ABSTRAK
Penelitian ini bertujuan untuk mendapatkan data performa penggunaan refrigerant hidrokarbon MC 134 pada refrigerator dengan tube in tube heat exchanger. Pengujian dilakukan pada temperatur beban pendinginan diatur mulai 60C sampai dengan -60C. Hasil penelitian menunjukkan bahwa penggunaan refrigerant hidrokarbon menghasilkan performa refrigerator yang baik. Semakin rendah temperatur beban pendinginan, maka efek refrigerasi yang dihasilkan meningkat sebesar 3,39%, laju aliran massa refrigerant berkurang 3,28%, daya kompresor berkurang 7,74% dan CoP meningkat 8,39%.

Kata kunci: Hidrokarbon, performa, refrigerant, refrigerator.


ABSTRACT
This study aimed to obtain performance data using a hydrocarbon refrigerant MC 134 on the refrigerator with a tube in tube heat exchanger. Tests performed on cooling load temperature regulated from 60C to -60C. The results showed that the use of hydrocarbon refrigerants produce good performance of refrigerator. The lower the temperature of the cooling load, the refrigerating effect increased by 3.39%, Refrigerant mass flow rate was reduced 3.28%, horse power of compressor reduced 7.74% and CoP increased 8.39%.

Keywords: hydrocarbon, performance, refrigerant, refrigerator.
