Features/Benefits

AquaForce 30XA chillers provide best full load and part load performance in a single chassis from 80 to 500 tons.

Premium performance

The Aqua Series of chillers are Carrier’s most efficient air-cooled models. The AquaForce chiller is one of the most affordable air-cooled chillers to operate (and maintain). The AquaForce chiller offers full load EER (Energy Efficiency Ratio) up to 10.7 and IPLV (Integrated Part-Load Value) up to 15.1. High-efficiency rotary screw compressors with infinitely variable slide valves allow the chillers to exactly match actual load conditions, delivering exceptional part load performance. The AquaForce chillers will deliver superior efficiency through all operating ranges to keep costs and demand charges down. This exceptional performance will have a significant impact on energy savings and cost of ownership.

AquaForce™ chillers’ quiet operation make them ideal for sound sensitive applications

Great performance is delivered in a low sound unit that will be quiet enough for any application including hospitals, schools and other sites located in residential neighborhoods. The AquaForce chiller’s AeroAcoustic™ fan is almost twice as quiet as the competition’s per cfm. During part load operation, when units operate with fewer fans, means even quieter operation in cooler weather and during nighttime operation.

Built in reliability

AquaForce chillers were developed under one of the most exacting qualification programs ever used for commercial chiller products. The compressors are virtually maintenance-free and protected by an auto-adaptive control that minimizes compressor wear. Operate AquaForce chillers year-round from –20 F (–29 C) to 125 F (52 C), with a combination of options and control methods. The following features are also provided to help ensure reliable performance:

Multiple independent circuits

provide redundancy and greater reliability.

Electronic expansion valve (EXV)

allows for precise control through all operating ranges.

Highly efficient, reliable chilled water circuit

AquaForce chillers provide a comprehensive chilled water circuit utilizing a high efficiency shell-in-tube flooded cooler. Units are equipped with a 100% drainable cooler.

Electronic thermal-dispersion flow switch is included with the cool-

er. The switch is factory installed and tested and contains no moving parts for high reliability.

Environmentally sound

R-134a refrigerant enables you to make a responsible choice in helping to preserve the environment. R-134a refrigerant is an HFC refrigerant that does not contain ozone-layer damaging chlorine. R-134a refrigerant is unaffected by the Montreal Protocol. R-134a refrigerant is a safe, nontoxic, efficient and environmentally sound refrigerant.

Easy installation

A single chassis design provides a one-piece unit from 80 to 500 tons. The base rail is industrial-quality

/4-in. cold-rolled steel for maximum structural integrity. The zinc-dipped and painted galvanized frame provides protection for corrosion

resistance. With such a structurally sound base, no perimeter mounting rail is needed.

ComfortLinkTM controls for ease of use

The ComfortLink controls communicate in plain English, making it as easy as possible to monitor and control each AquaForce chiller while accurately maintaining fluid temperatures. Carrier 30 Series chillers’ ComfortLink controls provide features such as chilled water temperature reset, demand limiting, compressor wear minimization and protection, temperature and pressure displays and diagnostic functions. These controls result in higher chiller reliability, simplified training and more productive service calls with correspondingly lower operational and maintenance costs.

Carrier's exclusive handheld Navigator™ display provides convenience and powerful information in the palm of your hand. The Navigator display helps technicians to quickly diagnose problems and even prevent them from occurring.

All AquaForce units are ready to be used with the Carrier Comfort Network (CCN).

Factory-installed options

Condenser coil options are available to match coil con-

struction to the site conditions for the best durability. Refer to the Condenser Coil Corrosion Protection Options table on page 11 or the Environmental Corrosion Protection white paper for more information.

High ambient temperature option provides highspeed condenser fan motors to increase the condenser airflow. This option may allow for an increase in machine capacity, and may also result the selection of a smaller chassis to meet given capacity requirements. The high ambient temperature option is not available on 30XA080120 units.

Minus-one-pass cooler provides a lower pressure drop through the cooler for applications with low delta T or high flow or where the coolers are piped in a series.

Plus-one-pass cooler provides a greater efficiency for brine applications and in applications with a high delta T and low flow.

Wye-delta start is an alternate starting method which reduces the in-rush current when starting the compressor.

