Four strategies for implementing ASHRAE 62.1 in HVAC systems

摘要

hen designing HVAC systems to meet local codes and ASHRAE 62.1-2016: Ventilation for Acceptable Indoor Air Quality, reducing the amount of necessary outside air that needs to be conditioned for acceptable indoor use is allowed, and there are several means by which the designer can approach such reductions, all of which are described within this ASHRAE Standard. Four strategies will be examined to save energy and realize cost savings. Approaching HVAC outdoor-air calculations in this manner may not be the easiest way to design ventilation systems, but the payoff could make it worthwhile. The potential reduction in required outdoor airflow could exceed 50% depending on what combination of strategies are implemented for a given HVAC system or a combination of systems.
