在许多领域的计算与应用中，常需借助室外干球温度的逐时资料。
The data of hourly outside dry-bulb temperature are often needed in the calculations and applications of many areas.
但是，对于常年全负荷运行的发电设备而言，如果机房内是采用通风换气降温时，不能错误的采用夏季室外通风计算温度。
But for full load generating equipments all year round, outdoor design temperature for summer ventilation is not suitable for room ventilation cooling.
