Standard 62-2001 Addendum 62n - Single-path multiple-zone system design

The design of "simple" ventilation systems in compliance with Standard 62-2001 Addentum 62n requirements has already been discussed in articles. This paper focuses mainly on the design of a more complex set of ventilation systems, namely single-path multiple-zone recirculating systems.The calculation procedures to reduce both underventilation and unnecessary over-ventilation are clarified and help for determining system ventilation efficiency.
