Understanding Air Handling Systems and Fresh Air Handling Units
Introduction to Air Handling Systems Air handling systems play a pivotal role in maintaining indoor air quality and ensuring the comfort and health of building occupants. These systems are integral components of heating, ventilation, and air conditioning (HVAC) frameworks, tasked with regulating and circulating air throughout a building. An air handling system, often referred to as an air handler, typically consists of a large metal box containing a blower, heating or cooling elements, filter racks or chambers, sound attenuators, and dampers. Air handling systems can be connected to a ductwork ventilation system that distributes the conditioned air through the building and returns it to the air handler. Key Components of Air Handling Systems Blower/Fan : This component is essential for moving air through the system. It ensures that air reaches every part of the building, maintaining consistent air quality and temperature. Heating and Cooling Elements : These include coils or heat exch
