SCROLL COMPRESSOR WITH INTERMEDIATE INJECTION

A scroll compressor (100) includes a compressor housing (102) containing an orbiting scroll member (114), a non-orbiting scroll member (112), bands (180, 182) disposed between the non-orbiting scroll member and the compressor housing, a suction chamber (140), a discharge chamber (142), and one or more intermediate injection chamber (144) defined by the bands. The non-orbiting scroll member includes one or more intermediate injection ports (150) fluidly connecting the one or more intermediate injection chambers to at least one compression pocket (117) formed by the intermeshed scroll members. A heating, ventilation, air conditioning, and refrigeration system (1) includes a refrigerant circuit (5) with a condenser (20), an expander (30, 32), an evaporator (50), and the scroll compressor (10) 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.
