摘    要:对于风机盘管加新风系统中最常见的新风处理方式之一:处理后新风直接送入室内,文章根据冬季新风比确定风机盘管出风状态点和冬季新风处理终态点,给出了冬季空调工况的i-d图设计方法。对于冬季新风处理终参数的选取,给出3种情况:冬季新风处理至室内焓值;冬季新风处理至室内焓线和等温线之间;冬季新风处理至室内等温线或稍低于室内设计温度。经过比较分析,认为第2种方法是可取的。

关 键 词:风机盘管 新风系统 冬季空调工况 i-d图设计 新风比 新风终参数 建筑设备 空调系统

Abstract:For the most common fresh air handling way supplying fresh air directly into the rooms after it has been handled in fan coil with outdoor air systems, the paper gives the design method of i d pattern in winter air conditioning operating mode, which determines the state of supply air of fan coil units and the final parameter of winter fresh air througn the ratio of fresh air. For selecting the final parameter of fresh air after it has been handled,the authors gives three conditions:Winter fresh air is handled to room enthalpy;Winter fresh air is handled between room enthalpy line and room temperature line; Winter fresh air is handled to room temperature or a little lower than room temperature. The comparing result show that the second method is desirable after comparison.
Keywords:fan coil units plus fresh air systems  winter air conditioning operating mode  i-d pattern design  the ratio of fresh air  the final parameter of fresh air
