Introduction

Water-Source Vertical High-Rise

The 3/4-ton through 3-ton vertical high-rise water-source heat pump is a floor mounted, “furred-

in” unit, designed to be hidden from view behind drywall to blend with the room’s natural decor.
In multi-story buildings, the units may be stacked one on top of the other to minimize piping and
electrical costs.Supply, return and condensate riser piping may be factory mounted to simplify job
site installation of the equipment.

The high-rise configuration is often used in hotels, dorms and assisted living facilities where a

single unit could provide comfort to a single or multiple room dwelling. Because the units are
mounted directly in the space, ductwork is optional.

All water-source heat pumps are commissioned, tested and quality certified prior to leaving the
factory.This assures global quality standards from controls, water, refrigeration, and aesthetics to
the building owner and installing contractor.

Key features of the water-source, vertical stack heat pump include:

1. Removable/replaceable chassis 8.

Features and Benefits

Unit Description

The vertical high-risewater-source heat pumpis a floor mounted configuration available in a ¾ ton,

1 ton, 1¼ ton, 1½ ton, 2 ton and 3 ton sizes.

The unit cabinet may be ordered for early shipment to aid in early installation of drywall, plumbing

and electrical. See “Model Number Descriptions,” p. 14.The cabinet design is available in either an
88-inch height (free discharge) or 80-inch height (ducted) configuration. As many as 3 supply-air
discharges are available for the 1¼ ton-3 ton, free discharge cabinets to provide multiple supply­air through one unit.

Air distribution is made through a rigid bar type extruded aluminum grille mounted to the
sheetrock. It is both durable and attractive in design.

The return-air panel is a hinged acoustical door, see Figure 1, p. 4.The door allows for easy access

to the unit’s filter and for maintenance of the equipment.

The hinged acoustical panel provides greater sound attenuation, and is mounted flush to the wall.
This panel is easily removed for filter maintenance or chassis removal through the magnetic catch

door. An optional tamper proof latch is available on the hinged door design to impede access if
required.

Figure 1. Return-air flush mounted hinged door

Blower/Motor Assembly

The unit’s blower/motor assembly includes double width, double inlet (DWDI) blower with direct

drive PSC motor or optional ECM motor for improved efficiency and power factor. It may be easily
removed for cleaning or service after removal of the unit chassis.The PSC motor is a multi-speed
design, factory wired to high speed or low speed (order specific).The tap will be wired and capped
inside the unit control box for easy field convertibility.The ECM motor is programmed to provide
four constant CFM profiles and is shipped on Profile B – the rated CFM of the unit.To change the
PSC speed tap or the ECM CFM profile, see installation manualWSHP-SVX03*-EN for instructions.

Controls

Standard controls include a 24V, micro-processor Deluxe controller for a wall-mounted thermostat
option.The thermostat is typically placed above the return-air door. Even though the thermostat
is considered to be unit mounted, the thermostat is mounted to the dry-wall that covers the front
of the unit.

4 WSHP-PRC020D-EN

Features and Benefits

Thermostat selections are provided in the “Thermostats and Zone Sensors,” p. 55 section of the

catalog.They are available in manual or automatic changeover options.

The deluxe controller includes relays for: anti-short cycle compressor protection, random start

delay, brown-out protection low pressure time delay, compressor delay on start and night setback
control.These extended control features offer greater system performance to extend the
equipment’s life.

Figure 2. Deluxe control box

TheTracer™ ZN510 controller (option) is provided on the vertical stack design for direct digital

control (DDC) systems.This controller offers the building owner innovative ways to optimize
heating and cooling energy for the building. Faults and sensors include: random start delay,
heating/cooling status, occupied/unoccupied mode, and fan/filter status.

Figure 3. ZN510 control box

TheTracer™ Loop Controller (TLC) may be added to either the Deluxe controls or the ZN510

controls to maintain system loop operation. See WMCA-IOP-1 for more information on the TLC.

The ZN510 controller may also be applied with theTracker and Summit building management

systems to further enhance system operation.

Non-fused switch and fused entrance block may be factory added to the equipment to save
installation time of these components in the field where local building codes allow.

Deluxe 24V Electronic Controls

General alarm is accomplished through the lockout relay and is usedto drive light emitting diodes.

This feature will drive dry contacts only, and may not be used to drive field installed control inputs.

Factory Installed Flow Control

Optional factory mounting of the isolation valve and flow control valves is available to speed field
equipment installation, and help provide optimum water flow balancing support.

Refrigeration Section

The unit’s compressor is a highly efficient, hermetically sealed with internal vibration isolation.

External isolation is provided between the compressor and mounting plate tohelp reduce radiated
noise that is typically associated with compressor start.

