Hanging Device
The hanging bracket resides in the
cham fered corner of the horizontal
unit. This partially-concealed bracket
design eliminates added height,
width, or length to the product. The
brackets are factory m ounted to shorten job installation requirements.
The structural integrity of the design
helps assure no bracket deflection or
unit bowing from the unit’s w eight.
Field return-air hook-up and filter
maintenance are more sim plistic because of this innovative design. Isolation for the hanging bracket is
provided w ith a neoprene rubber
grom met design. This isolation device
helps prevent sound vibration from
reaching the structural support members of the building during com pressor start and stop. (See Figure 7 for
isolation device).
Drain Pan
The unit drain pan is com posed of
plastic, corrosive resistive m aterial.
The pan is positively sloped to com ply
with ASHRAE 62 for (IAQ) indoor air
quality conform ity.
Access to the drain pan is provided
through two access panels for cleaning purposes for all m odels. (See Fig-ure 8 for plastic drain pan).
Ref rigerat ion Piping
The unit’s copper tubing is created
fr om a 99% pure copper form atio n th at
conform s to the American Society of
Testing (ASTM ) B743 for seamless,
light-annealed processing.
The unit’s copper refrigeration system
is designed to be free from contam inants and conditions such as drilling
fragm ents, dirt, or oil. This excludes
the possibility of these contaminants
from damaging the com pressor m otor.
Compressor
The unit’s design includes a w ide variety of com pressor m otors to accommodate dedicated voltages and
tonnage sizes. The 1/2 ton through
1 1/2 ton products w ill embody a rotary com pressor design, w here as unit
sizes ranging from 2 ton through 4 ton
include a reciprocating com pressor
style, w hile the 5 ton unit contains a
scroll com pressor. These different designs allow Trane to provide the voltage variations along with noise
reduction. (See Figure 9 for reciprocating com pressor).
The larger tonnage (GEV model)
12 1/2 through 25 ton units include a
dual circuit system which incorporate
scroll com pressors.

Figure 8: Plastic drain pan
Im portant!
Although the drain pan is sloped, the
horizontal unit should be hung at a
dual angle (per local code) to provide
proper drainage of the condensate
system.
Cabinet Insulation
The cabinet insulation design m eets
UL 181 requirements. The air stream
surface of the insulation is fabricated
of a non-biodegradable source.

Co-axial Water-to-Refrigerant Coil
The unit’s internal heat exchanging
water coil is engineered for m axim um
heat transfer.
The copper or cupro-nickel seamless
tubing is a tube within a tube design.
The inner-w ater tube contains a deep
fluted curve to enhance heat transfer
and minim ize fouling and scaling. It is
available in either copper or cupro-nickel (selectable option) coil.The

WSHP-PRC001-EN9
outer refrigerant gas tube is m ade
from steel m aterial. The coil is leak
tested to assure there is no cross leakage betw een the water tube and the
refrigerant gas (steel tube) coil. Co-ax-
ial heat exchangers are more tolerant
to freeze rupture. (See Figure 1 1 for
co-axial water coil).
Compressor and Co-axial Coil
Isolation
For the 1/2-ton through 5-ton units, vibration isolation of the compressor
and co-axial water coil is accom plished by increasing the rigidity and
stiffness at the base. This platform includes double isolation to the compressor and single isolation to the
co-ax ial w ater co il. The com bination in
th e dou ble isolation provide additional
attenuation during com pressor start
and stop.
Water Connect ions
(1/2 t hru 5 -t on)
The w ater-in/w ater-out connections to
the co-axial water coil are located on
the right-hand cham fered corner of
th e uni t. The fittings are m oun ted f lush
to the cham fered wall to help lim it
shipping damage.
The w ater connection devices are constructed of copper or bronze material
and include a National Female Pipe
Thread (NFPT) junction. The connections are attached to the unit’s cham fer corner to alleviate the need for a
back-up w rench during installation.
(See Figure 1 2 for water connection
device).
Water Connect ions
(12 1 /2 thru 25-ton)
Water hookups for the larger tonnage
units are located internal to the unit to
help alleviate dam age to the water
copper during shipm ent o r job storage
of units prior to installation. Each unit
(although dual circuited) contains a
single supply and return water connection. (See Figure 1 3 for large tonnage water hook-up). Fittings for the
supply and return are internally
threaded.

Expansion Valve
All Trane w ater-source systems include an expansion valve flow metering device.
This therm al expansion valve (TXV) allows the unit to operate with an entering fluid tem perature from 25 F to 110
F, and entering air temperatures from
40 F to 90 F. The valve is designed to
meter refrigerant flow through the circuitry to achieve desired heating or
cooling.
Unlike cap-tube assemblies, the expansion valve device allows the exact
am ount of refrigerant required to m eet
the coil load dem ands. This precise
metering by the TXV increases the efficiency of the unit. (See Figure 14 for
therm al expansion valve).