Compressor suction service valve provides additional protection. Standard refrigerant discharge isolation and liquid valves enable service personnel to store the refrigerant charge in the cooler or condenser during servicing. This factory-installed option allows for isolation of the compressor from the cooler vessel.

Energy management module provides energy management capabilities to minimize chiller energy consumption. Several features are provided with this module including leaving fluid temperature reset, cooling set point reset or demand limit control from a 4 to 20 mA signal, 2-step demand limit control (from 0 to 100%) activated by a remote contact closure, and discrete input for “Ice Done” indication for ice storage system interface.

Service option provides a remote service port for

ITEM FACTORY-INSTALLED OPTION FIELD-INSTA LLE D ACCE SSORY

convenience outlet that includes 4-amp GFI (Ground Fault Interrupt) receptacle. Convenience outlet is 115-v female receptacle. Service option not available with 380-v units, and is also available as a field-installed accessory.

Low ambient temperature

head pressure control

permits operation of the 30XA units to –20 F (–29 C) outdoor ambient temperature. The control is also available as a field-installed accessory and may require field-installed wind baffles.

Medium temperature brine option allows for leaving fluid temperatures to be set between 15 and 39 F (–9.4 to

3.9 C). The expansion device is modified to correct for the lower refrigeration flow rates. Low ambient temperature head pressure control and suction line insulation are required.

Unit-mounted non-fused disconnect option provides non-fused disconnect for unit power located at the unit.

BACnet™ translator control provides an interface between the chiller and a BACnet Local Area Network (LAN, i.e., MS/TP EIA-485). The BACnet translator control is also available as a field-installed accessory.

LON translator control provides an interface between the chiller and a Local Operating Network (LON, i.e., LonWorks FT-10A ANSI/EIA-709.1). The LON translator control is also available as a field-installed accessory.

Condenser coil trim panels provide an aesthetic, finished appearance for the condenser coil ends of the compressor side of the unit. Condenser coil trim panels are also available as a field-installed accessory.

Control transformer is sized to supply the needs of the control circuit from the main power supply. The control transformer is also available as a field-installed accessory.

Remote service port consists of a receptacle for Navigator™ device connection. The port is housed in a waterproof enclosure conveniently located for easy access to information during operation and maintenance routines.

Navigator™ display connection and a factory-installed

Control transformer is sized to supply the needs of the

control circuit from the main power supply. The control transformer is also available as a factory-installed option.

Remote enhanced display is a remotely mounted indoor 40-character per line, 16-line display panel for unit monitoring and diagnostics.

Chillervisor System Manager III multi-unit control

allows sequencing of between two and eight chillers in parallel.

Low ambient temperature head pressure control

permits operation of the 30XA units to –20 F outdoor ambient temperature. The control is also available as a factory-installed option and may require field-installed wind baffles.

Energy Management Module provides energy management capabilities to minimize chiller energy consumption. Several features are provided with this module including leaving fluid temperature reset, cooling set point reset or demand limit control from a 4 to 20 mA signal, 2-step demand limit control (from 0 to 100%) activated by a remote contact closure (one-step demand limit does not require the Energy Management Module), and discrete input for “Ice Done” indication for ice storage system interface.

Remote service port consists of a receptacle for Navigator™ device connection. The port is housed in a

waterproof enclosure conveniently located for easy access to information during operation and maintenance routines.

Convenience outlet includes 4-amp GFI (Ground Fault Interrupt) receptacle. Convenience outlet is 115-v female receptacle. Not available with 380-v units.

Selection procedure

Carrier’s Packaged Chiller Builder Selection Program provides quick, easy selection of Carrier’s air-cooled liquid chillers. The program considers specific temperature, fluid and flow requirements among other factors such as fouling and altitude corrections.

Before selecting a chiller, consider the following points:

Leaving water temperature (LWT)

• If the LWT is less than 40 F (4.4 C), loop freeze protection to a minimum of 15° F (8.3° C) below the LWT set point is required. The medium temperature brine option is also required.

• If the LWT requirement is greater than 60 F (15.5 C), a mixing loop is required.

Entering water temperature (EWT)

• If the EWT requirement is greater than 70 F (21.1 C), a mixing loop is required. The EWT should not exceed 70 F (21.1 C) for extended operation. Pulldown can be accomplished from 95 F (35 C).

