Abstract：
Presents the calculation method for outdoor air cooling capacity, and concludes that the annual utilization hours for outdoor air cooling can reach 3 226 hours, which exceeds a half of the buildings operation time in one year. The yearly energy saving ratio of outdoor air cooling is 21%, which can save electricity consumption about 1 400 000 kWh. Analyses the factors influencing outdoor air cooling and suggests that, in order to increase energy saving ratio, it should enhance indoor air standard and maximize outdoor air ratio of allair air conditioning system when applying outdoor air to free cooling.