Reversing Valve
A system reversing valve (4-way
valve) is included with all heating/
cooling units. This valve is piped to be
energized in the cooling m ode to allow the system to provide heat if valve
failure w ere to occu r. On ce the valve is
energized for cooling, it w ill rem ain
energized until the control system is
turned to the OFF position, or a heating cycle is initiated.
Units with the cooling only option w ill
not receive a reversing valve. (See
Figure 15 for reversing valve).
Blow er M otor
The 1/2 through 5-ton supply-air
(blow er) motor is a m ulti-speed m otor
with internal thermal overload protection. The m otor bearings are perm anen tly lubricated and sealed. Standard
motors are rated from .20 ESP. Option-al high static motors are rated from .40
to 1.40 ESP. All m otors are factory
wired to the option selected. A high,
medium , and low speed tap is provided for field custom ization on all voltages. The speed tap modification can
be m ade in the control box of the unit .
(See Fig ur e 1 6 for blow er motor).
Not e: The 3 8 0 , 4 1 5 , 4 6 0 and 575
vo lt designs are provided in a dua l
or t hree-speed version only. See
fan perform ance section for factory
ratings (Page 91).
The 12 1/2 through 25 ton GEV models
incorporate a belt driven motor selection into the design. The 12 1/2 and 15
ton units include a single fan assembly, w hile the 20 and 25-ton units include dual fan assemblies. Because
the motor sheave and the motor base
are adjustable in the field, a greater
variation in external static pressures
are available. The large tonnage units
are capable of providing 0 ESP to 3.0
ESP allow ing a higher static ductw ork
to be applied on the mechanical system w hen the application requires
extensive ductwork design. This is a
low cost alternative to purchasing, installing, and maintaining multiple
smaller tonnage units to meet the required air flow dem and for the space.
Serviceability to the m otor is made
through either of the two air-side access doors for the horizontal configuration, and through one air-side
access door for the 1/2 through 5-ton
vertical configuration. The m otor and
blow er wheel are removable by an or-if ice ring m ounted to the fan housing.
Access to the 12 1/2 through 25 ton
units is m ade through the back of unit
by way of two panels, and/or through
a side access panel if adjustm ent to
the motor belt or m otor base are needed. (See Figure 17 for motor
accessibility)
Blow er Housing
The blower housing is constructed of
non-corrosive galvanized steel. A factory-mounted ori fi ce rin g is provided
for ease of m otor serviceability on the
1/2 through 5-ton direct drive units.
All air-side panels are interchangeable
with one another for ease of field convertibility of the supply-air on the GEH
model.
A ir-Side Filter
The air-side filter incorporates a 1-inch
thick (nom inal) or 2-inch thick (nominal) disposable fiberglass option.
These filters include an average synthetic dust w eight arrestance of approxim ately 75%. This dust holding
capability includes a colorless, odorless adhesive to retain dirt particles
within the filter media after fiber contact. (See Figure 18 for filter media)

Air-to-Refrigerant Coil
The air-to-refrigerant heat exchanger is constructed of staggered
copper tubes w ith die-form ed corrugated lanced aluminum fins.
The fins are then mechanically bonded to the tubes through ex-
pansion.
The coil is placed internal of the unit design for model
GEH to assur e no fin surface dam age during shipm ent,
jobsite storage, or installation.
The internal placem ent of the coil on the horizontal con-
figuration provides an option of a dual filtration application. With dual filtration to the GEH unit, m aintenance to
the filter is significantly less than with a single filtration
system.
The m axim um working pressure for both the GEH and
GEV coils is 450 psig. It is designed for maximum capacity w ith an additional benefit of physical unit size reduc-
tion.
Coil specifications for both GEH and GEV may be found on
in the General Data section on page 48 of this catalog. See

located directly over the occupied
space.
This sound reduction package reduces
radiated noise from the cabinet. Trane
double-isolates the compressor and
single-isolates the co-axial coil in the
unit. This design absorbs the vibration
that contributes to radiated sound
For sound critical spaces, an
enhanced sound package as described in Table 2 pr ov id es add it io nal

Boilerless Cont rol/Elect ric Heat
(option)
In cooling dom inant regions where
heat may be used 15 to 30 days out of
the winter season, eliminating the
boiler m ay be an econom ical advantage to the building ow ner. Eliminating a boiler from the system reduces
costs associated with the m echanical
system installation, as w ell as the
maintenance and service of the boiler.
How can heat be provided for the few
days of the year when heat is necessary? Through the w ater-source heat
pump of course. The advantage of the
water-source heat pum p is it’s ability
to provide heat recovery w ithin the
closed w ater-loop. While some
WSHPs may be extracting heat from
the closed w ater loop, other WSHPs
may be adding heat to the closed
water loop. This creates a perfect system balance for heat sharing or movement from one space to another.
But when water tem peratures fall in a
boilerless system, and no further heat
recovery m ay be m ade via the closed
loop, heat may be added to the space
through a boilerless control electric
heat option. See Figure 20 for the
boilerless control, electric heat system

Boilerless Cont rol/Elect ric Heat
Heat ing/Cooling M ode
In heating mode, when the water tem perature falls below 55 F (factory setting), the electric heater
is energized, locking
out the compressor.
The system s electric
heat source w ill continue to be
utilized for prim ary
heating until
the loop
tem perature rises
above 60 F.
Once the
entering water tem perature rises above 60 F, the boilerless controller returns the unit to
norm al com pressor heating operation and locks out the electric heater.
This maximizes efficiency from the
unit during the few days requiring
heat from the m echanical system . See
Figure 21 for the factory mounted