Cooler flow rate or cooler delta-T:

• The cooler delta-T (EWT – LWT) must fall between 5 and 20° F (2.8 to 11.1° C).

• For larger or smaller delta-T applications, a mixing loop is required.

• If the cooler flow is variable and the rate of change of flow should not exceed 10% per minute, a loop volume of greater than 3 gallons per ton (3.2 l/kW) is recommended.

Cooler pressure drop:

• A high cooler pressure drop can be expected when the cooler delta-T is low. A mixing loop can help to alleviate this situation.

Alternatively, consider a reduced pass option for a lower delta-T.

• A low cooler pressure drop can be expected when

cooler delta-T is high.

• Consider the plus-one-pass cooler option to increase

delta-T and performance.

Water quality, fouling factor:

• Poor water quality can increase the required cooler fouling factor.

• Higher than standard fouling factors lead to lower capacity and higher input kW from a given chiller size compared to running the same application with better quality water (and lower fouling factors).

Operation below 32 F (0° C):

• Low ambient temperature head pressure control is required.

• Consider wind baffles if average wind speed is greater than 5 mph (8 km/h).

• Consider higher loop volumes, 6 to 10 gallons per nominal ton (6.5 to 10.8 l/kW).

• Loop freeze protection with glycol is strongly recommended to a minimum of 15° F (8.3° C) below lowest anticipated ambient temperature.

• Chilled water pump control is strongly recommended; otherwise override capability is required.

Chiller idle below 32 F (0° C):

• Loop freeze protection with glycol is strongly recommended to a minimum of 15° F (8.3° C) below lowest anticipated ambient temperature.

• Chilled water pump control is strongly recommended; otherwise override capability is required.

• Drain the cooler — This will require a small amount of glycol for residual water. Cooler heaters will need to be disconnected.

• Highest allowable ambient air temperature is 125 F (52 C).

NOTE: It may be necessary to select the high ambient option to obtain performance with ambient air temperatures approaching 125 F (52 C).

Cooling capacity requirement:

• Do not oversize the chillers by more than 15% at design conditions.

• If capacity control is required below the standard minimum step of unloading, the minimum load control option should be employed. (See Selection Guide.)

Coil corrosion requirements:

• Coastal application

• Industrial application

• Coastal/industrial application

• Urban application

•Farming

Temperature reset:

• Return water (standard)

• Outside air temperature (standard)

• Space temperature (accessory sensor required)

• 4 to 20 mA (requires an Energy Management Module)

Demand limit:

• 2-step (requires an Energy Management Module)

• 4 to 20 mA (requires an Energy Management Module)

• CCN Loadshed

Microprocessor

The ComfortLink™ microprocessor controls overall unit operation and controls a number of processes simultaneously. These processes include internal timers, reading inputs, analog to digital conversions, fan control, display control, diagnostic control, output relay control, demand limit, capacity control, head pressure control, and temperature reset. Some processes are updated almost continuously, others every 2 to 3 seconds, and some every 30 seconds. The microprocessor routine is started by switching the Emergency ON-OFF switch to ON position. Pump control of external pumps (where configured) will energize the cooler pump to the internal (or CCN) time schedule (or input occupied signal from external system).

When the unit receives a call for cooling (based on a deviation from chilled water set point), the unit stages up in capacity to maintain the cooler fluid set point. The first compressor starts 1 to 3 minutes after the call for cooling. The ComfortLink microprocessor controls the capacity of the chiller by varying the number of compressors on and each loading capacity to satisfy actual dynamic load conditions. The control maintains leaving-fluid temperature set point shown on the Navigator™ device through intelligent positioning of the slide valve and compressor cycling. Accuracy depends on loop volume, loop flow rate, load, and outdoor-air temperature. No adjustment for cooling range or cooler flow rate is required, because the control automatically compensates for cooling range by measuring both return-fluid temperature and leaving-fluid temperature. This is referred to as leaving-fluid temperature control with return-fluid temperature compensation.

The basic logic for determining when to add or remove capacity is a time band integration of deviation from set point plus rate of change of leaving-fluid temperature. When leaving-fluid temperature is close to the set point and slowly moving closer, logic prevents additional capacity. If leaving-fluid temperature is less than 34 F (1.1 C) for water, or 6° F (3.3° C) below the brine freeze set point for brine units, the unit is shut off until the water temperature for brine reaches 34 F (1.1 C) or to 6° F (3.3° C) above the set point for brine to protect against freezing.

