Application:
According to the Occupational Safety and Health Administration (OSHA), ventilation is one of the most important controls available to manage air quality in the work environment. Ventilating is the replacement of air in an indoor environment for the purpose of improving the air quality. Air quality improvement includes temperature, oxygen replenishment, moisture removal, odor, smoke, heat, dust, carbon dioxide, or bacteria removal. Air ventilation includes exchanging the indoor air with outdoor air, like in the air conditioning process, or circulating the air within the building. The ventilation process occurs in either mechanical/forced or natural ventilation. Some form of ventilation is needed for any type of structure.

Operation:
Mechanical/forced ventilation utilizes an air handling unit (AHU) to circulate air. The AHU consists of a blower, heating/cooling elements, filter racks/chambers, sound attenuators, and dampers within a container. The container connects to the ductwork and filters the air conditioning and heat before it is distributed and vented throughout the building.

Special Considerations:
Duct design should be smart. Ducts that are too small for the space results in loud ambient fan noise. Ducts that are too large, result in wasted material spending and an inefficient system. Finding the right balance will result in minimal material costs and efficient ventilation.
