新风量选择按每人每小时30m³计算并预留冗余，三口之家实际需求约90-120m³/h，但设备标称新风量需选150m³/h以上，因为标称值通常是空载最大值，接管道后衰减30%-40%

Unverified新风量按每人每小时30m³计算，再乘以房间人数取最大值；例如三口之家客厅需≥90m³/h，但考虑管道损耗和滤芯衰减，选购时应按理论值1.5倍留余量，即选150m³/h以上机型92% similar Unverified换气量选型按每人每小时30m³新风计算，3口之家需≥90m³/h，但考虑滤网衰减和管道损耗应上浮30%，即实际选购≥120m³/h机型92% similar Unverified新风量应按每人每小时≥30m³计算，同时满足房屋总换气次数≥0.5次/h。例如80㎡（约200m³）住3人的家庭，需选额定风量≥150m³/h的机型（人均需求90+换气量100取大值并留余量）90% similar Unverified新风换气量选型按每人每小时30m³新风计算，或按房屋面积×层高×换气次数（居家0.5-1次/小时）取大值，例如100㎡三口之家至少需要200-250m³/h的额定风量88% similar Unverified新风量选择按人均30m³/h计算，再乘以1.3~1.5的余量系数。三口之家日常需选90~135m³/h机型，若房屋密闭性差或有明火厨房需选150m³/h以上88% similar
