Environment

DevelopmentDaikin’s pre-eminent position in air conditioning and chiller productionhas been built on over 70 years’ experience. It is also the result of anintensive and ongoing programme of research and development .Only thus can the high quality, optimised products, which have becomethe hallmark of Daikin, be brought to the market.

The EUWA*-K(A)X are available in several capacities over a wideoperation range. These chillers are produced in Ostend, Belgium anddistributed via an extensive network of highly experienced specialists.

The careful development of closely matched compressor/refrigerantcombinations, has enabled Daikin to produce complete ranges ofwater chillers – genuinely optimised for use with ozone friendly R-134arefrigerants – that possess the same quality and performance levels asour renowned R-22 models.

Daikin chillers offer the ultimate in flexibility and control — a reflectionof the advanced technology inherent within them. Unique in their precision, power, low operating noise, easy maintenance and low running costs, Daikin chillers represent the sure and safe route to anindoor environment that is comfortable, clean and consistent.

OPTIMISED FOR R-134aAll components – compressor, evaporator, condenser, dryer, oil etc. have been specially selectedby Daikin for use with R-134a refrigerant, making Daikin one of the only manufacturers ofR-134a optimised chillers. Piping sizes and diameters have also been modified to ensurecomplete compatibility.

LOW SOUND LEVELSThe use of specially designed components such as propellers, single screw compressor, etc.enables Daikin R-134a chillers to achieve low operating sound levels. For specialapplications, a “low sound” version is available.

HIGH ENERGY EFFICIENCY RATIOLarge Daikin R-134a air cooled water chillers are of the most energy efficient chiller units onthe market.

OPERATION RANGEThe Daikin air cooled chillers with R-134a are ideal for use in severe weather conditionswithin the -15°C to 43°C ambient temperature range. This major benefit results from the incorporation of an auto adaptive control system with built-in functions that include:• head pressure control: fan control for low ambient operation down to -15°C• head pressure setback for high ambient operation:

on hot days, when cooling is most needed, some chillers tend to trip out on high pressure protection. Daikin chillers will stay on line and prevent this situation by adjusting the capacity control.EUWA*-K(A)X series chillers can be operated withan exceptionally wide range of leaving watertemperatures (down to 4°C (standard) or –10°C(glycol)) which makes them suitable for use incomfort cooling as well as process coolingapplications from plastic factories to wine coolingand storage areas.

FEATURES:• compact, simple and robust construction• lack of valves or critical reciprocating components increases resistance to liquid slugging

and ensures maximum reliability• very low bearing load, well-balanced axial and radial forces by symmetrical compression

with a single rotor and 2 idle turning gate rotors• very low vibration levels, resulting in less wear and low operating sound level

(silencer incorporated within compressor)• durable polymer gate rotors eliminate friction and significantly reduce wear and energy

losses• no oil pump necessary: lubrication is done according to the pressure difference principle• compressor is cooled and sealed by liquid refrigeration injection, resulting in a constant working

temperature throughout an extended working life and allowing reduced rotor clearance for accurate and efficient compression

ADDITIONAL FEATURES:• standard discharge stop valve• easy access to both compressor and safety devices• star delta starter with low starting current as standard.

BENEFIT:unequalled reliability for increased long life operation overhaul only necessary after 40,000hours running (= 4.5 years of continuous operation)

VICTAULIC JOINTSThe air cooled chillers are standard fitted with victaulic joints on evaporator and condenser pipes. Victaulic joints absorb vibrations, reduce operating soundand thermal deflection and simplify chiller piping and installation. They can accommodate 8° angles and guarantee stress free, leak tightwater piping connection.

CHILLER AND COMPRESSOR SAFETYDaikin chillers are equipped with functions to ensure safe and reliable operation under all loads and in all applications.

On the EUWA*-K(A)X units these include:• double TüV approved high pressure

switches• low pressure protection• double freeze up protection• compressor safety• compressor motor thermal protection• compressor motor over current relay• reverse phase protector

• pressure relief valve on compressor• discharge temperature controller• anti recycling and guard timers• liquid and discharge stop valve• service port on insulated suction pipe

and liquid dryer• standard evaporator heater tape for anti

freeze up protection on Tüv-model• DDC controller

HEAT EXCHANGERSCondenser coils are constructed from especially designed header distribution pipes, in combination with internally grooved Hi-X tubing and aluminium waffle louvre pressed fins.This unique combination of increased contact surfaces and reduced overall coil size, results in optimum heat transfer efficiency. All condenser coils are anti corrosion treated asstandard against effects from severe weather conditions – large chillers are fitted with chromate coated waffle louvre fins. Moreover, condenser protection grilles are availablethroughout the whole range (see page 9).

REFRIGERANT CIRCUITThe refrigerant circuit is equipped as standard with discharge stop valve, sight glass withmoisture indicator, thermal expansion valve with maximum operating pressure, solenoid valveand filter dryer with charging valve. A service port is provided on the insulated suction pipeand on the liquid dryer.

DDC (DIGITAL DISPLAY CONTROL)

The air-cooled chillers are equipped with a DDC control (digitaldisplay control). This auto adaptive control system providesdetailed information on and accurate control of all functionalparameters by easy menu screen scrolling.

The DDC control is self diagnostic and can be set up in several languages (English, French, German, Spanish, Italian).Lead lag function is standard, as well as voltage free contactsfor remote start/stop and double set point switch. The control isstandard equipped for night setback and peak load limitation.The DDC control is removable – once programmed, the chiller can runwithout remote control or with the control located up to 1,000 meters from the unit !

BMS CONNECTION KIT (BUILDING MANAGEMENT SYSTEM)

Any Daikin chiller with a DDC control can be equipped with a connection to a buildingmanagement system. This system monitors and controls lighting, alarms, ventilation – and also Daikin chillers. The Daikin BMS connection supports popular standard protocols such as MODBUS, J-BUS and BACNET and consists of built in address cards for each chillerand a single gateway that can link as many as 16 chillers to the BMS.The BMS supports the complete operation of the chiller and can also monitor and control more than 130 individual parameters including the monitoring of chiller settings, status, temperatures, pressures, alarms and the control of setpoints and on/off operation.

DICN (DAIKIN INTEGRATED CHILLER NETWORK)Daikin chillers with DDC can be equipped with DICNwhich allows the simultaneous operation of up to 4chillers as if they were a single unit, in order to deliverthe required cooling capacity. This results in precise andefficient capacity control and is also useful for back uppurposes, ensuring that the necessary amount of coolingis available and guaranteeing reliable operation of thechiller plant. This function enables a Daikin 2MW chillerplant to be operated via a single controller.

ADVANTAGES:• choice between common leaving or entering water control• intelligent temperature control• energy saving and increasing the lifetime of the pumps• a difference in running hours between the different units can be programmed• night setback function• peak load limitation• the DICN grouped units can be integrated in the BMS• the controller can be located up to 300 m from the unit• voltage free contacts are available
