Abstract
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.
