The Trane CVGF
packaged centrifugal water chillers using HFC-134a refrigerant
consist of a hermetic two stage, gear-drive centrifugal
compressor, evaporator, condenser, interstage economizer, unit-mounted
microprocessor based control panel
and compressor motor starter. The chiller is completely factory
assembled and run tested before shipment. |

Compressor
Two-stage centrifugal compressor with high-strength aluminum
alloy fully shrouded impellers. The impellers are tested at 25
percent over design operating speed. The rotating assembly is
dynamically balanced for vibration of less than 5.1 mm/s (0.2
ips peak velocities) at nominal operating speeds. The control
system affords 100 - 20 percent capacity modulation by
electrically actuated guide vanes upstream of each impeller.
Drive Train
The drive train consists of helical bull and pinion gears. Gear
tooth surfaces are case hardened and precision ground. The one-piece
impeller shaft is supported by hydrodynamic thrust and radial
bearings.
Motor
The motor is a hermetic, liquid refrigerant cooled, two-pole,
low-slip squirrel cage induction motor. A radial hydrodynamic
bearing and duplex angular contact ball bearings support the
rotor assembly. Windingembedded sensors provide positive
thermal protection.
Lubrication System
The lubrication system consists of an internal oil sump with
heaters, positive displacement oil pump, brazed plate
condenser-cooled oil cooler, and oil distillation/return
line. |
