| 摘 要： | 针对济南某办公楼采用如下4种不同自然通风方案后的能耗情况进行模拟分析:①采用空气调节结合自然通风;②加大夜间通风换气次数;③改变通风时段;④改变气候条件。模拟结果表明结合自然通风,全年累计可减少冷负荷58.2%;当夜间通风换气次数增大为1.5 n/h时,综合节能效果最好;选择2:00-7:00时作为通风时段进行自然通风,通风效率最高,能耗费用最低;对于昼夜温差比较大的地区采用自然通风的节能方案最可行。

| Abstract: | The energy consumption of an office building in Jinan is measured and analyzed with the following four ventilation strategies,including compounding the air conditioning systems with natural ventilation,increasing ventilation rate at night,changing ventilation period and changing climate conditions.The results show that the conditioning system with natural ventilation can reduce cooling load 58.2% throughout the year,and the building is the most energy efficient at night when ventilation rate increases to 1.... |
