Course Outline
This one hour online course discusses several strategies for reducing the pressure drop in each component of the air distribution system.
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:
- HVAC system pressure loss reduction strategies;
- Energy recovery system considerations; and
- Laboratory exhaust stack design considerations.
Intended Audience
This course is intended for mechanical engineers.
Benefit for Attendee
Attendee of this course will be able to understand more thoroughly how to design laboratory ventilation systems with lower pressure drops in the duct systems to reduce energy used by the fans.
Course Introduction
Specifying low-pressure-drop design for a laboratory’s ventilation system has great potential for energy savings. High pressure drop results in a ventilation system with high power consumption. Pressure drop should be addressed throughout both sides including the supply and the exhaust.

Course Summary
Laboratory ventilation systems are designed to isolate and protect occupants from hazardous fumes and to provide outside air at a comfortable temperature. Programmatic needs such as exhaust devices, internal loads, and safety-mandated air changes usually call for a large volume of conditioned make-up air. Where a high volume of air must be exhausted, a once-through ventilation system is usually required. Once-through systems are often mandated by codes that prohibit the recirculation of air from a laboratory space to adjacent spaces. The operational costs associated with high-airflow systems are magnified when laboratory ventilation systems are operated continuously—24 hours per day, 7 days per week.
