Laboratories Best Practices: Manifolding Exhaust in Laboratories

Steven G. Liescheidt, P.E., CCS, CCPR

Course Outline

This one hour online course discusses how architectural and mechanical designers need to collaborate with specialized consultants to perform dispersion studies, re-entrainment analyses, and acoustical reviews in order to implement manifolded exhaust strategies.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of course materials.

Learning Objective

At the conclusion of this course, the student will:

• Be able to understand opportunities to implement manifolded exhaust systems;
• Be able to understand energy efficiency benefits of manifolded exhaust systems; and
• Be able to look at performance examples from case studies implementing laboratory manifolded exhaust strategies.
  
  

Intended Audience

This course is intended for mechanical engineers.

Benefit for Attendee

Attendee of this course will be able to better the benefits of implementing manifolded exhaust systems in laboratory buildings from energy and operational perspectives.

Course Introduction

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.

Course Content

This course is primarily based on Laboratories For The 21st Century: Best Practice Guide – Manifolding Laboratory Exhaust Systems, DOE/GO-102006-April 2007:

Course Summary

This course source document discusses 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.
