Abstract
The open drive motor for a refrigeration apparatus is mounted in a hermetic casing containing a quantity of a mixture consisting of a refrigerant and a lubricating oil. A passage extends from the upper portion of the casing to an auxiliary condenser, and a second passage returns condensed mixture to the motor casing. The auxiliary condenser is cooled by a metered flow of refrigerant from the condenser of the apparatus. The flow is metered to supply the condensed mixture in sufficient quantity to effectively cool the motor during continuous operation of the motor at full load.
