OPTIONAL FEATURES

The direct drive plenum fan provides high performance and reliable air delivery for de-manding applications. The design allows service personnel to directly measure unit CFM from the inlet ring. This feature insures unit & building air balancing. The slide out design allows quick inspection of the fan system. The supply fan utilizes an ABB variable fre-quency drive allowing precise fan modulation. The selection software calculates the unit’s actual brake horsepower and RPM that meet the requested CFM at the given external static pressure and internal static pressure conditions. The drive has superior standard features including swinging choke, EMC filter, control panel and coating for harsh environ-ment, All drives are tested at the factory ensuring premium quality.

FAN CONTROL

Option VFC3: Duct Static Pressure Control

Sensors/Signal: Unit mounted pressure sensor; sensing range 0 -2.5” w.c.; 24 Vac, 0-10V signal; ± 1% FS accuracy; 1/4” barb connections. Requires field installed 1/4” pneumatic tubing to the ductwork located 2/3 down the duct.

Sequence: Whenever the supply fan is running in any mode, the fan speed varies to maintain the user selected duct static pressure setpoint. (Default 1”, adjustable range 0-2.5”) When the supply fan is OFF, the VFD supply fan signal will be 0%. The control sys-tem limits the actual VFD range between a user adjusted minimum and maximum output setting with default values of 25% and 100% output - other mechanical limits may apply.

Option VFC4: Building Static Pressure Control

FORM 100.55-EG1 (1214)

Option GF4: Four Position Control from 2 External Contacts

Sensors/Signal: Quantity 2, user supplied, dry contact closures. (4 wires)

Sequence: Whenever the supply fan is ON in the occupied mode, the dampers will open to a user defined % of outside air based upon 2 dry contact closure inputs. When the sup-ply fan is OFF, the dampers will be closed to outside air.

Option GF5: Building Static Pressure

Sensors/Signal: Unit mounted pressure sensor; sensing range -0.5” w.c. thru 0.5” w.c.; 24 Vac, 0-10V signal; ± 1% FS accuracy; 1/4” barb connections. Requires field installed 1/4” pneumatic tubing to the sensing zone.

Sequence: Whenever the supply fan is called to run in the occupied mode, the dampers modulate to maintain the user selected building static pressure setpoint. The dampers are limited to 25%-100% open position. When the supply fan is OFF or in the unoccupied mode, the dampers are closed to the outside air.

Option GF8: Economizer Package with CO2

Sensors/Signal: YORK supplied, field installed, wall mount CO2 sensor. Infrared beam technology, 24 Vac, 0-10V output signal, 4 wires, ± 50 ppm accuracy.

Sequence: The dampers will modulate to the user adjustable minimum outside air posi-tion setting when the unit is in occupied mode (Default = 10%). When the CO2 sensor option is selected (input U9), the minimum damper position will be determined as follows: If the Space CO2 level exceeds the space setpoint (default = 1,000 ppm) with a 200 ppm differential (default = 200 ppm), the user adjustable CO2 value will be added to the damper position. (Default = 10%).

CO2 < 800 ppm = Active Minimum Damper Position 10%

CO2 > 1,000 ppm = Minimum Position (10%) + CO2 Addition (10%) = 20% open position.

When cooling is required via the thermostat input and the outdoor air temperature is less than the economizer temperature lockout and the economizer dewpoint lockout, the dampers will modulate using a PID from the minimum position to the maximum position to maintain the mixed air temperature setpoint. (Default = 55°F)

Intake Air Hoods

Option AS16: Outside Air Hood with permanent pre-filters

Replacement air systems should typically be specified with a motorized outside damper and interlocking safety to ensure the damper is opened prior to enabling the supply fan (when no return air path is connected). Building codes and national standards may require a motorized damper for specific airflow ranges.

Reheat Overview

REHEAT CONTROL

YORK systems are specifically designed for conditioning up to 100% outside mixed condi-tions. This is accomplished using a DX system matched to high outside air applications requirements.

Options RPLE: Low Enthalpy Dehumidification Control

Option RPHE: High Enthalpy Dehumidification Control

YORK units use a dedicated refrigerant system that precools the incoming air then directly uses the condenser waste heat to reheat the air after it passes through the packaged unit main DX system. The compact commercial grade dehumidifier provides useful precooling of the air. Because the reheat system is mechanical separate from the main DX system, the dehumidification mode provides the following 4 advantages:

• Superior part load performance: The system can operate stand alone or in conjunc-tion with the package unit’s main DX system. The system does not require low ambi-ent kits or other capacity control while delivering more than 17°F of reheat needed for the application.

