Analysis of Savings on Electricity Consumption in Room Air Conditioning by Using R1270 (Propylene) Refrigerant Instead of R32 capacity of 13,000 Btuh Widodo, Fatkur Rachmanu, Ade Irvan Tauvana Journal of Physics Conference Series, 2020 Global Warming Potential (GWP) is a serious problem whose impact can affect the stability of the atmospheric environment, Refrigerant R-32 (Difluoromethana) contains GWP: 675 but does not contain ODP (Ozone Depleting Potential) while R1270 (Propylene) refrigerant is non-ODP and have GWP: <4. The equipment used in the study was a prototype of a split air conditioner cooling machine for a work room with a cooling capacity of 13,000 Btuh. Methodology by testing the performance of the R32 AC-Split unit according to the 850gram refrigerant mass nameplate at suction pressure: 115 Psig while R-1270 with the refrigerant mass: 300 gram at suction pressure: 90 Psig. The test is carried out until the temperature reaches a stable with an operating time: 90 minutes. From the results of tests and analysis of calculations performed, obtained an average air temperature of the evaporator R- 32/R1270: 19.1°/19.2°C, cooling effect: 267.9/336.7, compression work: 89.3/80.16, COP: 3.0/4.2, refrigerant mass:850/300gram and electric current: 3.5/2.4 Ampere. Savings in refrigerant and electricity consumption reached 31.4%.
