Abstract

The refrigeration machine is one of the cooling machines whose use is very massive in the industrial sector and in the household sector, both for cooling and for air conditioning systems. In this research study, an experiment was conducted and tested on a refrigerator machine test equipment using R-134a refrigerant varying in mass by 500, 600, and 700 grams to determine the effect of an increase in refrigerant mass on the performance of a refrigerator machine, namely: the effect of refrigeration (cooling effect), the best release of heat, compression work and mass of the refrigerant to produce the highest coefficient of performance (cop) with the thermodynamic simulation calculation method. The calculation results are described in the form of a comparison graph and the results of thermodynamic simulation calculations show effective mass variations for the performance of a refrigerator machine that is at a mass of 700 grams. By obtaining the results of the refrigeration effect (cooling effect) of 145 kJ / kg, the release of heat by the condenser is 170 kJ / kg, compression work 17.5 kW and cop (coefisient of performance) get maximum results of 5.80. Keywords: Refrigerant R-134a, mass variation, refrigerator machine performance Mesin refrigerasi merupakan salah satu mesin pendingin yang penggunaannya sangat masif di sektor industri maupun di sektor rumah tangga, baik untuk keperluan pendinginan maupun untuk sistem pengkondisian udara. Dalam kajian penelitian ini, dilakukan suatu eksperimentasi serta pengujian pada alat uji mesin refrigerator dengan menggunakan refrigerant R-134a bervariasi massa 500, 600, dan 700 gram untuk mengetahui pengaruh kenaikan massa refrigeran terhadap unjuk kerja mesin refrigerator yaitu: efek refrigerasi (efek pendinginan), pelepasan kalor, kerja kompresi dan massa refrigeran yang paling baik untuk menghasilkan koefisien prestasi (cop) yang tertinggi dengan metode perhitungan simulasi termodinamika. Hasil perhitungan dijabarkan dalam bentuk grafik perbandingan dan hasil perhitungan simulasi termodinamika menunjukan variasi massa yang efektif untuk unjuk kerja mesin refrigerator yaitu pada massa 700 gram. Dengan memperoleh hasil efek refrigerasi (efek pendinginan) sebesar 145 kJ/kg, pelepasan kalor oleh kondensor sebesar 170 kJ/kg, kerja kompresi 17,5 kW dan cop (coefisient of performance) mendapatkan hasil yang maksimum sebesar 5,80. Kata kunci: Refrigeran R-134a, variasi massa, unjuk kerja mesin refrigerator
