Air vs Water
1” dia water pipe can deliver the same cooling as duct 300-350 times its size at the
same fluid temperature

Air Flow Pattern
![Page 5: Acb presentation](https://reader036.vdocuments.net/reader036/viewer/2022081507/58ae24591a28ab7e4a8b60eb/html5/thumbnails/5.jpg)
Lower Energy Consumption(ASHRAE 90.1)
• Lower Airflow i.e. Lower Fan Power • Higher Chiller COP
100% Outside Air • i.e. Healthier Indoor Environment (ASHRAE 62.1)
Building Material Saving ( Glazing& RC)• Smaller Ductwork ; Reduction in Floor-to-Floor Slab height
• Can ‘avoid’ false ceiling and maintain aesthetics
Floor Space Saving • Smaller AHU Room• Smaller Cavity & Risers
Higher Thermal Comfort (ASHRAE 55.2)• Room Air-Velocities within band• Better distribution of temperature
Extremely Low Noise
Reduced Maintenance & Intrusion on Tenant

Floor Space Saving
• Conventional 4 AHU design : 1596 ft2 per floor• Chilled Beam 4 AHU design : 560 ft2 per floor• For 6 floors (Typical Office), total saving
6 x ( 1596 – 560 ft2 ) : 6216 ft2
