Abstract
A scroll expresser of a refrigerant system includes a non-orbiting expander scroll plate and an orbiting expander scroll plate which form a plurality of expansion chambers and a non-orbiting compressor scroll plate and a orbiting compressor scroll plate which form a plurality of compression chambers. The scroll expresser expands high pressure refrigerant in the expansion chambers to low pressure vapor refrigerant and liquid refrigerant. The liquid refrigerant exits the scroll expresser for evaporation. The vapor refrigerant is compressed in the compression chambers and mixes with the refrigerant exiting the compressor. Alternatively, the orbiting scroll plates are integrated into one component.
