新风供冷在南京某剧场建筑中的应用

Outdoor air cooling application to a theatre building in Nanjing

介绍了新风供冷量计算方法,得到该项目采用新风供冷的全年可用时间达3 226h,超过了项目运营时间的一半;其节能率达到21%,每年节省用电约140万kW·h。对影响新风供冷的因素进行了分析,提出新风供冷时应尽量提高室内空气标准和全空气系统的最大新风比。

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 building＇s 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 all-air air conditioning system when applying outdoor air to free cooling.
