The
simple straightforward design of Copeland® Scroll™ compressors makes them
inherently more efficient. That's why leading manufacturers so often specify
Copeland® Scroll™ compressors for systems designed to meet the highest
efficiency levels.
Since there are no pistons to compress gas, scroll
compressors achieve 100% volumetric efficiency, which provides reduced energy
costs in many applications. Re-expansion losses, which typically
occur with each piston stroke in reciprocating models, are eliminated.
Similarly, losses at valves are eliminated, because suction valves do not exist.
During operation,
centrifugal force maintains nearly continuous compression and constant,
leak-free contact. Separation of suction and discharge gases reduces heat
transfer loss.Copeland® Scroll™ compressors are approved for use with most
refrigerants, including R-22, R-404A, R-507, R-134a, R-407C, and R-410A.New
technologies that will further improve scroll system efficiency include:
