Abstract: Due to the systems of mechanical vapor compression have a high energy consumption for air-conditioned space. Therefore, the system of evaporative cooling presents as a promising alternative option for the air-conditioning system. Moreover, the pre-cooling system is normally used to reduce an intake ambient air temperature before the air-conditioning system. As mentioned above, this research aims to investigate the effectiveness of evaporative cooling system by using a car radiator for air per-cooling. In this research, the commercial car radiator was used for cooling inlet ambient air by cooling water. The evaporative cooling system consisted of evaporative cooling panel with a maximum water rate of 40 lite/minute and a maximum air rate of 5,100 m3/hr. The results show that most suitable water flow rate of radiator is 10 lite/minute and this radiator can make the differences of air temperature of about 8.9oC. Moreover, the results also show that the effectiveness of evaporative cooling system could reach about 73.31% with a maximum sensible heat of 8.43 kW.
