Carrier TDP 613 HVAC Fans in VAV Systems
Technical Development Programs (Carrier TDP 613 HVAC Fans in VAV Systems) are modules of technical training on HVAC theory, system design, equipment selection and application topics. They are targeted at engineers and designers who wish to develop their knowledge in this field to effectively design, specify, sell or apply HV AC equipment in commercial applications.
One of the reasons that VA V (Variable Air Volume) systems are popular is because they provide fan energy savings that constant volume systems cannot. As a general statement, fans consume more energy in a typical HVAC system than the compressors. Therefore, it is important that the correct type of VA V fan be used for the application. Equally important is that the fan in a VAV system is stable at part load operation, as well as full load operation. This TDP module will explain the types of fans that can be used in VA V systems, as well as the controls that may be applied to regulate each.

Building heat loads change throughout the seasons due to variations in outside temperature and shift of solar load patterns. Additionally, building occupant and lighting load patterns change as building space use varies. An air-conditioning system must be able to match these varying load patterns while minimizing the use of energy.