• Verifiable and predictable reheat performance: The system utilized a modulating digital scroll and an independent DX system which provides predictable and stable performance.

• Simplistic service and maintained: The system can run independent of the main DX, thereby allowing service technical to properly diagnose and verify performance.

• Low energy usage compared to hot gas reheat. The dehumidification mode allows for stand alone operation and/or part load operation. The main DX system can re-main OFF or run in part load without compromising the reheat capacity. This allows for lower overall energy usage.

Reheat is typically required, in geographical areas that see a 60°F dewpoint frequency greater than 400 hours per year. In conventional systems, dehumidification occurs by chilling the air below a desired dewpoint. This typically means a 52-55°F dry bulb leaving

JOHNSON CONTROLS

FORM 100.55-EG1 (1214)

24

coil temperature (50% Rh at 75°F). However, not all spaces can accept the 52-55°F air without causing overcooling. Over cooling also has the negative affect of increasing the space relative humidity. Specifying the quality (reheat availability under all load condi-tions), control of reheat (staged or modulating) and selection of the appropriate reheat system requires a working knowledge of the refrigeration cycle and HVAC system design. Considerations for the reheat system typically fall into three application types:

Zone 8

Zone 7

Zone 5

Zone 6

Zone 4Zone 3

Zone 2 Zone 1

Constant Reheat: Applied where the space sensible and latent loads are small in com-parison to the outside air load. When the outside air load dominates the space load, a neutral air (continuous dehumidified air delivered between 70° and 75°F) approach may be preferred. Typical applications include corridors and locker rooms.

Variable Reheat: Applied where the space sensible or latent loads vary in comparison to the outside air loads. Variable sensible heat gains (solar, electric loads, occupancy etc.) affect the amount of reheat required to maintain space temperature and relative humidity. If the equipment treats both outside air and maintains space temperature (a sole source unit), a variable reheat system will be required. Typical examples include surgical rooms and “clean” rooms.

No Reheat: Applied where the space sensible load is constant and much greater than the outside air load. Typical examples include motor and telecommunications centers .

To illustrate the performance, compare the performance of a cooling-only to the cooling/dehumidifying option RPLE at 95°/78°F dry bulb/wet bulb. The dehumidification system uses a basic heat pump refrigeration circuit for dehumidification and reheat. Evaporator capacity is a small part (approximately 15-20%) of the total design capacity, allowing con-tinuous operation at low loads (between 55 and 60°F ambient dewpoint). The dehumidifi-cation system precooling evaporator coil is installed upstream of the main evaporator coil, and the dehumidification system condenser coil is in the downstream position. The up-stream precool coil tempers outside air and lowers wet bulb depression of the air entering the main evaporator coil (86.4/75.3). Heat removed from the precool coil is rejected to the downstream reheat coil (71.2/61.5 including compressor and fan heat of compression). In this mode of operation the system is configured as a stand-alone neutral air unit which conditions only the outside air to the building. If the main evaporator coil were removed, the refrigeration system would resemble a standard residential dehumidifier.

Since the dehumidification unit refrigeration circuit is independent of the main evaporative cooling coil, performance is relatively constant (13-20°F.) This translates into ease of com-missioning and verification of the high COP dehumidification system performance under mild or extreme conditions. Other package systems that use hot gas reheat must main-tain higher than needed condenser head pressures for reliable operation and adequate reheat. Under low load conditions, poor performance of hot gas reheat and subcooling reheat systems can be caused by compressor unloading. Service, diagnosis, and perfor-mance of hot gas reheat systems can be difficult to verify at conditions other than design. For equivalent reheat performance, other technologies, such as heat pipes or flat plate heat exchangers may have greater than ten times the air pressure drop of the Re-Heat coils.

Additionally, performance of the dehumidification system is independent of the main cool-ing coil, while wrap around heat pipes or flat plate heat exchangers require an active cool-ing coil for energy transfer. At part load, this system can operate in a stand alone mode to provide both dehumidification and reheat.

While the dehumidification unit compressor consumes additional energy during dehumidi-fication modes, the year round benefit of reduced fan energy will result in lower annual energy costs.

