Development Environment Technology 2 Daikin s pre-eminent position in air conditioning and chiller production has been built on over 70 years experience. It is also the result of an intensive and ongoing programme of research and development. Only thus can the high quality, optimised products, which have become the hallmark of Daikin, be brought to the market. The EUWA*-K(A)X are available in several capacities over a wide operation range. These chillers are produced in Ostend, Belgium and distributed via an extensive network of highly experienced specialists. The careful development of closely matched compressor/refrigerant combinations, has enabled Daikin to produce complete ranges of water chillers genuinely optimised for use with ozone friendly R-134a refrigerants that possess the same quality and performance levels as our renowned R-22 models. Daikin chillers offer the ultimate in flexibility and control a reflection of 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 an indoor environment that is comfortable, clean and consistent.

Daikin F-type single screw compressor Optimised for R-134a Low sound level High energy efficiency ratio Electronic control Compact dimensions Wide operation range Anti-corrosion treated heat exchangers Control systems: DDC control, BMS, DICN 3

OPTIMISED FOR R-134a All components compressor, evaporator, condenser, dryer, oil etc. have been specially selected by Daikin for use with R-134a refrigerant, making Daikin one of the only manufacturers of R-134a optimised chillers. Piping sizes and diameters have also been modified to ensure complete compatibility. LOW SOUND LEVELS The use of specially designed components such as propellers, single screw compressor, etc. enables Daikin R-134a chillers to achieve low operating sound levels. For special applications, a low sound version is available. HIGH ENERGY EFFICIENCY RATIO Large Daikin R-134a air cooled water chillers are of the most energy efficient chiller units on the market. OPERATION RANGE The Daikin air cooled chillers with R-134a are ideal for use in severe weather conditions within 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 with an exceptionally wide range of leaving water temperatures (down to 4 C (standard) or 10 C (glycol)) which makes them suitable for use in comfort cooling as well as process cooling applications from plastic factories to wine cooling and storage areas. ambient temperature C 50 43 40 39 33 30 20 10 0-10 -15-20 * ZL ZH Continuous operation area ** Pulldown area * Glycol (optional) ** Water (standard) -30-5 4 16 26-20 -10 0 10 20 30 leaving evaporator water temperature ( C) 4 Protect the water circuit against freezing by: or heater tape (optional) or filling up the system with a glycol solution

Daikin F-type semi hermetic single screw compressor. All chillers in the range are fitted with a new Daikin semi hermetic screw compressor, purpose designed to operate with R-134a refrigerant, guaranteeing many years of reliable and efficient operation. Terminal plate Refrigerant suction Motor Refrigerant discharge Newly designed compact oil recovery system for easier maintenance and servicing Durable polymer gate rotors guarantee long life and optimum performance 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. Slide valve for reliable capacity control BENEFIT: unequalled reliability for increased long life operation overhaul only necessary after 40,000 hours running (= 4.5 years of continuous operation) 5

VICTAULIC JOINTS The air cooled chillers are standard fitted with victaulic joints on evaporator and condenser pipes. Victaulic joints absorb vibrations, reduce operating sound and thermal deflection and simplify chiller piping and installation. They can accommodate 8 angles and guarantee stress free, leak tight water piping connection. CHILLER AND COMPRESSOR SAFETY Daikin 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 EXCHANGERS Condenser 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 as standard against effects from severe weather conditions large chillers are fitted with chromate coated waffle louvre fins. Moreover, condenser protection grilles are available throughout the whole range (see page 9). REFRIGERANT CIRCUIT The refrigerant circuit is equipped as standard with discharge stop valve, sight glass with moisture indicator, thermal expansion valve with maximum operating pressure, solenoid valve and filter dryer with charging valve. A service port is provided on the insulated suction pipe and on the liquid dryer. 6

DDC (DIGITAL DISPLAY CONTROL) The air-cooled chillers are equipped with a DDC control (digital display control). This auto adaptive control system provides detailed information on and accurate control of all functional parameters 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 contacts for remote start/stop and double set point switch. The control is standard equipped for night setback and peak load limitation. The DDC control is removable once programmed, the chiller can run without 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 building management 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 chiller and 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. 7

DICN (DAIKIN INTEGRATED CHILLER NETWORK) Daikin chillers with DDC can be equipped with DICN which allows the simultaneous operation of up to 4 chillers as if they were a single unit, in order to deliver the required cooling capacity. This results in precise and efficient capacity control and is also useful for back up purposes, ensuring that the necessary amount of cooling is available and guaranteeing reliable operation of the chiller plant. This function enables a Daikin 2MW chiller plant 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 8
