    摘要： A scroll compressor includes a compressor housing containing an orbiting scroll member, a non-orbiting scroll member, a pair of bands disposed between the non-orbiting scroll member and the compressor housing, a suction chamber, a discharge chamber, and an intermediate injection chamber defined by the pair of bands. The non-orbiting scroll member includes an intermediate injection port fluidly connecting the intermediate injection chamber to at least one compression pocket formed by the intermeshed scroll members. A heating, ventilation, air conditioning, and refrigeration system including a refrigerant circuit with a condenser, at least one expander, an evaporator, and the scroll compressor fluidly connected. A method of making a scroll compressor includes placing an upper portion of a compressor housing over a non-orbiting scroll member with bands disposed therebetween, and interference fitting the upper portion onto the non-orbiting scroll member via the bands.

    摘要： A heating, ventilation, air conditioning, and refrigeration (HVACR) system including a scroll compressor is disclosed. The scroll compressor includes a compression mechanism having an orbiting scroll and a non-orbiting scroll aligned in meshing engagement. The scroll compressor also includes an electric motor. A bearing housing is disposed between the compression mechanism and the electric motor. A lubricant drain is formed in the bearing housing. The lubricant drain is disposed in a location that lubricant draining from the bearing housing via the lubricant drain is directed toward the electric motor.

    摘要： A scroll compressor includes a compressor housing, an orbiting scroll member, a non-orbiting scroll member, an economizer injection inlet, and a discharge outlet. The orbiting scroll member and the non-orbiting scroll member are disposed within the compressor housing. The orbiting scroll member and the non-orbiting scroll member are intermeshed thereby forming a compression chamber within the compressor housing. The non-orbiting scroll includes a plurality of compression inlet ports. An economizer injection inlet is formed through the compressor housing and in fluid communication with the compression chamber via the compression inlet ports. The discharge outlet is in fluid communication with the compression chamber.

    摘要： A scroll compressor includes an orbiting scroll member disposed within a compressor housing. The orbiting scroll member has a substantially circular baseplate and a generally spiral wrap extending from its base. A first seal is disposed proximal to the outer periphery of the orbiting scroll baseplate to provide an external seal between the baseplate and the housing. A second seal is disposed radially inward from the first seal to provide an internal seal between the baseplate and the housing. A space between the internal seal and the external seal defines a balance piston chamber. The balance piston chamber is pressurized via a high or intermediate pressure oil source to reduce thrust loading on the baseplate caused by an axial pressure differential across the baseplate.

    摘要： A scroll compressor includes a compressor housing containing an orbiting scroll member, a non-orbiting scroll member, bands disposed between the non-orbiting scroll member and the compressor housing, a suction chamber, a discharge chamber, and one or more intermediate injection chamber defined by the bands. The non-orbiting scroll member includes one or more intermediate injection ports fluidly connecting the one or more intermediate injection chambers to at least one compression pocket formed by the intermeshed scroll members. A heating, ventilation, air conditioning, and refrigeration system includes a refrigerant circuit with a condenser, an expander, an evaporator, and the scroll compressor fluidly connected. A method of making a scroll compressor includes placing an upper portion of a compressor housing over a non-orbiting scroll member with bands disposed therebetween, and interference fitting the upper portion onto the non-orbiting scroll member via the bands.
