VAV Laboratory Exhaust Solutions to Comply With ANSI Z 9.5 and California Title 24: Turndown, Fan and Component Selection, and Control Fundamentals.

Keith Lins, M. K. Plastics Corporation

A proper and effective VAV laboratory exhaust control system to satisfy the requirements of ANSI Z 9.5 and California Title 24 begins with proper equipment and component selection. This presentation will address the impact of understanding turndown range and predominant operating range on fan selection. The design of a safe, workable, reliable, and efficient VAV lab exhaust control system must include a clear understanding of the mechanical and electrical components, their performance characteristic, and the manner in which these actually respond to control commands. This presentation will discuss these issues, with case history references.

Learning Objectives

  • Understanding VAV laboratory exhaust systems.
  • How to optimize exhaust fan selection for VAV application.
  • How the laboratory exhaust system components work and must interact in a VAV application.
  • We will demonstrate considerations, based on experiences, for designing a safe, workable (stable), energy saving VAV lab exhaust control system that accommodate turndown, pressure maintenance, and outside exhaust dispersion requirements of ANSI Z 9.5 and California Title 24.
