Abstract: The present invention provides the art with a scroll machine which has a plurality of built-in volume ratios along with their respective design pressure ratios. The incorporation of more than one built-in volume ratio allows a single compressor to be optimized for more than one operating condition. The operating envelope for the compressor will determine which of the various built-in volume ratios is going to be selected. Each volume ratio includes a discharge passage extending between one of the pockets of the scroll machine and the discharge chamber. All but the highest volume ration utilize a valve controlling the flow through the discharge passage.

Abstract: The present invention provides the art with a scroll machine which has a plurality of built-in volume ratios along with their respective design pressure ratios and comprising a shell having an end cap, said end cap defining a barrier between a chamber defined by said shell and an environment outside said scroll machine; a first scroll member disposed within said chamber having a first spiral wrap projecting outwardly from a first end plate; a second scroll member disposed within said chamber having a second spiral wrap projecting outwardly from second end plate, said second scroll wrap being interleaved with said first spiral wrap; a drive member for causing said spiral wraps to orbit with respect to one another whereby said spiral wraps create pockets of progressively changing volume between a suction pressure zone at a suction pressure and a discharge pressure zone at a discharge pressure; a first annular seal engaging said end cap and said first scroll member, said first annular seal being disposed around a hole extending through said end cap.

Abstract: A scroll compressor incorporates a vapor injection system where only one vapor injection port is utilized. The single vapor injection port injects refrigerant vapor into two of the initially formed enclosed spaces. The scrolls of the scroll compressor are designed with asymmetric wraps where the non-orbiting scroll wrap extends angularly further than the orbiting scroll wrap.

Abstract: A refrigeration system has a compressor which incorporates fluid injection into one or more of the fluid pockets. A source of fluid for injection into the pockets is attached directly to the shell of the compressor to eliminate the need for having fluid piping between the source of fluid and the compressor. The source of fluid can be a flash tank which increases the capacity and efficiency of the system or the source of fluid can be a heat exchanger which also increases the capability and efficiency of the system.