Waterside Economizer (opt ion)
The beauty of the w aterside economizer is it’s ability to take advantage of
any loop condition that results in cool
water tem peratures. A prime exam ple
w ould be during fall, w int er and spring
when cooling towers have m ore capacity than required and could be controlled to lower temperatures for
econom izer support.
Another more com m on inexpensive
means of free comfort cooling includes buildings system s w here perimeter heating and core cooling are
needed. In this system , the perimeter
units extract heat from the building
loop while in the heating mode, forcing the building loop temperature to
drop. Where as, the core are of a building m ay require cooling in summer or
in winter based upon lighting, people
and equipment.
If the w ater-source system design contained an economizing coil option, the
moderate tem perature loop water circulated through a core w ater-source
system can provide an inexpensive
means to satisfy room com fort w ithout operating the water-source heat
pump’s com pressor.
During economizer m ode, fluid enters
the unit, and passes by a w ater temperature sensing bulb. This temperature sensing bulb determines whether
the tw o position, three-way valve will
direct the water through the w aterside
econom izing coil, and to the heat
pump condenser, or through the condenser only. If the water tem perature
is 55 F or less, fluid will flow into the
econom izing coil, w hile sim ultaneously halting mechanical operation of the
com pressor. M echanical cooling w ill
continue on a call for second stage
from the thermostat.
The factory built w aterside economizer is available on all GEH models, and
all 12 1/2 to 25 GEV models. The 1/2

Hot Gas Reheat (opt ion)
For space conditioning and clim ate
control, Trane provides an accurate
and cost effective dehumidification
control through a hot gas reheat option. This option is designed to accom modate unit sizes 012, 036, 060, 180
and 240.
With this reheat option, the return air
from the space is conditioned by the
air-to-refrigerant coil, then reheated
by the reheat coil to control not only
the space temperature, but to also reduce the relative hum idity of the
space. The moisture removal capability of a specific heat pump is determined by the units latent capacity
rating.
When operating in the reheat m ode
(meaning the sensible tem perature
has been m et in the space), the hum idistat signals the reheat relay coil to
energize, allowing the high pressure
refrigerant gas to flow from the (1 )
com pressor, through the (2) reheat
valve, into the (3 ) reversing valve, or
through the (4 ) reheat coil for dehumidification. A switching relay has
been provided for the reheat application to adjust the blow er motor from
norm al operation to low speed w hen
hot gas reheat is energized.
Note: Trane places an air separation
space betw een the air-to-refrigerant
coil, and the reheat coil to allow for
maximum m oisture rem oval.
Common Reheat Applications
The hot gas reheat option is designed
to support building applications requiring fresh-air ventilation units delivering unconditioned-air directly to
the space. It also provides dehum idifi-
cation to large latent load spaces such
as auditoriums, theaters and classroom s, or anyw here hum idity control
is a problem.
Do’s and D on’ts in Design
The factory installed hot gas reheat
option is only available with Deluxe or
ZN524 controls packages.
A high static blow er motor option will
be required to support the hot gas reheat option.
Water regulating valves should not be
used with the hot gas reheat option.
Trane places a therm al expansion
valve on all w ater-source heat pumps,
as well as ground-source heat pum ps,
to regulate refrigerant flow vs. w ater
flow , m aking the heat pump m ore efficient to run.
The w ater-source heat pum ps with hot

Random Start
The r andom start relay provides a time
delay start-up of the com pressor wh en
cycling in the occupied mode. A new
start delay time between 3 and 10
seconds is applied each time power is
enabled to the unit.
Ant i-short Cycle Timer
The anti-short cycle timer provides a
three m inute tim e delay between
com pressor stop and com pressor
restart.
Brow n-out Protection
The brown-out protection function
measures the input voltage to the
controller and halts the compressor
operation. Once a brow n-out situation
has occurred, the anti-short cycle
timer w ill become energized. The
general fault contact will not be
affected by this condition. The voltage
will continue to be monitored until the
voltage increases. The compressors
will be enabled at this time if all
start-up tim e delays have expired, and
all safeties have been satisfied.
Compressor Disable
The compressor disable relay provides a temporary disable in compressor operation. The signal would be
provided from a water loop controller
in the system. It w ould disable the
com pressor because of low w ater
flow , peak limiting or if the unit goes
into an unoccupied state. Once the
com pressor has been disabled, the anti-short cycle time period w ill begin.
Once the compressor disable signal is
no longer present, and all safeties are
satisfied, the control w ill allow the
com pressor to restart.
Generic Relay
The generic relay is provided for field
use. Night setback or pump restart are
tw o options that m ay be w ired to the
available relay. (Note: Night setback is available as factory wired). A n ex ter nal Class II 24VAC signal will energize
the relay coil on terminals R1 and R2.
Term inals C (common), NO (normally
open), and NC (normally closed) will
be provided for the relay contacts.
Safet y Control
The deluxe m icroprocessor receives
separate input signals from the refrigerant high pressure sw itch, low suction pressure switch and condensate
overflow.
In a high pressure situation, the
com presso r co nt acto r i s de-energized,
which suspends compressor operation. The control w ill go into soft lock-out m ode initializing a three m inute
time delay and a random start of 3 to
10 second tim e delays. Once these delays have expired, the unit w ill be allowed to run. If a high pressure
situation occurs within one hour of the
first situation, the control w ill be
placed into a m anual lockout m ode,
halting com pressor operation, and initiating the general alarm.
In a low t em perat ure sit uat ion , the
low pressure switch w ill transition
open after the com presso r starts. If the
switch is open for 45 seconds during
com pressor start, the unit will go into
soft lockout mode initializing a three
minute time delay and a random start
of 3 to 10 second tim e delays. Once
these delays have expired, the unit will
be allowed to run. If the low pressure
situation occurs again w ithin 30 minutes, and the device is open for more
than 45 seconds, the control will be
placed into a m anual lockout m ode,
halting com pressor operation, and initiating the general alarm.
In a condensate overflow

manual lockout m od e, hal ti ng com pressor operation, and initiating the
general alarm.
The g en er al alarm is initiated w hen
the control goes into a m anual lockout
mode for either high pressure, low
pressure or condensate overflow conditions.

