CONTROL END — The control end of a Modulinet unit isthe end containing a control block at the end plate of thevalve section of the unit. (Fig. 12.) The end of the unit op-posite the control end contains a blank block. The controlend of the Moduline unit is at the longer of the diffuser pro-jections from the plenum. In Fig. 13, the longer projection,B, is the control end.The filter, volume controller, and diffuser-mounted ther-mostat are applied to the control end of a master unit.Step 1 — Determine Air Volume (Cfm) Per Ter-minal — Before you can start making a layout, you mustknow the required air volumes (cfm).Use the cfm per zone you obtained from the cooling loadcalculation and, using Table 3, Recommended Maximum CfmPer Terminal, decide on the number of terminals you willneed in each zone.Cost dictates that the fewest number of Moduline units beused consistent with good design. The maximum cfm perunit that can be used (to keep the total number of units down)is mainly a function of maximum acceptable sound level.Perimeter zones with glass in the east, west, and southbuilding zones have peaks of rather short duration (i.e. loadsvary widely during the course of the day and year). There-fore, a higher sound level can be tolerated for these shortpeaks.Fig. 9 — Single ModulineT Unit Connected toSupply DuctFig. 10 — Moduline Units in Air SeriesFig. 11 — Master Unit and Slave UnitsFig. 12 — Control BlockFig. 13 — Control End of Unit24
