When two magnetic-bearin compressors were g integrated into a chiller, the sound pressure was 77 dBA at 3.
Seminar On Frictionless Compressor Technology- Mechanical Seminar Topic
They are primarily used for frictiobless, stationary service in industries such as oil refineries, chemical and petrochemical plants and natural gas processing plants. The magnetic bearings normally position the rotor in the ftictionless location, preventing contact between the rotor and other metallic surfaces. Share to Facebook Share to Twitter. Magnetic bearings—two radial and one axial— hold the shaft in position Figure 2.
Reciprocating compressors use pistons driven by a crankshaft. The compressor is key to a new water cooled centrifugal-chiller design, with Air-Conditioning and Refrigeration Institute ARI tests indicating integrated part-load values IPLVs not normally seen with conventional chillers in this tonnage range. Scroll compressors A scroll compressor, also known as scroll pump frictoonless scroll vacuum pump, uses two interleaved spiral-like vanes to pump or compress fluids such as liquids and gases.
In frictionless compressor instead of roller bearings and hydrodynamic bearings, magnetic bearings are used. Sustainable performance assured for compfessor operating life of the chiller. Operations to near zero loads are achievable via an optional, digitally controlled, load balancing valve. It features the same standard suction, discharge and economizer ports as conventional compressors It mounts in the standard way.
Chief among them are increased energy efficiency, the elimination of oil and oil management and considerable less weight, noise, and vibration. Touch screen operator panel is graphically intuitive and easy o use for enhanced operator productivity.
If you need this or any other sample, we can send it to you via email. Seminar Report on Plastic Roads. 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.
Axial-flow compressors Axial-flow compressors are dynamic rotating compressors that use arrays of fan-like aerofoil to progressively compress the working fluid.
Unmatched unloading with the integrated VFDs since the on-board digital control reduce compressor speed to match the load.
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. The use of permanent magnets instead of rotor windings makes the motor smaller and lighter than induction motors. This avoids a gear set.
Frictionless Compressor Published on Jan 10, Easy on energy The ompressor enables chiller and rooftop manufacturers to achieve the necessar product efficiency y levels to meet and exceed ASHRA The design of these compressors is clearly innovative, elegant, and efficient, and all indications are that it is a quality product. With the help of digital control system the controlling and monitoring of work is very easy.
In case of power failure, within 0. Study the seminar report and research paper to understand this emerging technology in mechanical engineering. Low noise and smooth Operation. Conventional bearings can use as much as 10, technolohy, while magnetic bearings re- quire only w. Often, one of 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.
There are no tonal issues, such as those found with some screw compressors, and the noise occurs in the higher octave bands, where technoloogy is easier to attenuate. After 10 years of development, magnetic bearing frictiolness offer economic, energy, and environmental benefits. However, they are relatively technolog, requiring a large number of components, tight tolerances and high quality materials. The convergence of aerospace and industrially proven magnetic bearings, variable-speed centrifugal compression and digital frictionleess technologies enables the frictionless compressors nominal ton capacity range to achieve the highest compressor efficiencies, cost effectively, for middle-market, water-cooled, vaporativecooled and air-cooled HVACR applications.

Current development projects are expanding the range and duty of the compressor wheels and promise to offer even greater efficiencyfor water-coole and air-cooled duties compreswor different capacities. The frictionless compressor technology is compressor with the application of magnetic bearings and permanent magnet synchronous motor. Important status and control information is available at a glance or a touch.
The software has been designed to automatically compensate for any out-of-balance condition in the levitated assembly. Page count 1 page words.
Your email address will not be published. With the help of digital control system the controlling and monitoring of work is very easy. Such a motor has a significant efficiency increase over an induction motor, especially at low motor speeds, as shown in the figure above.
Most DX systems allow oil to travel through the refrigeration circuit and back to the compressor oil sump. Frictionless Compressor Technology is one of the fast growing Technology in the engineering field. A rotary vane compressor is well suited to electric motor drive and is significantly quieter in operation than the equivalent piston compressor.
By using the smaller shaft, they are able to take advantage of thecentrifugal compressor technology in a smaller size than is normally available.
The program compared an hourly analysis of a ton frictionless chillers with that of a water cooled reciprocating chiller Phoenix, Chicago and Tampa and a water cooled centrifugal chiller New York.
