6、7℃，回水温度12℃。一．原始资料1.1地点：山东省济南市济南市：北纬36.6°，东经117°，海拔170.3m。1.2室外气象参数夏季室外气象参数冬季室外气象参数夏季空调室外计算干球温度34.8℃冬季空调室外计算干球温度-7.7℃夏季空调室外计算湿球温度27℃冬季空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

7、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／㎡。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。二．确定冷水机组的型号、台数制冷系统机组化是现代制冷装置的发展方向。制冷机组就
