Regular maintenance or service to the console WSHP units require little time. Large service access panels enable

quick inspection for problem solving and the control box swings down for easy access to the controls.

Fan motor sleeve bearings are permanently lubricated for worry-free performance. If the unit does require service, an easily removable cabinet and slide out fan section make access simple.

Refrigerant circuit protection is designed to result in fewer service calls. Units are equipped with easily accessible service access ports on both the suction and the discharge refrigerant lines for on-site testing and environmentally correct refrigerant recovery. Filter racks provide easy filter access for cleaning.

Maximum control flexibility

Aquazone water source heat pumps provide reliable control operation using a standard microprocessor board.

Flexible alternatives for many direct digital control (DDC) applications include the Carrier Comfort Network (CCN) and open protocol systems.

Carrier’s Aquazone standard unit solid-state control system, the Complete C, provides control of the unit compressor, reversing valve, fan, safety features, and troubleshooting fault indication features. The Complete C 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:

Features/Benefits (cont)

Anti-short cycle 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 — 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 — Safeguards against

unreliable unit operation and prevents refrigerant from leaking.

Condensate overflow sensor — Electronic sensor mounted to the drain pan. When condensate pan liquid reaches an unacceptable level, the unit is automatically deactivated and placed in a lockout condition. The sensor recognizes thirty continuous seconds of overflow as a fault condition.

High and low voltage protection — Safety protection for excessive or low voltage conditions.

Automatic intelligent reset — Unit shall automatically restart 5 minutes after shutdown if the fault has cleared. Should a fault occur 3 times sequentially, lockout will occur.

Accessory output — In applications such as variable speed pumping, a 24-v output cycles a motorized water valve or damper actuator with compressor.

Performance Monitor (PM) — Unique feature monitors water temperatures to warn when the heat pump is operating inefficiently or beyond typical operating range. A field selectable switch initiates a warning code on the unit display.

Water coil freeze protection (selectable for water or antifreeze) — Field selectable switch for

water and water/glycol solution systems initiates a fault when temperatures exceed the selected limit for 30 continuous seconds.

Air coil freeze protection (check filter operation) — Field selectable

switch for assessing excessive filter pressure drop initiates a fault when temperatures exceed the selected limit for 30 continuous seconds.

Alarm relay setting — Selectable 24-v or pilot duty dry contact provides remote alarm activation.

Electric heat option — Output pro- vided on the controller for operating two stages of emergency electric heat.

Service test mode with diagnostic LED (light-emitting diode) — Tes t

mode allows service personnel to check the operation of the WSHP and control system efficiently. Upon entering Test mode, time delays speed up, and the Status LED flashes a code indicating the last fault. This mode provides easy fault diagnosis; based on the fault code the status LED flashes, Carrier provided troubleshooting tables provide 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 status.

Carrier PremierLink™ controller adds reliability, efficiency, and simplification

The PremierLink direct digital controller can be ordered as a factory-installed option. Designed and manufactured

exclusively by Carrier, the controller

can be used to actively monitor and

control all modes of operation as well

as monitor the following diagnostics

and features: unit number, zone tem-

perature, zone set point, zone humidity

set point, discharge air temperatures,

fan status, stages of heating, cooling

stages, outdoor-air temperature,

leaving-air temperature, leaving water

temperature, alarm status, and alarm

lockout condition.

This controller has 38.4K baud communications capability and is compatible with ComfortLink™ Controls, CCN and ComfortVIEW™ Software. The Scrolling Marquee and Navigator are optional tools used for programming and monitoring the unit for optimal performance. Adding the Carrier CO

sensor in the conditioned space

provides ASHRAE 62-99 compliance and Demand Control Ventilation (DCV). A DCV control strategy is especially beneficial for a water source heat pump system to minimize the energy used to condition ventilation air. In combination with energy efficient Aquazone units, DCV may be the most energy efficient approach ever developed for a water source heat pump system.

The PremierLink peer-to-peer, Internet ready communicating control is designed specifically for Constant Volume and Variable Volume Temperature applications. This comprehensive controls system allows water source heat pumps to be linked together, creating a fully functional HVAC (heating, ventilation, and air conditioning) automation system.

Options and accessories

Factory-installed options

Cupronickel heat exchangers are available for higher

corrosion protection for applications such as open tower, geothermal, etc. Consult the water quality guidelines for proper application and selection of this option.

