摘要
分析指出了由于动压检测及变送精度等限制，风机跟踪系统不能维持足够的最小新风量，ＣＯ２控制则不一定能满足室内空气品质对新风量的要求。推荐专设风机系统，讨论了设计中应考虑的混合箱压力变化和专用新风机选用问题，以及运行中的控制问题。
Points out that adequate minimum ventilation air can not be maintained by the fan tracking method because of its inherent limit in measurement accuracy of the velocity pressure and the CO 2 based method may not meet the requirements of indoor air quality. Recommends an injection fan system as a technique to avoid these inadequacies and presents its design and operation.
