Ruud is the only manufacturer to use Scroll compressors in its entire
residential Air conditioner and heat pump product line.
Scroll Technology: The Smoothest, Quietest, Most Efficient Compressor
Technology Ever Invented.
No other manufacturer today offers the
benefits of Scroll technology throughout its entire residential air
conditioning product line. It's an advancement that achieves higher
efficiency and durability at the same time. Scroll compressors use
advances engineering and flow dynamics to more efficiently and smoothly
compress gas refrigerant. Old-fashioned reciprocating compressors use
pistons and valves to compress and move gas. but with a scroll compressor,
these noisy high-wear moving parts are eliminated.
Scroll Compressors Are Simple.
Two spiral-shaped members simply fit together,
forming crescent-shaped gas pockets. One member remains stationary, while
the other is allowed to orbit around the stationary one.
Gas is drawn into the outer pocket created
by the two members, sealing off the open passage. As the spiral motion
continues, the gas is forced toward the center of the scroll as the pocket
continuously becomes smaller in volume, creating higher gas pressures.
When the compressed gas reaches the center of the fixed scroll member, it
Several pockets of gas are compressed
simultaneously. The result is a smooth, nearly continuous compression
cycle -- smoother, more efficient, quieter than any other kind of
Because of its axial compliance, Copeland’s
Compliant Scroll Compressors create a continuous seal to ensure that
excessive wear will not reduce performance and efficiency. In fact, the
Compliant Scroll actually “wears in” over time to improve its operating
characteristics and reduce compressor sound.
Strong engineering and manufacturing support explains why the Copeland
Scroll is the leading scroll compressor in quality and reliability. The
Copeland Scroll provides you with higher efficiency, lower sound levels,
superior durability and unsurpassed reliability.
Copeland's unique patented scroll design enhances
reliability by its superior ability to survive liquid problems; the scroll
spirals separate when liquid refrigerant or foreign material is
Durability is based on a very robust
design and contains only a few moving parts. Because the Copeland Scroll
starts unloaded, strain on the motor is considerably reduced. At rough
operating conditions, the spirals come apart, protecting the compressor
from damage. In fact, the performance of a Copeland Scroll gets better
with time: it "wears in", not out.
The Copeland Scroll consistently provides end-users with
more comfort, due to humidity and temperature control, as a result of its
superior load matching capability. Superior system efficiency is achieved
through Copeland's Scroll leak-free compression, low heat transfer from
discharge to suction, smooth continuous compression, and unobstructed gas
flow. This high efficiency enables OEM system manufacturers to get
significant savings in the design of their condensers. End-users benefit
from substantial energy cost reductions.
Today's market puts more emphasis on low-sound systems.
The Copeland Scroll is by far the quietest compressor in the industry
since its compression is accomplished through a continuous, smooth
compression process. There is no noise associated with valves or piston
strokes. Discharge gas and pulse and vibration are kept at a low level.
|The concept of
compressing a gas by turning one involute form – or “scroll” –
against another around a common axis is nearly a century old.
It wasn’t until the late 1980s, however that one company –
Copeland – turned theory into practical reality, using
sophisticated, computer-assisted design and manufacturing
methods to achieve the critical tolerances required. In the
years since, Copeland has become the leader in scroll
compressor applications, with nine scroll manufacturing
facilities on three continents and millions of units installed
Copeland Scroll® compressors employ two identical,
concentric scrolls, one inserted within the other. One scroll
remains stationary as the other orbits around it. This
movement draws gas into the compression chamber and moves it
through successively smaller “pockets” formed by the scroll’s
rotation, until it reaches maximum pressure at the center of
the chamber. There, it’s released through a discharge port in
the fixed scroll. During each orbit, several pockets are
compressed simultaneously, so operation is virtually
