讨论了VAV实验室通风柜表面速度控制、空间增压和温度控制的各种设计概念。对比了跟踪和差压控制设计，以及表面速度控制的窗扇/流量和侧壁速度传感方法。并对计算机硬件性能评估方法提出了建议。单位:I-PCITION:研讨会，ASHRAE交易，1988年，第94卷，pt。2、渥太华

Various design concepts for fume hood face velocity control, space pressurization, and temperature control in VAV laboratories are discussed. Tracking and differential pressure control designs are contrasted as are sash/flow and side wall velocity-sensing methods of face velocity control. Suggestions as to methods of computer hardware performance evaluation are also given.Units: I-P
