1.1 PRINCIPLE OF OPERATION

The operation of a desiccant dehumidification system is driven by two countercurrent air streams flowing through the desiccant wheel. In the occupied mode,outdoor air (less than 25% of total air flow) and return air are drawn through thefilter, the process fan, evaporator coil (where it is cooled and some moisture isremoved by condensation on the coil), and the desiccant wheel (whereadditional moisture is adsorbed). The dehumidified air is provided to theconditioned space. Outdoor air passes through a filter, the condenser coil, thedesiccant wheel (where moisture is desorbed), and then through theregeneration fan before being exhausted to the exterior of the building. Theemergency return air damper can be used to modulate building pressure byopening to exhaust building air through the regeneration side of the unit toregeneration fan and exhaust.

When in the unoccupied mode, the unit closes the outdoor air damper for the airintake. Return air is drawn into the dehumidification section of the unit,dehumidified and returned to the conditioned space.

In the High Carbon Monoxide/Dioxide mode the unit dampers switch and theprocess section takes in 100% fresh, outdoor air and passes it through theevaporator coils and the desiccant wheel and delivers it to the space. Thesecond refrigeration circuit will run when outdoor enthalpy is above 28 BTU perpound of air. The regeneration air inlet dampers will switch to using return air(with the capability of adding some outdoor air if condensing temperatures rise)and will exhaust the return air out of the building.

The unit also has hot water heating coils for winter operation.

1.2 DESIGN

The galvanized metal frame of the 4000 DES/DX and all of the componentsused in the design are of solid construction and selected to withstand ruggeduse in a wide variety of applications. The interior of the 4000 DES/DX is laidout to minimize pressure drop through the system and to reduce the overall unitsize. The blowers have a backward inclined design for high pressure, high flowoutput. The blower motors are provided with variable frequency drives.Maximum fan speed settings can be adjusted to optimize unit for system in whichit is installed.

The desiccant wheel can be removed from the side of the unit after removing thedrive belt and the bolts holding the shaft collar.

6

The desiccant wheel has a 50/50 split between process and regeneration inorder to allow for low temperature operation. The drive system is a belt driveand gear motor. The desiccant wheel has a flexible brush seal system on theperiphery and silicon bulb on the face to minimize cross leakage.

The regeneration fan has a 7.5 HP, 3 phase, 460 Volt motor and is rated up to6500 cfm. The process fan has a 7.5 HP, 3 phase 460 Volt motor and is ratedfor 5000 cfm. The process frequency drive is set to run from 20 to 70 hertz fornormal dehumidification but can be adjusted up or down as necessary to obtainthe required 5000 cfm at the static pressure required. A control loop in theAutomated Logic controller will try to maintain the flow at 5000 cfm by varyingfan motor frequency. During dehumidification operation the regeneration blowermotor frequency is controlled in the range of 30 Hz to 70 Hz to maintain theregeneration temperature at a set point of 115 °F.

The unit is approximately 102.5” wide by 82” high by 222”long. It is mounted ona 10 gage galvanized steel box frame and has lifting lugs on all four corners forboth sections. The unit is designed to be lifted as one complete unit and set ona curb. Return air (2), supply air, and outdoor air (2) and regeneration exhaustair are routed through ducts attached to the top and/or sides of the unit asrequired.

2.0 INSTALLATION

The NovelAire 4000 DES/DX Desiccant Dehumidifier is designed to be a stand-alone unit on the roof or in an equipment room. The 4000 DES/DX outdoorintakes and exhausts are located as shown in figures 1 and 2. Considerationshould be taken concerning the location of the outdoor intake for the building toprevent the fresh air intake from being too close to any exhaust ducts thatalready may be present on the roof or ground. Consult the unit drawings foractual duct location and sizing.

IMPORTANT – The 4000 DES/DX is designed to supply air at up to 2.0” H2O. Ifthe system pressure drop in the ducts is higher than this, air flow will be impededand unit performance will be affected. Regeneration and exhaust fans are sizedfor 1.5” system static pressure.

It is recommended that the 4000 DES/DX be installed so that the control paneland power connections are easily accessible. The unit is designed to allowaccess to the wheel from the side panels on the process side of the unit. Insurethat unit has adequate clearance when choosing an installation site.

The unit is designed to be connected to 460 volt 3 phase power with a groundwire. The unit uses 24 VAC control power internally. A separate grounding wire

7

should also be used. Observe all local electrical codes when connecting unit.Power is connected to the main switch.

The unit comes with connection points for the BACNet controller which iscapable of communication with Building Automation Systems using the BACNetMS/TP network protocol.

The unit comes with a drain line for the coil. The drain line should be installedwith a “P” trap to maintain at least 4” of water in the trap. This will prevent anyair leakage through the drain line and allow proper condensate drainage.

Drain Line Connections

Drain line

Make sure that drain linehas proper “P” trapsinstalled to prevent airfrom being blown out theunit. Trap should have aseal leg of at least 4”H2O. Failure to do so will result in water being retained in the drain pans andleaking inside the unit.

