Tower Location
The cooling tower must be located at such distance and direction
to avoid the possibility of contaminated tower discharge air being
drawn into building fresh air intake ducts. The purchaser should ob-
tain the services of a Licensed Professional Engineer or Registered
Architect to certify that the location of the tower is in compliance
with applicable air pollution, fire, and clean air codes.
Locate so prevailing wind will blow into the louvered face, and direct fan
discharge away from building surfaces. Locate so there is free air flow to and
from the tower. Allow clearance on all sides for maintenance.
Indoor Installation
Use a duct from the tower air discharge to the outside. You may also want to
install an inlet air duct. Do not allow the total pressure loss through ducts to
exceed 25 Pa. To minimize pressure losses:
•
Use 20% oversize ducts.
•
Avoid sharp turns or abrupt changes in size.
•
Keep duct length to a minimum.
•
Screened or louvered openings should have a net free area at least 20%
greater than the tower discharge opening area.
Attach ducts to the tower using flexible connections, and support ducts
independently from the tower. Provide access openings for servicing the me-
chanical equipment if air discharge ducts are installed. If the duct discharges
into the prevailing wind, you may need to install a windbreak or an elbow to
serve as a deflector. Ducts installed on towers with year-round usage should
be water tight and insulated to prevent condensation.
