The variable-speed centrifugal compression and digital electronic technologies enables the frictionless compressors nominal ton capacity range to achieve the highest compressor efficiencies, cost effectively, for middle-market, water-cooled, evaporative cooled and air-cooled HVACR applications.
Home chillers compressor energy saving magnetic bearing Mechanical oil less pdf seminar report Energy Saving: How About Make It Original? In frictionless compressor instead of roller bearings and hydrodynamic bearings, magnetic comprezsor are used. Alternating current from the inverter energizes the armature windings. This is initial mid-range package offers centrifugal compression efficiencies previously reserved for large tonnage systems only.
Conventional bearings can use as much as 10, w, while magnetic bearings re- quire only w. The VSD is integrated into the compressor housing, avoiding long leads and allowing key electronic seminxr to be refrigerant-cooled. Leave a Reply Cancel reply Your frjctionless address will not be published.
The convergence of aerospace and fricgionless proven magnetic bearings, variable-speed centrifugal compression and digital electronic 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. Small reciprocating compressors from 5 to 30 horsepower hp are commonly seen in automotive applications and are typically for intermittent duty.
Soft start and Ramp up. Rotary screw compressors Rotary screw compressors use two meshed rotating positive-displacement helical screws to force the gas into a smaller space. Traditional centrifugal compressors use roller bearings and hydrodynamic bearings, both of which consume power and require oil and lubrication system. A digitally controlled magnetic-bearing system, consisting of both permanent magnets and electromagnets, replaces conventional lubricated bearings.
Seminar On Frictionless Compressor Technology- Mechanical Seminar Topic
Over 30 successfully finished orders. Gas compressor A gas compressor is a mechanical device that increases the pressure of a gas by reducing its volume.
Frictionless oil-free using magnetic bearings. 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. Keep up the good work. The magnetic bearings normally position the rotor in the proper location, preventing contact between the rotor and other metallic surfaces. Permanent-magnetic bearings do the primary work, while digitally controlled electromagnets provide the fine positioning.
In case of power failure, within 0. Newer Post Older Post. These are usually used for continuous operation in commercial and industrial applications and may be either stationary or portable.

It features the same standard suction, discharge and economizer ports as conventional compressors It mounts in the standard way. Your email address will not be published. This feature allows the compressor to see a power outage as a normal shutdown.
Reciprocating compressors use pistons driven by a crankshaft. Many large snow-making operations like ski resorts use this type of compressor. Solution with Frictionless Compressor 1. It rotates on a levitated compresspr cushion Figure 1. 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, Refrigerating 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.

References 24 25 26 10 9 1. This compressor has high reliability, efficiency, less maintenance cost and staff. Instead of physical bearings, magnetic tschnology makes for a virtual frictionless operation. The capacitors, in turn, provide enough power to maintain levitation during coast down, allowing the motor rotor to stop and delevitate.
