Heating/Piping/Air Conditioning Engineering;Feb2008, Vol. 80 Issue 2, p44
The article discusses the simple variable-air-volume- (VAV-) box selection has turned an iterative process complicated by energy-code and ventilation-code requirements. VAV-box selection should be performed as part of total-air-distribution-system design and a variety of VAV boxes includes cooling only, cooling with reheat, dual-duct, and fan-powered. It also focuses primarily on VAV-box selection and meeting the latest energy-code requirements and on cooling-with-electric-reheat VAV boxes.
