PRINCIPLES OF OPERATIONMode HVI Energy Miser Jet Induction terminals combinethe benefits of both single duct VAV cooling and inductionto maintain room air motion and efficient space tempera-ture control. The primary conditioned supply air flow rateis controlled by pressure independent pneumatic, elec-tronic analog, or DDC controls, see pages G-17, 18. Inresponse to the space thermostat demand, the controlsoperate a high efficiency variable nozzle.

The high velocity jet controlled by the nozzle creates a neg-ative pressure within the unit casing. As the primary airflow modulates from maximum to minimum flow, the sec-ondary induction damper simultaneously opens, allowingincreased induction air. Pages G-17, 18 show typicalsequences of operation. Optional Electric or Hot Waterheating coils may be added for perimeter zones requiringheat.

INDUCTION CHARACTERISTICSThe primary air flow is regulated by the flow controls, andis reset by varying the primary nozzle opening. The inducedair capacity varies directly as the inlet static pressureincreases, and inversely as the downstream pressureincreases.

The induction characteristic curves shown illustrate thepercent of Total Air and Induced Air for the full range of pri-mary flow rates.

The values of Total and Induced Air are given as percent-ages. Values may be interpolated at other inlet and down-stream pressures. Inlet pressures shown are without hotwater coils. The pressure requirement of the coil at maxi-mum primary flow must be added to the inlet static pres-sure shown for the given induction curve.

HOW TO READ INDUCTION CHARTSExample: Determine the induced and total aircapacity of an 8” HVI terminal when the pri-mary flow is at 50% of the maximum designflow of 800 CFM at .5” inlet static pressureand .10” downstream static pressure (DSP).The downstream pressure includes the resist-ance of the downstream duct work, diffusers,plus the pressure drop of the return airthrough the ceiling opening. Referencing Graph 14.1 for the HVI at .5” inlet static pres-sure, at 50% primary flow rate, find the totaland Induced Air percentages on the .10”Downstream Ps Curve. The Total Air deliveredis 83% of maximum flow (800 CFM) or 800 x.83 = 655 CFM. The Induced air is 33% ofmaximum flow or 265 CFM. Total Flow =Induced Flow + Primary Flow = 265 CFM +400 CFM = 665 CFM.

Knowing the heating load of the space (bTUH or MbH), room temp setpoint, and the air flow rate during heating (based on minimum ventila-

tion rates, max recommended discharge temps for best ADPI, etc.), determine the supply air temperature required to satisfy the load:

Supply Air Temp = (MbH x 926 / CFM) + Room Temp Setpoint

2. The hot water heating coil is located in the primary air stream, and heats only the primary air flow. During the heating cycle, the total flow intothe space is a mixture of induced plenum air and heated primary air, with each component having a different CFM value and temperature.The supply air temperature (SAT) into the space must then be calculated as:

SAT = [(Induced CFM / Total CFM) x Induced Temp] + [(Primary CFM / Total CFM) x Coil LAT]

Example:

• Primary Air: 55°F, 500 CFM• Hot water Coil LAT: 105 F• Induction Air: 78°F, 350 CFM• Total Air to Space: 500 + 350 = 850 CFM

SAT = [(350 CFM / 850 CFM x 78°F] + [(500 CFM / 850 CFM) x 105°F] = 94°F

by rearrangement:

Coil LAT = [(SAT x Total CFM) – (Induced CFM x Induced Temp)] / Primary CFM

Applying energy transfer equations for electric or hot water coils determines performance characteristics required to select the coil:

water Coils: bTUH = CFM x 1.08 x (LAT – EAT)

Electric Coils: kw = CFM x (LAT – EAT) / 3,160

HVI JET INDUCTION TERMINALSFurnish and install Anemostat type HVI Jet Induction Terminals /HVIR Jet induction Terminals with (Hot Water) (Electric Heat)where shown on plans and as scheduled.

PERFORMANCEThe air terminals shall have been tested in accordance with theARI STD 880. The minimum operating static pressure anddownstream duct static pressure shall be as scheduled fordesign induction capacities. The induction terminal shall be capa-ble of operation down to .5” inlet static pressure, with .10” stat-ic pressure in the downstream duct, while inducing up to 50%secondary air as the induction damper is modulated. The dis-charge and radiated sound power levels shall not exceed the NCvalues as shown on the terminal schedule at the inlet staticpressure shown, using attenuation assumptions as dictated byARI 880, appendix E.

