为了估算现有办公楼混合空调系统的年度运行效果和节能效果，进行了现场测量和热气流网络分析。获得以下结果： 1) 根据年度运行中的测量值分析显示混合空调系统的性能。 2）2012年总自然通风量为352.2×105 m3（平均换气次数为2×4次/h）。 3）根据BEMS数据分析，显示各条件对自然通风的贡献率。 4）自然通风率的计算误差约为6.6%，因此所提出的计算模型具有足够的预测精度。 5) 在此分析中，2012 年混合空调系统的年节能效果约为 6.1%。 6) 使用所提出的计算模型通过案例研究阐明了改善操作的量化效果。
In order to estimate of annual operation results and energy saving effect of a hybrid air-conditioning system in an existing office building, field measurements and thermal and air-flow network analyses were carried out. The following results were obtained : 1) The behavior of the hybrid air-conditioning system was shown based on analyses of measured values within annual operation. 2) The total natural ventilation rate in 2012 was 352.2 105 m3(The average of air change rate was 2 4 times/h). 3) The contribution ratios of each conditions for natural ventilation were shown based on the analyses of BEMS data. 4) The calculation error of natural ventilation rate was about 6.6%, and so the proposed calculation model had sufficient prediction accuracy. 5) In this analysis, the annual energy saving effect of a hybrid air-conditioning system was about 6.1% in 2012. 6) The quantitative effect by improving the operation was clarified by case studies using proposed calculation model.
