Topic #1 – “Basics of Air Distribution”
The basic physics of air distribution must be fully understood before one can properly select components for a project. This lecture will cover:
• Understanding Terminology
• ADPI (Air Diffusion Performance Index)
• Proper Diffuser Selection
• Common Product Groups
– Well Mixed (Inductive) Air Distribution
– Non Inductive Air Distribution
• Value of Diffuser Selection
Topic #2 – Hospital Operating Room, Laboratory and Clean Room Air Distribution
Air flows in Hospital OR’s, laboratories and clean rooms are special cases, which require an understanding of the special needs in rooms with patients on an operating table, rooms with fume hoods, and in clean rooms, with much higher airflow rates. All have different needs and require special considerations and equipment.
Lunch & Presentation 12:00 pm – 1:30 pm – West Auditorium
Methods of Effective Room Air Distribution
In order to meet the increased expectations of building occupants, designers must be aware of the conflicts between first cost economics, occupant productivity and life cycle costs. Buildings that do not meet the needs of the occupants often result in expensive redesign or worse, result in lawsuits against all parties involved. First, we need to understand the rules:
1. LEED: 2009 is out, and many are not aware of some significant changes that have resulted in air distribution, IAQ and Comfort.
2. Thermal Comfort: Determining optimum occupant comfort strategies. ASHRAE Standard 55 has been revised.
3. Acoustics: Accurately predicting end use environments. A new classroom acoustical requirement needs to be understood.
4. IAQ: The changing face of ASHRAE Standard 62.1, and upcoming developments.
I will briefly cover pros and cons of all 4 methods of air delivery:
- Overhead air distribution
- DV (Displacement Ventilation)
- Underfloor Air Distribution (UFAD)
- Chilled Beams and the DOAS Fan Box