If pulldown control has been selected (adjustable setting), no additional capacity is added as long as the difference between leaving-fluid temperature and the set point is greater than 4° F (2.2° C) and rate of change in leavingwater temperature is greater than the adjustable setting. If it has been less than 90 seconds since the last capacity change, compressors will continue to run unless a safety device trips. This prevents rapid cycling and also helps return oil during short operating periods.

Control sequence

Off cycle — If ambient temperature is below 36 F (2.2 C),

cooler heaters are also energized. Start-up — After control circuit switches on, the prestart

process takes place, then microprocessor checks itself, starts pump (if configured) and waits for temperature to stabilize. The controlled pulldown feature limits compressor loading on start-up to reduce demand on start-up and unnecessary compressor usage.

Capacity control — On the first call for cooling, the microprocessor starts initial compressor and fan stage on lead circuit.

As additional cooling is required, the capacity of the compressor is increased by changing the position of the slide valve. As the load increases above the compressor’s capacity, another compressor is started and both staged together.

The speed at which capacity is added or reduced is controlled by temperature deviation from set point and rate of temperature change of chilled fluid.

The Main Base Board (MBB) responds to the supply chilled water temperature to cycle the compressors to match cooling load requirements.

The Minimum Load control valve is energized by the MBB. The valve allows hot gas to pass directly into the cooler circuit on the initial step of unloading, permitting the unit to operate at lower loads with less compressor cycling.

Sensors

Thermistors are used to control temperature-sensing inputs to the microprocessor. No additional thermistor sensors are required for optional leaving chilled water temperature, return water, or outdoor air reset.

The following sensors can be used on 30XA units:

• Cooler leaving chilled fluid temperature (T1)

• Cooler entering fluid (return) temperature (T2)

• Outside-air temperature (T9)

• Space Temperature (T10)

Two refrigerant pressure transducers are used in each circuit for sensing suction and discharge pressure. The microprocessor uses these inputs to control capacity and fan cycling.

• Saturated condensing temperature

• Cooler saturation temperature

•Oil

•Economizer

Additional information

Detailed information on controls and operation is available in the Controls, Start-Up, Operation, Service, and Troubleshooting guide included with each unit. Packaged Service Training programs are also available. Contact a local Carrier representative for more information.

Dynamic ComfortLink controls keep the chiller on line during periods of extreme operating conditions. If the entering fluid temperature is 95 F (35 C) and the saturated suction temperature is 50 F (10 C) or higher the maximum operating pressure (MOP) feature limits the suction to keep the chiller online. The control automatically starts the chiller in the unloaded state to eliminate the potential of compressor overload due to high head pressure or low suction pressure. The controller will equalize run time on each circuit through the lead/lag feature. If a circuit becomes disabled, the control will automatically set the active circuit to lead, keeping the chiller online at a reduced capacity.

Page 42

Controls (cont)

Standard ComfortLink™ controls with Navigator™ display — A portable hand-held display for convenient

access to unit status, operation, configuration and troubleshooting diagnostics capability is standard on 30XA units. The four-line, 20-character LCD display provides clear language information in English, French, Spanish, or Portuguese. The weatherproof enclosure and industrial grade extension cord enable the Navigator display to be ideally suited for outdoor applications. Magnets located on the back of the module allow attachment to any sheet metal component for hands-free operation.

Low-temperature override — This feature prevents LCWT (leaving chilled water temperature) from overshooting the set point and possibly causing a nuisance trip-out by the freeze protection.

High-temperature override — This feature allows the chiller to add capacity quickly during rapid load variations.

Temperature reset

The Energy Management Module is required for 4 to 20 mA reset of LCWT in constant fluid systems. Reset by return fluid, outdoor-air temperature, or space temperature does not require this option. Reset reduces compressor power usage at part load when design LCWT is not necessary. Humidity control should be considered since higher coil temperatures resulting from reset will reduce latent heat capacity. Three reset options are offered, based on the following:

Return-Fluid Temperature return (or entering) fluid temperature decreases (indicating load decrease). Option may be used in any application where return fluid provides accurate load indication. A limitation of return fluid reset is that LCWT may only be reset to value of design return fluid temperature.

