Copeland Oil-free Centrifugal Compressor with Aero-lift Bearing Technology
Category: Mechanical/Materials
Developers: Southwest Research Institute
Product Description:The Copeland Oil-free Centrifugal Compressor with Aero-lift Bearing Technology offers a system which eliminates expensive magnetic bearings and complicated bearing control technology. The system has robust cooling capacity, energy efficiency, flexible architecture and performance-enhancing algorithms. The Copeland Oil-free Centrifugal Compressor with Aero-lift Bearing Technology delivers improvements across key chiller performance metrics. This system has been proven to achieve up to a 10% increase in full-load efficiency versus other compression technologies in air-cooled applications. It also delivers up to a 40% efficiency increase in integrated part-load value — far exceeding the ASHRAE 90.1 efficiency minimum requirements for a two-compressor, 200-ton system, versus existing screw compressor technology. This efficiency is made possible by integrating critical components, including Aero-lift bearing technology and numerous granted patents and patent-pending innovations on the compressor and the control system. The Copeland Oil-free Centrifugal Compressor with Aero-lift Bearing Technology uses a compressor platform optimized to meet today’s chiller requirement needs while providing broad applicability for current and emerging applications. The Aero-lift bearing technology enables the compressor shaft to self-levitate and operate independently, eliminating traditional magnetic levitation or oil-bearing ancillary systems. The system is designed to provide performance improvements during power interruptions with its capability to shut down and restart rapidly to minimize disruptions.
