BLUE STAR VFD DRIVEN CENTRIFUGAL CHILLER Features Benefits

BLUE STAR VFD DRIVEN CENTRIFUGAL CHILLER

Features / Benefits Ø Capacity range from 90 TR to 300 TR. Available from Sept. 2010 Ø 4 Models 90, 150, 180 & 300 TR. Ø More than 300 TR Model after Sept. 2011. Ø Energy saving achieved up to 30% at part load. Ø Ultra quiet compressor, No need of Acoustic Jacket or Enclosure. Ø Lesser starting current hence lesser generator size, smaller Electrical Isolator (MCCB, SFU) Ø Lesser foot print compared to conventional chillers. Ø Lower installation cost. Ø User friendly touch screen controller to monitor. Ø Flooded coolers for enhanced efficiency. Ø Use less space & Light Weight than conventional chillers.

Turbocor Compressor Twin Turbine Centrifugal Compressor. Totally Oil Free Integrated Variable Speed Drive Magnetic Bearing Onboard Digital Electronics

Turbocor Compressor Parts Inverter speed control Soft Start (<2 Amp Inrush) 2 stage, direct drive, hermetic centrifugal compressor Permanent magnet motor Inlet Guide Vanes Motor and bearing control

Why a Variable Speed Drive? The Compressor’s speed adjusts automatically to match the load and operating conditions for maximum efficiency. The slower the compressor’s speed, the greater the energy savings. Power (Speed)3

Magnetic Bearings ØProvide totally oil free operation ØRotor shaft and impellers levitate during rotation and float on magnetic cushion ØThe magnetic bearings have 500 times less friction loss that conventional bearings Uses 0. 5% of the energy required for conventional bearings for same service. ØEliminate the ability of oil to contaminate the refrigerant (key to sustainability) ØEliminate cost of oil management systems (hardware and controls) ØIncreases equipment life through elimination of wear surfaces ØDue to absence of Oil, eliminates oil circulation, Separation & cooling problems as compared to conventional System.

Magnetic Bearing System Magnetic bearings and sensors keep the shaft properly centered and positioned at all times.

ARI Standard 550/590 INTEGRATED PART LOAD PERFORMANCE (IPLV) A method of measuring total chiller performance over a defined range of part load conditions. As Per ARI 550/590 -2003 IPLV = 1/[(0. 01/A) + (0. 42/B) + (0. 45/C) + (0. 12/D)] Where : A = k. W/ton at 100% load point B = k. W/ton at 75% load point C = k. W/ton at 50% load point D= k. W/ton at 25% load point 99% of Weightage to 75% & Below Loads. Where Turbocor Compressor is Most Efficient than any other Compressor.
