A paradigm shift is occurring in the design of HVAC systems for buildings, particularly in regard to RH control. Even in commercial buildings designers are scrutinizing the effectiveness of air conditioning systems in managing humidity levels. The concept of Divide & Conquer is gaining traction and utilizing ventilation air to manage the internal moisture load of buildings is becoming increasingly popular.
DRI Dedicated Outdoor Air Systems (DOAS) has emerged as the preferred option for designers to handle moisture load using Ventilation Air. After studying nearly 20 different configurations, DRI has developed a range of standard DOAS configuration that are widely used by designers today.
