8 Theselection procedure is iterative innature which makes computerselection of Fan-Powered VAVterminals involves four elements: Air valve selection Heating coil selection Fan size and selection AcousticsAir Valve SelectionProvided in the performance datasection of the catalog is the wide-openair pressure drop vs. airflow curve. Toselect an air valve, locate the requireddesign cooling airflow and find itsvertical intersection with the smallestair valve size that has air pressure dropequal to or lower than the maximumwide-open air pressure Coil SelectionSupply Air TemperatureThe first step required when selecting aheating coil is to determine the heatingsupply air temperature to the space,calculated using the heat transferequation.

9 Air temperature difference isdefined as the heating supply airtemperature to the space minus thewinter room design temperature. Thezone design heat loss rate is denotedby the letter Q. Supply air temperatureto the space equals the leaving airtemperature (LAT) for the terminal Leaving Air TemperatureOnce the terminal unit LAT isdetermined, the heating requirementsfor the coil can be calculated. Theleaving air temperature for the coil of aparallel Fan-Powered terminal unitvaries based on the type of unitinstalled heat being coil LAT equals terminal unitLAT because the coil is located on theunit discharge.

10 Hot water coils,however, are located on the enteringair side of the fan. In this case, coil LATis calculated using a mixing the unit heating airflow and LAT,minimum primary airflow at its supplyair temperature, and the volume ofheated plenum air, the leaving airtemperature for the hot water coil canbe determined (see the unit selectionexample that follows for more details).Coil Entering Air TemperatureThe entering air temperature (EAT) tothe coil also varies based on the coilposition on the coil EAT equals thetemperature of blended primary airand plenum air because the coil is in ablow-thru configuration.
