Air-Cooled Screw Compressor Liquid ChillersHigh-efficiency, high outdoor temperature version

GLOBAL CHILLER

The 30GX units are air-cooled chillers, designed from the ground up to meet the needs of today and tomorrow:- ecological HFC-134a refrigerant- screw compressors- compact footprint- mechanically cleanable evaporatorAll units are equipped with PRO-DIALOG Plus control to optmize the efficiency of the refrigerant circuit, and with the revolutionary FLYING BIRD fan with rotating shroud. This innovative fan considerably reduces the air circulation noise and contributes to quiet unit operation. It is made of fully recyclable composite materials.The high outdoor temperature versions are equipped with condensers with non-slatted double-wavy fins to reduce the fouling effect (sand, dust etc.), and with ventilated control boxes to keep the electrical components at the right tempe-rature.

FeaturesQuality design and construction make the 30GX unit the preferred choice.

■ Non-controlled, ozone-friendly HFC-134a refrigerant. HCF-134a is a proven, non-toxic, non-flammable refriger-ant which will have the highest usage of any new refriger-ant.

■ Medium-pressure refrigerant HFC-134a minimizes stress on the compressors and ensures their long operating life.

■ The 30GX units are equipped with screw compressors and with shrouded axial Flying Bird fans for extremely quiet operation and low-vibration levels.

■ The 30GX units exceed the efficiency level of average industry standards for both full- and part-load operation, saving on operating costs, through lower electrical costs.

■ The 30GX control is fully automatic. The leaving water temperature is continuously monitored to detect load and flow changes. This combination provides the most precise temperature control available.

■ Two independent refrigerant circuits - the second one takes over automatically, when the first one malfunctions, main-taining partial cooling under all circumstances.

■ Easy installation - the 30GX chillers are supplied with a full refrigerant charge, and conveniently located power supply and water inlet and outlet connections.

■ Auto-diagnostics - quick display of the machine status.■ Multiple compressor concept for optimized part-load effi-

ciency and minimized starting current.■ Series star/delta starter, limiting the start-up current on

30GX 082-182 units.

Easy installation■ The 30GX has a compact design that is up to 50% smaller

than current chillers. The 30GX is supplied as a complete package for easy installation. There are no extra controls, timers, starters or other items to install.

■ 30GX units have a single power point and one main discon-nect/isolator switch for sizes 30GX 082 to 182, and one power point and one main disconnect/isolator switch per circuit for sizes 30GX 207 to 358.The hydraulic connections are simple and facilitated by the use of Victaulic connections for the evaporator.

Simple to service■ Mechanically-cleanable evaporator■ Twin-screw compressors which require minimum routine

service or maintenance.■ Easily accessed suction and discharge pressure and tempe-

rature information via a display module.

PRO-DIALOG Plus controlPRO-DIALOG Plus is an advanced numeric control system that combines intelligence with great operating simplicity.

PRO-DIALOG Plus ensures intelligent leaving water temperature control and optimises energy require-ments.■ The PID control algorithm with permanent compensation

for the difference between the heat exchanger entering and leaving temperature, anticipates load variations, guarantees leaving water temperature stability and prevents unneces-sary compressor cycling.

■ The long-stroke electronic expansion valves (EXV), together with refrigerant level control via heat exchange in the evaporator, allows a significant energy efficiency improvement at part load conditions, and faultless chiller operation in a wider temperature range.

■ Adjustable ramp loading, according to the inertia of the application, avoids load increases that are too fast and too frequent, increasing unit life and limiting power consump-tion peaks.

■ Several capacity loading possibilities ensure improved start-up at low outdoor air temperature, and permit use of one of the refrigerant circuits as a back-up circuit.

PRO-DIALOG Plus ensures preventive protection and enhances chiller reliability.■ Equalisation of compressor operating hours■ No capillary tubes or pressostats (except as safety device)■ PRO-DIALOG Plus monitors all chiller safety parameters.

The fault history function and the fault codes facilitate immediate location of faults and in certain cases the condi-tions causing the alarm. Prognostic and preventive mainte-nance functions (incorrect water loop, oil filter dirty etc.) permit anticipation of possible problems.

PRO-DIALOG Plus offers extended communications capabilities■ Clear and easy-to-understand operator interface. The LEDs,

numeric displays and touch keys are well-positioned on the schematic chiller diagram. The user immediately knows all operating parameters: pressures, temperatures, operating hours, etc.

■ The extensive chiller remote control capabilities (wired connection) allow integration into building monitoring sys-tems (see Technical Description)

■ RS485 series port for connection to the Carrier Comfort Network (CCN) or any other monitoring system (accessory communications interface with open protocol allows trans-fer of almost 40 parameters).

■ Parallel piloting of two units as standard, or of several units with Flotronic System Manager (FSM) and Chiller System Manager (CSM III) options.

■ The control permits:- Control in master/slave configuration of two units operat-

ing in parallel.- Programming of operating time schedules (up to 8 peri-

ods per week)- Programming of operating time schedules for the second

set point (up to 8 periods per week)- Definition of operating time period with demand limit.- Integration of the unit into a building monitoring system

(BMS): serial port RS 485.■ Control of the customer’s water pump (dual pump with

automatic configurable change-over).■ Control at the second set point (example: room unoccu-

pied).Set point reset as a function of the air temperature or the difference between entering and leaving water temperature.
