What is a magnetic bearing chiller?
Magnetic-bearing chiller compressors are oil-free, variable speed compressors that can be installed as a retrofit to an existing chiller or within a new chiller. Digital, internally controlled, magnetic bearings reduce friction and eliminate the need for oil lubrication.
How does a magnetic bearing work?
An active magnetic bearing works on the principle of electromagnetic suspension based on the induction of eddy currents in a rotating conductor. This generates a current that will result in a magnetic field that is oriented opposite to the one from the magnet.
What is an instrument used for the measurement of magnetic bearings?
Observation of magnetic bearing with used of compass— Compass is the instrument for use in measuring bearing from magnetic meridian.
What is a magnetic centrifugal chiller?
Magnetic Bearing Chiller: High efficiency, Low Maintenance Magnetic-bearing centrifugal chillers use a permanent magnet synchronous compressor motor. The motor also does not require oil lubrication; oil in the chiller evaporator creates a decrease in efficiency over time as the tubes foul, lessening heat transfer.
How do you calculate magnetic bearing from true bearing?
Calculate True Bearing From Magnetic Bearing
- If Declination is East. True Bearing(T.B) = [Magnetic Bearing(M.B) + Declination]
- If Declination is West. True Bearing = [Magnetic Bearing – Declination]
What is the difference between true and magnetic bearing?
In nautical navigation the absolute bearing is the clockwise angle between north and an object observed from the vessel. If the north used as reference is the true geographical north then the bearing is a true bearing whereas if the reference used is magnetic north then the bearing is a magnetic bearing.
What is true bearing and magnetic bearing?
True bearing and magnetic bearing in geography generally refer to true north and magnetic north. True north is the direction pointing to the North Pole. On the map, true north is represented by meridians or lines of longitudes. On the other hand, magnetic north is the direction which points to the magnetic pole.
What is a York chiller?
With a wide range of types, capacities and sustainable refrigerant options, YORK® is a leader in air-cooled chiller solutions. We engineer compact, energy-efficient chillers that are easy to maintain and are tailored to fit almost any application.
What is a magnetic bearing chiller compressor?
Magnetic-bearing chiller compressors are oil-free, variable speed compressors that can be installed as a retrofit to an existing chiller or within a new chiller. Digital, internally controlled, magnetic bearings reduce friction and eliminate the need for oil lubrication.
What is the best technology for oil-free chillers?
There is another technology for oil-free chillers, which is refrigerant lubricated ceramic ball bearings. In our experience, we have opted for the magnetic bearing technology because it lives up to its efficiency and low-maintenance claims and its technology is simpler than the refrigerant lubricated system.
What are the benefits of magnetic bearings?
Magnetic bearing technology eliminates oil, mechanical seals, wear surfaces, and gears for longer machine life and increased reliability. Facility managers can bank on their chillers running at peak efficiency year after year with a design that wipes out the risk of contamination from efficiency-robbing oil buildup on to heat-transfer surfaces.
Why choose magnitude® centrifugal chiller?
The Magnitude® centrifugal chiller delivers energy savings that building owners demand. Using direct drive technology, integral variable-frequency drives, and ozone-friendly R134a refrigerant, Magnitude® is up to 40% more efficient than standard centrifugal chillers and can save up to $4 million over the life of the chiller.
