Simple Design with 70% Fewer Parts
Fewer parts than an equal capacity
reciprocating compressor means significant reliability and efficiency benefits.
The single orbiting scroll eliminates the need for
pistons, connecting rods, wrist pins and valves.
Fewer parts lead to increased reliability. Fewer moving parts, less rotating mass and less internal friction means greater efficiency
than reciprocating compressors.
Patented 3-D Scroll Compliance
Trane 3-D Scroll compliance provides
important reliability and efficiency benefits. 3-D compliance allows the orbiting
scrolls to touch in all three dimensions, forming a
completely enclosed compression chamber which leads to increased efficiency. In addition,
3-D compliance means the orbiting scrolls only touch
with enough force to create a seal; there is no wear
between the scroll plates. The fixed and orbiting scrolls are made of high strength
cast iron which results in less thermal distortion,
less leakage, and higher efficiencies. The most outstanding feature of the scroll compressor
3-D compliance is that slugging will not cause failure.
In a reciprocating compressor, however, the liquid or dirt can cause serious damage.
Low Torque Variation
The 3-D Scroll compressor has a very
smooth compression cycle; torque variations are only 30 percent of that produced
by a reciprocating compressor. This means that the
scroll compressor imposes very little stress on the motor resulting in greater reliability. Low torque variation reduces noise and vibration.
Suction Gas Cooled Motor
Compressor motor efficiency and reliability is further optimized with the latest
scroll design. Cool suction gas keeps the motor cooler
for longer life and better efficiency.
Proven Design Through Testing and
Research With over
twenty years of development and testing, Trane 3-D
Scroll compressors have undergone more than 400,000 hours of laboratory testing and field operation. This work combined with
over 25 patents makes Trane the worldwide leader in air
conditioning scroll compressor technology.
