Abstract

ABSTRAK  Salah satu penentu pada kinerja mesin kompresi uap ditentukan adalah massa refrigeran. Kinerja mesin refrigerasi dapat dinilai pada kondisi kerja sistem meliputi temperature kotak pendingin, temperature kerja kondensor dan evaporator, tekanan kerja kondensor dan evaporator, dan daya kompresor pada variasi massa refrigeran yang ditetapkan. Untuk menganalisa kondisi kerja tersebut mesin refrigerasi kompresi uap diisi menggunakan refrigeran HCR-134a dengan variasi massa 60-220 gram. Hasil pengujian menunjukkan bahwa untuk seluruh variasi massa refrigeran, temperatur kotak pendingin dapat turun terhadap waktu operasi dimana rata-rata penurunan temperatur adalah 7 ºC. Tekanan evaporator dan tekanan kondensor meningkat dengan meningkatnya jumlah massa refrigeran yang dimasukkan kedalam system, mengakibatkan semakin meningkatnya  kerja kompresor. Kenaikan daya kompresor setiap massa refrigeran rata-rata sebesar 0,016 kW.  Kata kunci : Mesin refrigerasi, kondisi kerja, massa refrigeran   ABSTRACT One of the determinants of the performance of vapor compression machine is refrigerant mass. The performance of refrigeration machine can be assessed on the working conditions of the system including temperature of cooling box, evaporator and condenser  temperature, evaporator and condenser pressure, and compressor power at the specified refrigerant mass variations. To analyze the working conditions, the vapor compression machine was filled by HCR-134a with a mass variation of 20-220 gram. The result showed that for all refrigerant mass variations, the temperature of the cooling box decrease with the operating time with the average temperature drop is 7ºC. The evaporator pressure and condenser pressure increase with the increase in the mass of refrigerant introduced into the system, resulting in increased of compressor work. In average, the increase in compressor power for each mass of refrigerant is 0.016 kW. Keywords : Refrigeration machine, working conditions, refrigerant mass

Abstract

An energy saving and sustainable environmental become an attention of the world nowdays. Replacement of halocarbon refrigerant to hydrocarbon give positive impact to the environment because hydrocarbon is friendly refrigeran for environment with low GWP (Global Warming Potensial and zero ODP (Ozon Depleting Potensial). With the replacement refrigerant, it will cause a change performance on refrigeration machine. This study was conducted to determine the effect of hydrocarbon refrigerants with mass amounts of 60 grams on the performance refrigeration machine. The method used in this study was an experimental method to perform the replacement of halocarbons into a hydrocarbon refrigerant with mass amounts of hydrocarbon refrigerants of 60 grams. The results of the study of refrigerant hydrocarbon with mass amounts of 60 grams was found that the required electrical power for compressor of 0.14 kW, power of cooling of 0.73 kW, the heating power of 0.94 kW, and Coefficient Of Performance of 5.21.Keywords: Refrigeration Machine, Refrigerant Mass, Performance, Hydrocarbon Refrigerants
