ABSTRACT
The cooling process s essentially a process of transfer of heat energy contained in a room. This study aims to determine the effect the rotating speed of the compressor driving machine on the optimum cabn optimm time temperature of the tropics. Equipment used in this research is panel of electrical system of conditioner.the research method is done way of experiment directly on the tool with the speed parameters of the engine speed of the compressor with the temperature to be achieved 20 oC, 22 oC, 24 oC,dan 26 oC. The results showed that the higher the compressor turn speed the shorter the time required to cool the cabin. At the engine speed of 1500 rpm. Cp = 290,07 J/mol.K, W = 0,02542 m, top = 0,00219 hours. At 2000 rpm engine speed, Cp = 234,48 J/mol.K, W = 0,0285 m, top = 0,00220 hours. At 2500 rpm engine speed, Cp = 175,88 J/mol.K, W = 0,03303 m, top = 0,00222 hours. At 3000 rpm engine speed, Cp = 117,275 J/mol.K, W = 0,04059 m, top =0,00223 hours. At the speed of 3000 rpm compressor engine speed obtained the actual time of the shortest tact = 2.073 minutes and the optimum time top = 0.00223 hours.
