7、调室外计算相对湿度45﹪夏季空调室外平均风速2.8m/s冬季空调室外平均风速2.8m/s夏季大气压力997.3hPa冬季大气压力101.9hPa1.3冷负荷本建筑物的总建筑面积为12500㎡，根据《空气调节技术》书中《国内部分建筑空调冷负荷指标的统计值》查的：办公楼的冷负荷指标（W／㎡）：90-140W／㎡。《国内部分建筑空调冷负荷指标的统计值》中注明：当建筑物的总建筑面积在小于5000㎡取上限值，大于10000㎡时，取下限值。按建筑空调冷负荷指标确定的冷负荷即是制冷剂容量，不必再加系数。由于本建筑物的总建筑面积为8000㎡，所以，在此我们选用90W／

8、㎡。则：本设计用户的空调冷负荷：Q=1125kW。1.4建筑资料本设计的制冷站设在底层地下室内