The Tracer ZN510 and ZN524 are direct digital control (DDC) system s specifically
designed for single and dual circuited w ater-source equipment to provide control
of the entire unit, as well as outputs for unit status and fault detection. Each d evice is factory installed, com m issioned, and tested to ensure the highest level of

Each of the controller’s features and options w ere selected to coordinate with the
unit hardw are to provide greater energy efficiency and equipment safety to prolong the equipment life.
In addition to being factory configured for control of the unit fan, co mpressor and
reversing valve, the ZN510 and ZN524 controllers are designed to coordinate the
waterside of the water-source system through the Tracer Loop Controller (TLC).
If applied in a peer-to-peer com m unication environment, data between similar

linked directly to the Tracer Sum m it,
each Tracer Summit building

the Tracer ZN524 board.
Figure 32: Tracer ZN524 controller
Tracer ZN510 and ZN524
funct ions include:
Compressor Operat ion
The compressor is cycled on and off to
meet heating or cooling zone demands. Single and dual compressor
units use the unit capacity and pulse
width modulation (PWM) logic along
with m inimum on/off timers to determine the com pressor’s operation. The
com pressor is controlled ON for longer periods as capacity increases and
shorter periods as capacity decreases.
Random Start
To prevent all of the units in a building
from energizing m ajor loads at the
same time, the controller observes a
random start from 0 to 25 seconds.
This timer halts the controller until the
random start tim e expires.
Reversing Valve Operation
For co oling, the reversing valve output
is energized simultaneously with the
com pressor. It will remain energized
until the controller turns on the
com pressor for heating. At this time,
the reversing valve m oves to a
de-energized state. In the event of a
power failure or controller OFF
situation, the reversing valve output
will default to the heating
(de-energized) state.
Fan Operation
The supply air fan operates at the factory wired speed in the occupied or occupied standby m ode. When switch is
set to AUTO, the fan is configured for
cycling ON with heating or cooling. In
heat mode, the fan will run for 30 seconds beyond com pressor shutdo wn in
both occupied and unoccupied mode.
Fan Run Timer
The controller’s filter status is based
on the unit fan’s cumulative run hours.
The controller compares the fan run
time against an adjustable fan run
hours limit and recommends unit
maintenance as required.
Dat a Sharing
The Tracer ZN510/ZN524 controller is
capable of sending or receiving data
(setpoints, fan request, or space temperature) to and from other controllers
on the com m unication link. This allo ws m ultiple units to share a com mo n
space temperature sensor in both
stand-alone and building autom ation
applications.
Night Setback
The four operations of the Tracer
ZN510/ZN524 controller include occupied, occupied standby, occupied bypass and unoccupied.
In an occupied situation, the controller uses occupied heating and cooling setpoints to provide heating and
cooling to the building. This occupied
operation is norm ally used during the
daytime hours when the building is at
the highest occupancy level.
In an occupied st andbysit uat ion,
the controllers heating and cooling
setpoints are usually wider than the
occupied setpoints. This occupied
standby operation is used during daytime hours when people are not
present in the space (such as lunchtime or recess). To determ ine the
space occupancy, an occupancy sensor is applied.
In an unoccupied situation, the
controller assum es the building is vacant, which normally falls in evening
hours when a space m ay be em pty. In
the unoccupied m ode, the controller
uses the default unoccupied heating
and cooling setpoints stored in the
controller. When the building is in unoccupied m ode, individual units may
be m anually placed into tim ed override of the unoccupied mode at the
units wall sensor. During timed override, the controller interprets the request and initiates the occupied
setpoint operation, then reports the effective occupancy m ode as occupied
bypass.
In t he occupied bypass mode, the
controller applies the occupied heating and cooling setpoint for a 120
minute time limit.
High and Low Pressure
Safet y Controls
The Tracer ZN510/ZN524 controller
detects the state of the high pressure or low pressure sw itches. When a
fault is sensed by one of these sw itches, the corresponding message is sent
to the controller to be logged into the
fault log. When the circuit returns to
norm al, the high pressure control and
low pressure control autom atically reset. If a second fault is detected within
a thirty-minute time span, the unit
must be m anually reset.
Condensat e Overf low
When condensate reaches the trip
point, a condensate overflow signal
generates a diagnostic w hich disables
the fan, unit water valves (if present),
and com pressor. The unit will remain
in a halted state until the condensation
returns to a normal level. At this tim e,
the switch in the drain pan w ill automatically reset. However, the controller’s condensate overflow diagnostic
must be m anually reset to clear the diagnostic and restart the unit.

Addit ional Functions of the
ZN 5 2 4 Cont roller
When the building owners choice is
Trane Tracer controls, the ZN524 controller is required w hen any of the following applications are selected on a

