Form 50PSW-C1PD
Features/Benefits (cont)
These units offer industry leading
energy efficiency and environmental
benefits by utilizing Carrier’s Puron®
refrigerant (R-410A) that eliminates all
concerns of mandated refrigerant
phase-out of R-22 (HCFC) in 2010.
Each unit has been specifically
designed for Puron refrigerant to provide years of optimum efficiencies with
long life.
Puron® refrigerant (R-410A)
Puron refrigerant (R-410A) is a nonchlorine based refrigerant. Puron refrigerant characteristics, compared to
R-22, are:
• Binary and near azeotropic mixture
of 50% R-32 and 50% R-125.
• Higher efficiencies (50 to 60%
higher operating pressures).
• Non-ozone depleting potential and
low global warming potential.
• Virtually no glide. Unlike other
alternative refrigerants, the two
components in Puron refrigerant
have virtually the same leak rates.
Therefore, refrigerant can be added
if necessary without recovering the
charge.
High quality construction and
testing
All units are manufactured to meet
extensive quality control protocol from
start to finish through an automated
control system, which provides continuous monitoring of each unit and
performs quality control checks as
equipment progresses through the production process. Standard construction features of the Aquazone™ units
include:
Cabinet — Standard cabinet construction consists of heavy gage galvanized
sheet metal that provides maximum
strength. Cabinet interior surfaces are
lined with 13 mm thick, 28 kg/m3
acoustic type insulation. All exterior
sheet metal surfaces are powderpainted to increase corrosion protection and resilience for long term vitality. Cabinets are designed with service
access panels on the front for easy
accessibility.
Compressors — Standard highefficiency scroll compressors are
mounted on rubber grommets to large,
heavy gage mounting tray plates,
which are then isolated from the
cabinet base with rubber grommets.
This dual level vibration isolation
2
system dramatically increases vibration
attenuation.
Refrigeration/water circuit —
Units have two sealed refrigerant circuits including scroll compressors.
Refrigerant circuits are provided with
standard thermostatic expansion valves
(TXVs) for higher accuracy and performance. Also standard are a reversing
valve (4-way valve) and load and source
water-to-refrigerant coaxial (tube in
tube) coils.
Quality assurance — Aquazone
units have NRTL (Nationally Recognized Testing Lab) or ETL labels and
are factory tested under normal operating conditions at nominal water flow
rates. Quality assurance is provided via
testing report cards shipped with each
unit to indicate specific unit performance under cooling and heating
modes of operation.
Quiet operation
Rubber grommets are provided for
sound isolation and cabinets are fully
insulated to reduce noise transmission.
Design flexibility
Units have an entering source water
temperature range from –5 to 45 C
(40 C for sizes 180 and 360) and entering (heating) load water temperature
range from 15 to 50 C or entering
(cooling) load water temperature range
of 10 to 30 C as standard.
Safe, reliable operation
Standard safety features for the refrigerant circuit include a high-pressure
switch and low-pressure sensor to
detect loss of refrigerant. Equipment
safety features include water loop
temperature monitoring, voltage
protection, and source freeze protection. All safety features are tested and
run at the factory to assure proper
operation of all components and safety
switches.
All components are carefully
designed and selected for endurance,
durability, and carefree, day-to-day
operation.
The unit is shipped to provide internal and external equipment protection.
Shipping supports are placed under
the compressor feet.
Ease of installation
The unit is packaged for simple low
cost handling, with minimal time
required for installation. All units are
pre-wired and factory charged with
refrigerant. Water connections (FPT),
high and low voltage knockouts, and
an easily accessible design reduce
installation time and save mechanical
room space.
Simple maintenance and
serviceability
For better flexibility in confined spaces,
access for maintenance and service is
provided from three sides of the unit.
Large access panels on the top, side,
and front of the unit maximize exposure for all components. Easy removal
of the control box from the unit provides access to all refrigeration components. The refrigeration circuit is easily
tested and serviced through the use of
high and low pressure ports integral to
the refrigeration circuit. All maintenance and service can be completed
through the front of the unit, allowing

