| Features and Benefits • Trane 3-D® Scroll Compressor 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 compressor chamber which leads to increased
efficiency. In addition, 3-D compliance means the orbiting scrolls only touch with enough
force to create a seal so 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 with torque variations that are only 30 percent of that produced by a reciprocating
compressor. This means the scroll compressor imposes very little stress on the motor for
greater reliability. Low torque variation means reduced noise and vibration.

Suction Gas Cooled Motor
Compressor motor efficiency and reliability is further
optimized with this 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. |