Note: The unit is shipped with the R-410A refrigerant. It takesapproximately 14 pounds 2 ounces (6.05 kg) of refrigerant to recharge thedual compressor circuit and 12 pounds 6 ounces to charge the singlecompressor circuit. Use instructions in Appendix A.

Refrigerant connections and high/low pressure switch are located in theregeneration air intake section by the compressors.

3.0 OPERATION AND CONTROL

The control panel for the 4000 DES/DX is located on the side of the unitadjacent to the supply air outlet and hot water coils. The power is brought intothe unit through a conduit connection on side of the control box. A pilot hole hasbeen provided and will be enlarged to accommodate the conduit size used. Aseparate conduit should be used for control wiring to TB5 control powerconnections, including the emergency stop (provided by others). Once the 4000DES/DX is connected to the proper power source, drain line, ducting, andcontrol wiring, it is ready to run. The 4000 DES/DX is controlled by signals fromthe BACNET network and/or a remote keypad connected to the unit. The unitmeasures the outdoor temperature and humidity, calculates the inlet enthalpyand determines which operating mode is appropriate. It also receives anoccupied/unoccupied signal that determines the source of the air stream to bedehumidified.

The operating sequence is detailed in the attached appendix. In summary, theunit will operate in one of the following modes:

1. Dehumidification mode, occupied2. Dehumidification mode, unoccupied3. High CO/CO2 Ventilation (occupied or unoccupied) If outdoor enthalpy is above 28

BTU/pound, the second refrigeration circuit will operate.4. Unit has hot water coils for heating when necessary.

3.1 CONTROL

The 4000 DES/DX is controlled by an Automated Logic control system consistingof two SE6166 modules. The control logic printout is included in the appendix.

The 4000 DES/DX has a high and low pressureswitches which will stop the unit from running if theeither the pressure is low for more than threeminutes or the high pressure trip point of 500 psig isreached. The switch will have to be manually resetbefore the unit will restart. Setting high pressuretrip higher than 500 PSIG may result incompressor damage.

The unit uses 24 VAC control power for all the run relays for the frequencydrives and the compressor contactor. This power will be disabled anytime adoor is opened in compartments containing rotating equipment for safetyreasons as well as for high or low refrigerant or high water in drain pans.

3.2 OPERATION

3.2.1 First Time Start Up of the 4000 DES/DX

1. Be sure that there are no obstructions to the free flow of air into or out of theunit.

2. Insure that drain line is connected to the unit.3. Insure that main unit is charged with R-410A refrigerant according to

Appendix A. Unit is shipped with charge unless otherwise noted.4. Insure that unit has been properly wired to 460 volt, three phase power. If

the phase is wired incorrectly, the rotation relay will keep the compressorfrom running in the wrong direction and keep the desiccant wheel fromcoming on. If power is corrected correctly, the green light on the relay willcome on when the compressor circuit breaker is on. To correct, simplyswitch two wires at the disconnect switch to change direction of rotation. The

14

variable frequency drives will rotate fans in correct direction no matter whichorder the main power lead are connected.

5. Insure that the BACNET is connected correctly and addresses are correct.6. Turn on all circuit breakers for the unit. Control lights should be lit on the

SE6166 controllers.7. Connect the SE 6166 to the control network. (See specific instructions

provided with SE 6166) for settings and connection points.8. The unit is now ready for routine operation and can be started using the

BACNET system.

3.2.2 Normal Sequence of Operation of the 4000 DES/DX

GENERAL: The unit is a 100% return air unit designed to precondition anddehumidify the return air being introduced into the air stream to a conditionedspace. The unit is capable of mixing up to 25% outdoor air with the return, whichis controlled by a damper. The unit is intended to operate year around toprovide humidity control on the mixed air. The unit is controlled by anAutomated Logic controller system.

Refer to attached sequence of operation in Appendix for furtherinformation on the normal sequence of operation.

4000 DES/DX Unit Description

The unit consists of a main refrigeration loop with tandem compressors,condenser, TXV valves and evaporator coils and a desiccant wheel which isregenerated with the condenser heat from refrigeration circuit. There is secondrefrigeration loop that runs when the unit is in High CO/CO2 mode and taking in100% outside air. The condensing temperature and compressor amps aremonitored and airflow through the condenser is controlled by a variablefrequency drive directly coupled to the condenser fan impeller. The condensingair leaving temperature is controlled in the range of 110 ºF to 125 ºF by thetemperature controller as required for regeneration of the desiccant wheel.During startup, the compressor amps should be monitored and not allowed toexceed preset maximum amps. Should amperage exceed maximum amps, theregeneration fan should be increased to maximum flow until condenser leavingair temperature is below set point and compressor amps are below maximumamps.

In occupied mode, 25 % fresh outdoor air mixed with 75% return air passesthrough filters, the process fan, and the evaporator coil. It then passes throughthe desiccant wheel and the hot water coil before being discharged to theconditioned space. If discharge temperature goes below 55 ºF, the hot waterheater can be used to raise the discharge temperature.

