Warm Weather Ventilation Package

Building Example:

Big box open ceiling without interior wall partitions – 500’ x 200’ x 36’

AirBoss “SmartAitr” Summer Ventilation is .5 Air Changes per Hour = 30,000 cfm

• Equipment would be (1) 30,000 Upblast Exhaust Fan + (1) Intake Louver
• (2) AirBoss ER-242-800s + (1) 24” x 36” Intake Hood to meet ASHRAE 62.1 (100,000’ x .06cfm/sf = 6000 cfm)

Operation:

When the outside temperature is cooler than the interior temperature of the facility, typically over-night, with the AirBoss units on, set the outside air dampers open with fans on and fully open the wall louvers.  This process will bring in the cooler night-air into the facility. The ER-242-800 AirBoss units will distribute and mix this air throughout the facility, cooling down the interior, (walls, ceiling, floor, racks, inventory and equipment).

Close the outside air dampers when the inside temperature equals the outside, typically early morning. This action traps cooler conditions in the facility and stops the intrusion of warmer outside air.  The AirBoss units run 24/7, circulating the cooler air. The AirBoss units also provide circulation to eliminate warm spots within and to provide direct air circulation around the occupants. This displaces the need for interior fans. When the air temperature inside the facility equals the temperature outside, the cycle stars over by reopening the dampers.

Conventional Summer Ventilation is (2) Air Changes per Hour = 120,000 cfm

• Equipment would be (4) 30,000 Upblast Exhaust Fans + (4) Intake Louvers
• Alternate would be (4) 30,000 Upblast Exhaust Fans + (8) Intake Louvers

Operation: Operators utilizing conventional systems attempt to achieve satisfactory ventilation results by dramatically increasing the quantity of equipment that is operating.  Even so, without AirBoss units, air circulation system will typically require ceiling or other fans to move air which will not lower the temperature and will only be effective when the air is directly blowing on the occupants.  Contrast conventional systems results with AirBoss systems: 1) conventional systems pull cooler overnight air into buildings through the intake louvers and out through the exhaust dampers but without a circulation system to distribute the air throughout the affect is minimized and supplements fans are typically deployed, 2) AirBoss results are documented to be far superior and much less costly to operate.
