Features/Benefits (cont)

Easy installation

The AquaForce® 30XW screw chillers are shipped with starter and unit mounted flow switch installed and can be shipped with a full R-134a refrigerant charge to minimize installation time. The unit provides single point power connection (using optional control power transformer) and quick, easy piping connections (using Victaulictype clamp on couplings). The 30XW 200-v, 230-v, 460-v, and 575-v units are designed in accordance with UL (Underwriters Laboratory) and UL Canada (Underwriters Laboratory, Canada) standards to minimize electrical inspection time.

Dual circuits

Dual independent refrigerant circuits provide reliable, dependable cooling, excellent part load operation, and redundancy. Each circuit includes its own compressor, electronic expansion valve, filter drier, and sight glass to assure operation.

High efficiency

The Aquaforce 30XW screw chiller efficiency levels meet or exceed energy efficiency requirements of ASHRAE (American Society of Heating, Ventilation and Air Conditioning Engineers)

90.1 2007 and CSA (Canadian Standards Association) for both full load and part load operation and is certified to AHRI standards.

Per AHRI 550/590, chillers operate at design conditions less than one percent of the time. As a result, superior part load efficiency is required for today's chilled water applications. The 30XW chillers deliver integrated part-load

values (IPLV) as low as 0.468 kW per ton at AHRI conditions while offering the ability to operate in a broad range of applications and climates. This exceptional performance has a significant impact on energy savings and cost of ownership.

Heat recovery

The Aquaforce 30XW screw chiller provides up to 140 F (60 C) leaving condenser water (requires 300 psig [2068 kPa] condenser option) when applied in heat recovery applications. Further, the 30XW unit heat control mode can be utilized to maintain a constant leaving condenser water temperature. Low source controls provide evaporator suction protection to prevent nuisance trips when operating in heat recovery applications. This flexible capability allows a chiller to meet both cooling and heating requirements providing a high level of interchangeability within a chilled water plant.

Environmental leadership

Carrier has long been committed to the environment and its sustainability. The Aquaforce 30XW screw chiller provides customers with a high-efficiency, chlorine free, long-term solution unaffected by refrigerant phase outs. Carrier's decision to utilize non-ozone depleting R-134a refrigerant provides customers with a safe and environmentally sound choice without compromising efficiency. In addition, R-134a refrigerant was given an A1 safety rating by ASHRAE, meaning that it is among the safest refrigerants available.

Positive displacement screw compression

Positive displacement compression ensures stable operation under all load conditions without the possibility of compressor surge. High-efficiency rotary twin screw compressors with infinitely variable slide valves allow the chillers to exactly match actual load conditions, delivering excellent part load performance.

Factory testing

A quick start-up is assured once installation is complete, since each 30XW unit is manufactured at an ISO (International Organization for Standardization) 9001:2000 listed manufacturing facility to ensure quality. In addition, all 30XW units that are shipped with a full charge of R-134a refrigerant are tested under load at the factory to provide reliable start-up.

Low starting current (inrush)

Dual circuit units stage the start up of the compressors thereby reducing the over all current draw by up to 40%.

Constant or variable evaporator flow

Aquaforce 30XW screw chillers are suitable for constant or variable evaporator flow.

Hermetic motor

The Aquaforce 30XW chiller utilizes motors that are hermetically sealed from the machine room. Refrigerant is used to cool the motor windings.

Carrier's hermetic design eliminates:

• Compressor shaft seals that require maintenance and increase the likelihood of refrigerant leaks.

• Machine room cooling requirements associated with air-cooled motors, which dissipate heat to the mechanical room.

• High noise levels common with aircooled motors, which radiate noise to the machine room and adjacent areas.

• Shaft alignment problems that occur with open-drive designs during startup and operation, when equipment temperature variations cause thermal expansion.

Positive pressure design

Positive pressure designs eliminate the need for costly low pressure containment devices, reducing the initial cost

of the system. The AquaForce® 30XW chiller's positive pressure design ensures that air, moisture and other performance degrading contaminants are not sucked inside the chiller. Purge units and their associated maintenance are no longer necessary.

