Gentlemen:

We respectfully submit for your approval the following HVAC equipment for the subject project.

SPECIFICATION SECTION 23 74 13 – PACKAGE OUTDOOR CENTRAL-STATION AIR HANDLING

UNITS

RESPONSE TO ENGINEER’S COMMENTS DATE 10/14/14 FOR AHU-3N-OR

1. Attached is the factory drawing with arrows pointing out electrical connection points for fan motors, humidifier generator, 120v lights. Due to the custom nature and the extent of special features on this unit, this is the best drawing that can be created for this unit at this time.

2. It is assumed that the VFD’s are to be mounted in the existing pump house that contains the electrical panels.

To maintain consistency we will provide Square D drives to match the existing drives currently in the pump house.

3. The heat pipe has a Sporlan fully modulating valve in the circuit. The controller for the valve accepts either a

0-10 vdc or 4-20 ma signal. The heat can be modulated to maintain a discharge temperature or can be turned off based upon the desired sequence of operation.

4. All return, exhaust, supply connections have been labeled on the attached drawing.

5. There is no opening provided between the exhaust air section and the outside air section. An insulated bulkhead/wall divides the air streams. There was symbol that was inadvertently left on the drawing between the two air streams that was a damper. There is no damper there.

6. Fan motors will be Premium Efficiency TEFC’s.

THERMOSYPHON RUN AROUND HEAT PIPE -- TRAHP™

Typical Model: ST Mach 1 In Production

Shown above are typical TRAHP™ sections in production.

When incorporated into an air handler these TRAHP™ sections can be used to treat outside air or mixed air for proper humidity control without adding external energy. In such an application the installation becomes a Thermosyphon Run-Around Heat Pipe (TRAHP™).

These TRAHP™ sections can also be used for energy recovery when properly positioned in an exhaust air stream and the supply air stream.

Dehumidification with TRAHP™ Model: ST Mach 1:

Suggested Sequence of Control

Control Technique for Improved Dehumidification

The DDC control system or thermostat shall activate the chilled water valve or the compressor when a DX system is used to ensure the leaving air temperature of the cooling coil maintains the required dew point temperature.

The room sensors are expected to modulate the TRAHP™ control valves to maintain the desired relative humidity while the air conditioning system continues to maintain the desired room temperature.

Additional reheat may be used to supplement the reheat provided by the TRAHP™ system.

In certain applications where an air handler feeds multiple conditioned zones it may be practical to consider controlling the amount of reheat provided by the TRAHP™ System in response to a humidistat located in the return duct. The humidistat could order an increase in the heat transfer from the precool coil to the reheat coil while proportionally closing the CW control valve to maintain dew point temperature control.

An alternate strategy would be to reduce the TRAHP™ heat transfer in response to outside ambient temperature during peak cooling periods when maintaining space temperature is more important than maintaining the space humidity level.

Dehumidification With

Controllable Hot Gas Reheat:

Call for cooling:

On temperature rise, compressor #1 is energized; if temperature continues to rise, compressor #2 is energized. As space temperature is satisfied, this sequence is reversed.

Call for dehumidification:

If humidity rises above Setpoint and there is no cooling call, compressor #1 is energized and the Hot Gas Reheat Solenoid is opened. For a two-compressor unit, both compressors may be required to ensure the evaporator coil is removing moisture while the HGRH coil is raising the supply air temperature. When the call for dehumidification is satisfied, the Hot Gas Reheat solenoids can be de-energized.

During dehumidification, the room thermostat will run the air conditioner longer to reduce humidity due to load from the HGRH coil and may be permitted to lower the temperature setpoint by 1 to 2 degrees below the cooling temperature setting. However, if the cooling temperature drops below this, the compressor must be stopped and the HGRH solenoid closed.

The supply fan should also be stopped to prevent reintroducing moisture from the cooling coil.

Please note: Dehumidification only occurs when the compressors are running. The hot gas diverted from the condenser is an energy efficient method of reheating the supply air leaving the evaporator to provide air entering the duct at a lower relative humidity.

Call for heating

Cooling and dehumidifying hot gas reheat are locked out until the call for heating is satisfied.

Split System Heat Recovery TRAHP™:

General

The split system heat recovery TRAHP™ controller shall be enabled whenever the supply air is operating. The Heat Recovery System control valves shall normally be open and may be controlled in sequence to provide the required amount of heat recovery.

The controller shall monitor air temperatures and index stages of heat recovery as desired.

All stages of heat recovery shall be off during use of the economizer cycle.

Sequence

When a heat recovery coil discharge air temperature is 75 deg. F and above all heat recovery control valves shall be opened allowing heat transfer to the exhaust air.

When a heat recovery coil discharge temperature is between 52 deg. F and 75 deg. F all heat recovery control valves shall remain closed.

Upon decreasing a heat recovery coil discharge air temperature (below 52 deg. F) all heat recovery control valves shall be staged open allowing heat recovery from exhaust air.

Frost Control

The controller shall index stages of heat recovery to maintain an exhaust air discharge temperature above 35 deg. F. Upon a drop in discharge temperature below 40 deg. F the first stage of heat recovery shall be disabled. If the discharge temperature continues to drop, additional stages of heat transfer shall be disabled to maintain a minimum 35 deg. F exhaust air discharge temperature.

