frictionless compressor technology seminar report

Abstract
Magnetic bearing centrifugal compressor eliminates the efficiency-robbing friction inherent in traditional centrifugal chiller. Integrated VFD optimized part load efficiency, a key performance feature since most chillers operate at part load 99% of their life. Sustainable performance assured for the operating life of the chiller.

The positive pressure, oil-free design eliminates performance degradation due to non-condensable and oil contamination of the refrigerant. Easy integration with our open choices feature using BACnet, LonWorks or Modbus communications without an expensive panel.R-134a refrigerant has no depletion potential and no phase=out schedule. Reduced maintenance costs due to elimination of oil.

Oil system, purge system, and shaft seals found in order technology chillers. Small unit footprint helps the magnitude chiller fit in place where space is limited, making it ideal for retrofit projects. Unmatched unloading with the integrated VFDs since the on-board digital control reduce compressor speed to match the load. Low inrush current at start-up is ideal for operation with backup or emergency power systems. Touch screen operator panel is graphically intuitive and easy o use for enhanced operator productivity. Important status and control information is available at a glance or a touch.

Introduction:
Traditional centrifugal compressors use roller bearings and hydrodynamic bearings, both of which consume power and require oil and lubrication system. This can be overcome by the introduction of new compressor technology called frictionless compressor technology.

The frictionless compressor technology is compressor with the application of magnetic bearings and permanent magnet synchronous motor. In frictionless compressor instead of roller bearings and hydrodynamic bearings, magnetic bearings are used. Magnetic bearings consume less power and there is no need for oil and lubrication systems. Permanent magnet brushless synchronous motor has permanent magnet instead of copper windings.

After 10 years of development, magnetic bearing compressors offer economic, energy, and environmental benefits. Chief among them are increased energy efficiency, the elimination of oil and oil management and considerable less weight, noise, and vibration. This is initial mid-range package offers centrifugal compression efficiencies previously reserved for large tonnage systems only.

This compressor has high reliability, efficiency, less maintenance cost and staff. With the help of digital control system the controlling and monitoring of work is very easy. The frictionless compressor technology makes newrevolutions in the field of air conditioning, refrigeration etc. Frictionless Compressor Technology is one of the fast growing Technology in the engineering field.

The Frictionless compressor is also the world’s first totally Oil-Free compressor specifically designed for the Heating, Ventilation, Air Conditioning and Refrigeration (HVACR) industry. The variable-speed centrifugal compression and digital electronic technologies enables the frictionless compressors (nominal 60-150 ton capacity range) to achieve the highest compressor efficiencies, cost effectively, for middle-market, water-cooled, evaporative cooled and air-cooled HVACR applications. The well-proven energy performance advantages of variable-speed centrifugal

Compressors are now brought to mainstream middle-market applications through the use of High-speed, two-stage centrifugal compression with integral variable-speed drive. Compressor speed is reduced as the condensing temperature and/or heat load reduces, Optimizing energy performance through the entire operating range from 100% to 20% or below of rated capacity.

Operations to near zero loads are achievable via an optional, digitally controlled, load balancing valve. Centrifugal compressors tend to be more efficient than screw or scroll Compressors, and take advantage of speed control more effectively, but they are usually onlyavailablein largersizes. By using the smaller shaft, they are able to take advantage of thecentrifugal compressor technology in a smaller size than is normally available.
