How Air Supply Systems Work: A Comprehensive Guide
Air supply systems play a critical role in maintaining comfortable and healthy indoor environments by delivering fresh, conditioned air to different parts of a building. Found in residential, commercial, and industrial HVAC applications, these systems are designed to regulate air temperature, humidity, and cleanliness while ensuring consistent airflow. Understanding how they work helps building owners, engineers, and facility managers optimise performance and energy efficiency. Core Components of Air Supply Systems An air supply system consists of several integrated components working together to control airflow. At the heart of the system is the air handling unit (AHU), which houses fans, filters, coils, and sometimes humidifiers or dehumidifiers. Ductwork channels distribute the air to designated spaces, while return ducts help circulate used air back to the system. In more advanced setups, sensors and thermostats regulate temperature and flow to maintain desired comfort levels auto...
