The following criteria should be considered for effective use of Positive Ventilation:
- The cone of air must cover the intake opening. The fan must be placed the correct distance from the structure such as that the cone of air forms a seal around the opening.
- The size and location of the discharge is important. The discharge, if at all possible should be as high and far away from the intake as is practical. The discharge size should be between 3/4 to 1/2 times the intake. This may not always be possible as the fire may have already dictated discharge locations and sizes; but whenever there is a choice, the above criteria should be used.
- It is important to control the ait flow between the intake and discharge. Positive pressure ventilation can move air long distances if proper control is maintained by opening and closing doors, windows, etc. It is important that firefighters understand not to open the structure too much: ie breaking windows, etc.
Many breeze conditioning systems are designed without the use of supply fans or make-up air units of any kind. The exhaust system creates a slight negative pressure in the building and outside air is induced through openings designed for this purpose. Intake louvers are usually mounted at the opposite end of the building from the exhaust fans in suitable wall locations. When the breeze conditioning system is in use, the louvers are opened manually or by damper motors; when not in use, the ventilator louvers are closed to provide weather protection. An alternative method for providing air intake openings is through the use of roof mounted hooded supply fans. American Coolair's Type PE PRV can be furnished without a fan for this purpose.