Vapor Line Temperature Control

When required, may be used to avoid premature condensation of vapor or to regulate the amount of vapor transfer.

The CDS valves are electronically operated step motor evaporator pressure regulating valves. Synchronized signals to the motor provide discrete angular movement, which translates into precise linear positioning of the valve piston. Valve pistons and ports are uniquely characterized, providing superb flow resolution and performance. The CDS valves are easily interfaced with micro-processor based controllers, including Sporlan supplied controllers.

Connections in Inches (mm)

The IB Series interface boards have been developed as economical compliments to the TCB temperature control boards. The IB Series is available in three basic models, IB1, IB3 and IB6, and each can accept 4-20 milliamp or 0-10 volt DC analog input signals. All are designed to allow externally supplied control signals to control one or two Sporlan step motor valves including CDS evaporator control valves, SDR elec-tric discharge bypass valves and SEI/SER/SEH electric expansion valves.

The IB1 is programmed to control any Sporlan step motor valve having 1596 steps of resolution, the IB3 is used with valves having 3193 steps and the IB6 is used on valves with 6386 steps. "Q" denotes quick response for special applications. Please contact Sporlan Valve Company. Refer to Ordering Information, page 2.

CONFIGURE the BOARD

When used with a 0-10 volt input signal, a jumper should be placed on the pins labeled CN3 as shown in the Figure 1. This is the default jumper position. The impedance for this input is 40 k ohms.

When used with a 4-20 milliamp input, the board must be matched to the impedance of the external controller. Refer to the manufacturer's literature and choose the jumper posi-tion on CN4 as shown Figure 1. Possible impedance selections on CN4 are 1,000 ohms (1k), 600 ohms, and 300 ohms.

Choose “Open on Rise” or “Close on Rise” operation using the middle two pins on jumper CN2. The jumper is stored on one pin only and will cause the valve to open as input sig-nal rises, i.e. valve is closed at 0 volts or 4 milliamps and fully open at 10 volts or 20 mil-liamp input. By placing the jumper on both pins, the operation is reversed so that the valve will be fully open at 0 volts or 4 milliamps. Other pins on CN2 have been clipped at the factory and are not used for operation of the valve.

MOUNT the BOARD

The IB Series is based on a 3.0" x 3.0" circuit card with 0.125" mounting holes, 0.25" from each corner. If desired, these mounting holes may be used with customer supplied non-metallic standoffs. The IB Series does, however, come supplied with a length of snap-in plastic track. The track should be mounted in the desired location and one side

3. The pumpdown terminals must be supplied with a “dry” contact from a switch or relay. No external power should be applied to these terminals.

OPERATION and TROUBLESHOOTING

When properly configured and installed the IB Series requires no maintenance. They incorporate a number of oper-ational features to assure trouble free service. On power-up the board will initialize by giving the valve a large number of steps to assure that the valve is fully shut. The routine will require approximately 8 seconds for the IB1, 16 seconds for the IB3 and 32 seconds for the IB6. The valve will not respond to input signals during this time.

If the valve is required to shut during operation, the pumpdown terminals should be used. When given a pumpdown signal, the board will shut the valve immediately and overdrive by 250 steps to reset valve position. On removal of the pumpdown sig-nal the valve will resume position as dictated by the external control signal.

If power is lost to the IB or wire to the valve severed, the valve will remain in its last position. Solenoid valves may be desired before the step motor valve on critical applications.

To force the valve shut during operation for test purposes, sim-ply remove the jumper from CN4 or CN3, depending on con-figuration. To resume normal operation, replace the jumper.

To allow for component tolerances, the IB will shut the valve when the input signal reaches 4.2 milliamps or .5 volts depending on the configuration.

The IB can power one or two valves. The valves will operate simultaneously and will open and close by the same number of steps. Valve wires must be connected exactly the same for both valves.

Page 2 / BULLETIN 100-50-2 of the IB engaged in the upper groove in the track. The IB is then pushed down so that the opposite side of the board snaps into the uppermost groove in the opposite side of the track.

The board may be mounted in the orientation most convenient for wiring. Location should be dry, protected and close to the 24 volt power supply and external controller.

WIRING INSTRUCTIONS and CAUTIONS

Use the chart above as a guide for wire connections. Certain precautions must be taken in wiring and operation of the IB Series.

1. The 24 volts must be supplied by a 30 VA or 40 VA trans-former not used for any other purpose. In addition, the sec-ondary winding of the transformer must not be connected to chassis ground. A single transformer may be used for mul-tiple IB boards. If this feature is used, one leg of the 24 volt supply must be connected to all of the IB boards at the 24+ terminal. The other leg of the 24 volt supply must be con-nected to all of the IBs at the 24- terminal. Please refer to Figure 2.

Incorrect wiring will cause the fuse to fail, a spare fuse is included and may be replaced with any 1 amp 250 volts delay fuse type GMC1 or equivalent. Wiring should be cor-rected before replacing the fuse.

2. The primary input of the transformer should be protected by Metal Oxide Varister (MOV) surge suppressors, sup-plied with the IB. For protection from electrical transients, connect one MOV between one leg of the input voltage of
