Copeland Scroll compressors are used on most Advantage portable and central water chillers, from 3 to 90 tons, air cooled and water cooled units.
Operational sequence of Scroll Compressors
Refrigerant enters outer opening as one scroll orbits the other.
The open passage is sealed and refrigerant is drawninto the compression chamber.
As one scroll continue orbiting, the refrigerant is compressed into an increasingly smaller, crescent-shaped pocket.
By the time the refrigerant reaches a central port in the stationary scroll, it has achieved maximum (discharge) pressure.
During actual operation, all passages are in various stages of compression at all times, resulting in near-continuous intake and discharge for optimum performance.
