HVAC System Diagram

A clear, cutaway diagram illustrates the internal components of a typical HVAC air handling unit. The depiction showcases the sequential stages of air treatment, starting with air filtration, followed by a cooling coil, a heating coil with connected piping for fluid circulation, and finally, a large fan responsible for circulating the conditioned air. The diagram also highlights the integration of supply and return ductwork, providing a comprehensive view of how air is processed and distributed in a modern heating, ventilation, and air conditioning system.
