Laboratories Best Practices - Manifolding Exhaust

Overview

Manifolding laboratory exhaust in laboratory buildings provides substantial energy and first-cost savings opportunities when compared to separately ducted, multiple exhaust fans. A manifolded system also offers a number of benefits, including increased fume dilution, enhanced personnel safety, augmented redundancy and improved design flexibility. A holistic, team-based approach is important when determining the design and appropriateness of a manifolded exhaust system. Design decisions regarding fan type, stack location, plenum configuration, ductwork details, controls, and screening systems need careful attention to optimize the energy reductions inherently obtainable with a manifolded exhaust system.

In this course the student will learn the benefits of using manifolded exhaust in laboratories. One of the benefits associated with manifolded exhaust systems is an increased momentum, result-ing in improved plume rise of the discharged flow. A second benefit of manifolding is increased internal dilution of the combined exhaust stream. More benefits are outlined in this course source document.

The student is expected to read and review the material contained in the Laboratories For The 21st Century: Best Practice Guide – Manifolding Laboratory Exhaust Systems, DOE/GO-102006-April 2007.

The student must take a multiple-choice quiz consisting of ten (10) questions at the end of this course to obtain 1 PDH credit.