Outdoor-Air Temperature ambient temperature decreases (indicating load decrease). This reset should be applied only where outdoor ambient temperature is an accurate indication of load.

Space Temperature ature decreases (indicating load decrease). This reset should be applied only where space temperature is an accurate indication of load. An accessory space temperature thermistor is required.

For details on applying a reset option, refer to the Controls, Start-Up, Operation, Service and Troubleshooting literature shipped with the unit. Obtain ordering part numbers for reset option from the Packaged Chiller Builder program or contact a local Carrier representative.

Abnormal conditions — All control safeties in the chiller operate through compressor protection board or control relay and microprocessor.

Loss of feedback signal to the MBB will cause the compressor(s) to shut down. For other safeties, microprocessor makes appropriate decision to shut down a compressor due to a safety trip or bad sensor reading and displays appropriate failure code on the display. Chiller holds in safety mode until reset; it then reverts to normal control when unit is reset.

Low-pressure safety — Safety cuts out if system pressure drops below minimum.

High-pressure cutout — Switch shuts down compressors if compressor discharge pressure increases to 305 psig (2102.7 kPa).

Compressor anti-cycling — This feature limits compressor cycling.

Loss of flow protection — Proof of flow switches are standard and installed on all 30XA chillers.

Sensor failures — Failures are detected by the microprocessor.

Accessory controls — Demand can be limited by controlling the chiller capacity through the demand limit control (the Energy Management Module is required for this function). This FIOP/accessory interfaces with the microprocessor to control the unit so that the chiller’s kW demand does not exceed its setting. It is activated from an external switch or a 4 to 20 mA signal.

The standard ComfortLink control is programmed to accept various accessory temperature reset options (based on outdoor-air temperature [standard], return-fluid temperature [standard], or space temperature [which requires accessory thermistor]), that resets the LCWT. An accessory thermistor (T10) is required if space temperature reset is selected. The Energy Management Module (EMM) is only required for temperature reset that is initiated by a 4 to 20 mA signal.

Demand limit — If the demand limit is applied, it limits the total power draw of unit to a selected point by controlling the number of operational compressors during periods of peak electrical demand.

The Energy Management Module is required for either 2-step or 4 to 20 mA demand limit.

Electronic expansion valve (EXV) — The EXV controls refrigerant flow to the cooler for different operating conditions by varying an orifice size to increase or decrease the flow area through the valve based on microprocessor input. The orifice is positioned by a stepper motor through approximately 3,600 discrete steps and is monitored every three seconds.

Diagnostics — The microprocessor may be put through a service test (see Controls, Start-Up, Operation, Service, and Troubleshooting literature). Service test confirms microprocessor is functional, informs observer through display the condition of each sensor and switch in chiller, and allows observer to check for proper operation of fans and compressors.

Default settings — To facilitate quick start-ups, 30XA chillers with ComfortLink controls are pre-configured with a default setting that assumes stand-alone operation supplying 44 F (6.6 C) chilled water.

Configuration settings will be based on any options or accessories included with the unit at the time of manufacturing.

Date and time are set to U.S.A. Eastern Time zone and will need reconfiguring based on location and local time zone. If operation based on occupancy scheduling is desired, schedule must be set during installation.

Page 43

Ice duty — ComfortLink™ controls have the capability of reduced leaving fluid temperature operation for thermal storage, or ice duty. The optional Energy Management display includes input contacts for the “ice done” signal generated by the thermal storage control system. The ice duty feature may be configured to start on an external input command or by the ComfortLink standard internal scheduling function. The ice duty function requires brine modification for leaving fluid temperatures below 40 F (4.4 C). Ice duty may be used in combination with any other standard features offered by the Energy Management Module and ComfortLink controls.

The production of ice, which is stored for peak cooling demands, can significantly decrease energy costs. The unit produces ice (normally at night) by supplying ice storage tanks with low temperature cooling fluid. The chiller takes advantage of reduced ambient conditions at night for icemaking mode, so the capacity suffers a lower penalty for the low leaving fluid temperatures.

At peak cooling demands, the chiller and the stored ice may share the cooling load to reduce operating costs. The thermal storage system may potentially reduce the size of the chiller plant required to meet demand loads.

