Features and
Benefits
Air Handling Section
In accordance to the ASHRAE Standard
62-89 for Indoor Air Quality, Trane has
developed an exclusive and innovative
design for the drain pan. This design
insures proper drainage, preventing
conditions of water stagnation that could
result in microbial growth.
All the air handlers feature a factory
installed belt drive and ball bearing
evaporator fan with adjustable shelves.
The unit can be installed indoors; the
condenser air can be ducted to the
outside or installed in a remote location.
For free horizontal application, the
optional discharge plenum with
aluminum grills insures a quiet
operation and maintains the aesthetics
of the units.
In the return section an optional
aluminum grill grants an easy and
elegant installation.

Scroll Compressor
offers significant efficiency and reliable
benefits. With fewer moving parts than
comparable reciprocating compressors,
there is less internal friction and
therefore greater efficiency. A smooth
compressor cycle, due to the low torque
variation, creates less stress on the
motor for greater reliability and
efficiency.
How the Scroll Compressor Works
General
The compressor has two scrolls. The top
scroll is fixed and the bottom scroll
orbits. Each scroll has walls in a spiral
shape that intermesh.
Inlet — First Orbit
As the bottom scroll orbits, two
refrigerant gas pockets are formed and
enclosed.
Compression — Second orbit
The refrigerant gas is compressed as the
volume is reduced closer to the center of
the scroll.
Discharge — Third Orbit
The gas is compressed further and
discharged through a small port in the
center of the fixed scroll.
