with a more environmentally friendly one, ranging from R32 to R1270. R1270 has a mass of 50%. The evaporator's inlet temperatures are 23°C, 25°C, and 27°C, while the condenser's inlet temperatures are 30°C and 35°C. The results showed that there was a 41.47 percent decrease in power consumption from R32 to R1270 for cooling capacity, and a 45.46 percent decrease from R32 to R1270 for heating capacity. From R32 to R1270, the COP value decreased by 19.04 percent. R32 still outperforms R1270 in terms of performance, but R1270 has lower power consumption, making electricity consumption more efficient.