Application data

Chiller location and clearances

Do not locate near sound sensitive areas without proper acoustic consideration. For applications requiring mounting a chiller on a building rooftop, consideration should be given to using rubber-in-shear or spring isolators to minimize structure-borne transmission. Unit must be level when installed to ensure proper oil return to the compressors. Clearances must be provided around chillers for airflow, service and local code requirements. See dimensional drawings for specific unit clearance requirements. Ensure adequate clearance between adjacent chillers is maintained. A minimum of 10 ft is recommended. Chiller fan discharge must be at least as high as adjacent solid walls. Installation in pits is not recommended.

Strainers

A strainer with a minimum screen size of 20 mesh must be installed in the entering cooler fluid line, no more than 10 ft ahead of the cooler.

Oversizing chillers

Oversizing chillers by more than 15% at design conditions must be avoided as the system operating efficiency is adversely affected (resulting in greater or excessive electrical demand). When future expansion of equipment is anticipated, install a single chiller to meet present load requirements and add a second chiller to meet the additional load demand. It is also recommended that 2 smaller chillers be installed where operation at minimum load is critical. The operation of a smaller chiller loaded to a greater percentage over minimum is preferred to operating a single chiller at or near its minimum recommended value. Minimum Load Control should not be used as a means to allow oversizing chillers. Minimum Load Control should be given consideration where substantial operating time is anticipated below the minimum unloading step.

Cooler water temperature

1. Maximum leaving chilled water temperature (LCWT) for the unit is 60 F (15.5 C). Unit can start and pull down with up to 95 F (35 C) entering-water temperature. It is recommended that entering-water temperature not exceed 70 F (21.1).

2. Minimum LCWT for a standard unit is 40 F (4.4 C). For leaving-water temperatures between 15 and

39.9 F (–9.4 to 43 C) an inhibited antifreeze solution is required. Application of chiller to 15 F (–9.4 C) is possible by ordering the factory-installed medium temperature brine option.

NOTE: Water flowing through cooler should not exceed 100 F.

Cooler flow/range

Ratings and performance data in this publication are for a cooling temperature rise of 10° F (5.5° C). The 30XA chillers may be operated at a different temperature rise, providing flow limits are not exceeded and corrections to system guidelines are made. For minimum and maximum cooler flow rates, see the Minimum and Maximum Cooler Flow Rates table. A high flow rate is generally limited by the maximum pressure drop that can be tolerated by the unit. The 30XA chillers are designed for a full load temperature rise of 5° to 20° F (2.8° to 11.1° C). Use the Packaged

Chiller Program to obtain the rating if a temperature rise other than 10° F (5.5° C) is used.

Minimum cooler flow (maximum cooler temperature rise) — The minimum cooler flow for standard units

is shown in the Minimum and Maximum Cooler Flow Rates table. When system design conditions require a lower flow (or higher rise) than the minimum allowable cooler flow, follow the recommendations below.

a. Multiple smaller chillers may be applied in series, each

providing a portion of the design temperature rise.

b. Cooler fluid may be recirculated to raise the flow rate to

the chiller. However, the mixed temperature entering cooler must be maintained a minimum of at least 5 F (2.8 C) above the LCWT.

NOTE: Recirculation flow is shown below.

RECIRCULATION FLOW

Maximum cooler flow — The maximum cooler flow

(approximately 5° F rise) results in a practical maximum pressure drop through cooler.

Return fluid may bypass the cooler to keep the pressure drop through the cooler within acceptable limits. This permits a higher delta T with lower fluid flow through cooler and mixing after the cooler.

NOTE: Bypass flow is shown below.

BYPASS FLOW

Variable cooler flow rates

Variable rates may be applied to a standard chiller. The unit will, however, attempt to maintain a constant leaving chilled water temperature. In such cases minimum flow must be in excess of minimum flow given in the Minimum and Maximum Cooler Fluid Flow Rates table, and minimum water volume must be in excess of 3 gallons per ton (3.2 l/kw). Flow rate must change in steps of less than 10% per minute. Apply 6 gal. or more per ton (6.5 l/kw) water loop volume minimum if flow rate changes more rapidly.

