Outdoor base station air pressure balance

What is an outside air pressure pickup port?

Automated Logic’a Outside Air Pressure Pickup Port is an easy, economical and attractive way of measuring outdoor static pressure. The pickup port also helps stabilize readings because it significantly reduces the pressure fluctuations caused by wind gusts.

How do building pressure and outdoor airflow control work?

Building pressure and outdoor airflow control must be integrated for proper system performance. Pressure results from the development of a pressurization flow between adjacent pressure zones. A zone will be positive to an adjacent zone if the pressurization flow across the zone barrier is positive.

What is air balancing?

Air balancing is a fundamental design skill for HVAC engineers and consultants. Depending on the intended purpose of each building area, it may require negative, positive or neutral pressurization.

What is outdoor static pressure?

The outdoor static pressure is the atmospheric pressure at the building site. The building may have positive, neutral, or negative pressure with respect to the outside atmosphere. Differences in pressure are due to powered supply or exhaust fans and are usually less than 0.1 inches of water.

How do I determine the outdoor air setpoint for pressurization?

In addition, the outdoor air setpoint for pressurization should be established by adding the pressurization flow requirement to the sum of the local exhausts in the zone served by the air handling system. The greater of the two dictates the outdoor air setpoint.

What is a Bapi pressure pickup port?

BAPI’s Outside Pressure Pickup Port helps stabilize pressure readings by reducing the pressure fluctuations caused by wind gusts. The unit is also very rugged with a UV-resistant and flame-retardant housing to perform and last under harsh conditions. It is available in Rooftop or Wall Mount or Vertical Mount for building soffit or ceilings.