Maximum control flexibility
Aquazone™ water source heat pumps
provide reliable control operation using
a standard microprocessor board with
flexible alternatives for many direct digital control (DDC) applications including the Carrier Comfort Network®
(CCN) and open protocol systems.
Carrier’s Aquazone standard unit
solid-state control system, the Complete C control, provides control of the
unit compressor, reversing valve, fan,
safety features, and troubleshooting
fault indication features. The Complete
C control is one of the most user
friendly, low cost, and advanced
control boards found in the WSHP
industry. Many features are field selectable to provide the ultimate in field
installation flexibility. The overall features of this standard control system
include:
Transformer (75 va) — The transformer assists in accommodating
accessory loads with a load side short
circuit and overload protection via a
built-in circuit breaker.
Anti-short cycle timer — The timer
provides a minimum off time to prevent the unit from short cycling. The
5-minute timer energizes when the
compressor is deenergized, resulting in
a 5-minute delay before the unit can be
restarted.
Random start relay — The relay
ensures a random delay in energizing
each different WSHP unit. This option
minimizes peak electrical demand during start-up from different operating
modes or after building power outages.
High and low pressure refrigerant
protection — Refrigerant protection
safeguards against unreliable unit operation and helps prevent refrigerant
from leaking.
High and low voltage protection
— Voltage safety protection guards
against excessive or low voltage
conditions.
Automatic intelligent reset — The
unit automatically restarts 5 minutes
after shutdown if the fault has cleared.
Should a fault occur 3 times sequentially, then lockout will occur.
Accessory output — A 24-v output
is provided to cycle a motorized water
valve, damper actuator, etc. with compressor for applications such as variable speed and primary secondary
pumping arrangements.
Performance Monitor (PM) — This
unique feature monitors water temperatures and warns when the heat pump
is operating inefficiently or beyond
typical operating range. Field selectable switch initiates a warning code on
the unit display.
Source freeze protection (selectable for water or antifreeze) —
This field-selectable switch for water
and water/glycol solution systems initiates a fault when temperatures exceed
the selected limit for 30 continuous
seconds.
Alarm relay setting — A selectable
24-v or pilot duty dry contact provides
activation of a remote alarm.
Service test mode with diagnostic
LED (light-emitting diode) — The
Test mode allows service personnel to
check the operation of the WSHP and
control system efficiently. Upon entering Test mode, time delays are sped up
and the Status LED will flash a code to
indicate the last fault experienced for
easy diagnosis. Based on the fault code
flashed by the status LED, system diagnostics are assisted through the use of
Carrier-provided troubleshooting tables
for easy reference to typical problems.
LED visual output — An LED panel
indicates high pressure, low pressure,
low voltage, high voltage, air/water
freeze protection, condensate overflow, and control voltage status.

NOTE: The source entering water temperature can
be –7 C to 44 C. The load entering water temperature can be 10 C to 49 C. Also, water flow can be
as low as 2.2 L/s per kW for constant temperature
liquid (e.g., well water) or as high as 4.4 L/s per kW
for variable liquid temperature.
IV Evaluate a unit based on total cooling and
heating conditions. Unit selected should be
closest to the actual loads.
At the conditions identified, the unit heating and
cooling performance is read on the heating and
cooling performance tables for a 50PSW360 unit.
Total Capacity — Heating . . . . . . . . . . . .78.8 kW
Total Capacity — Cooling . . . . . . . . . . . .72.1 kW
NOTE: Interpolation is permissible if the design criteria are not identified in the tables.
V Evaluate the leaving water temperature.
The leaving water temperature should be appropriate for the application (e.g., chilled water or hot
water for tempering ventilation air). If the leaving
load water temperature is above freezing, freeze
protection (e.g., glycol/water solution) is not
required.

NOTES:
1. Selecting multiple units to accomplish a heating
and/or cooling load by piping the load heat
exchanger sides in parallel flow:
If design heating and/or cooling loads for the load heat
exchanger cannot be accomplished with a single
50PSW unit, the same selection procedure can be utilized to add multiple units. The capacities of two units
can be added together when piped in parallel. Refer to
the Application Data section for details on parallel
operation.
2. Selecting multiple units to accomplish a lower
cooling leaving water temperature than can be
accomplished by one 50PSW unit:
If design leaving water temperature from the load heat
exchanger for cooling cannot be accomplished with a
single 50PSW unit, the same selection procedure can
be utilized to add multiple units. The leaving water temperature can be further lowered for multiple units when
piped in series. Refer to the Application Data section
for details on series operation.

