The typical Procedure of the HVAC system includes temperature Manage, air volume regulation, and air purification. These methods consist of air ingestion through the setting, filtration, heating or cooling, and distribution by means of ductwork or other signifies inside the making.
IU means Induction Unit. IU is actually a secondary air con device that is usually Situated close to the goal cooling/heating space. It's going to take in air conditioned by the primary air con device which include an AHU, and even further amazing/heat the air on the focus on House temperature.
Within an HVAC system, certain components are devoted to heating, cooling, and air distribution. Knowing these parts is very important for grasping how they collectively retain the desired local weather inside a Place.
