1. Data Center HVAC By: Joseph Schilling

2. HVAC HVAC stands for heating, ventilating, and air conditioning HVAC systems are used to provide thermal comfort and acceptable indoor air quality –In data centers it keeps the equipment cool and humidity down

4. Data Center A data center is a facility that is used to house computer systems and associated components Data centers typically use from 20-100 watts per square foot and up to 400 watts per square foot

6. Data Center HVAC HVAC uses approximately 25% of the power used in the data centers So efficiency of the HVAC unit is very important because the power needed by the processors cannot be changed.

7. Energy Reducing Have a more efficient HVAC unit Keep the data center at a higher but less fluxing temperature Use non-traditional methods of cooling –Use an ice or chilled water method that is cooled at night instead of during the day. –Use airside economizers which bring cool outside air in to supplement chillers.