NOTES:
1. Interpolation is permissible, extrapolation is not.
2. For operation in the shaded area when water is used in lieu of an antifreeze solution, the
LWT (leaving water temperature) must be calculated. Flow must be maintained to a level so
that the LWT is maintained above 6 C when the JW3 jumper is not clipped. Because the
refrigerant temperature can potentially reach as low as 0° C with 4 C LWT, a nuisance cutout could occur due to the activation of the low temperature protection. The JW3 jumper
should never be clipped for standard range equipment or systems without antifreeze.
3. All entering air conditions are 27 C DB and 19 C WB in cooling and 20 C DB in heating.
4. Table does not reflect fan or pump power corrections for AHRI/ISO conditions.
5. All performance data is based upon the lower voltage of dual voltage rated units.
6. Performance stated is at the rated power supply; performance may vary as the power supply varies from the rated.
7. Operation below 4 C EWT is based upon a 15% methanol antifreeze solution.
8. Operation below 16 C EWT requires optional insulated water/refrigerant circuit.
9. See performance correction tables for operating conditions other than those listed above.

NOTES:
1. Interpolation is permissible, extrapolation is not.
2. For operation in the shaded area when water is used in lieu of an antifreeze solution, the
LWT (leaving water temperature) must be calculated. Flow must be maintained to a level so
that the LWT is maintained above 6 C when the JW3 jumper is not clipped. Because the
refrigerant temperature can potentially reach as low as 0° C with 4 C LWT, a nuisance cutout could occur due to the activation of the low temperature protection. The JW3 jumper
should never be clipped for standard range equipment or systems without antifreeze.
3. All entering air conditions are 27 C DB and 19 C WB in cooling and 20 C DB in heating.
4. Table does not reflect fan or pump power corrections for AHRI/ISO conditions.
5. All performance data is based upon the lower voltage of dual voltage rated units.
6. Performance stated is at the rated power supply; performance may vary as the power supply varies from the rated.
7. Operation below 4 C EWT is based upon a 15% methanol antifreeze solution.
8. Operation below 16 C EWT requires optional insulated water/refrigerant circuit.
9. See performance correction tables for operating conditions other than those listed above.

NOTES:
1. Interpolation is permissible, extrapolation is not.
2. For operation in the shaded area when water is used in lieu of an antifreeze solution, the
LWT (leaving water temperature) must be calculated. Flow must be maintained to a level so
that the LWT is maintained above 6 C when the JW3 jumper is not clipped. Because the
refrigerant temperature can potentially reach as low as 0° C with 4 C LWT, a nuisance cutout could occur due to the activation of the low temperature protection. The JW3 jumper
should never be clipped for standard range equipment or systems without antifreeze.
3. All entering air conditions are 27 C DB and 19 C WB in cooling and 20 C DB in heating.
4. Table does not reflect fan or pump power corrections for AHRI/ISO conditions.
5. All performance data is based upon the lower voltage of dual voltage rated units.
6. Performance stated is at the rated power supply; performance may vary as the power supply varies from the rated.
7. Operation below 4 C EWT is based upon a 15% methanol antifreeze solution.
8. Operation below 16 C EWT requires optional insulated water/refrigerant circuit.
9. See performance correction tables for operating conditions other than those listed above.

NOTES:
1. Interpolation is permissible, extrapolation is not.
2. For operation in the shaded area when water is used in lieu of an antifreeze solution, the
LWT (leaving water temperature) must be calculated. Flow must be maintained to a level so
that the LWT is maintained above 6 C when the JW3 jumper is not clipped. Because the
refrigerant temperature can potentially reach as low as 0° C with 4 C LWT, a nuisance cutout could occur due to the activation of the low temperature protection. The JW3 jumper
should never be clipped for standard range equipment or systems without antifreeze.
3. All entering air conditions are 27 C DB and 19 C WB in cooling and 20 C DB in heating.
4. Table does not reflect fan or pump power corrections for AHRI/ISO conditions.
5. All performance data is based upon the lower voltage of dual voltage rated units.
6. Performance stated is at the rated power supply; performance may vary as the power supply varies from the rated.
7. Operation below 4 C EWT is based upon a 15% methanol antifreeze solution.
8. Operation below 16 C EWT requires optional insulated water/refrigerant circuit.
9. See performance correction tables for operating conditions other than those listed above.