When a high CO/CO2 condition occurs, the unit will be commanded by the BASto run in high CO/CO2 mode. Dampers will change to pass 100% outdoor airthrough the process side of the unit and discharge return air through theregeneration side of the unit. If outdoor enthalpy is above 28 BTU/pound dry air(actual level may vary by installation), the second refrigeration circuit willoperate to reduce the supply air enthalpy and moisture content entering thebuilding.

Moisture is removed by the evaporator coil when its refrigeration circuit is inoperation and then by the desiccant wheel. The following is the sequence inwhich the refrigeration circuits will run during calls for operation during eitheroccupied or unoccupied modes. The unoccupied mode is an optional mode thatcan provide either dehumidification or heating.

SEQUENCE OF OPERATION –4000 DES/DX Version 4 3/9/2011

GENERAL: The unit is a return air unit designed to condition and dehumidify the return airbeing introduced into a warehouse or storage building. The unit is intended to operate yeararound to provide humidity control of the return air. The unit has the capability to also processup to 20% outdoor air to provide additional ventilation. The unit is configured with anemergency ventilation mode that will provide 100% outdoor air and use the return air forcondenser fan operation when a high carbon monoxide (CO) level occurs in the storage space.The unit can also operate in an unoccupied dehumidification mode which will not introduceoutdoor air for ventilation. The unit will be controlled by an Automated Logic controller systemconnected to BACNet network.

BAS Signal Inputs: The unit will be capable of receiving the following signals from theBuilding Management System (BMS) controller.

1. Enable Command2. High CO Level Ventilation Command3. Operating Mode Off/Dehumidification/Heating4. Building Temperature5. Building Humidity6. Emergency Shut Down Signal for Smoke or Firestat7. Occupied/Unoccupied Signal8. Manual Stop Signal

4000 DES/DX Unit Description

The unit consists of two refrigeration loops with compressors, condensers, TXV valves andevaporator coils and a desiccant wheel which is regenerated with the condenser heat from thelarger refrigeration circuit. The condensing temperature and compressor amps are monitored andairflow through the condenser is controlled by a variable frequency drive directly coupled to thecondenser fan impeller. The condensing air leaving temperature is controlled in the range of 115ºF to 125 ºF by the temperature controller as required for regeneration of the desiccant wheel.During startup, the compressor amps are monitored and not allowed to exceed a maximum amplevel to protect the compressor. Should amperage exceed the maximum amps, the regenerationfan will increase to maximum flow until condenser leaving air temperature is below setpoint andcompressor amps are below the setpoint amp level.

In occupied mode, up to 20 % fresh outdoor air is mixed with return air after passing throughfilters. The damper position of the outdoor air will control the amount of outdoor air providedand will have to be setup during startup balancing. The mixed air then passes through theprocess fan and the emergency and main evaporator coils. It then passes through the desiccantwheel and the hot water coil before being discharged to the conditioned space. Outdoor air issupplied to the regeneration side of the unit to remove heat from the condenser. A control loopis provided that will allow the return air damper to control building static pressure. The staticpressure signal is provided through BMS system, as it is impossible to control building static bysensors inside the unit due to filter, wheel and coil pressure drop effects. If building static ismeasurement is not available, then an additional pressure sensor will have to mounted remotelyfor each unit.

The unoccupied mode is the same as the occupied mode except that the outdoor air damper isclosed and the return air damper connected to the regeneration stream is closed.

The Emergency Carbon Monoxide mode closes the return air damper on the process side andopens the outdoor air damper 100%. The outdoor air damper on the regeneration side of the unitcloses and the emergency return air damper opens 100% to provide ventilation of the space. Theemergency cooling circuit will energize to provide additional cooling. If evaporator coil leavingtemperature going to the desiccant wheel drops below 40 °F, the emergency refrigeration circuitwill cut off to prevent coil freeze up and will not come back on until Emergency CarbonMonoxide mode is reset. If necessary, the regeneration outdoor air damper may modulate opento control compressor amps for the emergency circuit.

The following page contains a summary of the sequence for each mode of operation.

Enable, Occupied Command1. Unit will energize and2. Process Return Air Damper opens and Process Outdoor Air Damper opens to preset

position (set during startup balancing).3. Regeneration Outdoor Air Damper and Exhaust Damper open. Regeneration Return Air

Damper may modulate to provide relief air from space. Maintain close to neutral spacepressure by utilizing pressure controller. (Pressure input from BAS?)

4. Unit will energize process fan.5. Unit will energize regeneration exhaust fan.6. Desiccant wheel will start up.7. Compressor(s) will start up.8. Temperature controller will start controlling condenser air leaving temperature by

controlling regeneration fan speed.9. Post heating will function as necessary to control leaving air temperature.10. When required, regeneration return air damper will modulate to control building pressure

based on signal for building static pressure sensor signal (provided by others) from BMS.If building static is measurement is not available, then an additional pressure sensor willhave to mounted remotely for each dehumidification unit.

Enable, Unoccupied Command1. Unit will energize and2. Process Return Air Damper opens and Process Outdoor Air Damper closes.3. Regeneration Outdoor Air Damper and Exhaust Damper open. Regeneration Return Air
