Energy-Efficient Cooling Technologies

摘要

Two developments in energy-efficient central chilling will be shown by Frigel North America, E. Dundee, Ill. One will be the brand-new Ecoflex chiller (photo) with variable-speed centrifugal compressor and oil-free magnetic bearings. This unique Danfoss Turbocor compressor technology has been adopted by other chiller makers because it offers substantial energy savings (depending on load), space-saving compactness, unusual quietness, and low maintenance.
