Water CooledSingle-Screw Chiller

R134a Refrigerant • Daikin’s single screw ZUW.C-B series uses the world most popular “Green” refrigerant, R134a. • R134a refrigerant has a Zero Ozone Depletion Potential• No chlorine in the chemical structure, hence reduce harmful chemical exposed to the atmosphere compared to the conventional refrigerant CFC. • Higher heat transfer efficiency compared to R123, hence, evaporator size can be reduced.• Lower toxicity compared to R123• No phase out time according to Montreal Protocol

High Level Performance, yet Eco-Friendly Efficiency and performance are not the only concerns in a HVAC system today. Environment protection is also a very important consideration to look into. Daikin’s ZUW.C-B series chillers are able to provide precise and good quality cooling for demanding comfort and industrial application without harming the environment. The high performance of Daikin’s ZUW.C-B Chillers is contributed by their well-integrated and well-designed components such as compressor, evaporator, condenser and advanced controllers to produce a high efficiency and energy saving chiller which is certified by AHRI standard.

Zero Clearance Fit• The meshed metal main screw and the non- metal

stars rotors reduced the tolerances and plate shape, results in optimized pressurized oil quantity and eliminates leakage. Hence, the air compression efficiency is improved and increases the overall efficiency of Daikin’s ZUW chiller.

Semi-Hermetic Single-Screw Compressor

Main

Screw

Balanced Force• With opposing and equal suction pressure at both

ends of the screw member, the huge thrust load of twin screw design is eliminated.

• The gate rotors’ balanced radial loading simultaneously compressing on both sides of the rotating screw, nearly eliminates bearing wear and increase the bearing lifespan.

Thrust Loads Radial Loads

Flooded Shell and Tube Evaporator

• Daikin’s ZUW.C-B chillers use a flooded design, shell-and-tube type evaporator. The flooded shell-and-tube evaporator means that the cold liquid refrigerant surrounds the tubes in the shell and cools down the water in the tubes.

• This design allows the refrigerant boils off in the shell and gas can be sucked out from the top of the evaporator back to the compressor. This reduces the suction superheat and increase the capacity performance of the compressor.

Low Maintenance Cost and Convenient Serviceability • Daikin’s ZUW.C-B chillers has a minimal moving

parts which means lesser replacement parts.

• Daikin’s ZUW.C-B chillers adopts a semi-hermetic design compressor which allows easy access to the main screw and gate rotors when the replacement of star bearings or star material if required.

• There are optional suction shut off valves available to provide easier isolation and field service of compressors.

Main ComponentsBuilt-in controller & Touch Screen Panel• Control type: PLC programmable• Operation language: Chinese/English• Screen display: 7 inches touch screen• Operating Environment: -20°C ~ 60°C, Relative: <90%

MicroTech IIIIntelligent Network Controller

Daikin’s ZUW.C-B series adopts the new generation Daikin MicroTech III controller. This programmable controller integrates with the heat pump application and the technologies of Daikin more than 40 years. With this advanced controller, Daikin chiller is able to achieve the highest COP.

Main Functions• Automatic load/unload based on changes of the actual air conditioning load• Operating status display of the unit• Common fault alarm display• Water temperature control to an accuracy of 0.5°C• Output load PID control• Balancing the operating duration of each compressor• Compressor load control• Three-level password protection• Stepless load adjustment• Failure history query• Trends monitoring• Run logs & alarm histories and download

Operating Query Status• Unit status• Temperature of inlet/outlet water• Compressor status• Suction and discharge pressure• Temperature and superheat of suction and discharge• Opening of electrical expansion valve• Oil pressure • Ambient temperature

Protection Functions• High pressure protection• Low pressure protection• High discharge temperature protection• Compressor overload protection• Low compression ratio protection• High oil pressure difference protection