Waterside Econom izer
Hot Gas Reheat
(for Dehum idification)
Boilerless Control for Electric Heat
Water Isolation Valve Control
(for Variable Speed Pum ping)
Ent ering Wat er Temperature
Sampling
The ZN524 controller will sam ple the
entering water tem perature to determine proper control action for units
equipped with boilerless electric heat
or waterside econom izer.
Waterside Economizer: Entering
water tem perature (EWT) sampling
will automatically occur at pow er up
when the unit is equipped w ith a waterside econom izer (WSE). The EWT is
used to determ ine if economizing is
feasible. When the conditions are met,
the isolation valve(s) are driven open
for three minutes and the EWT reading
is taken. The determ ination as to
whether or not the economizer can be
enabled will be made and the controller will take appropriate action. The
isolation valve will remain open regardless if the WSE or the DX cooling
is enabled.
The unit’s waterside econom izer will
contain a 2-position water valve w ired
to the ZN524. The econom izing water
coil w ill be optim ized to provide 100%
of the unit capacity at 80.6 F/66.2 F return air tem peratur e with 45 F entering
water. The flow rate is established at
86 F entering w ater temperature and
96 F leaving water tem perature.
Low leaving air protection will be furnished to protect the unit against delivering air that is cold enough to
sweat discharge air grilles. Coil icing
protection will also be provided.
Waterside economizer cooling w ill be
active during occupied, unoccupied
and standby cooling m odes.
Boilerless Cont rol Electric Heat
and Supplemental Electric Heat :
The ZN524 supports a single stage of
boilerless electric heat operation or
concurrent heating.
When the unit is configured for boilerless control, the EWT w ill be used to
determ ine w hether DX heating should
be disabled and the electric heater enabled. When these conditions are m et,
the isolation valve(s) are driven open
for three minutes and the entering water tem perature reading is taken. The
determ ination as to w hether or not to
utilize electric heat will be made and
the controller will take appropriate action. If boilerless electric heat is enabled, then the isolation valve will be
closed, shutting down the w ater flow
to the unit.
When the unit is configured for concurrent operation of DX heating (com pressor in heat pump m ode) and
electric heat, the electric heat will act
as a second stage of heat for single
com pressor units, and a third stage of
heat for dual com pressor units. Note:
With concurrent (or supplem ental)
electric heat, the electric heater is field
provided.
Water Isolat ion V alves
Variable speed pumping systems are
supported by the ZN524 controller
when water isolation valves are
present. Up to tw o isolation valves are
supported by the controller (one for
each compressor circuit).
The valves are normally closed unless
DX heating, DX cooling, w aterside
econom izer or dehum idification is requested. When the isolation valves are
driven open for operation, the outputs
will be driven for 20 seconds to ensure
adequate water flow before the compressor outputs are energized. Once
an isolation valve has been opened, it
will remain open for a 10 minute minimum to reduce excessive cycling of
the valve.
Dehum idificat ion
Dehumidification for the single and
du al circuited water-source heat pum p
is applicable w ith the ZN524 controller. The controller is capable of directing one stage of DX cooling in
conjunction w ith one stage of reheat
(hot gas reheat).
Dehumidification can only occur w hen
the controller is in the cooling m ode. A
humidity transmitter is used to m easure the zone’s relative hum idity (RH),
then compares the zone relative humidity to the relative humidity enable/
disable setpoint parameters. The default values for dehum idification enable is 60% RH with the disable point
at 52% RH. These values are configurable.

How it Work s?
Cooling M ode (Figure 3 4 ) If cooling is called for, the therm ostat activates the
centrifugal blow er and sets the reversing valve into the co ol in g p osi ti on . If al l
safeties are met, high temperature refrigerant vapor is pumped from the
com pressor throught the reversing valve to the
refrigerant-to-water heat exchanger. The refrigerant
vapor condenses to a liquid as it passes through the heat
exchanger, giving up its heat to the circulating w ater
loop. High pressure liquid refrigerant then passes
through the expansion device into the
refrigerant-to-air fin
tube coil heat
exchanger. As the low
pressure refrigerant
passes through the coil,
it evaporates to becom e
a low tem perature
vapor, absorbing heat
from the air, w hich is
drawn over the coil by the blower. The refrigerant
then flows as a low pressure gas through the rever sing valve back to the suction side of the compressor where
the cycle begins again.
Heat ing M ode (Figure 3 5 ) If heating is called for, the therm ostat activates the
cent rif ugal blow er and sets the reversing valve into t he h eati ng po sit ion. If
all safeties are met, high temperature refrigerant vapor is
pumped from the compressor through the reversing
valve to the ref rigerant-to-air fin tube coil heat
exchanger. The high pressure refrigerant vapor
condenses to a liquid as it passes through the coil,
giving up its heat to the air which is drawn over the
coil by the b low er. Liquid refrigerant th en
passes through the
expansion devise into
the
refrigerant -t o-w ater
heat exchanger. As the
low pressure
refrigerant passes
through the heat
exchanger, it evaporates
to become a low tem perature vapor,
absorbing heat from the circulating water. The
refrigerant then flows as a low pressure gas through the
reversing valve back to the suction si de o f t he
compressor w here the cycle begins again.

