Compressor system with self contained lubricant sump heater
摘要：
Decreased lubricity of lubricating oil (36) in a compressor utilized in a vapor compression refrigeration system as well as decreases in thermal efficiency of such a system during start-up are avoided in a compressor structure including a housing (10) containing a compressing mechanism (28), (40) therein, an outlet (34) for the compression mechanism, an inlet (30), (32) for gas to compressed to the compressing mechanism (28), and a sump (24) within the housing (10) for containing the lubricant (36). A conduit (54), (60), (62), (64), (66) is utilized to direct compressed gas from the outlet (34) into heat exchange relation with the lubricant (36) within the sump (24) to drive any refrigerant in solution in the lubricant out of solution so as to improve lubricity and maintain system efficiency.
