ASHRAE DOAS Design Guide Completed by SEG
Sustainable Engineering Group completed a research project relating to “Development of the ASHRAE Design Guide for Dedicated Outdoor-Air Systems.” This project will also be added as a new chapter in the HVAC Systems and Equipment volume of the ASHRAE Handbook.
The intent of the design guide is to compile the existing knowledge into a single guide, focused on providing the working-level HVAC designer with the tools needed to understand the issues related to DOAS and then to design a DOAS which ventilates a building at lower installed cost, less overall annual building energy use, and increased indoor environmental quality. This guide is focused on design considerations that are specifically relevant to DOAS. So it is not intended to be a general guide for designing any HVAC system; rather it addresses those issues that should be considered when incorporating DOAS into an overall HVAC design.