The air-to-refrigerant coil is easily accessible for cleaning purposes behind the unit’s removable

return-air door/panel.

The water-to-refrigerantcoil is acopper or cupro-nickel (option)co-axial tube-within-a-tube design.
The inner-water tube is deeply fluted to enhance heat transfer and minimize fouling and scaling.
The outer refrigerant gas tube is made from steel material.The coil is leak tested to assure there

WSHP-PRC020D-EN 5

Features and Benefits

is no cross leakage between the water tube and the refrigerant gas (steel tube) coil.The ½” (009/
012/015/018) and ¾”(024/036) threaded water connections to the water-coil are available on the
exterior chassis top.A flexible hose connectionwith shut-off istypically used between the riser and
water-coil in/out connections on the chassis to reduce water vibration.

The refrigerant flow metering is made through a thermal expansion valve (TXV).TheTXV allows

the unit to operate with an entering fluid temperature from 25°F to 120°F, and an entering air
temperature from 40°F to 90°F.The valve precisely meters refrigerant flow through the circuitry to
achieve desired heating or cooling.

Unlike cap-tube assemblies, theTXV allows the exact amount of refrigerant required to meet the
coil load demands.This precise metering increases the over-all efficiency of the unit.

The unit’s reversing valve is piped to be energized in the cooling mode. All vertical high-rise units

ship in a heat pump configuration with a system reversing valve.

Supply/Return/Condensate Risers

Supply, return and condensate risers are available as a factory mounted and shipped option.The
risers are constructed from type L or M copper.The top of each riser is swaged to accept the same
size diameter riser from above.This helps facilitate installation of the water supply, return and
condensate to and from the unit. Insulation may be factory installed or field installed per order
selection.The insulation helps keep moisture from forming on the pipes and damaging building
construction.

The riser length may be ordered as standard in 96” to 120” lengths. See “Equipment Risers,” p. 9

for riser application information.

Unit Safety

All unit safety devices are provided to help prevent compressor damage. Low pressure switch and
high pressure switch are added to help protect the compressor operation under a low charge (40
psig) or during high discharge (650 psig) pressures. In cases where a low charge, or excessive loss
of charge occurs, each compressorcomes equipped withan overload device tohalt the compressor
operation.

A safety lockout provides the mechanical communication of the low and high pressure switches to
prevent compressor operation if the unit is under low or high refrigerant pressures, or during a
condensate overflow condition.The lockout relay may be reset at the thermostat, by cycling power
to the unit or through a LonTalk™ front end device (ZN510 control option).

Application Considerations

Advantages of Geothermal

The advantages of a geothermal heat pump system can literally decrease heating and cooling

operating costs by 30%-40%.The units are durable, and typically last longer than conventional
systems.They are protected from harsh outdoor weather conditions, because the unit is installed
indoors and the loop underground. According to ASHRAE, the estimated service life for a
commercial water-to-air heat pump is 19 years.

Geothermal heat pumps have fewer mechanical components, making them more reliable and less
prone to failure.

Geothermal heat pumps work toward the preservation of the environment by reducing the
environmental impacts of electric power generation.

Flexibility

The vertical, high-rise water-source heat pump system is versatile for installation in boiler/cooling

tower applications, as well as ground-source (geothermal) applications.The system typically
employs a central pumping design.The central pumping design involves a single pump design,
usually located within a basement or mechanical room to fulfill pumping requirements for the
entire building system. An auxiliary pump is typically applied to lessen the likelihood of system
downtime if the main pump malfunctions.

Furring-In the Unit

The vertical high-rise water-source heat

pump is designed to be a furred-in
application. Dry-wall (sheetrock) is attached
to furring studs (not unit cabinet) until the
entire cabinet, exceptthe front access panel,
is enclosed. Access to the unit is made
entirely through thefront panel which spans
approximately one-half of the unit height.

The dry-wall enclosure allows the unit to

blend in with the decor of the room. If
renovations are needed, the drywall portion
of the unit can simply be re-papered or
repainted with the remainder of the room.

With careful design, the high-riseWSHP can

be incorporated into a room design, while
occupying minimum floor space.

Installation Tips

When installing a high-rise water-source heat pump, there are specific installation requirements

that should be taken into consideration.These include:

• Noise control

• Riser location

• Furring-in the unit

Sound Attenuation

The high-rise heat pump is better suited for acoustically sensitive water-source heat pump

applications than other water-source products. Compressor and water noise are attenuated by the
filter panel, sheet rock and the acoustically lined door. Air noise is silenced through the extended
and insulated duct portion at the top of the vertical cabinet.