Thermostat options include a unit mounted Manual Changeover (MCO) or Auto Changeover (ACO) thermostat. The temperature set point knob and push button switches for fan speed and cool/heat mode (MCO) selection are conveniently located on the top. The thermostat senses the return-air temperature. The thermostat sends the appropriate signal to the controller for cooling or heating mode of operation.

Options R and S allow connection to a remote wallmounted thermostat. The Complete C controller requires a heat pump thermostat. The Deluxe D controller can be configured for heat pump or heat/cool thermostat.

Extended range is provided to insulate the coaxial coil to prevent condensation, and therefore potential dripping problems, in applications where the entering water temperature is below the normal operating range (less than 60 F).

Cabinet options include a locking control panel for added security. Bottom or front return with left or right hand configurations are available for ease of installation. Available with 3 or 5 in. subbase, with or without motorized damper.

Motorized fresh air damper with the unit-mounted thermostat. Opens when LOW or HIGH fan speed selections are made from the push button switches. When STOP or FAN ONLY selections are made the spring return on the damper motor closes the damper. With remote thermostat the motorized fresh air damper opens when the fan is running.

Piping connections can be provided on either the right or left hand side of the unit, for easy installation. Orientation is determined by facing the unit from the front side.

Automatic flow regulators include internally mounted

2.25 or 3.0 gpm/ton automatic flow regulating valves for easier install

Two-way motorized control valve can be provided with a copper or cupronickel heat exchanger for applications involving open type systems or variable speed pumping. This valve will slowly open and close in conjunction with the compressor operation to shut off or turn on water to the unit. Standard two-way valve performance includes Cv of

2.9 and maximum operating pressure differential (MOPD) of 125 psi.

Mute package includes high density noise suppression material on front, right, and left sides of compressor compartment and insulated surfaces, for extra-quiet operation in the most critical applications.

Deluxe D control system provides the same functions as the Complete C while incorporating additional flexibility and functions to include:

Thermostat input capabilities shutdown mode and night setback with override (NSB) potential. Night setback from low temperature thermostat

Compressor relay staging (units with 2 compressors and 2 Deluxe D controls) or in master/slave applications.

Boilerless electric heat control system changeover to electric heat at low loop water temperature.

Intelligent reversing valve operation valve operation for extended life and quiet operation.

Thermostat type select (Y, O or Y, W) work and select heat pump or heat/cool thermostats (Y, W).

Reversing valve signal select (O or B) for heat pump O/B thermostats.

Dehumidistat input dehumidification operation.

Multiple units on one thermostat/wall sensor for communication for up to three heat pumps on one thermostat.

Boilerless changeover temperature boilerless changeover temperature set point.

Accessory relays cations including fan and compressor cycling, digital night setback (NSB), mechanical night setback, water valve operation, and outside air damper operation.

Night low limit either the push button switches, remote thermostat or the energy management system, it is possible that the space temperature could drop uncontrollably. The Night Low Limit feature, with Deluxe D controller, helps maintain the space temperature at a level that is the best compromise between energy consumption and a safe space temperature. A thermostat located near the return air filter activates the blower and compressor operation when the space temperature falls below 50 F. When return air temperature is raised above 55 F the compressor and blower stop.

Override function units operating in occupied/unoccupied mode under the control of an external timeclock or an energy management system. A contact closure from the timeclock or energy management system shorts the NSB and C terminal on the Deluxe D controller signaling an unoccupied mode.

For units with the unit-mounted thermostat, pressing override switch (located under control access door) will override the unoccupied mode and allow the occupied mode of operation to continue for a period of two hours.

The units with the remote wall-mounted thermostat require a digital thermostat with the override function. In unoccupied mode an accessory relay is energized on the Deluxe D controller. The NO/NC contacts of the relay can be used as appropriate input to the digital thermostat to signal occupied/unoccupied mode. The thermostat selects cooling/heating set points based on occupied/unoccupied mode.

PremierLink™ controller is compatible with the Carrier Comfort Network (CCN) and other building automation systems (BAS). This control is designed to allow users the access and ability to change factory-defined settings thus expanding the function of the standard unit.

Selection procedure (with 50KQL12 example)

I Determine the actual cooling and heating

loads at the desired dry bulb and wet bulb conditions.

Assume cooling load at desired dry bulb 80 F and wet bulb 66 F conditions are as follows:

Given:

Total Cooling (TC). . . . . . . . . . . . . . .11,750 Btuh

Sensible Cooling (SC) . . . . . . . . . . . . .8,650 Btuh

Entering-Air Temperature db . . . . . . . . . . . . 80 F

Entering-Air Temperature wb . . . . . . . . . . . . .66 F

II Determine the following design parameters.