NOTES:
1. Interpolation is permissible, extrapolation is not.
2. For operation in the shaded area when water is used in lieu of an antifreeze solution, the
LWT (leaving water temperature) must be calculated. Flow must be maintained to a level so
that the LWT is maintained above 6 C when the JW3 jumper is not clipped. Because the
refrigerant temperature can potentially reach as low as 0° C with 4 C LWT, a nuisance cutout could occur due to the activation of the low temperature protection. The JW3 jumper
should never be clipped for standard range equipment or systems without antifreeze.
3. All entering air conditions are 27 C DB and 19 C WB in cooling and 20 C DB in heating.
4. Table does not reflect fan or pump power corrections for AHRI/ISO conditions.
5. All performance data is based upon the lower voltage of dual voltage rated units.
6. Performance stated is at the rated power supply; performance may vary as the power supply varies from the rated.
7. Operation below 4 C EWT is based upon a 15% methanol antifreeze solution.
8. Operation below 16 C EWT requires optional insulated water/refrigerant circuit.
9. See performance correction tables for operating conditions other than those listed above.

NOTES:
1. Interpolation is permissible, extrapolation is not.
2. For operation in the shaded area when water is used in lieu of an antifreeze solution, the
LWT (leaving water temperature) must be calculated. Flow must be maintained to a level so
that the LWT is maintained above 6 C when the JW3 jumper is not clipped. Because the
refrigerant temperature can potentially reach as low as 0° C with 4 C LWT, a nuisance cutout could occur due to the activation of the low temperature protection. The JW3 jumper
should never be clipped for standard range equipment or systems without antifreeze.
3. All entering air conditions are 27 C DB and 19 C WB in cooling and 20 C DB in heating.
4. Table does not reflect fan or pump power corrections for AHRI/ISO conditions.
5. All performance data is based upon the lower voltage of dual voltage rated units.
6. Performance stated is at the rated power supply; performance may vary as the power supply varies from the rated.
7. Operation below 4 C EWT is based upon a 15% methanol antifreeze solution.
8. Operation below 16 C EWT requires optional insulated water/refrigerant circuit.
9. See performance correction tables for operating conditions other than those listed above.

NOTES:
1. Interpolation is permissible, extrapolation is not.
2. For operation in the shaded area when water is used in lieu of an antifreeze solution, the
LWT (leaving water temperature) must be calculated. Flow must be maintained to a level so
that the LWT is maintained above 6 C when the JW3 jumper is not clipped. Because the
refrigerant temperature can potentially reach as low as 0° C with 4 C LWT, a nuisance cutout could occur due to the activation of the low temperature protection. The JW3 jumper
should never be clipped for standard range equipment or systems without antifreeze.
3. All entering air conditions are 27 C DB and 19 C WB in cooling and 20 C DB in heating.
4. Table does not reflect fan or pump power corrections for AHRI/ISO conditions.
5. All performance data is based upon the lower voltage of dual voltage rated units.
6. Performance stated is at the rated power supply; performance may vary as the power supply varies from the rated.
7. Operation below 4 C EWT is based upon a 15% methanol antifreeze solution.
8. Operation below 16 C EWT requires optional insulated water/refrigerant circuit.
9. See performance correction tables for operating conditions other than those listed above.

NOTES:
1. Interpolation is permissible, extrapolation is not.
2. For operation in the shaded area when water is used in lieu of an antifreeze solution, the
LWT (leaving water temperature) must be calculated. Flow must be maintained to a level so
that the LWT is maintained above 6 C when the JW3 jumper is not clipped. Because the
refrigerant temperature can potentially reach as low as 0° C with 4 C LWT, a nuisance cutout could occur due to the activation of the low temperature protection. The JW3 jumper
should never be clipped for standard range equipment or systems without antifreeze.
3. All entering air conditions are 27 C DB and 19 C WB in cooling and 20 C DB in heating.
4. Table does not reflect fan or pump power corrections for AHRI/ISO conditions.
5. All performance data is based upon the lower voltage of dual voltage rated units.
6. Performance stated is at the rated power supply; performance may vary as the power supply varies from the rated.
7. Operation below 4 C EWT is based upon a 15% methanol antifreeze solution.
8. Operation below 16 C EWT requires optional insulated water/refrigerant circuit.
9. See performance correction tables for operating conditions other than those listed above.

