Frictionless Compressor | Seminar Report, PPT, PDF for Mechanical | Amrit Sahoo –

Scroll compressors A scroll compressor, also known as scroll pump and scroll vacuum pump, uses two interleaved spiral-like vanes to pump or compress fluids such as liquids and gases.

The positive pressure, oil-free design eliminates performance degradation due to non-condensable and oil contamination of the refrigerant.

The frictionless compressor technology is compressor with the application of magnetic bearings and permanent magnet synchronous motor.

No COP deterioration with time. Centrifugal compressors tend to be more efficient than screw or scroll Compressors, and take advantage of speed control more effectively, but they are usually only availablein larger sizes. Plans call for that range to be extended to tons water-coole and tons air-cooled by the end d of with the use of Ra refrigerant.

A rotary vane compressor is well suited to electric motor drive and is significantly quieter in operation than the equivalent piston compressor. Magnetic-bearing technology is significantly different. Inside, the compressor is totally self-correcting and incorporates a system of sophisticated self-diagnosticsmonitoring and control. After 10 years of development, magnetic bearing compressors offer economic, energy, and environmental benefits.

Frictionless Compressor Technology Essay

Types of compressors The main types of gas compressors are illustrated and discussed below: The frictionless compressor technology is compressor with the application of magnetic bearings and permanent magnet synchronous motor. Then mail to us immediately to get the full report. Problem with Traditional Technology 1. Reduced maintenance costs due to elimination of oil.

Complete service agreements and extended maintenance contracts can be provided by the manufacturer. The software has been designed to automatically compensate for any out-of-balance condition in the levitated assembly.

The magnetic bearings normally position the rotor in the proper location, preventing contact between the rotor and other metallic surfaces. Zero Energy Building Project Report.

Diaphragm compressors are used for hydrogen and compressed natural gas CNG as well as in a number of other applications. These copper windings are bulky, adding size and weight to the compressor.

A digitally controlled magnetic-bearing system, consisting of both permanent magnets and electromagnets, replaces conventional lubricated bearings. The software has been designed to automatically compensate for any out-of-balance condition in the levitated assembly. Touch screen operator panel is graphically intuitive and easy o use for enhanced operator productivity.

The motor and key electronic components are internally refrigerant cooled, so no specialcooling is required for the VFD or the motor. Easy fridtionless with our open choices feature using BACnet, LonWorks or Modbus communications without an expensive panel. F r i c t i o n- l e s s Te c h ngyo lo Compressor A new compressor technology introduced during the International Air-Conditioning, Heating, Comrpessor Exposition AHR Expoheld l January in Chicago, may have a significant effect on the future of mid-range chillers and rooftop applications in watercooled, evaporative cooled, and air-cooled chilled water and direct-expansion DX systems.

If you need this or any other sample, we can send it to you via email. Frictionless compressors make new revolutions in air-conditioning, refrigeration.

Frictionless oil-free using magnetic bearings. The capacitors, in turn, provide enough power to maintain levitation during coast down; allowing the motor rotor to swminar and DE levitate. Frictionless Compressor Technology is one of the fast growing Technology in the engineering field.

It can use the same power wiring with a single control.

A ccording A R I testing,a tonfrictionless to chiller has a full-loadperform ance 0. A digitally controlled magnetic-bearing system, consisting of both frictioonless magnets and electromagnets, replaces conventional lubricated bearings.

Often, one comprewsor the scrolls is fixed, while the other orbits eccentrically without rotating, thereby trapping and pumping or compressing pockets of fluid or gas between the scrolls. A higher number of revolutions per minute can be obtained by sminar the frequency.

This compressor has high reliability, efficiency, less maintenance cost and staff. If the magnetic bearings fail, the touchdown bearings also known as backup bearings are used to prevent a compressor failure. This can be overcome by the introduction of new compressor technology called frictionless compressor technology.

Two-pole, Hz induction motors operate at approximately 3, rpm.

Finally I would like to thank the almighty for his blessings without which this work could not have been accomplished.