Zone Outside Air Changeover Rates

When evaluating the suitability of staged capacity control, the outside air changeover rate to the zone should be calculated. Use the formula listed below.

Reheat Overview (Cont'd)

JOHNSON CONTROLS

FORM 100.55-EG1 (1214)

26

High air changeover rates may require special control sequences, air distribution design, and cooling-heating modulation controls versus step control. As a guideline, modulation should be evaluated when the changeover rate exceeds 8 ACH (1 outside air change for every 7.5 minutes). Since heating design temperature difference is typically greater than cooling, modulation of the heating system may be more critical.

Design Temperature Difference

As design extremes increase, staging or modulation of equipment capacity becomes in-creasingly important. Examining the lowest stage or step of equipment capacity relative to the lowest load condition can indicate if capacity modulation is required.

Generally products that deliver 100% outside air quantities fall into one of three basic system types. They include:

Neutral Air: Outside air is cooled, dehumidified, and heated to room conditions (70 to 75°F).

Tempering Air: Outside air is cooled and mixed with conditioned return air.

Sole Source: Conditions both outside air and the internal building loads

Identifying the system type can aid the designer in evaluating the appropriate equipment for each application. In addition, the use of interlaced coils provide excellent part load per-formance. More importantly the reheat coil should be more than 6” away from the main DX system to prevent re-evaporation of the condensate. Re-evaporation essentially reduces the overall effectiveness of the dehumidification process.

ENERGY RECOVERY

Applications

Energy recovery systems recover exhaust air energy and reintroduce it into the condi-tioned space. The energy recovery wheel provides sensible and latent energy exchange between the entering and exhaust air streams of a building. This allows a substantial amount of the energy, which is normally lost in the exhaust air stream to be returned into the entering air. Ideal applications are areas that have cold or hot temperatures with high occupancy loads or high ventilation requirements. Energy recovery units also reduce the design loads for the mechanical cooling equipment, which can mean downsizing the air conditioning equipment. Application software is available to calculate the load reductions and provide the energy and dollar savings for all areas.

Principles of Operation

The energy recovery enthalpy wheel contains parallel layers of a polymeric material that are impregnated with silica gel (desiccant). The wheel is located in the entering (intake) air and exhaust air streams of the ventilation equipment. As the wheel rotates through each air stream, the wheel surface captures sensible and latent energy. In the heating mode, the wheel rotates to provide a constant transfer of heat from the exhaust air stream to the colder intake air stream. During the cooling season, the process is reversed. During pe-riods when the outside air is mild and energy recovery is not desired, the Stop-Start-Jog option is utilized to stop the wheel from turning, thereby providing cool outside air into the space.

JOHNSON CONTROLS

FORM 100.55-EG1 (1214)

28

Cross Leakage

In space conditioning applications, where the ventilation is operating to maintain accept-able indoor air quality, there are no contaminants in concentrations of concern. Cross leakage in the energy recovery system results in a small amount of the exhaust air, typi-cally less than 5% in balanced airflow, returning to the space. The operation cost of mov-ing this air is far less than that required for a purge sector. Do not use these units in ap-plications that have high concentrations of contaminants.

Temperature Rise

SUMMER/WINTER RPM CONSIDERATIONS

For a Heating/Cooling makeup air unit, if blower RPM is the same in winter as it is in sum-mer, SCFM will usually be substantially higher in winter than in summer. The net result is more or less capacity at design condition.

Temperature rises shown in the blower tables assume a 70°F blower temperature at sea level (standard conditions). Brake HP is shown for standard conditions and will increase with lower blower temperatures and decrease at higher altitudes. For 100% makeup air applications using indirect fired gas furnaces and electric heat, in winter the blower tem-perature is essentially the same as the outdoor temperature (motor heat may add 1 to 4°F).

To calculate temperature rise, first calculate the net BTUH output at elevation (gas) or for voltage (electric). Then use the formula:

Temp Rise =BTUH net output

x(460°F + Blower Temp)

x14.7 psi

1.08 x Blower ACFM 530°R Air Pressure (elev)

Example: Consider a JDMA-210-H400 heating/cooling 100% makeup air unit with cooling reheat. The blower is balanced for 3750 cfm in the summer with reheated air at 70°F. The goal is to maintain 70°F discharge year round. What is the temp rise in the winter with incoming air at -10°F?