Determine entering water temperature, water flow rate (gpm), airflow (cfm), water flow pressure drop and design wet and dry bulb temperatures. Airflow cfm should be between 300 and 450 cfm per ton. For applications using multiple units, the water pressure drop should be kept as close as possible across units to make water balancing easier. Enter the 50KQL12 Performance Data tables and find the proper indicated water flow and water temperature.

For example:

Entering Water Temp . . . . . . . . . . . . . . . . . 90 F

Water Flow (Based upon

10 F rise in temp) . . . . . . . . . . . . . . . . . . 3.1 gpm

Airflow Cfm . . . . . . . . . . . . . . . . . . . . . . 308 cfm

III Select a unit based on total cooling and total

sensible cooling conditions. Unit selected should be closest to but not larger than the actual cooling load.

Enter tables at the design water flow and water temperature. Read the total and sensible cooling capacities.

NOTE: Interpolation is permissible, extrapolation is not.

For example: Enter the 50KQL12 Performance Table at design

water flow and water temperature. Read Total Cooling, Sensible Cooling and Heat of Rejection capacities:

Total Cooling . . . . . . . . . . . . . . . . . .12,200 Btuh

Sensible Cooling . . . . . . . . . . . . . . . . 8,900 Btuh

Heat of Rejection . . . . . . . . . . . . . . .15,900 Btuh

NOTE: It is quite normal for water source heat pumps to be selected on cooling capacity only since the heating output is usually greater than the cooling capacity. Heating capacity is selected based on different entering water conditions than cooling capacity.

IV Determine the correction factors associated

with the variable factors of dry bulb and wet bulb using the Corrections Factor tables found in this book.

Using the following formulas to determine the correction factors of dry bulb and wet bulb:

a) Corrected Total Cooling = tabulated total cooling

x wet bulb correction x airflow correction.

b) Corrected Sensible Cooling = tabulated sensible

cooling x wet/dry bulb correction x airflow correction

V Determine entering air and airflow correction

using the Corrections Factor tables found in this book.

The nominal airflow for 50KQL12 is 350 cfm. The design parameter is 325 cfm.

308/350 = 88% of nominal airflow Use the 88% row in the Nominal Cfm Correction

table. The Entering Air Temperature wb is 66 F. Use the

66.2 F row in the Entering Air Correction table. Using the following formulas to determine the cor-

rection factors of entering air and airflow correction:

Table Ent Air Airflow Corrected

Corrected Total Cooling = 12,200 x 0.983 x 0.979 = 11,741

Corrected Sensible Cooling = 89,900 x 1.036 x 0.936 = 8,630

Corrected Heat of Rejection = 15,900 x 0.985 x 0.979 = 15,333

Compare the corrected capacities to the load requirements established in Step I. If the capacities are within 10% of the load requirements, the equipment is acceptable. It is better to undersize than oversize as undersizing improves humidity control, reduces sound levels and extends the life of the equipment.

VI Water temperature rise calculation and

assessment.

Calculate the water temperature rise and assess the selection using the following calculation:

Actual Temperature Rise

Correction of Heat Rejection

gpm x 500

For example, using the Corrected Heat of Rejection from the last step:

Actual Temperature Rise

3.1 x 500

15,333

=9.9 F

If the units selected are not within 10% of the load calculations, review what effect changing the gpm, water temperature and/or airflow will have on the corrected capacities. If the desired capacity cannot be achieved, select the next larger or smaller unit and repeat Steps I through VI.

VII ARI/ISO 13256-1 Conversion

Performance standard ARI/ISO 13256-1 became effective on January 1, 2000 and replaced the existing ARI Standards 320 Water-Loop Heat Pumps (WLHP), 325 Ground-Water Heat Pumps (GWHP), and 330 Ground-Loop Heat Pumps (GLHP).

The ARI/ISO Standard incorporates a consistent rating methodology for including fan and pump energy for calculating cooling capacity, heating capacity, and energy efficiency ratios (EER). This simplifies the use of rating data for heat pump performance modeling in seasonal energy analysis calculations, and allows for direct rating comparisons across applications.

a) ISO Capacity and Efficiency Equations

The following equations are used to calculate and correct cooling capacity, heating capacity, and respective EER:

ISO Cooling Capacity = (Cooling Capacity in Btuh) + (Fan Power Correction in Watts x 3.412)

ISO Cooling EER = (ISO Cooling Capacity in Btuh/3.412)/(Power Input in watts – fan power correction in watts + pump power correction in watts) = Watts/Watts

