Copeland Scroll Compressors

Copeland Scroll compressors are used on most Advantage portable and central water chillers, from 3 to 90 tons, air cooled and water cooled units.

• Copeland Scroll compressors have several benefits over other types of compressors. Scroll Compressors...
• Have only three moving parts. Fewer moving parts mean increased reliability. By comparison, piston compressors have up to nine moving parts per cylinder. Benefit: fewer maintenance calls.
• Do not use complex internal suction and discharge valves. Because of this, scroll compressors are more tolerant to liquid refrigerant and debris. Benefit: durability.
• Are more efficient over their entire operating range, thanks to less cycling and 100% volumetric efficiency. Benefit: higher efficiency.
• Are compact in overall size, are light weight, and are simple in design. Benefit: easy service and maintenance.
• Operate at a lower sound and vibration levels. Benefit: quiet operation.

Step 1

Refrigerant enters outer opening as one scroll orbits the other.

Step 2

The open passage is sealed and refrigerant is drawninto the compression chamber.

Step 3

As one scroll continue orbiting, the refrigerant is compressed into an increasingly smaller, crescent-shaped pocket.

Step 4

By the time the refrigerant reaches a central port in the stationary scroll, it has achieved maximum (discharge) pressure.

Step 5

During actual operation, all passages are in various stages of compression at all times, resulting in near-continuous intake and discharge for optimum performance.
