REFRIGERATION CHILLER, APPARATUS FOR PUMPING BOTH REFRIGERANT AND LUBRICANT IN A REFRIGERATION CHILLER, AND A METHOD FOR COOLING THE COMPRESSOR DRIVE MOTOR IN A REFRIGERATION CHILLER AND FOR DELIVERING LUBRICANT TO A SURFACE THEREIN THAT REQUIRES LUBRICATION
REFRIGERATION CHILLER, APPARATUS FOR PUMPING BOTH REFRIGERANT AND LUBRICANT IN A REFRIGERATION CHILLER, AND A METHOD FOR COOLING THE COMPRESSOR DRIVE MOTOR IN A REFRIGERATION CHILLER AND FOR DELIVERING LUBRICANT TO A SURFACE THEREIN THAT REQUIRES LUBRICATION
A single motor drives both oil and refrigerant pumps in a refrigeration chiller, the motor and oil pump being disposed in the chiller's oil supply tank and the refrigerant pump being disposed exterior thereof. The refrigerant pump pumps liquid refrigerant to the chiller's compressor section so as to cool the motor by which the compressor is driven while the oil pump pumps oil to chiller locations that require lubrication when the chiller is in operation.