Considerations
Flexibility
The high efficiency vertical and horizontal w ater-source heat pump system is versatile for installation in
boiler/cooling tow er applications, as
well as ground-source (geothermal)
applications. The system design m ay
employ either a central pumping design, or a distributed pumping design.
A central pum ping design involves a
single pump design, usually located
within a basement or mechanical
room to fulfill pumping requirem ents
for the entire building system . An auxiliary pum p is typically applied to lessen the likelihood of system dow ntime
if the main pump m alfunctions.
A distributed pumping system contai ns a single pump m odule connected
directly to the units supply and return.
This module is field installed and
piped to the unit. This design requires
individual pum p modules specifically
sized for each w ater-source heat
pump.
Advantages of Geot hermal
The advantages of a geotherm al heat
pump system could literally cut a business’ heating and cooling costs by 30
to 40-percent. The units are durable,
and typically last longer than conventional system s because they are protected from harsh outdoor weather
conditions, and 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 pum ps have few er
mechanical com ponents, making
them more reliable and less prone to
failure. M anufacturers of the loop materials guarantee their products for up
to 25-years, with no m aintenance required.
Geothermal heat pum ps work toward
the preservation of the
environment by reducing the environmental impacts of electric power generation.
A ground source (geotherm al)
system consist of a:
• A ground w ater heat pum p
• A closed loop ground heat exchanger made of high density
polyethylene pipe (guaranteed
25- years or more by many manufacturers); and
• A low wattage circulating pump(s)
The fluctuating tem peratures of fluid
from the earth are m ore stable than
air, allow ing the equipment to operate
at a low er discharge pressure and use
few er kilow atts. The constant earth
tem perature will heat or cool the fluid
running through buried high density
polyethylene pipe to provide heating
and cooling to a building.
Figure 36: Geo thermal energy r ecovery loop
A geothermal loop can be installed either horizontally or vertically. Vertical
loops require less overall land area to
reject (i.e., sink) the excess heat from
the building. Horizontal loops require
trenches in the ground spanning a
larger overall land area.
Although external piping is the responsibility of the installer and/or piping m anufacturer, many electric
utilities and rural electric cooperatives
are offering monetary incentives to install geothermal system s. Utility com panies offer the incentives because of
reduced peak loads that flatten out
their dem and curve over tim e, and
save them m oney. These savings are
ultimately transferred to the consum er. See Figure 3 6 for geotherm al energy recovery loop.

Considerations
Boiler/Cooling Tow er Application
In a boiler/cooling tow er application (Figure 3 7 ), th e clo sed w at er-l oo p, along
with m ultiple w ater-source heat pumps are utilized in a m ore conventional
manner.
Typically, a boiler is used to maintain closed-loop tem peratures
above 60 F, and a cooling tower is used to maintain
closed-loop temperature below 90 F. All the units
function independently, either by adding heat,
or rejecting heat, or moving heat from the
closed w ater-loop. Because the heat
from a building is being rejected
through a cooling tow er, the system
is m ore efficient than air cooled system s.
The boiler/cooling tower system provides a low installation cost to the
ow ner w hen compared to other system s, and is the most com m on application. It also allows the ow ner t o add units to
the condenser w ater loop as needed.
Ground Coupled A pplicat ion
Systems that utilize the ground-coupled (geother m al) d esig n ar e also app li ed to
a closed w ater-loop, along w ith the multiple ground-source heat pum ps.
With the ground-coupled (geothermal) system , heat is exchanged w ith the earth
by either moving heat into the earth, or absorbing heat from the earth. Water
tem perature ranges vary from 25 F to 105 F depending on climate, and season.
Because the ground-coupled system does not use the fluctuating outsi de-ai r
tem perature, the geotherm al heat pumps are capable of using less energy.
The choices in earth-loop coupling consists of a vertical (Figure 3 8 ), horizontal, or a pond-loop design. Each of these options offer different
system design characteristics. The vertical and horizontal loop
systems can be designed to provide the sam e fluid tem peratures under a given set of conditions.
Operating and maintenance cost are lower
because an auxiliary electric/fossil fuel
boiler and cooling tow er are not required to m aintain the loop tem perature in a properly designed system .
Because the ground loop is made of
chem ical ly i nert , non -pol lut ing , hig h
density polyethylene pipe, the loop
is environm entally responsible. The
heat pumps use HCFC-22 refrigerant,
which has a low ozone depletion potential. Because the closed-loop system does

Open-Loop Design
Ground w ater from a well can be used to exchange heat
in an open-loop system Figure 39. The ground
water is pum ped from the well into the geotherm al
heat pump, w here heat is extracted or rejected and
then returned to an aquifer. The only change to the
ground water is a slight tem perature difference. The
rejected water is dum ped into a surface well,
lake, or stream , continually rem oving
water from the aquifer. Alternatively,
a recharge well may be installed to
return the w ater into the ground.
Open-loop systems use a large
amount of water, and can only
be economically justified w here
wells and disposal system s are
easy to install.
Operation and benefits are
sim ilar to those for closed-loop
systems. There are, how ever, several
considerations that should be addressed
prior to installation.
1 Water quality m ust be acceptable, with m inimal suspended solids
and proper pH. To help ensure clean w ater, a straining device m ay be
required.
2 An acceptable way to discharge the significant vol um e o f u sed w at er f ro m
the heat pump should be defined. It m ay be necessary to install a recharge
well to return the w ater to the aquifer.
Slinky Loop
With the slink y-loop system application Figure 40,
groups of w ater-coupling, pipe coils are subm erged
several feet below the low water level or w ithin a
horizontal ground trench. This system has all of the
advantages of a vertical bore, or horizontal trench
application, and can be very cost effective
when applied in the proper land region.
With the slinky-loop system design,
som e special considerations should be
taken for the installation if a pond
application is used.
1 The body of w ater should be close
to the structure. If the distance
from the w ater to the building m ust
accom m odate a horizontal field, the
submerged loop w ould offer no
advantage over a horizontal w ater-loop

Cent ral Pum ping System
Units that em ploy a central pum ping
system contain single or dual pumps
to fulfill pum ping requirements for the
entire building system.
The central system ’s supply and return lines should be sized to handle
the required flow w ith a minim um
pressure drop.
The w ater-source heat pump (in this
case a high efficiency GEH) may in clude add-on accessories to help aid in
system balancing, acoustics and safety requirem ents. Some of these items
may be ordered from the factory, then
field installed. Many are provided by
the contractor.

