Tunnel Ventilation

For tunnel ventilation the building must be sealed for ventilation to be effective. All roof vents, chimneys, side vents, windows, doors, and openings other than the air inlet area opposite of the fan wall must be closed.

Buildings with open ceilings require baffles. Baffles should be equally spaced throughout the length of the building and hung as low as possible without effecting the daily routine of machinery. Baffles ensure that the air movement maintains the velocity.

Evaporative cooling systems for the air inlet end of tunnel ventilation system are frequently recommended. Air intake is determined by the number of fans.

During winter fewer fans are required to remove gas, keep air fresh, and humidity low. The winter rate should be approximately 50 to 100 cfm per cow.
