| 摘 要： | 空气调节教科书与中央空调设计手册,对系统新风量取值有二种表述。这两种表述在特殊情况下存在着矛盾。系统最小新风量应是局部排风量加上保持室内正压所需风量之和与卫生要求所需风量比较取二者最大值。若新风量不足系统总风量百分之十时,则应加大到百分之十。

| Abstract: | There are two expressions for the system fresh air volume in the textbook of air conditioning and the design handbook of central air conditioner.These two expressions are inconsistent in special situation.The minimum fresh air volume of the system should be the maximum value between the values which local air exhaust plus the air volume that keep the indoor pressure positive and the value which the air volume need to meet the healthy requirement.If the fresh air volume is short of 10% of the total air volume,it should be added to 10%. |
