Abstract: A lubricant supply system is for a compressor that compresses a first working fluid in a heat transfer circuit. The lubricant supply system includes a lubricant tank, a lubricant pathway for supplying lubricant from the lubricant tank to one or more bearings of the compressor, and a lubricant refrigeration system with a lubricant heater and a lubricant cooler. The lubricant heater configured to heat the lubricant discharged from the one or more bearings and the lubricant cooler configured to cool the lubricant flowing through the lubricant pathway. A method of lubricating a compressor includes heating the lubricant, directing the lubricant from a lubricant tank through a lubricant pathway to one or more bearings of the compressor, and cooling the lubricant passing through the lubricant pathway.

Abstract: An electronic actuator assembly operates an in-line valve. A valve seat of the in-line valve is surrounded by a plate. The plate can include one or more openings configured to allow fluid to pass through the plate. A perimeter of the plate outside of the openings can be configured to have ends of pipes joined on either side of the plate. The in-line valve can be operated by an electronic actuator. The electronic actuator can be powered by a supply line that enters the assembly through the plate. The electronic actuator assembly can be incorporated in to a fluid circuit to serve as an expander. The electronic actuator can be located in a housing to direct flow around the electronic actuator. The electronic actuator can be installed in place of an orifice plate of an existing fluid circuit of a heating, ventilation, air conditioning, or refrigeration (HVACR) system.

Abstract: A refrigerant circuit is disclosed. The refrigerant circuit includes a compressor, a condenser, a first expansion device, an economizer, a second expansion device, and an evaporator fluidly connected. A working fluid flows through the refrigerant circuit. A bypass segment is fluidly connected to the refrigerant circuit. A portion of the working fluid is provided from the refrigerant circuit to the bypass segment from a location in the refrigerant circuit disposed between the condenser and the evaporator with respect to flow of the working fluid. The portion of the working fluid flows through the bypass segment in a flow enabled state and is provided to a location in the refrigerant circuit disposed between the economizer and the evaporator with respect to flow of the working fluid. A vortical flow is induced at the location in the refrigerant circuit disposed between the economizer and the evaporator.
