Interaction of heat load and air supply in CAV systems.

By means of parametric analyses, the paper describes how the "constantness" of a Constant Air Volume system is affected by temperature differences resulting from heat load variations or otherwise. Several design related parameters are considered. The paper starts with the background, then an outline of the (simulation based) approach, and how calculations were performed. Results are shown with respect to consequences for volume flow rates and for energy consumption. The paper finishes with some conclusions, indicating there is a "flaw" in current ventilation standards, that it is hard to make real constant volume system, some preliminary conclusions with respect to energy consumption consequences, and that this type of problem really needs an integral (simulation) approach of building and systems.