Equipment Installation

The vertical high-rise unit is versatile in design to fit numerous applications. It is typically applied

to dorm rooms, hotels and motels where multiple supply air configurations may be required for
individual tenantheating and cooling.The equipment requires little space, and is tucked away from
sight, and rough handling.The vertical stack design is economical to install, requiring no ductwork
for air supply.The riser design may be stacked one on top of another for multi-story applications,
or shared between two units (see example B) when architectural design permits. Because the
chassis is removable, serviceability to the equipment is enhanced. If service does become a
requirement, the chassis is simple to remove from the cabinet, replaced with a back-up chassis,
then repaired off-site at a convenient time.

Application Considerations

Equipment Risers

The riser provides an easy way to facilitate the water flow

through a multi-story building and the high-rise heat pump.The
high-rise heat pump is best applied to a building with identical
zones on each floor, and zones that are typically small. An
example building might include a hotel, dorm, condominium or
assisted living facility. With these types of buildings, the riser
column (external to the unit cabinet) can be stacked one on top
of the other.The piping installation for the entire HVAC system
becomes very simple to install because it is pre-measured, and
pre-fabricated at the factory.

Factory risers are available asType K (design special), L
(standard design), and M (standard design).The differences
between these types of materials is the wall thickness of the
copper. Table 1, p. 9 shows the wall thickness for the most
common diameters ofrisers. Itis recommended formost jobs to
use type L or Mcopper.Type Krisers are generally notnecessary
for most high-rise heat pump applications.

The riser design contains threaded stubouts to facilitate

connection of the supply and return risers to the hose kits.The
hose kits are then connected to the water-in/out of the unit’s
chassis.

Note: Supply/return/drain risers that are ordered and supplied

through the factory may be ordered as insulated.

Drain risers aregenerallymade of typeM copper.If copper, drain
risers are used, the risers should be insulated since the typical
temperatures of condensate may cause the riser to sweat.

Note: Pressure ratings for risers are typically greater than the maximum pressure rating of the

coaxial water-to-refrigerant heat exchangers.This is true with exception ofType M copper
in a 3" diameter.The maximum pressure rating forType M, 3" diameter copper is 380 psig.
All other diameters forType M copper, and all 1" through 3"Type L copper are greater than
the 400 psig rating on the coaxial water-to-refrigerant heat exchanger.

Riser Sizing

The proper selection of riser diameter is critical when designing a cost effective job. If the riser

diameter is too small, the flow of water to the heat pump may be restricted, making the pumping
power requirement excessive. On the other hand, if the riser diameter is too large, the cost of the
equipment may become unnecessarily high.

To determine the riser size, calculate the flow at a particular riser. Riser columns will begin with

large diameters at the bottom of the column and decrease diameter as the water travels up toward
the top floor.The GPM at the first floor is determined by totaling the GPM of all the units on the
riser column.The GPM for the second floor is then determined by taking the total GPM and
subtracting the flow from the first floor.

The proper size of the riser is determined by calculating the velocity of the water in the riser.The

maximum water velocity that a riser should experience is about 6 or 7 feet/second. Table 2, p. 10
can be used as a quick reference chart fordetermining the maximum GPMallowed for a given riser
size. Riser flow diagram can be found in the
used to calculate the precise water velocity for a given riser diameter and flow.

Application Considerations

Riser Size Example

Assume a sixstory building is servedby a high-rise water-source
heat pump.When referencing the catalog, determine each high­rise heat pump uses 3 gallons per minute to meet the required
capacity of the 1-ton unit. What is the minimum riser diameter
that can be used on each floor?

With this arrangement, determine the volume of water used at
each floor is 3 GPM.The top floor riser therefore only needs to
be sized for 3 GPM. Referring to Table 2, p. 10, we know that a 1­inch type M riser can handle up to 16 GPM, therefore the riser
size is determined to be 1-inch.

The first floor will see 18 GPM through the riser. Since 18 GPM

will result in more than 6 ft./second in a 1” riser, it would be
advisable to move to a 1¼” riser.

Piping Layout of the Riser

Two methods may be used when piping a riser column.These

include direct return or reverse return.

Advantages may be seen in both types of piping methods. For

a direct return installation, the riser system is straightforward
leaving little confusionabout properly sized risers.Thisprovides
a more cost effective advantage during the installation process.

The disadvantages of this system is the pressure drop.The total

pressure drop on the unit forthe sixth floor ismuch greater than
the total pressure drop on the unit for the first floor.This means
that the riser column will require balancing from floor-to-floor
during installation.

Piping advantages for the reverse return system include the
ability to design the riser column so that the total system
pressure drop through each unit is equalized.The overall
pressure drop is also lower, allowing some energy savings
potential.This piping method however does not eliminate the
need for proper balancing at each unit.

