This paper discussed the energy-saving effect of intelligent ventilation system in communication base station with measured data. The results showed that the yearly electricity-saving per unit area of base station with intelligent ventilation system distributed in 60

the energy-saving effect was more significantly with lower temperature outside and longer time with low temperature. In central and southern Shaanxi

the operation time of air-conditioning shorten 13%