NOTES:
1. Interpolation is permissible, extrapolation is not.
2. For operation in the shaded area when water is used in lieu of an antifreeze solution, the
LWT (leaving water temperature) must be calculated. Flow must be maintained to a level so
that the LWT is maintained above 6 C when the JW3 jumper is not clipped. Because the
refrigerant temperature can potentially reach as low as 0° C with 4 C LWT, a nuisance cutout could occur due to the activation of the low temperature protection. The JW3 jumper
should never be clipped for standard range equipment or systems without antifreeze.
3. All entering air conditions are 27 C DB and 19 C WB in cooling and 20 C DB in heating.
4. Table does not reflect fan or pump power corrections for AHRI/ISO conditions.
5. All performance data is based upon the lower voltage of dual voltage rated units.
6. Performance stated is at the rated power supply; performance may vary as the power supply varies from the rated.
7. Operation below 4 C EWT is based upon a 15% methanol antifreeze solution.
8. Operation below 16 C EWT requires optional insulated water/refrigerant circuit.
9. See performance correction tables for operating conditions other than those listed above.

NOTES:
1. Interpolation is permissible, extrapolation is not.
2. For operation in the shaded area when water is used in lieu of an antifreeze solution, the
LWT (leaving water temperature) must be calculated. Flow must be maintained to a level so
that the LWT is maintained above 6 C when the JW3 jumper is not clipped. Because the
refrigerant temperature can potentially reach as low as 0° C with 4 C LWT, a nuisance cutout could occur due to the activation of the low temperature protection. The JW3 jumper
should never be clipped for standard range equipment or systems without antifreeze.
3. All entering air conditions are 27 C DB and 19 C WB in cooling and 20 C DB in heating.
4. Table does not reflect fan or pump power corrections for AHRI/ISO conditions.
5. All performance data is based upon the lower voltage of dual voltage rated units.
6. Performance stated is at the rated power supply; performance may vary as the power supply varies from the rated.
7. Operation below 4 C EWT is based upon a 15% methanol antifreeze solution.
8. Operation below 16 C EWT requires optional insulated water/refrigerant circuit.
9. See performance correction tables for operating conditions other than those listed above.

NOTES:
1. Interpolation is permissible, extrapolation is not.
2. For operation in the shaded area when water is used in lieu of an antifreeze solution, the
LWT (leaving water temperature) must be calculated. Flow must be maintained to a level so
that the LWT is maintained above 6 C when the JW3 jumper is not clipped. Because the
refrigerant temperature can potentially reach as low as 0° C with 4 C LWT, a nuisance cutout could occur due to the activation of the low temperature protection. The JW3 jumper
should never be clipped for standard range equipment or systems without antifreeze.
3. All entering air conditions are 27 C DB and 19 C WB in cooling and 20 C DB in heating.
4. Table does not reflect fan or pump power corrections for AHRI/ISO conditions.
5. All performance data is based upon the lower voltage of dual voltage rated units.
6. Performance stated is at the rated power supply; performance may vary as the power supply varies from the rated.
7. Operation below 4 C EWT is based upon a 15% methanol antifreeze solution.
8. Operation below 16 C EWT requires optional insulated water/refrigerant circuit.
9. See performance correction tables for operating conditions other than those listed above.

