Controlling Variable Volume Critical Exhaust Systems To Optimize Performance and Minimize Energy Cost

Keith Lins, M K. Plastics Corporation

While there is significant focus placed on conditioned environment HVAC design, this presentation will discuss the nature of variable volume critical exhaust systems, the challenges associated with controlling these systems, and design approaches to optimize system operation, while minimizing associated energy cost. The discussion will address the need to understand the turndown range, time distributions associated with that range, fundamental design considerations, and optimal fan equipment selection techniques. Then we will explain control sequence design to properly manage and report the critical parameters, respond to external inputs (i,e, air quality, meteorologic conditions, etc.), while operating continuously, safely, and with minimal energy consumption. The presentation will require at least 30 minutes.