The disadvantage of this system relates to cost and complexity.
The reverse return method typically costs more because of the

additional pipe required for each riser column.

Central Plant Control

Proper central plant control is critical to the operation of a water-source heat pump system. Loss
of waterflow or loop temperatures outside of the recommended range will severely impact the
operation of the equipment.The following should be followed as minimum operational
recommendation for the central plant:

• Heat rejector control (i.e. closed circuit cooling tower, or geothermal loop)

• Heat adder (i.e. boiler or geothermal loop)

• Circulating pumps

• Sensing elements

WSHP-PRC020D-EN 11

Application Considerations

Heat Rejection through a Closed Circuit CoolingTower

Cooling towers serve to reject heat from the condenser water loop to the atmosphere.Two types
of cooling towers are used with water-source heat pump systems: open or closed-circuit.The
towers themselves are different, but when an open tower is used in conjunction with a water-to­water heat exchanger, the control of the two tower types is essentially the same.

Control for the closed-circuit cooling towers may be made with aTrane®Tracer™ Loop Controller
(TLC). With the TLC, up to four stages of cooling tower control are possible.

When the loop supply temperature is 4°F below the loop supply high setpoint, the first stage of

cooling is initiated by opening the closure dampers on the cooling tower.

At 2° F below the setpoint the next stage of cooling is initiated which is the starting of the tower’s

circulating pump. If the amount of heat rejected by the first two stages is not enough, the loop
temperature will continue to rise.When the temperature reaches the loop supply high setpoint,the
next stage of cooling is initiated.This is the first stage of cooling tower fans.

The differential between the stages now become 3°F and the temperature must remain above the

differential for three minutes. Up to three individual fan stages may be sequenced or the second
stage of fan can be the high speed of a multi-speed motor.

There are five different fan arrangements that theTLC supports: A single fan with a single motor,

a single fan with dual motors (pony motors), a maximum of three fans with a maximum of three
motors, a variable speed fan with a field supplied variable frequency drive, and a single multi­speed motor.

Multiple cooling towers can be supported only if the cooling towerstages are controlled in parallel.

Boiler Operation

TheTLC will operate a boiler and the mixing valve respectively. Boiler control is traditionally

controlled by a separate boiler controller, provided by the boiler manufacturer.The boiler mixing
valve will control the mixture of the boiler water into the main loop to achieve the desired loop
supply water.

When the loop temperature falls below the low loop-supply setpoint, theTLC enables the boiler.

The ideal arrangementis for the boiler tohave its own bypass loopso the boiler pump can circulate

water through the heat exchanger. The boiler will maintain the temperature of the water to the
desired setting in the packaged boiler control.

The three-way mixing valve is controlled by theTLC to add heat to themain loopby mixingin water

from the boiler loop. A proportional-integral-derivative algorithm controls the valve. The boiler is
not disable until the main loop temperature is 5°F greater than the low loop supply setpoint for
more than 5 minutes.

TheTLC will also monitor the boiler loop temperature and provide an alarm if the temperature is

below the boiler loop low limit after 30 minutes of run time.The TLC will provide an alarm if the
boiler loop temperature exceeds the boiler loop high limit after 30 minutes continually.

Facilities Management

Water-source heat pump systems are naturally decentralized; thus they inherently provide

individual zone control.Typical installations use mechanical thermostats to provide localized
control. Central plant control is typically handledby a control panel located in the main mechanical
room. Minimal coordination is usually required between the central plant and the individual water­source heat pumps for successful operation of the system. A direct digital control system is
recommended to help support coordination efforts between the central plant and the individual
water-source heat pumps.This enhanced coordination can result in reductions in operating cost
of the entire system.The following items are typical of the additional coordination: Night setback
and setup; After hourusage for tracking and billing;Pump cycling foroccupied/unoccupied control;
Zone scheduling; Maintenance reporting for monitoring unit fault conditions;Trend logging of the
system water temperatures;Monitoring of systemlevels for items such as waterflow, temperature,
faults, heat rejector status, heat adder status and circulating pump status.

Selection Procedures

Model Number

Two model number designators have been defined for the cabinet configuration, and the chassis

configuration. Both model numbers require input for the order to be complete and built to
specification.

Typically the vertical stack equipment ships in two sections. (1)The cabinet and riser section ship

first to allow the contractor to furr-in the equipment during sheetrock installation, and (2) the
chassis (refrigeration/water) section ship approximately two to four weeks later eliminating
storage requirements of the chassis and possible damage at the job site while waiting for
installation. For this reason, there are two model number designators specific to the unit chassis,
and the cabinet for the equipment.