NOTES:
1. Interpolation is permissible, extrapolation is not.
2. For operation in the shaded area when water is used in lieu of an antifreeze solution, the
LWT (leaving water temperature) must be calculated. Flow must be maintained to a level so
that the LWT is maintained above 6 C when the JW3 jumper is not clipped. Because the
refrigerant temperature can potentially reach as low as 0° C with 4 C LWT, a nuisance cutout could occur due to the activation of the low temperature protection. The JW3 jumper
should never be clipped for standard range equipment or systems without antifreeze.
3. All entering air conditions are 27 C DB and 19 C WB in cooling and 20 C DB in heating.
4. Table does not reflect fan or pump power corrections for AHRI/ISO conditions.
5. All performance data is based upon the lower voltage of dual voltage rated units.
6. Performance stated is at the rated power supply; performance may vary as the power supply varies from the rated.
7. Operation below 4 C EWT is based upon a 15% methanol antifreeze solution.
8. Operation below 16 C EWT requires optional insulated water/refrigerant circuit.
9. See performance correction tables for operating conditions other than those listed above.

Water loop system
Water loop (or boiler/tower) system applications typically
include a number of units plumbed to a common piping
system. For optimal performance, this system should be
designed between 2.9 and 3.9 L/s per kW of cooling
capacity. The system is comprised of highly efficient packaged reverse cycle heat pump units interconnected by a
water loop. The water circuit serves as both a sink and
source for heat absorption and rejection and is designed
for entering water temperatures between 15 C and 35 C.
Within this temperature range, units can heat or cool as
required from the same water source. Transferring heat
from warm to cold spaces in the building conserves energy
rather than creating new heat.
Refer to the Carrier Water Source Heat Pump System
Design Guide for assistance with the design of water loop
systems. The guide includes a practical approach for the
latest and most current design recommendations including:
• Product application including horizontal, vertical, console, rooftop, and water-to-water applications.
• Ventilation methods and system design including energy
recovery.
• Acoustical considerations for different product types.
• Addressing IAQ (indoor air quality) issues such as condensate removal and humidity control.
• Air distribution design including diffuser selection/layout
and ductwork design.
• Hydronic system design including pipe sizing/layout
and boiler/tower sizing.
• Control configurations such as stand-alone, DDC, DCV,
and VVT® (variable volume and temperature).
• WSHP Efficiency/Operational Cost Comparison charts.
• System applications such as a system without a boiler,
variable pumping, and VAV (variable air volume) for
interior use.
Ground water systems
To utilize Aquazone units in ground water applications,
extended range should be specified. This will provide
factory-installed insulation on the coaxial coil to prevent
condensate from dripping when entering-water temperatures are below 15 C. The standard copper coaxial coil on
the Aquazone units may not be suitable for certain water
conditions. Refer to the Water Conditioning section for
proper coaxial coil material selection.
Surface water system — This system is typically located
near a lake or pond. In this application, the loop can be
submerged in a series of coils beneath the water surface.
The number of coils required depends on system load and
design. This application requires minimum piping and
excavation.
Open loop system — This system is used where ground
water is plentiful. In this application, ground water is
pumped through supply piping from the well to the building.
The water is then pumped back into the ground through a
discharge well as it leaves the building. An additional heat
exchanger is usually installed between the building water
piping system and the ground water piping system. This design limits the amount of piping and excavation required.
Aquazone units are provided with a standard TXV and
are rated to extremely low temperatures to self-adjust the
refrigeration circuit, therefore water regulating valves are
not required on open loop systems. To conserve water on
this type of system, a slow opening/closing solenoid valve
is recommended.
Ground loop systems
There are many commonly specified designs for ground
loop applications. Typical designs include vertical loops
and horizontal loops. In some applications, water is piped
from the ground or lake directly to the water source heat
pump. Piping is limited to the amount of pipe required to
get the water from the source to the unit.
NOTE: When utilizing Aquazone water source heat pumps
in ground loop systems, refer to design considerations in
the ground water system section.
Horizontal ground loop — This system is used when
adequate space is available and trenching can be easily accomplished. A series of parallel pipes are laid out in trenches 1 to 2 m below the ground surface and then back-filled.
Multiple pipes are often used to maximize the heat transfer
capability of each trench. The amount of pipe and the size
of the ground loop field are based on ground conditions,
heating, and cooling requirements of the application and
system design.
Vertical ground loop — This system is used in vertical
borehole applications. This design is well suited for retrofit
applications where there are space limitations or where
landscaping is already complete and minimum disruption
of the site is desired. The vertical ground loop system
contains a single loop of pipe inserted into a hole. The
hole is back-filled and grouted after the pipe is inserted.
The completed loop is concealed below ground. The number of loops required depends on ground conditions, heating and cooling requirements, and the depth of each hole.
27
Application data (cont)
Hybrid systems — In some applications, it may be beneficial to incorporate a cooling tower into the ground loop
system to reduce the overall cost. A hybrid system discards
excess heat into the air and increases the cooling performance of the ground loop.
Water conditioning
In some applications, maintaining proper water quality
may require the use of higher corrosion protection for
the water-to-refrigerant heat exchanger. Water quality varies from location to location and is unique for each job.
Water characteristics such as pH value, alkalinity, hardness, and specific conductance are of importance when
considering any WSHP application. Water typically includes impurities and hardness that must be removed. The
required treatment will depend on the water quality as
well as type of system. Water problems fall into the following three main categories.
1. Scale formation caused by hard water reduces the
heat transfer rate and increases the water pressure
drop through the heat exchanger. As water is heated,
minerals and salts are precipitated from a solution and
deposited on the inside surface of the pipe or tube.
2. Corrosion is caused by absorption of gases from the
air coupled with water on exposed metal. Corrosion
is also common in salt-water areas.
3. Organic growths such as algae can reduce the heat
transfer rate by forming an insulating coating on the
inside tube surface. Algae can also promote corrosion
by pitting.
NOTE: In most commercial water loop applications,
Aquazone™ WSHP units use a copper water-to-refrigerant
heat exchanger. Units can also be equipped with a
cupronickel heat exchanger for applications where water is
outside the standard contaminant limits for a copper heat
exchanger.