CONSTRUCTIONThe unit casing shall be fabricated from minimum 22 gage zinccoated sheet steel. Sealant approved for duct use and conform-ing to NFPA 90A shall be used during construction of theassembly between mating parts to form a leak resistant assem-bly. The single inlet shall be of the diameter as scheduled. A 1”long rectangular discharge collar shall be provided for the dis-charge duct connection. The attenuator / venturi section shallbe lined with thermal/acoustical glass fiber insulation that is 1”thick, high density ductboard. The casing of the terminal shall belined with dual density thermal acoustical glass fiber not lessthan 1/2” thick, and shall conform to NFPA 90A and UL 181.Each terminal shall be provided with a bottom access door.

The primary air nozzle shall be constructed from aluminum, andshall vary the primary air flow rate by varying the area of the noz-zle opening. The high velocity jet shall create sufficient negativepressure within the casing to induce the quantity of air as sched-uled.

PNEUMATIC CONTROL SYSTEMSThe pneumatic controls shall be suitable for a 20 psi controlsystem. The sequence of operation is based on AnemostatControl Package JP-3XXX. The pneumatic actuators shall be fur-nished and mounted by the unit manufacturer to sequence boththe primary and induction dampers as required. The primarydamper shall fail in an (open) (closed) position should the mainair fall to 0 psi. The pneumatic velocity controller shall be fur-nished and mounted by the unit manufacturer, and the maxi-mum and minimum flow setpoints shall be set at the factory,and shall be field adjustable. The reset span shall remain con-stant independent of the minimum and maximum flow setpoints.Controller air consumption shall not exceed .017 SCFM @ 20psi. The unit controls shall be pressure independent and shallcontrol flow within +-5% of the design flow regardless ofchanges in system static pressure. The controller shall resetthe flow, as required by the thermostat (furnished by the TC),with the same accuracy. (Optional) Controls shall be housed in asteel enclosure. A multi-point, cross flow, center averaging airflow sensor shall be located in the inlet of the terminal. The sen-sor shall amplify velocity pressure signal and provide closed-loopfeedback of actual flow to the controller. Open loop systems arenot acceptable. An identification label, piping diagram, and flowchart shall be included with each unit. Flow taps, separate fromthe sensor or controller taps shall be provided for flow adjust-ment in the field, if required.

ELECTRONIC ANALOG CONTROL SYSTEMSThe analog controls shall operate in a pressure independentmanner, and shall control air flow within +-5% of the design vol-ume. The sequence of operation is based on Anemostat ControlPackage JA-5XXX. A transformer shall be furnished and mount-ed by the unit manufacturer to step down the primary line volt-age. Controls shall be mounted in a steel control enclosure. Theelectric actuator shall be “clutch” type, and develop a minimumof 45-inch pounds of torque using an all metal gear train. Thecontroller shall maintain a constant span regardless of maxi-mum and minimum flow settings, and shall reset the primaryflow linearly with respect to room temperature changes. Thewall thermostat, factory set for primary design flow, shall be fur-nished by the unit manufacturer, for installation by the tempera-ture control contractor. The flow adjustments shall be made atthe wall thermostat utilizing a digital volt meter. An identificationlabel, wiring diagram, and flow chart shall be included with eachunit. A multi-point, cross flow, center averaging air flow sensorshall be located in the inlet of the terminal. The sensor shallamplify velocity pressure signal and provide closed-loop feedbackof actual flow to the controller. Open loop systems are notacceptable.

HVIR JET INDUCTION TERMINALSHOT WATER HEATING COILSWhere shown on the plans, hot water heating coils shall be pro-vided by the unit manufacturer. The integral hot water coils shallbe mounted upstream of the primary nozzle, in the high pres-sure chamber, by the terminal manufacturer. The coils shall be1/2” copper tubing mechanically expanded in aluminum fins, 10fins/inch. Refer to the heating schedule for capacities and per-formance requirements. Sequencing of the primary air flow andwater valves shall be coordinated between the air terminal man-ufacturer and the controls contractor. Water control actuatorsand valves shall be furnished and installed under Division _______of the specifications.

ELECTRIC HEATING COILSWhere shown on the plans, electric resistance type heatingcoils and coil controls of the slip-in type shall be furnished by theterminal manufacturer. The coil shall be field mounted in the dis-charge duct work, and shall be of sufficient distance down-stream of the air terminal to prevent hot spots and nuisancetripping. This distance is as recommended by the unit manufac-turer. Interconnections between the terminal controls and theelectric coil shall be performed by the temperature controls con-tactor. All coils shall be UL or ETL listed, and include an air prov-ing switch, primary disc type automatic reset, hi-limit, secondaryhi-limit fusible links, magnetic contactors and/or PE switchesper step, grounding terminal, door interlocking disconnectswitch, and circuit fusing on heaters exceeding 48 amps. Awiring diagram shall be permanently affixed to the coil. Refer tothe coil schedule for heater requirements.
