ANALISIS VARIASI MEDIA PENDINGIN KONDENSOR TERHADAP RASIO PELEPASAN KALOR DAN COEFISIEN OF PERFORMANCE (COP) PADA MESIN PENDINGIN
ABSTRACT: Household
refrigerating machine (refrigerator) is a household appliance that is widely
used in the family in Indonesia. The condenser is one of the essential
components of the refrigerator that functions as a heat exchanger which is
composed of the equivalent gas-phase refrigerant into a liquid. A crucial
element of the condenser to cool the evaporator with the faster is the rate of
heat release, coefisien of performance (COP). This research was conducted by
varying the experimental cooling medium in the condenser of household
refrigerating machine (refrigerator), such as the natural air cooling medium,
the addition of fins and additional fan area 14,4 Watt. It aims to improve the
coefficient of achievement refrigeration, heat release ratio and cooling rate
speed. The results showed a coolant condenser with fan 14.4 W produces the
highest COP value, 4,73, and the ratio ofthe smallest heat release ratio, 1,2.
The larger the COP and the smaller pelepasn calorific value, indicating that
the machine work better.