It can be seen for 3750 cfm at “standard conditions”, a JDMA-210-H400 would have an 80 degree temperature rise. “Standard conditions” is sea level with a 70°F blower tem-perature.

Without considering motor heat, the blower temp is -10°F incoming air, so:

Temp Rise =324,000 BTUH

x(460 - 10)

x 1 = 68°F1.08 x 3,750 530

Note that the full fire unit discharge temperature is only 58°F when outside air temperature is -10°F.

The problem is not too little heat; it is too much RPM in the winter. To maintain a constant SCFM (air mass flow) regardless of blower temperature, a variable frequency drive or volume damper may be required.

Looking at it another way, the amount of SCFM being moved in the winter is:

SCFM = Blower ACFM x 530° xAir Pressure

(elev.)

(460° + Blower Temp) 14.7 psi

SCFM = 3,750 x530

x 1 = 4,417 SCFM*(460 - 10)

Control Sequences

GENERAL SEQUENCE

Option D21: Make-Up Air

The make-up air control system operates the supply fan, exhaust fan, intake dampers energy recovery, DX cooling and gas/electric heat to maintain a set of discharge air tem-perature control setpoints.

The unit discharge air temperatures fall within the following (3) categories

1. Unit supplies Neutral air temperature that does not affect space conditions

2. Unit supplies Cold air temperature to provide space cooling

3. Unit supplies Hot air temperature to provide space heating

The sequence is broken into (6) states of operation, (2) modes of operation per state and individual component function based upon the state and mode.

STATES OF OPERATION

1. Off

The unit supply fan and all associated mechanical equipment is OFF in this state. There are no associated sequences of operation in this state. The unit will only switch to the OFF state when the state is manually selected through the user interface device (thTune), unit display or building automation network communication point. Upon initial power, Unit OFF is the default state.

2. Alarm

The alarm state can only occur from a sequence “failure.” The unit will switch to this state from the heating, cooling or auto state. The unit will stop all mechanical operation until the “failure” condition(s) are resolved. The output will be OFF. Upon resolving the failure the unit will return to heating, cooling or auto state. Alarms can also be cleared by resting power to the unit. See alarm sequence for details.

3. Heat

From the thTune, controller display or BMS, this mode can be selected. The unit’s supply fan will run and mechanical heating, dampers and energy recovery equipment will oper-ated to maintain heating sequences of operation.

The unit will not automatically switch to other states except Unit Alarm.

4. Auto

From the thTune, controller display or BMS auto state can be selected. Upon initial se-lection of the auto state, the unit will be in a auto-heating state whenever the outdoor air temperature is below (65°F), otherwise the unit will be in the auto-cooling state. The unit will change to auto cooling/auto-heating state whenever the temperature crosses the change-over setpoint for more than (15 mins) minutes or is more/less than (5°F) beyond the setpoint.

The unit mechanical function is exactly the same in either cooling or heating state, other than the sequence’s ability to change states. *The unit switches between heating and cooling based upon outside air temperature. Space temperature does not dictate heating or cooling mode.

5. Cool

From the thTune, controller display, or BMS , this mode can be selected. The unit supply fan will run and mechanical cooling, dampers and energy recovery equipment will oper-ated to maintain the cooling sequence of operation. The unit will not automatically switch to other states except Unit alarm.

6. Test

The unit can be manually placed in a test mode for (2 hrs) hours time period from the unit mounted display only.

In the test state, all sequences of operation stop. The user can manually select all outputs to be ON/OFF or 0-100% modulated outputs.

OCCUPIED & UNOCCUPIED

When the unit is called to operate in the auto, heating or cooling state(s), the unit will func-tion in one of (2) modes: occupied or unoccupied. The unit will run in occupied or unoc-cupied mode based upon commands:

1. Internal Time Clock Schedule Selects Occupied or Unoccupied Mode.

2. Physical input point (ID4) (Contact closed = Occupied)

3. Building Automation network variable. (Lon & BacNet)

SUPPLY FAN CONTROL: OCCUPIED MODE

When the unit is called to be in occupied mode, the outside air damper will modulate 100% open. If the unit has only 100% outside air damper, the damper actuator is electri-cally interlocked to the fan start/stop such that the supply fan can not start until the damper is 80% open.
