Method and system for cooling a motor-compressor with a closed-loop cooling circuit

A fluid compression (100) system is disclosed having a hermetically-sealed housing (110) with a double-ended motor (102) and at least one compressor (104) arranged therein. The double-ended motor may drive both the compressor and at least one blower device (128) coupled to the housing or otherwise a...

description	A fluid compression (100) system is disclosed having a hermetically-sealed housing (110) with a double-ended motor (102) and at least one compressor (104) arranged therein. The double-ended motor may drive both the compressor and at least one blower device (128) coupled to the housing or otherwise arranged within the housing and configured to circulate a cooling gas throughout the housing and thereby cool the motor and accompanying radial bearings (120). The blower device circulates the cooling gas through a closed-loop circuit which may include a heat exchanger (156) and gas conditioning skid (157). Carbon ring seals (146) may be used to seal the shaft (108) on both sides of the compressor so as to prevent the migration of liquid and solid contaminants into the closed-loop cooling circuit. A second compressor and a second blower may also be simultaneously driven by the double-ended motor.
