    摘要: A multi-stage compressor unit for a refrigeration system configured to circulate a refrigerant comprises a first compressor sub-unit having a first stage and a second stage, and a second compressor sub-unit in parallel with the first compressor sub-unit and having a first stage. The first and second stages of the first compressor sub-unit each have a suction port and a discharge port. The first compressor sub-unit is configured to receive and compress a first portion of the refrigerant from an evaporator. The first stage of the second compressor sub-unit is configured to compress a second portion of the refrigerant.

    摘要: A refrigeration system (20A) comprises an evaporator (27), a two-stage compressor (32) for compressing a refrigerant, a second compressor (34) for compressing the refrigerant, a heat rejecting heat exchanger (24) for cooling the refrigerant, a first economizer circuit (25A), and a second economizer circuit (25B). The first economizer circuit (25A) is configured to inject refrigerant into an interstage port (48) of the two-stage compressor (32). The second economizer circuit (25B) is connected to the second compressor (34).

    摘要: A scroll compressor includes a feature for location of a housing shell section off of one of the scroll compressor bodies. According to this aspect, a scroll compressor comprises a housing including a shell section; scroll compressor bodies having respective bases and respective scroll ribs that project from the respective bases and which mutually engage about an axis for compressing fluid; and a drive unit operative to facilitate relative movement between the scroll compressor bodies. The shell section is located axially relative to a remainder of the housing off of one of the scroll compressor bodies.
