“…Refrigeran hidrokarbon seperti R290 memiliki density yang kecil dibanding refrigeran jenis sintetik R32 yang berdampak pada pengisian lebih kecil jumlahnya jika dibanding R32 ± 30% dengan volume yang sama R290 memiliki LFL yang lebih kecil yang dapat berpotensi menyebabkan terjadinya kebakaran pada batasan tertentu (Colbourne dan Suen, 2021). R290 (propane) refrigeran jenis alamiah memiliki massa jenis lebih rendah dan dapat menurunkan konsumsi listrik sampai dengan 31,4% terhadap R32 hasil ini dapat membantu untuk melakukan pengembangan dengan refrigeran sejenis dari bahan bakunya antara propane dengan propylene (Widodo, Rachmanu dan Tauvana, 2020).…”

R290 is a type of natural refrigerant that has ODP = 0 and GWP = 4. While R32 from synthetic materials has ODP= 0 and GWP = 675 both are refrigerants used in Split AC. With this high GWP, it can have a damaging impact on the atmosphere. The advantage of R290 is that it has a lower density compared to R32, which can save the number of fillings in the AC unit by ±30% of the previous amount of refrigerant in the same volume. R290/R32 was flammable with LFL= 2%/13% and UFL= 10%/33%. The purpose of this study was to analyze the performance of R290 as a substitute for R32 on an AC-split unit with a capacity of 9,000 Btuh/hr. The steps used in the test are that the AC unit is placed in an open room with ambient temperature around 32°/80°C. The test was carried out until it reaches the optimal and stable temperature, then data is collected. The results of data collection from the evaporator air temperature R290/R32 = 21.4°C/23.0°C, condenser air temperature = R290/R32= 35°C/38.5°C, suction pressure= 90 psig/130 psig and discharge 200 psig/420 psig. The test data were analyzed and calculated using the Mollier Chart software with the results = R290/R32 = refrigeration effect = 344.8/272.2 kJ/kg, compression work = 12.18/13.02 kJ/kg, COP = 28.3/20.9, compression ratio = 2.2/3.2, strong electric current 4.98/5.73 A. From the decrease in electric current of R290 obtained a savings of 13.3% was obtained when converted to electricity bill payment and get a profit of 45,886/month.

The problem of global warming or called GWP (Global Warming Potential) that occurs in the earth’s atmosphere, one of which comes from synthetic refrigerants used in household air-conditioning refrigeration machines. R410A is a refrigerant that still contains GWP: 1942. Hydrocarbon refrigerant is a refrigerant that does not contain ODP (Ozone Depleting Potential) and a very small GWP. By using ref prop software, the mixing process can be simulated to obtain refrigerants that have characteristics similar to R410A. Mixing using R32 / R290 ingredients varied with percentage compositions ranging from 50/50, 40/60, 30/70, 20/80, and 10/90. From the simulation results, a mixture approaching R410A with 10/90 composition with COP: 3.85 for R410A and 5.76 for 10/90 mixture was obtained. Compression ratio: R410A: 2.8 and for mixed refrigerants 10/90: 1.8. The refrigerant effect of mixed refrigerants is 10/90: 264,13, R410A: 161,68. By using this refrigerant mixture can reduce the GWP and improve the performance of the Air Conditioning cooling system so that it has a reduced GWP value that can be obtained significantly and has a large enough potential to replace the R410A.