NOTE: Do not divide ISO Cooling Capacity by

3.412 to obtain Btuh/Watts. ISO Heating Capacity = (Heating Capacity in

Btuh) – (Fan Power Correction in Watts x 3.412) ISO Heating EER = (ISO Heating Capacity in

Btuh/3.412)/(Power Input in watts – fan power correction in watts + pump power correction in watts) = Watts/Watts

NOTE: Do not divide ISO Heating Capacity by

3.412 to obtain Btuh/Watts.

b) Identify the design conditions corrected for air and

water conditions. Airflow Cfm = 308 Cfm Water Flow

(Based upon 10 F rise in temp) = 3.1 GPM External Static Pressure = 0.0 in. wg (non-ducted

application) Water Pressure Drop = 3.7 ft of head Power input = 1,067 watts Cooling Capacity = 11,741 Btuh

c) Perform Fan Power Correction Adjustment

Use the following formula to calculate Fan Power Correction:

Fan Power Correction = (Cfm x 0.472) x (External Static

Pressure x 249)/300 = Watts

= (308 x 0.472) x (0 x 249)/300 = 0 Watts

d) Perform Pump Power Correction Adjustment

Use the following formula to calculate Pump Power Correction:

Pump Power Correction = (GPM x 0.0631) x (Pressure Drop

x 2,990)/300

= Watts

= (3.1 x 0.0631) x

(3.7 x 2,990)/300

= 7.2 Watts

e) Perform capacity and EER calculations

Use the following formula to calculate capacity and EER:

ISO Cooling Capacity = (Cooling Capacity) + (Fan Power

Correction x 3.412)

= 11,741 + (0 x 3.412) = 11,741 Btuh

f) Perform Corrections by using the ISO Equations

ISO EER = (ISO Cooling Capacity/3.412)/

(Power Input – Fan Power Correction + Pump Power Correction)

= Watts/Watts

NOTE: Do not divide ISO Cooling Capacity by

3.412 to obtain Btuh/Watts. = (11,741/3.412)/(1,067 – 0 + 7.2)

= 3.20 Watts/Watt = 10.93 Btuh/Watt

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, design this system between 2.25 and 3 gpm per ton 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 60 F and 90 F. Within this temperature range, units can heat or cool from the same water source. Transferring heat from warm to cold spaces in the building, whenever they coexist, conserves energy rather than creating new heat.

Refer to the Carrier Water Source Heat Pump Sys- tem Design Guide for assistance designing water loop systems. The guide includes a practical approach for the latest and most current design recommendations including:

• Horizontal, vertical, console, rooftop and water-to-

water product applications.

• Ventilation methods and system design including energy

recovery.

• Acoustical considerations for different product types.

• Addressing IAQ issues such as condensate removal,

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®.

• WSHP efficiency/operational cost comparison chart.

• System variations such as a system without a boiler, variable pumping, and VAV for interior use.

Ground water systems

To use Aquazone units in ground water applications, you should specify extended range. This will provide factoryinstalled coaxial coil insulation to prevent condensate from dripping when entering water temperatures are below 60 F. In addition, the copper coaxial coil installed on the Aquazone units may not be suitable for all 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 — Use this system 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 piping and excavation.

Aquazone units include a standard TXV and are rated to extremely low temperatures to self-adjust the refrigeration circuit. Therefore, open loop systems do not require water regulating valves. Use a slow opening/closing solenoid valve to conserve water.

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. This system only requires piping to get the water from the source to the unit.

NOTE: When utilizing Aquazone water source heat pumps in ground loop systems, refer to the design considerations in the ground water system section.

Horizontal ground loop — Use this system when adequate space is available and trenching can be easily accomplished. A series of parallel pipes are laid out in trenches 3 to 6 feet below the ground surface, and then back-filled. Often, multiple pipes are used to maximize each trench’s heat transfer capability. Ground conditions, heating and cooling requirements, and system design determine piping requirements and ground loop field size.

Vertical ground loop — Use this system in vertical borehole applications. This design is well suited for retrofit applications when space is limited or where landscaping is already complete and minimum site disruption 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

Page 23

concealed below ground. The number of loops required depends on ground conditions, heating and cooling requirements, and the depth of each hole.

Hybrid systems — In some applications, it may be bene- ficial 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.

Condensate drainage

Connect the console unit condensate drain to the building condensate drain with a flexible, non-pressure rate plastic hose. Be sure to avoid kinks in this hose to ensure an unobstructed flow of condensate from the unit to the drain. The condensate hose’s horizontal run is usually too short to pose any drainage problems, however, make sure this line is pitched at least 1 inch for every 10 feet of run (in the direction of the flow.) Avoid low points and unpitched piping since dirt collects in these areas and may cause stoppage and overflow.

