Abstract

AbstractType of refrigerant the most recognized and the most used today in the vapor compression cycle is R-12 refrigerant (halocarbon group), which is technically quite good.  The refrigerant also has low toxicity and low flammable. But, in the mid 1970’s known that chlorine has contained in the refrigerant were released into the environment could damage of ozone in the stratosphere and caused greenhouse effect. Because of that, it using has stopped. An alternative refrigerant is hydrocarbon refrigerant (HCR) and one of it is hydrocarbon-12 (HCR-12). HCR-12 have several advantages, besides friendly environmental because have low global warming effect and low destruction of ozone, this type of refrigerator can be used as direct changer on the refrigerant machine so no needed compressor replacement and more efficient electric energy than R-12. In this research, did a study experimental to compared R-12 with HCR-12 with used vapor compression cooler machine. The result of measurement have been get performance of vapor compression cooler machine COPR (Coefficient of Performance Refrigeration) and COPHP (Coefficient of Performance Heat Pump) for R-12 and HCR-12 relatively are 2.4 – 9.8 (COPR) and 3.4 – 10.8 (COPHP) and 6.4 – 14.1(COPR) and 7.4 – 15.1 (COPHP). Performance of vapor compression cooler machine COPR and COPHP have tendency increase with increase rate of flow of refrigerant until 0.035 for R-12 and 0.014 for HCR-12. Performance vapor compression cooler machine of COPR increase if absorbed of heat (Qe) by evaporator increase and COPHP increase if released of heat (Qk) by condenser increase. According of the results concluded that performance of vapor compression cooler machine with hydrocarbon-12 (HCR-12) better than R-12.Key words : refrigerant, hydrocarbon, R-12, ODP, GWP.

Abstract

Modul thermoelectric cooling (TEC) adalah salah satu jenis pompa kalor berbentuk padatan (solid-state) yang membutuhkan penukar kalor untuk membuang kalor sebagai efek Peltier. Termoelektrik dapat memanaskan dan mendinginkan hanya dengan membalikkan polaritas, yang mengubah arah perpindahan kalor. Sisi yang dingin dapat digunakan sebagai pendingin dan sisi yang panas dapat digunakan sebagai pemanas. Penelitian ini bertujuan merancang kotak pendingin dan pemanas yang memanfaatkan modul termoelektrik sebagai sumber kalornya dengan menentukan daya yang dibutuhkan dan pemilihan rancangan terbaik. Tahapan pemilihan rancangan kotak pendingin dan pemanas (cool and hot box) adalah melakukan analisa beban kalor, perbandingan massa, perbandingan daya listrik, dan jumlah modul TEC yang digunakan, untuk menentukan desain optimum kotak pendingin dan pemanas. Hasil rancangan diperoleh ruang kotak pendingin dan pemanas dengan dimensi: 0,26 m x 0,20 m x 0.15 m dengan ketebalan polyurethane foam 25,7 mm sebagai isolator kotak  pendingin, dan ketebalan 15,3 mm untuk isolator box pemanas. Daya yang dibutuhkan untuk mendinginkan minuman selama 30 menit dengan target temperatur ruang pendingin 15 ℃ adalah sebesar 86,07 W