Refrigerant isolation valves

The refrigerant isolation valves enable service personnel to store the refrigerant charge in the evaporator or condenser during servicing. These valves also allow the refrigerant to be stored inside the chiller during shipment from the factory minimizing start-up time. During servicing, the in-chiller storage reduces refrigerant loss and eliminates time-consuming transfer procedures. As a self-contained unit, the AquaForce 30XW chiller does not require additional remote storage systems.

Optional suction service valves

The optional suction service valves allow for further isolation of the compressor from the evaporator vessel.

Marine container shipment

The compact design allows for container shipment to export destinations, ensuring quality while reducing shipping cost.

Heat exchangers

The Aquaforce 30XW chillers utilize mechanically cleanable shell and tube evaporators and condensers available with a complete line of waterbox options to meet project specific requirements. One, two, and three pass arrangements are available to meet a wide variety of flow conditions. Nozzle in head and marine waterboxes are available to meet 150 psig (1034 kPa) and 300 psig (2068 kPa) piping requirements.

Heat exchanger features include:

ASME certified construction

An independent agency certifies the design, manufacture, and testing of all heat exchangers to American Society of Mechanical Engineers (ASME) standards, ensuring heat exchanger safety, reliability and long life. The ASME U-stamp is applied to the refrigerant side of the evaporator and condenser and is applied to the water side of these heat exchangers when 300 psig (2068 kPa) marine waterboxes are provided.

Electronic thermal-dispersion flow switch

An electronic thermal-dispersion flow switch switch is included with the evaporator. The switch is factory installed and tested and contains no moving parts for high reliability.

High performance tubing

Carrier's AquaForce chillers utilize advances in heat transfer technology providing compact, high-efficiency heat exchangers. Tubing with advanced internally and externally enhanced geometry improves chiller performance by reducing overall resistance to heat transfer while reducing fouling.

Evaporator tube expansion

Evaporator tube expansion at center support sheets prevents unwanted tube movement and vibration, thereby reducing the possibility of premature tube failure. Tube wall thickness is greater at the expansion location, support sheets, and end tube sheets, to provide maximum strength and long tube life.

Closely spaced intermediate support sheets

Support sheets prevent tube sagging and vibration, thereby increasing heat exchanger life.

Refrigerant filter isolation valves

These valves allow filter replacement without pumping down the chiller, reducing service time and expense.

Microprocessor controls

The AquaForce 30XW screw chiller controls communicate in easy to understand English, making it as easy as possible to monitor and control each chiller while maintaining fluid temperatures. Controls are available with French, Portuguese and Spanish as standard configuration options. These controls result in higher chiller reliability, simplified training and correspondingly lower operational and maintenance costs.

Two user interface options are available, the Touch Pilot™ display and the Navigator™ module.

The Touch Pilot display is an easy to use touch screen display that provides simple navigation for configuration and control of the 30XW units.

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 30XW units are ready to be used with Carrier Comfort Network devices.

Controls features include:

Automatic capacity override

This function unloads the compressor whenever key safety limits are approached, increasing unit life.

Chilled liquid reset

Reset can be accomplished manually or automatically from the building management system. For a given capacity, reset allows operation at slower compressor speeds, saving energy when warmer chilled liquid can be used.

Demand limiting

This feature limits the power draw of the chiller during peak loading conditions. When incorporated into the CCN building automation system, a red line command holds chillers at their present capacity and prevents any other chillers from starting. If a load shed signal is received, the compressors are unloaded to avoid demand charges whenever possible.

Ramp loading

Ramp loading ensures smooth pulldown of liquid loop temperature and prevents a rapid increase in compressor power consumption during the pulldown period.

Automated controls test

The test can be executed prior to startup to verify that the entire control system is functioning properly.

365-day real time clock

This feature allows the operator to program a yearly schedule for each week, weekends, and holidays.

Occupancy schedules

Schedules can be programmed into the controller to ensure that the chiller operates when cooling is required and remains off when not needed by the tenants or process.