Installing a trap or drain in the field is not required unless specified by local codes. The 50KQL units are designated in a blow-thru configuration. The condensate drain pan is located on the outlet side of the blower so that the pressure in the drain pan is higher than the atmospheric pressure.

Water conditioning

In some applications, maintaining proper water quality may require higher corrosion protection for the water-torefrigerant 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 important when considering any WSHP application. Water typically includes impurities and hardness that must be removed. The required treatment depends on the water quality as well as system type. Water problems fall into 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 copper water-to-refrigerant heat exchanger. Units can also be equipped with a Cupronickel heat exchanger for applications where water is outside the copper heat exchanger’s standard contaminant limits.

WATER QUALITY GUIDELINES

CONDITION ACCEPTABLE LEVEL

Total Hardness

Iron Oxides Less than 1 ppm. Iron Bacteria No level allowable.

Corrosion*

Brackish

*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 agita-

tion 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.

NOTE: To convert ppm to grains per gallon, divide by 17. Hardness in mg/l is equivalent to ppm.

7 to 9 range for copper. Cupronickel may be used in the 5 to 9 range.

Calcium and magnesium carbonate should not exceed 20 grains per gallon (350 ppm).

Acoustical design

Sound power levels represent the sound that the source, the WSHP unit, produces with no regard to attenuation between the source and the space. Acoustical design goals are necessary to provide criteria for occupied spaces. These goals help ensure that people can be comfortable and communicate effectively over the background noise of the airconditioning system and other background noise sources.

Acoustical design goals are desirable sound pressure levels within a given conditioned space and are represented by Noise Criteria (NC) curves. Noise Criteria (NC) curve levels represent a peak over a full frequency spectrum. A high value in a low frequency band has the same effect on NC level as a lower value in a high frequency band. It is important that sound levels be balanced over the entire spectrum relative to the NC curve. The lower the NC criteria curve, the more stringent the room acoustical design must be to meet the design goals.

It is important to know how to convert the unit ratings from sound power (Lw) to sound pressure (Lp). This conversion depends on the specifics of the installation’s acoustical environment. Assessing an area’s acoustical design requires that you compare the sound pressure (Lp) with the NC curve for the selected area.

The resulting calculations are compared to the NC curve selected for the area to assess the acoustical design.

Some of the factors that affect conversion of sound power to sound pressure and consequent NC level include:

• Type of acoustical ceiling

• Use of metal or flex duct

• Absorption in the occupied space

• Location in the occupied space

• Open or closed layout plan

• Use of open or ducted returns

• Orientation of unit to occupant

• Use of lined or unlined duct

Frequency (Hz)

WSHP sound control

Analyzing the projected sound level in the conditioned space caused by a WSHP unit is quite involved. The key is to have good sound power ratings (Lw) in dB on the equipment to determine the ductwork, ceiling and room sound attenuation effect.

Console units

With console units, the fan and compressor are located within the space, and only the casing design attenuates the transmission of sound sources into the space. The designer should carefully review the manufacturer’s acoustical data when selecting console units and use lower fan speeds to minimize space noise.

Operating limits

Environment

This equipment is designed for indoor installation ONLY.

Power supply

A voltage variation of ± 10% of nameplate utilization voltage is acceptable.

Starting conditions

The 50KQL unit will start and operate in an ambient temperature of 50 F, with entering air temperature at 50 F, with entering water temperature at 60 F, with both air and water at the flow rates used in the ARI/ISO Standard 13256-1 rating test, for initial start-up in winter.

NOTE: These are not normal or continuous operating conditions. Such a start-up should be used to bring the building space up to occupancy temperature.

1. Minimum Air and Water conditions can only be used at ARI/ISO 13256-1 flow rates.

2. The 50KQL units may have up two values at maximum or minimum with all other parameters at normal conditions.

Cooling Heating

Solenoid valves

In applications using variable flow pumping, solenoid valves can be factory installed and operated from the control board in the Aquazone™ WSHP unit.

Freeze protection

Applications where systems are exposed to outdoor temperatures below freezing (32 F) must be protected from freezing. The most common method of protecting water systems from freezing is adding glycol concentrations into the water. Use design care when selecting both the type and concentrations of glycol 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 mixture viscosity may cause excess corrosion and wear on the entire system

• The water’s acidity 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.
