Laboratory Exhaust Control: Techniques and Approaches for Energy Efficient, Safe, and Stable Systems

Lance Chen, M. K. Plastics Corporation

Laboratory exhaust systems can typically consume huge amounts of energy. Using constant speed exhaust fans with bypass dampers for system control is inefficient. And, in some areas, code now requires the exhaust volume to be variable. This presentation will explain control approaches to vary the lab exhaust volume while ensuring that the system remains safe and stable. From experience, we know that there are Dos and Don'ts. Principles and techniques that work will be shared.

Learning Objectives

  • Understanding and defining the functional objectives for the laboratory exhaust control system.
  • Understanding variable volume exhaust, and the basic techniques to control it to maintain safety and minimize energy costs.
  • Understanding advanced multi-point variable volume exhaust systems.
  • Learned from experience: pointers to ensure a safe, stable system.