Use cupronickel heat exchanger when concentrations of calcium or sodium
chloride are greater than 125 ppm are present. (Seawater is approximately
25,000 ppm.)
††If the concentration of these corrosives exceeds the maximum allowable level,
then the potential for serious corrosion problems exists.
Sulfides in the water quickly oxidize when exposed to air, requiring that no agitation occur as the sample is taken. Unless tested immediately at the site, the
sample will require stabilization with a few drops of one Molar zinc acetate solution, allowing accurate sulfide determination up to 24 hours after sampling. A
low pH and high alkalinity cause system problems, even when both values are
within ranges shown. The term pH refers to the acidity, basicity, or neutrality of
the water supply. Below 7.0, the water is considered to be acidic. Above 7.0,
water is considered to be basic. Neutral water contains a pH of 7.0.
To convert ppm to grains per gallon, divide by 17. Hardness in mg/l is equivalent to ppm.

Source vs. load heat exchanger
Both the load and source heat exchangers are water-torefrigerant heat exchangers. The water for the source heat
exchanger is supplied from a ground loop, open loop (well
water), or water loop (boiler/tower) system. Heat from the
refrigeration circuit is exchanged between the load and
source heat exchangers. The water for the load heat
exchanger can be used in many applications to provide
chilled or hot water for air-handling units, fan coils,
hydronic baseboards, radiant in-slab piping, or swimming
pools.

Series operation
Multiple units can be piped in a series type operation to
satisfy lower cooling leaving water temperature.
In a series operation, the leaving load water temperature
of the first unit becomes the load entering water temperature of the second unit. This arrangement provides an additional decrease in water temperature beyond the capability
of a single unit. For example, a typical drop of 5.5 C to
8.3 C can be accomplished with one 50PSW unit. When
2 or more units are piped in series, the water temperature
drop ranges between 11.1 C and 13.9 C. Capacity control
is provided by cycling one or more of the units on or off to
provide staging of the leaving water temperature from the
units.
When the load coils are piped in series, the total water
pressure drop through the load heat exchanger of the units
should include both units. This is a consideration when sizing the overall system, since an increase in pump horsepower may be required.

WATER OUT
Application systems exposed to outdoor temperatures below freezing (0° C) must be protected from freezing. The
most common method of protecting water systems from
freezing is adding glycol concentrations into the water. Design care should be used when selecting both the type and
concentrations of glycol utilized due to the following:
• Equipment and performance may suffer with high concentrations of glycol and other antifreeze solutions.
• Loss of piping pressure may increase greatly, resulting
in higher pumping costs.
• Higher viscosity of the mixture may cause excess corrosion and wear on the entire system.
• Acidity of the water may be greatly increased, promoting corrosion.
• Glycol promotes galvanic corrosion in systems of dissimilar metals. The result is corrosion of one metal by
the other, causing leaks.

