TECHNICAL PROGRAM:
Title: Impact of DOAS Dew Point on Space Humidity
Abstract: Dedicated outdoor-air systems (DOAS) are used in a variety of building types to provide ventilation; and when the outdoor air is dehumidified, a DOAS can help prevent high space humidity levels. But many of the systems designed and installed today are not dehumidifying adequately. This presentation will demonstrate how space humidity levels are affected by the DOAS discharge-air conditions, at both full load and part load.
Learning objectives:
- Understand the impact of DOAS supply-air dew point on space humidity levels
- Complete the steps for determining the “right” DOAS supply-air dew point for a given application
- Identify the factors that influence the required DOAS supply-air dew point