A two position isolation valve is
often applied to system s w hich incorporate variable frequency
pumping. This valve is capable of

Hanging the Horizontal
The horizontal unit GEH is a ceiling hung unit. It is
usually applied as a totally concealed unit above an
acoustical ceiling grid.
Because the GEH is equipped w ith several inlet and
discharge arrangem ents, it allows for num erous
application needs, and is field convertible at the jobsite.
The GEH and GEV units are equipped with a dual
sloped, non corrosive drain pan to enhance drainability
and indoor air quality.
When hanging the horizontal GEH design, local building
codes may require the unit to be pitched approximately
1/4-inch per foot tow ard the drain in both directions.
This aids in condensate removal from the drain pan. See
Figure 41 for unit slope.

filter racks, filter and grommets are field installed. These
items are shipped in an inclosure external to the unit.

Condensat e Traps
When designing a condensate trap for the w ater-source system, it’s important to
consider the unit’s draw through design.
Under norm al conditions, condensate runs down the coil fins and drips into a
condensate pan. In situations w here no trap is installed, the w ater level that
would be m aintained in the trap to create a seal, backflow s through the drainline
into the unit. Because the fan pulls air through the air-to-refrigerant
heat-exchanger, this incom ing air stream could launch water droplets, form ing
at the base of the coil, into the air. Air flow ing through the coil can th en sp ray
condensate into the fan intake, with the possibility of propelling m oi stu re i nt o
other parts of the m echanical system . This aerosol m ist can be carried through
the ducts and into the conditioned air space.
Another problem w ith air backflow, is the source of that air. Drain lines typically
flow into w aste or sewage lines, giving the potential to introduce methane and
other contam inants from the drain system into the airstream.
In a properly trapped system , w hen
condensate forms during norm al
operation, the w ater level in the trap rises
until there is a constant outflow. See
Figure 43, for the appropriate
dimensions required in designing a
negative pressure system .

Installation M ade Easy
Installing a horizontal unit inside a corridor to enhance sound attenuation pro vi des v alu e to du ct design. Trane takes this
fact one step further.
The new GEH design offers sam e side return-air/supply-air access to the unit. This access is contained wi th in th e ov eral l
dimension of the units length as show n in Figure 44. The duct access t o t he u ni t al lo w s the unit to be installed closely
against a corridor w all, w hile at the sam e tim e elim inating space required for the duct desig n.
Most horizontal unit designs provide an opposite supply air from the return air arrangem ent, or an end supply arrangem ent
option. See Figure 45 for end-supply example. An end-supply design in creases t he o ver all un it len gt h of the system to
accom m odate a 90-degree duct turn. This not only requires added space, but also adds cost in bo th m ater ial s and installation.
Additional value to the design is acquired through the sam e side suppl y/r etu rn -air desi gn . Thi s desi gn eli minates a requirement for a four sided service access. When installing the same side return/supply-air access, a brief 3-inch m in im u m is al l
that is required between the unit and the w all.

When the unit is OFF, or is in the heating m ode, the valve closes. This is because the pressure acting on the valve

In the heating mode, the valve controlling the water flow is ref err ed to a a

Using Water Regulating Valves
The function of the water regulating
valve assem bly is to m inimize the
amount of water which flows through
the water-source heat pum p. These
valves are most often used in systems
where the water is w asted, but may
also be used in boiler/cooling tower involving v ari able speed pumping. In a
variable speed application, the valves
are used to m eter d esir abl e water flow
through the unit w hen the unit is running, and to stop w ater flow when the
unit is not running (but may not in-clude a 100% shut-off).
The w ater regulating valve assembly
consists of tw o valves piped in parallel. When the w ater-source heat
pump’s com pressor is de-energized,
both valves are closed, allowing no
water to flow through the unit. But,
when the unit com pressor is energized, one of the valves is closed and
the other valve w ill allow w ater flow
through the unit.
In cooling m ode, the valve controlling the water flow is referred to as a
direct acting valve. As the spring tension increases, the head pressure will
also increase. This is due to the decrease in w ater flow through the unit.
Note, the valve is being controlled by
the head pressure. As the head pressure increases, the w ater flow increases, and vice versa. The valve is
controlled by tw o pressures. The refrigerant pressure in the high side of
the system, and the spring pressure,
acting on the opposite side of the
valve.
Note:The spring tensio n o n t he d ir ect

will increase. This is due to the increase in w ater flow through the unit.
Note, the valve is being controlled by
the suction pressure. As the suction
pressure decreases, the water flow increases, and vice versa. The valve is
controlled by tw o pressures. The refrigerant pressure in the low side of
the system, and the spring pressure,
acting on the opposite side of the
valve.
Note: The spring tension on the reverse acting valve m ay be adjusted to
maintain a desired suction pressure.
When the unit is OFF, or is in the cooling m ode, the valve closes. This is because the pressure acting on the valve
is out of the spring set-range.
Both the direct acting and the reverse
acting valves should be tapped into
the same refrigerant line via a schraeder connection. This line m ust be a high
pressure line w hen the unit is in the
cooling mode, and a low pressure line
when the unit is in the heating mode.
The only line that w ill accom m odate
this condition is the vapor line running
between the reversing valve and the
water-to-refrigerant heat exchanger.
Note: In many applications, a water
regulating valve m ay be u sed to m eter
water flow to the eq uipment instead of
metering refrigerant flow to the equipment. This is typically applied w hen
the equipment does not contain a thermal expansion refrigerant m etering
device. Trane places a thermal expansion valve on all water-source and
ground-source heat pum ps to provide
maximum performance of the equipment. Capillary tube assemblies are
not used on Trane w ater-source or
ground-source heat pum p equipment.
Therefore, a w ater regulating valve is
not required on m ost equipm ent applications.

