DRIVE
October 8, 2025
A vapor cycle cooling system includes first and second compressor (112B) systems in parallel with one another, each compressor system including a motor, a motor controller (180, 280, 380, 480), and a first compressor (112A, 212A) in series with a second compressor (112B); a condenser (102, 202, 302) fluidically coupled to each compressor system; a filter drier (138, 238, 338), in series with, and fluidically coupled to the condenser (102, 202, 302); a first expansion device in series with, and fluidically coupled to, a flash heat exchanger (106, 206), the flash heat exchanger (106, 206) fluidically coupled to a second expansion device, the second expansion device fluidically coupled to a first evaporator (266), the first evaporator (266) fluidically coupled to each compressor system; a system controller (180, 280, 380, 480) electrically coupled to each motor controller (180, 280, 380, 480); and a motor and motor controller (180, 280, 380, 480) cooling loop fluidically coupled to the filter drier (138, 238, 338) and each motor, wherein the vapor cycle cooling system is configured to cool one or more thermal loads (264) for a vehicle.
