While there are no facts and figures to show how many buildings provide the correct amount of makeup air, it can be stated that there are probably a great many that do not have sufficient makeup air. And there\'s no one solution that is available for every building. Each building must be analyzed with a careful air balance calculation and evaluated based on the diversity of sources of exhaust air and infiltration.

 Industrial Air Handling Units for Climate Control

Makeup air is vitally important to the health and welfare of a building and its occupants. If the proper amount of makeup air is not introduced into a space, consequences can range from exterior doors that are hard to open or close, to buildups of carbon monoxide in the space, to fume hoods that don't actually control the contaminants they were intended to control. In addition, the outside air that is brought into a building to "make up" the amount of air that has been exhausted has a very significant impact on cooling and heating capacities.

 Direct-Fired Industrial Makeup Air Units
by Oleg Tchechel | April 22, 2009
Category: Business / Industrial Mechanical
Gas-Fired Pressurization Units move large quantities of air at low temperature differentials (usually 50° or less), which is a strategy to minimize temperature stratification in the large spaces they are employed to heat. The equipment is typically mounted on the roof of the facility or at grade on elevated supports to ensure that the supply air is delivered high. The high air delivery allows for a longer “throw” of the air, thereby requiring less equipment to cover the required floor area. The most common fuel is natural gas, however, units can be converted to burn propane. There are two primary categories of gas-fired AHUs: indirect-fired and direct-fired.

Constant air supply with variable-speed exhaust is recommended where a hot or contaminated environment must be ventilated while maintaining room pressure. Unit may be interlocked to that it only operates with the exhaust system.
Variable Air Supply with constant-speed exhaust may be preferred where fume exhausters or fume hoods are used to provide critical ventilation of contaminants from a “clean” environment while make-up air is used to maintain a positive pressure to prevent infiltration.
