摘要
针对风机盘管加独立新风空调系统,通过分析提出了应对最大冷负荷进行间歇附加,根据最大送风温差和最小换气次数确定系统最小送风量。提出了风机盘管机组选型的方法:根据设计全热冷量和风量初步选择机组型号,然后比较风机盘管能达到的空气处理热湿比和设计空气处理过程需要的热湿比,分三种情况对机组性能进行校核,确保风机盘管的除湿能力和降温能力都能满足设计要求。
To the air-conditioning system of fan-coil unit plus independent fresh air, through the analysis, it＇ s proposed that there should be a intermittent additional to the maximum cooling load, and the minimum air supply volume should be determined according to meet the goals both the limitation of maximum air supply temperature difference and the minimum ventilation rate. The fan-coil unit type can be preliminary selected by the aim to meet the design total cooling load and the air volume, then to check the performance of the fan-coil unit according to the rules by compare the fan-coin unit＇s actual angle scale and the design value to ensure both dehumidification and cooling capacity can meet the design requirement.
