STUDI EKSPERIMENTAL MESIN REFRIGERASI SIKLUS KOMPRESI UAP MENGGUNAKAN REFRIGERAN HIDROKARBON SUBSTITUSI R22 PADA KONDISI TRANSIENT

ABSTRACT: Halokarbon refrigerant or R22 used in refrigeration systems later revealed potentially damaging the ozone layer, as replacement could be used a hydrocarbon refrigerant, one of which is environmentally friendly HCR22 refrigerant. In this study conducted experimental study of vapor compression refrigeration machine that compares the performance of the engine in transient conditions using hydrocarbon refrigerant substitutes for R22 (HCR22) and the refrigerant halokarbon (R22). The results showed that the use of hydrocarbon refrigerant HCR22 (10.6oC temperature achieved at the time 10 minutes) lower temperature achieved faster than using the R22 (19.8oC temperature achieved at the time 10 minutes). This result is comparable with the resulting COP, COP with HCR22 (3.104 after 50 minutes) is greater than the R22 COP (2.123 after 50 minutes). Compressor power used by HCR22 (0.846 kW after 65 minutes) is smaller than the R22 (0.953 kW after 65 minutes). Can be concluded that the use of hydrocarbon refrigerant to produce cooling low temperature more rapid with a more efficient electrical consumption of compressors.
