Abstract: An HVACR system includes first and second compressors arranged in parallel, a condenser, an expansion device, an evaporator, and a lubricant separator fluidly connected. The first compressor includes a first lubricant sump and a first suction inlet. The second compressor includes a second lubricant sump and a second suction inlet. The lubricant separator is disposed between the evaporator and the first and second compressors, and includes a fluid inlet and two fluid outlets. A first of the two fluid outlets is fluidly connected to at least one of the first and second lubricant sumps. A second of the two fluid outlets is fluidly connected to the first and second suction inlets. The second fluid outlet includes a nozzle disposed within a flow passage of the lubricant separator such that a space is maintained between an outer surface of the nozzle and an inner surface of the flow passage.

Abstract: A scroll compressor is disclosed. The scroll compressor includes a compressor housing; an orbiting scroll member disposed within the housing; a non-orbiting scroll member disposed within the housing, wherein the orbiting scroll member and the non-orbiting scroll member are intermeshed thereby forming a compression chamber within the housing; and an endplate secured to the non-orbiting scroll member. The endplate includes a check valve surface configured to provide a stop for a check valve of the scroll compressor, a radial sealing surface configured to receive a radial seal, an unloading mechanism surface configured to provide a stop for an unloading mechanism, and a pressure chamber for controlling the unloading mechanism, the endplate also including an aperture that fluidly connects the compression chamber and a discharge chamber of the scroll compressor.

Abstract: An asymmetric scroll compressor includes a compressor housing. An orbiting scroll member and a non-orbiting scroll member disposed within the compressor housing. The orbiting scroll member and the non-orbiting scroll member each includes a baseplate and a wrap extending from the baseplate. The orbiting scroll member and the non-orbiting scroll member intermeshed to form a plurality of compression pockets. A driveshaft affixed to the orbiting scroll member and configured to orbit the orbiting scroll member from a first orbital position to a second orbital position. A communication port disposed on the baseplate of one of the orbiting scroll member and the non-orbiting scroll such that: in the first orbital position, the communication port communicates with a first enclosed pocket of the plurality of compression pockets, and in the second orbital position, the communication port communicates with a second enclosed pocket of the plurality of compression pockets.

Abstract: Devices, systems, and methods are disclosed for reducing leakage current in compressors, such as for heating, ventilation, and air conditioning, and refrigeration (HVAC/HVACR) systems. Several embodiments include a sensor for measuring the isolation resistance of an enclosure of a compressor. The sensor can be electronically coupled to a controller that is configured to activate a heating element mechanically coupled to the enclosure when the controller determines that the isolation resistance measured by the sensor falls indicates that the compressor is at risk of faulting. Activating the heating element causes the refrigerant mixed within the oil to evaporate, which lowers the liquid level within the compressor.
