VAV PRC012 EN S TRANE Application Considerations The parallel fan should be large enough to temper the design cooling airflow at 45 50 F to 50 55 F 7 2 10 C to 10 12 8 C For instance if the design cooling airflow is 1000 cfm at 55 F 472 L s at 12 8 C you will need 781 cfm of 48 F 368 L s of 8 9 C supply air and 219 cfm of 80 F 103 L s of 26 7 C plenum air The parallel fan can be sized for the 219 cfm 103 L s rather than the total room airflow The fan airflow plus the minimum primary airflow must be checked with the minimum airflow of the diffuse rs to insure that dumping doesn t occur If that is a concern the minimum could be adjusted up or the fan airflow could be adjusted up As the valve closes the downstream static pressure will decrease because the pressure is related to the airflow The fan will supply more air at the valve minimum condition than at design due to the decreased static pressure This should be a consideration when calculating how much airflow would occur at the minimum valve plus fan airflow condition The new fan airflow would be found by looking at a fan curve at the new SP point The new SP can be calculated Ean Airflow Valve Minimum X SP SP Fan Airflow Valve Design ce 2 Table 140 p 215 can be used to determine what percentage of the total airflow should come from the fan to temper the supply air assuming 80 F 26 7 C plenum air Table 140 Percentage of airfl

As total airflow varies so will static pressure making calculation of external static pressure dependent on unit type In many applications of parallel terminals a minimum primary airflow must be maintained to meet ventilation requirements This primary airflow contributes to the total resistance experienced by the fan and should be accounted for in all components downstream of the fan itself including electric coils Hot water coils positioned on the fan inlet are not affected by the additional primary airflow The static pressure resistance experienced by the fan due to the hot water coil is based on fan airflow only not the total heating airflow With series fan powered terminal units all airflow passes through the fan External static pressure requirements are the sum of the individual component pressure retirements at the design airflow of the unit Fan Motor Type The fan motor type that will be used for the unit will need to be known before fan selection can begin The ECM motor offers more efficient operation than the standard single speed PSC motor and will use different fan curves Because series fans operate in both heating and cooling mode payback is typically 2 3 years for the premium ECM option Refer to the Features and Benefits section to determine which motor is more appropriate for the unit Selection Once fan airflow and external static pressure are determined reference the fan curves in the performance data section Cr

Airflow Guidelines in each section for unit performance Space Temperature Control Space temperature control applications are where Trane emerged as an industry leader in quality and reliability This did not occur overnight and has continued to improve as our controller and control logic has improved over time STC employs controller logic designed to modulate the supply airstream and associated reheat either local or remote to exactly match the load requirements of the space Additionally minimum and maximum airflow and specific controller sequence requirements are pre programmed to ensure that appropriate ventilation standards are consistently maintained VAV PRC012 EN VAV PRC012 EN S TRANE DDC Controls When connected to a Trane Tracer Building Automation System trend logging remote alarming etc are available to fully utilize the power and capabilities of your systems General Operation Cooling In cooling control action the DDC controller matches primary airflow to cooling load The DDC controller will automatically change over to heating control action if the supply air temperature is above a configured editable setpoint When the supply air temperature is less than 10 degrees below this setpoint the controller will automatically switch to cooling control action The DDC controller first chooses the Tracer SC provided supply air temperature value to use for auto changeover If this is not available it uses the te

77. TRANE Application Considerations Static Pressure Measurement Errors Improper measurement techniques for static pressure can lead many to mistakenly believe that the terminal unit is causing a large pressure drop in the system The chief error made here is taking a static pressure measurement in turbulent locations such as flexible ductwork or near transitions This produces invalid static pressure readings Another error commonly made is trying to read the static pressure at the same point as the flow sensing device The inlets to VAV terminal units produce turbulence and will give poor readings Flow sensors with their multiple point averaging capability are best equipped to deal with this type of flow while a single point static probe is not Another common error is the incorrect orientation of the static pressure probe The static pressure is correctly measured when the probe is oriented perpendicular to the direction of airflow The probe or a part of it should never be facing the direction of airflow because the total pressure will influence the reading of the probe Unit Conversions 232 Table 142 Conversions of length and area To convert From To Multiply by Length In m 0 0254 Length Ft m 0 3048 Length m In 39 3701 Length m Ft 3 28084 Area In 2 m2 0 00064516 Area Ft2 m2 0 092903 Area m2 In 2 1550 Area m2 Ft2 10 7639 Table 143 Conversions of velocity pressure and flow rate

NE Application Considerations Remote Heat In some zones of a single duct VAV system perimeter heating equipment remote from the terminal unit is used to add heat to the zone when the cooling load is lower than the minimum cooling capacity of the VAV terminal unit Heat is added directly to the zone while cool supply air continues to enter the zone at a minimum rate for zone ventilation Terminal Reheat In some zones of a single duct VAV system a minimum flow of cool supply air is reheated at the terminal unit before entering the zone Terminal reheat can be provided by electrical resistance heaters or by hot water coils Parallel Fan Powered Heat In some zones of a single duct VAV system cool supply air at minimum flow is mixed with warm plenum air before entering the zone at a constant flow rate A fan in the terminal unit in parallel with the central fan draws air from the plenum whenever the zone requires heat Series Fan Powered Heat In some zones of a single duct VAV system the airflow to the zone is held constant during both heating and cooling by a terminal unit fan that is in series with the central fan The terminal unit fan runs continuously When the zone requires heat cool supply air at minimum flow is mixed with warm return plenum air before entering the zone VariTrane VAV Terminal Units The function of the VariTrane terminal unit in a VAV control zone is to vary the volumetric airflow rate to the zone VariT