Tempering ventilation air in air handlers
The load heat exchanger in a water-to-water unit provides
chilled water during the cooling season and hot water during the heating season. The source heat exchanger is used
to provide warm water for ventilation air reheat during the
cooling season. In the heating season, the source heat
exchanger uses heat from building exhaust to efficiently
produce hot water for heating ventilation air in the airhandling unit. The cooling and heating systems can be
either piped together for tempering ventilation air as part
of an overall integrated system with water-to-water units,
or implemented separately depending on the particular
design requirements for the ventilation air system.
NOTE: Depending on the system hydronic design, circulation pumps may be required for the source and load of the
water-to-water heat pumps in both heating and cooling
season operations.
Cooling season
On the load side of the 50PSW unit, chilled water is circulated to the air-handling unit where it cools and dehumidifies ventilation air. The water absorbs heat from the
ventilation air and returns to the 50PSW unit, where the
heat is removed via the refrigeration circuit and then transferred to the source heat exchanger. Heated water from
the source heat exchanger is used to reheat air in the ventilation unit. The heat is then absorbed from the water by
the air in the reheat coil and, if necessary, is returned to
the cooling tower, boiler, or ground loop for further heat
rejection.

Heating season
Building exhaust heat is used by the water-to-water unit for
hot water generation. On the load side of the heat
exchanger, hot water is circulated to the air-handling unit
for heating ventilation air. As the heat from the water is
released to the air, the water is circulated back to the
50PSW unit. On the source side of the unit, water is circulated through the heat recovery coil, picks up heat from the
exhaust airstream, and then circulates to the 50PSW unit.
A pair of control valves is required to maximize the process
of extracting the heat from the exhaust. Control valves on
the source heat exchanger supply and return water from
the main water loop to minimize (or possibly eliminate) the
need for additional heat injection by system boilers.

Hydronic heating/cooling system
with storage tank
In some cooling or heating applications, the addition of a
storage tank may be necessary. The tank allows hot or
chilled water temperatures to fluctuate, allowing the waterto-water heat pump to operate more consistently.
In heating applications, this prevents equipment short
cycling and allows different flow rates through the water-towater unit rather than through the hydronic heating delivery system.
A storage tank is also required for cooling applications if
the water-to-water unit is 20% larger than the cooling load
and/or multiple fan coil units in the same application.
NOTE: In cooling applications where only one fan coil is
utilized, water-to-water units may be able to operate without a storage tank.
The size of the storage tank should be based upon the
primary use of the application. For heating, storage tanks
should be sized at one U.S. gallon per 1,000 Btuh of heating capacity at the maximum entering source water temperature and the minimum entering load water temperature. For cooling, storage tanks should be sized at one U.S.
gallon per 1,000 Btuh of cooling capacity at the minimum
entering source water temperature and the maximum entering load water temperature. The selection of the storage
tank should be based upon the larger of the heating or
cooling calculations.
NOTE: When the water-to-water units do not have sufficient capacity to handle the required heating load, supplementary heating such as electric heat or a boiler may be
required.
Snow melting systems
Snow melting systems use water-to-water heat pumps to
melt snow and ice. The water-to-water heat pumps circulate hot water through a piping loop in a slab to melt ice
and snow. This system is especially energy efficient when
coupled with a geothermal ground loop for heat addition/
rejection. The size of the water-to-water heat pumps is
based on the amount of heat needed to melt the snow
across the surface.
NOTE: Consult the ASHRAE HVAC Applications Handbook for slab piping design and temperature requirements.
31
Application data (cont)
The 50PSW units can be configured with a field-supplied
control system for ice and snow melting. In commercial
applications where fast ice removal is required, keeping the
slab at a stationary temperature just below the freezing
point and then gradually increasing the hot water temperature may reduce melting time.
NOTE: To prevent thermal expansion of the slab due to
extreme temperature differences, hot water temperature
should be slowly increased.
