Refrigeration Compressor
The compressors are one of the most important parts of the refrigeration cycle. The compressor compresses the refrigerant, which flows to the condenser, where it gets cooled. It then moves to the expansion valve, and theevaporator and it is finally sucked by the compressor again. For the proper functioning of the refrigeration cycle, the refrigerant must be compressed to the pressure corresponding to the saturation temperature higher than the temperature of the naturally available air or water. It is the crucial function that is performed by the compressor. r

How a Scroll Compressor Works
Unlike reciprocating technology with many moving parts, the Copeland scroll compressor has one scroll or spiral orbiting in path defined by a matching fixed scroll. The fixed scroll is attached to the compressor body. The orbiting scroll is couple to the crankshaft in orbit rather then rotated. The orbiting motion creates a series of gas pockets traveling between the two scrolls. On the outer portion of the scroll the pocket draw in gas, then move it to center of the scroll where it’s discharged. As the gas moves in the increasing smaller inner pocket, the temperature and pressure increase to the desired discharged pressure.
Copeland's Compliant Scroll technology is based on the concept of compliance. Compliance refers to the method in which the two scroll members interact to simultaneously achieve high efficiency and durability. Copeland's unique and patented approach -- achieving both radial and axial compliance -- provides the following important advantages:
- Continuous flank contact, maintained by centrifugal force, minimizes gas leakage and maximizes efficiency.
- Radial compliance allows the scroll members to separate in the presence of liquid refrigerant or debris, thereby substantially improving durability and reliability.
- Axial compliance allows the scroll to remain in continuous contact in all normal operating conditions, ensuring minimal leakage without the use of tip seals.
- Both radial and axial compliance allow the scroll members to actually "wear in" rather than wear out.
