摘要(Abstract):

对香港地区某办公建筑变风量(VAV)空调系统控制方法进行改造,在冬季及夏季分别选取两天,现场分别采用定静压定送风温度控制方法和改造后的变静压变送风温度控制方法进行测试。比较了两种控制方法下系统的运行情况。引入输送系数评价节能效果,采用ADPI值评价室内热舒适性。结果表明,采用变静压变送风温度控制方法后室内热舒适性得到明显提高,且变静压变送风温度控制方法在部分负荷下节能效果较为明显。
The control method of variable air volume(VAV) system in an office building in Hong Kong was transformed.Two typical days in the winter and summer were selected,respectively.The performance of the duct static pressure reset control & supply air temperature reset control and constant duct static pressure control & constant air temperature control method was tested in an existing office building in Hong Kong.The operations of the system with two control methods are compared.Coefficient of transformation is introduced to evaluate the energy saving effect.ADPI is adopted to evaluate the indoor thermal comfort.Results show that the indoor thermal comfort is improved apparently when the duct static pressure reset control is adopted.Duct static pressure reset control & supply air temperature reset control at part load energy saving effect is more obvious.
