UJI EKSPERIMENTAL MESIN PENDINGIN BERPENDINGIN UDARA, DENGAN MENGGUNAKAN REFRIGERAN R22 DAN REFRIGERAN R407C
Abstract: Refrigerant R22 can
cause ozone layer depletion so that required refrigerant substitute for R22. Refrigerant
R407C is one of the refrigerant substitute for R22. Research of refrigerant in
the cooling engine with air-cooled condenser is done by experimental methods.
This research was conducted usingrefrigerants R22 and refrigerant R407C with a
flow rate of 20 L /h, 40 L/h, 80 L/h and 120 L/h. Test dataprocessing include
the calculation of refrigeration capacity, compressor power and COP values. COP
orCoefficient Of Performance shows the efficiency of the refrigerant. The best
COP values are in therefrigerant flow rate of 40 L/h, with R22 COP value of
5.818 and R407C COP value of 4.875.
