What is Air Distribution  ?
Air distribution An essential feature for laying out air conditioning systems is air flow, which can be designed to be constant or variable. Accordingly, a differentiation is made between constant volume flow systems (CAV) and variable volume flow systems (VAV). These features can also apply to sections of a system since a combination of both types is technically feasible. The system selected depends on the overall concept of the building services. A constant system is only possible where other systems ensure zone-based temperature control, e.g. heating surfaces, or where temperature control is not requiredConstant volume systems provide every location with a constant airflow. However, a variety of systems with technical and economic differences are available.
