The dew point evaporative air conditioning system has gradually become an attractive research area in recent years because of its low energy consumption and environmental friendly advantage. How to improve the system efficiency is the focus of current research. This paper presents the theoretical performance of the dew point evaporation model with or without perforations. The heat and mass transfer model of the dew point evaporative cooling system was established and solved. It was found that the optimal supply air ratio was 0.7–0.8 and the value of the channel height was 4mm–5mm according to the evaluation parameter of the cooling capacity. Compared with other parameters, the supply air ratio has a more significant effect on the performance of the perforated cooling system. Single perforation has the best cooling system performance with supply air ratio of 0.5–0.7. Two perforations is the best for supply air ratio 0.3–0.4, while three perforations is more appropriate when supply air ratio is 0.2.
