6. Typical screw chillerTypical oil-free chiller
•Simple
•Fewer connections
•Higher efficiency
•Less maintenance
•Higher reliability Oil free reduces complexity

7. Heat exchanger technology
•Evaporator
–Shell and tube flooded –low
approach temperature. Multiple
compressors. Up to 2 circuits.
–Falling film –reduced
refrigerant charge
–New technology spray plate
exchanger. Very low refrigerant
charge. Single compressor
application suitable for modular
design.

8. Heat exchanger technology
•Condenser
–Shell and tube (water cooled).
Multi compressors. Single or dual
circuit.
–Spray plate (water cooled). Single
circuit, single compressor for
modular chiller design
–Fin and tube (air cooled)
–Micro channel (air cooled)

9. Economiser options
•Plate heat exchanger
•Open flash tank
–Choice between increasing cooling capacity or
increasing efficiency (or mixture of both)
–Most OEMs offer chillers with or without
economiser

Oil free enables multiple compressor
benefit
Multiple oil-free compressors improve energy efficiency at low load
operation

11. Typical chiller EER and ESEER
•Typical EER for air cooled chillers 3.45 to 3.84
•Typical ESEER 5.55 to 5.82
•Available with free cooling option
•Typical EER for water cooled 5.25 to 5.5
•Typical ESEER >8.0

12. Danfoss Turbocor with HFO
refrigerants

13. Danfoss Turbocor with HFO
refrigerants
→
Extremely lightweight and compact
→
Soft startup with low in-rush current
→
Available for 380 – 460 Volt applications
→
Nominal capacity: 230kW, 310 kW,
390kW, and 520 kW
→
Fastest restart time in the industry of
less than 30 seconds without the use of
an external universal power supply.
→
High efficiency at full load and
extraordinarily high efficiency at part
load conditions

14. Summary
•Industry leading part load efficiency
•Low maintenance
•Overall life cycle cost savings compared to
other compressor technologies
•Options for ultra low GWP refrigerants
•Suitable for data centre cooling, commercial
building air conditioning and industrial
applications.