Figure 50: Hybrid system design
Types of A pplicat ions
In system s that use a boiler/cooling
tower design, w ater pum ps are placed
between the auxiliary equipment
(boiler, cooling tow er, etc.) and the
WSHPs to ensure positive w ater
pressure throughout the system.
Through this placem ent, the pum p is
able to pressurize the piping that
serves the units, allow ing the
regulated makeup water to pressurize
the pump section.
With this application, the cooling
tower is used to dissipate heat from
the condensing process. The
condensing w ater is cooled for
recirculation back to the
water-to-refrigerant heat exchanger
by using a com bination of heat and
mass transfer by evaporation. The
type of cooling tow er chosen for the
application may include an
open-circuit cooling tower w ith a
gasket-plate heat exchanger to close
the loop, or a closed-circuit fluid
cooler design.
Hybrid Syst ems
Som e system s have evolved into a hybrid (com bination) system due to
building additions/phases or new requirements.
A hybrid system may have began w ith
a geotherm al ground loop heat exchanger used to extract or add heat to
the building. As additional rooms or
buildings were added onto the system , the ground loop design became
undersized for the new demand. A
cooling tower m ay be the solution to
off-load the peak demand of the new
building addition. This m ay be an inexpensive means of tempering the loop
to it’s appropriate w orking conditions.
The cooling tow er may be used in conjunction w ith the loop to lower loop
tem peratures during off-peak hours
(at night) to support the peak load of
the loop during the day.
Other additions may include a requirement for fresh-air ventilation. A
fresh-air, air handler, along with a
chi ller may be introduced to the closed
loop system to allow tempered
fresh-air into the building.
The buildings heating and cooling
needs are not based off of one type of
com ponent, but perform harmonious
of each other. Because the loop is
closed, heat recovery from the loop itself can be shared with the other m ajor
com ponents.
The heat pum ps are capable of heating or cooling a space independent
of one another to provide individ-
ual heating and cooling needs.
A hybrid system should be con-
sidered on existing building design
when an offset of cooling energy is a
req uir emen t. See Figure 50 for hyb rid
system design.

Procedure
Information in relation to the new
ARI-ISO 13256-1 may be found on
Page 41 of th is catalog. A com plete
calculation of the conversion is
provided.
The performance standard ARI/ISO
13256-1 becam e effective Jan. 1, 2000.
It replaces ARI standards 320, 325 and
330. This new standard has three major categories: Water Loop (ARI 320),
Ground Water (ARI 325), Ground Loop
(ARI 330). Although these standards
are similar there are some differences.
The cooling efficiency is measured in
EER but includes a Watt-per-Watt unit
of measure sim ilar to the traditional
COP measurement.
The entering w ater temperature has
changed to reflect the centigrade tem perature scale. For instance the w ater
loop heating test is perform ed with
68-degree F (20-degree C) water instead of 70-degree F. The cooling tests
are performed w ith 80.6-degree F
(27-degree C) dry bulb and 66.2-degree F (19-degree C) wet bulb entering
air instead of the traditional 80-degree
F dry bulb, and 67-degree F wet bulb
entering air tem peratures. This data
(80.6/66.2) may be converted to 80/67
by using the entering air correction table.
A pum p power correction has been
added onto the existing pow er consum ption. Within each m odel, only
one water flow rate is specified for
each performance category, and
pumping watts are calculated utilizing
the pump pow er correction formula:
(gpm x 0.0631) x press drop x 2990) /
300.
Note: gpm relates to water flow , and
press drop relates to the drop through
the unit heat exchanger at rated w ater
flow in feet of head.
The fan pow er is corrected to zero external static pressure. The nominal airflow is rated at a specific external
static pressure. This effectively reduces the power consumption of the unit,
and increases cooling capacity but de-
creases heating capacity. These w atts
are significant enough in most cases
to increase EER and COP over ARI 320,
325, and 330 ratings.
Cooling Dom inated
Applications
If hum idity levels are m oderate to high
in a cooling dominated application,
the heat pump should be selected to
meet or exceed the calculated sensible
load. Also, the unit’s sensible capacity
should be no more than 115% of the
total cooling load (sensible + latent),
unless the calculated latent load is less
than the latent capacity of the unit.
The sensible-to-total cooling ratio can
be adjusted with airflow. If the airflow
is low ered, the unit latent capacity w ill
increase. When less air is pulled
across the DX coil, more moisture w ill
condense from the air.
Heat ing D ominat ed
Applications
Unit sizing in heating dominated applications is based upon hum idity levels
fo r the climate, and goals for operating
cost and installation costs.
If hum idity levels are moderate, the
heat pump should be selected with the
heating capacity equal to 125% of the
cooling load.
If hum idity levels are low in the application and low operating cost is im portant, the heat pump and ground
loop should be sized for 90% to 100%
of the heating load.
If hum idity levels are low and lower
initial cost is important, then the heat
pump and ground loop should be
sized for 70% to 85% of the heating
load, w ith the rem aining load to be
treated with electric resistance heat.
Installation cost will be reduced in this
approach because of the sm aller heat
pump selection and less loop m aterials.
In general, the system w ill not use
enough electric heat to offset the higher installation costs associated with a
fully sized or oversized system.
Finally, a unit sized for the entire heating load in a heating dom inated application will be oversized in cooling.
Comfort is reduced from increased
room hum idity caused by short-run
times. Short cycling w ill also shorten
the life expectancy of the equipment
and increase pow er consum ption and
operating cost.
Many rebate incentives require the
heat pump and ground loop to be
sized for the entire heating load. Check
with you local utility for their requirements.
