Analisis Performansi Sistem Water Chiller Setelah Proses Retrofit R22 menjadi R290 dengan Variasi Massa Pengisian R290

Prosiding Industrial Research Workshop and National Seminar
Hidrokarbon merupakan refrigeran alami yang memiliki dampak lingkungan yang jauh lebih rendah dibandingkan refrigeran hydrochlorofluorocarbons (HCFC) dan hydrofluorocarbon (HFC). Penggunaan R290 sebagai refrigeran alternatif dan ramah lingkungan dilakukan karena memiliki nilai ozone depletion potential (ODP) nol dan global warming potential (GWP) yang ...
