实验室通风柜的运行占据了研究设施中使用的大部分能源。该能量由风扇系统和补给空气调节消耗。虽然这些能源消耗者与其他空气处理系统没有什么不同，但与排烟系统相关的约束条件带来了难题。重要的制约因素是工人安全、沉淀、分散、腐蚀和可靠性。随着通风柜系统的发展，定容系统已被可变容积系统取代- 具有热回收系统和精细控制策略的容积系统。这里描述的是一个已投入运行的节能系统，并讨论了它如何满足设计约束，以及它与其他流行设计的对比。单位:I-PCITION:研讨会，ASHRAE交易，1987年，第93卷，pt。田纳西州纳什维尔2号

The operation of laboratory fume hoods accounts for most of the energy used in research facilities. The energy is consumed by the fan systems and conditioning of the makeup air. While these energy consumers are not different from other air-handling systems, the constraints associated with a fume system present difficult problems. The significant constraints are worker safety, precipitation, dispersion, corrosion, and reliability. The evolution of fume hood systems has seen constant-volume systems give way to variable-volume systems having heat recovery systems and refined control strategies. Described here is an energy-conserving system that has been placed in operation and a discussion of how it has met the design constraints and how it contrasts with other popular designs.Units: I-P