Page 46

Application data (cont)

Water loop volume

The volume in circulation must equal or exceed 3 gal. per nominal ton (6.5 l/kW) of cooling for temperature stability and accuracy in normal air conditioning applications. In process cooling applications, or for operation at ambient temperature below 32 F (0° C) with low loading conditions, there should be from 6 to 10 gal. per ton (6.5 to

10.8 l/kW). To achieve this volume, it is often necessary to install a tank in the loop.

Tank should be baffled to ensure there is no stratification and that water (or brine) entering tank is adequately mixed with liquid in the tank.

Cooler freeze protection

Freeze protection for the cooler is standard on all 30XA air-cooled chillers. All units are equipped with cooler heaters. Units are protected from freezing down to 0° F (–18 C) through the cooler heaters and control algorithms. If a unit controls the chilled water pump/valves, allowing for flow through the cooler, the unit is protected from freezing down to –20 F (–29 C). Since power is sometimes lost for extended periods during winter storms, freeze protection provided by heater tapes will be effective only if a back-up power supply can be assured for the unit’s control circuit, heater and cooler pump. If not protected with an antifreeze solution, draining the cooler and outdoor piping is recommended if the system will not be used during freezing weather conditions.

Two conditions that must be considered when determining antifreeze concentration are both leaving water set point and ambient freeze conditions. Both of these parameters can help determine the recommended concentration level. Higher concentration must be used to adequately protect the machine.

NOTE: Use only antifreeze solutions approved for heat exchanger duty.

For applications in which the leaving water temperature set point is less than 40 F (4.4 C), a suitable inhibited antifreeze solution must be used. The solution concentration must be sufficient to protect the chilled water loop to a freeze protection (first crystals) concentration of at least 15° F (8.3° C) below the leaving water temperature set point.

If the chiller refrigerant or fluid lines are in an area where ambient conditions fall below 34º F (1.1º C), it is required that an antifreeze solution be added to protect the unit and fluid piping to a temperature of 15º F (8.3° C) below the lowest anticipated ambient temperature.

Select concentration based on either burst or freeze protection as dictated by the application. If the chiller does not operate during the winter, nor is a start-up expected, a burst protection concentration is recommended. This concentration may not be high enough to pump the fluid through the unit. Burst protection is typically a lower concentration that will provide better performance from the machine. If the chiller does operate during winter, a freeze protection concentration is recommended. This concentration will be high enough to keep the fluid in a condition that it can be pumped at low ambient conditions.

IMPORTANT: Glycol anti-freeze solutions are highly recommended since heater tapes provide no protection in the event of a power failure.

Consult glycol fluid manufacturers for burst protection recommendations and fluid specifications.

High ambient temperature operation

High outdoor ambient chiller start-up and operation is possible for standard 30XA chillers at ambient temperatures up to 125 F (52 C) at nominal voltage.

Low ambient temperature operation

Units will start and operate down to 32 F (0° C) as standard. Operation to –20 F (–29 C) requires optional low ambient head pressure control as well as wind baffles (field fabricated and installed to all units for operation below 32 F [0° C]) if wind velocity is anticipated to be greater than 5 mph (8 kp/h). Inhibited propylene glycol or other suitable corrosion-resistant anti-freeze solution must be field supplied and installed in all units for unit operation below 34 F (1.1 C). Solution must be added to fluid loop to protect loop down to 15° F (8.3° C) below minimum operating ambient temperature. Concentration should be based on expected minimum temperature and either “Burst” or “Freeze” protection levels. At least 6 gal per ton (6.5 l/kw) of water volume is the recommended minimum for a moderate system load.

Multiple chillers

Where multiple chillers are required, or where standby capability is desired, chillers may be installed in parallel. Units may be of the same size or different sizes. However, cooler flow rates must be balanced according to the recommendations for each chiller to ensure proper flow.

Unit software is capable of controlling two units as a single plant. Refer to the Controls, Start-Up, Operation, Service, and Troubleshooting guide for further details.

Dual chiller control

The ComfortLink™ controller allows 2 chillers (piped in parallel or series) to operate as a single chilled water plant with standard control functions coordinated through the master chiller controller. This standard ComfortLink fea- ture requires a communication link between the 2 chillers.

