- Abstract
- In general, HVAC systems for clean room facilities require significant energy to maintain the indoor environment. Due to high air change rates, reducing operating energy consumptions has been a critical issue. The purpose of this paper is to investigate the energy saving potentials of indirect and direct evaporative cooler assisted 100% outdoor air system (IDECOAS) serving a clean room. This research also provides a practical insight on how cooling and heating coil loads can be reduced and how to design the proposed system. In this study, it was assumed that a clean room is served by four different types of HVAC systems: a variable air volume system (VAV), an air washer system (AIRWASH), a dedicated outdoor air system (DOAS), and IDECOAS. It was found that DOAS and IDECOAS can reduce the annual cooling and heating coil loads by over 65.7% and 59.5%, respectively, compared with the VAV.
