<![CDATA[In the condenser pipe a process of heat transfer from the refrigerant vapor to the air conditioner, the amount of heat transferred through the wall of the cooling pipe depending on the temperature difference, the pipe material, the flow rate of refrigerant and cooling fan. Condenser fan motor used as a driving force to rotate the fan to circulate cold air to cool the condenser. Therefore the condenser fan rotation greatly affect the performance of the condenser in heat transfer. In this experiment will examine how large the influence of the condenser fan rotation on the rate of cooling and the resulting COP. Experimental method is carried out by variation of the condenser fan rotation, namely: 700 rpm, 800 rpm, 900 rpm, 1000 rpm and 1100 rpm. Having done the research and analysis of data on round fan condenser 700 rpm, 800 rpm, 900 rpm, 1000 rpm and 1100 rpm, be concluded that the round fan condenser most optimal is the rotation of 900 rpm, as shown by the results of the cooling rate of the fastest and the COP compared with the variation of the condenser fan rotation others. The cooling rate generated in the condenser fan rotation rpm 900 reaches -3.6 ⁰C in the first 5 minutes and reach the steady state in the 15th minute with a temperature of 23.2 ⁰C and COP at 14.33.]]>