ACCESSORY

Factory-installed options

Navigator™ module provides a portable, hand-held dis-

play for convenient access to unit status, operation, configuration and troubleshooting diagnostics capability. The four-line, 20-character LCD (liquid crystal display) display provides clear language information in English, French, Spanish, or Portuguese. The Navigator module features an industrial grade extension chord and magnets located on the back of the weatherproof enclosure to allow attachment to sheet metal components for hands free operation.

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

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

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-point demand limit control (from 0 to 100%) activated by a remote contact closure, and discrete input for "Ice Done" indication for ice stage system interface.

The 300 psig (2068 kPa) evaporator operating pressure option allows operation for water-side pressure

up to 300 psig (2068 kPa).

The 300 psig (2068 kPa) condenser operating pressure option allows operation for water-side pressure

up to 300 psig (2068 kPa). Minimum load control allows additional capacity reduc-

tion for unit operation below the minimum step of unloading via hot gas bypass.

Marine waterboxes provide water piping connections extending from the side of the waterbox (as opposed to extending from the end of the waterbox). This option also includes a removable bolt on waterbox cover allowing access to the heat exchanger tubes without breaking the existing field piping. This option is available for both the evaporator and condenser.

One-pass evaporator provides a lower pressure drop through the evaporator for applications with low delta T (temperature) or high flow or where the evaporators are piped in a series or side stream arrangement. One-pass evaporator is only available with flanged connections and with discharge end leaving water connection.

Three-pass evaporator provides a greater efficiency for brine applications and in applications with a high delta T and low flow. Three-pass evaporator is only available with flanged connections.

Heat machine condenser allows operation with up to 140 F (60 C) leaving condenser water temperature (see E-CAT for selections). In addition, this option provides factory-installed thermal insulation on the condenser, condenser flow switch and leaving condenser water

temperature sensor to facilitate operating in HEAT mode. Heat machine units require 300 psig (2068 kPa) option and field-installed thermal insulation on the compressor discharge piping and waterbox heads because of high temperature.

One-pass condenser provides a lower pressure drop through the condenser for applications with low delta T (temperature) or high flow or where the condensers are piped in a series. The one-pass condenser option is only available with flanged connections and with a discharge end leaving water connection.

Wye-delta start is an alternate starting method which reduces the inrush current when starting the compressor. Wye delta start is standard on 208-v, and 230-v units, optional for 380-v, 460-v, and 575-v.

Dual point power provides a means for connecting two sources of power to dual compressor 30XW chillers. One source of power is wired to operate the compressor on the A circuit and one source of power is wired to operate the compressor on the B circuit of the chiller.

Non-fused disconnect provides a no load, lockable, through the door handle disconnect for unit power on the chiller. On dual point power, one disconnect is provided for each of the two main power supplies. This disconnect does not remove the control circuit from power supply.

Control transformer is sized to supply the needs of the control circuit from the main power supply.

115-v GFCI convenience outlet includes 4 amp GFI (ground fault interrupt) receptacle. Convenience outlet is 115-v female receptacle. Not available with 380-v units.

Nitrogen charge provides a 15 lb (6.8 kg) charge of nitrogen instead of a full factory charge of R-134a refrigerant to keep the chiller refrigerant circuit dry during shipment. This option is recommended for applications where the unit will be disassembled prior to installation. Units shipped with a nitrogen charge will receive an electrical continuity test at the factory prior to shipment.

Crate for shipment provides a wooden crate around the chiller. The chiller is bagged prior to being placed in the crate. This option is recommended for export orders.

Suction service valves allow for further isolation of the compressor from the evaporator vessel.

Field-installed accessories

Remote enhanced display is a remotely mounted

indoor 40-character per line, 16-line display panel for unit monitoring and diagnostics.

Temperature reset sensor provides temperature reset capability from either the occupied space or outdoor temperature sensor.

NOTE: Temperature reset capability using return temperature is standard.

Vibration isolation pads are neoprene pads for installation under the chiller feet at the jobsite.

Vibration springs provide a set of non-siesmic spring isolators for installation at the jobsite.

Navigator™ module provides a portable, hand-held display for convenient access to unit status, operation, configuration and troubleshooting diagnostics capability.