There are several advantages to this type of control:

• Redundancy (multiple circuits)

• Better low load control (lower tonnage capability)

• Lower rigging lift weights (2 machines rather than

1 large machine)

• Chiller Lead-Lag Operation (evens the wear between

the two machines)

Parallel dual chiller operation — Parallel Chiller Operation is the recommended option for Dual Chiller Control. In this case, each chiller must control its own dedicated pump or isolation valve. Balancing valves are recommended to ensure proper flow in each chiller. Two fieldsupplied and installed dual chiller leaving water temperature sensors are required, one for each module, for this function to operate properly.

Consider adding additional isolation valves to isolate each chiller to allow for service on a machine, and still allow for partial capacity from the other chiller.

Series dual chiller operation — Series Chiller Operation is an alternate control method supported by the ComfortLink control system. Certain applications might

require that the two chillers be connected in series. For nominal 10 F (5.6 C) cooler ranges, use the Minus 1 Pass Cooler arrangement to reduce the fluid-side pressure drop. Use the standard cooler pass arrangement for low flow, high cooler temperature rise applications. Two fieldsupplied and installed dual chiller leaving water temperature sensors are required, one for each module, for this function to operate properly.

Consider adding additional piping and isolation valves to isolate each chiller to allow for service on a machine, and still allow for partial capacity from the other chiller.

Condenser coil protection (Enviro-Shield™)

Refer to the Environmental Corrosion Protection white paper for more information.

Pre-coated aluminum-fin coils have a durable epoxyphenolic coating applied to the fin prior to the fin stamping process to provide protection in mildly corrosive coastal environments. Pre-coated coils have an inert barrier between the aluminum fin and copper tube. This barrier electrically disconnects the dissimilar metals to minimize the potential for galvanic corrosion. This economical option provides substantial corrosion protection beyond the standard uncoated coil construction.

Copper-fin coils provide increased corrosion resistance in moderate coastal environments where industrial air pollution is not present. All copper coils eliminate bimetallic construction to eliminate the potential for galvanic corrosion. Application in industrial environments is not recommended due to potential attack from sulfur, sulfur oxide, nitrogen oxides, carbon and several other industrial airborne contaminants. In moderate seacoast environments, copper-fin coils have extended life compared to standard or pre-coated aluminum-fin coils.

E-coated aluminum-fin coils have an extremely flexible and durable epoxy coating uniformly applied to all coil surfaces. Unlike brittle phenolic dip and bake coatings, E-coat provides superior protection with unmatched flexibility, edge coverage, metal adhesion, thermal performance and most importantly, corrosion resistance. E-coated coils provide this protection since all coil surfaces are completely encapsulated from environmental contamination. Specify E-coated aluminum-fin coils for industrial environments with high levels of air pollution. This option also provides better protection compared to standard or pre-coated aluminum-fin coils in industrial environments.

E-coated copper-fin coils have the same flexible and durable epoxy coating as E-coated aluminum-fin coils. However, this option combines the natural salt and environmental resistance of all-copper construction with the highest level of corrosion protection. Specify E-coated copper-fin coils in the harshest combination of coastal and industrial environments.

Electrical/utility interests

Energy management — Use of energy management

practices can significantly reduce operating costs, especially during off-peak modes of operation. Demand limiting and temperature reset are two techniques for accomplishing efficient energy management. See Demand Limiting (also called load shedding) section below for further details.

Page 49

Demand limiting (load shedding)

When a utility’s demand for electricity exceeds a certain level, loads are shed to keep electricity demand below a prescribed maximum level. Typically, this happens on hot days when air conditioning is most needed. The Energy Management Module (EMM) can be added to accomplish this reduction. Demand may be limited on the unit by resetting water temperature, or by unloading the chiller to a given predetermined percentage of the load. Demand limit may also be driven by an external 4 to 20 mA signal. These features require a signal from an intelligent central control. Do not cycle demand limiter for less than

10 minutes on and 5 minutes off. Duty cycling cycles electrical loads at regular intervals regardless of need. This reduces the electrical operating costs of building by “fooling” demand indicating devices. Duty cycling of compressors or fans is not recommended since motor winding and bearing life will suffer from constant cycling.

Remote on-off control may be applied by hard-wired connection (see Controls and Troubleshooting literature) or by connection to a Carrier Comfort Network (CCN).
