		abstract={Refrigerant use with various types have been increasingly used by the public, because the benefits of the refrigerant is very much at its main benefits is environmentally friendly. But in practice, people only use the refrigerant in the cooling machine. In this research, testing analysis on the cooling machine using the comparison of different types of refrigerant subcooling by adding to the engine coolant circuit. mixture of two refrigerants in use are R290 (hydrocarbon) and R404a (HFC) .Penelitian using the experimental method to get the real bertujan COP (coefisien Of Performance) engine cooling is better than one refrigerant that is in use. In this study, the level of subcooling varied on the load that is given in the form of incandescent light bulbs of course with varying power as well.}
