outstanding efficiency, flexibility and
installation ease, and you have an
unbeatable combination for years of
worry-free service and operation.
Manufacturing Control
Trane’s exclusive control over the
design and manufacturing of all
major components is unique in the
industry. This approach assures total
control over both the quality and
reliability of these components and
allows us to custom match
components to deliver the best in
split system performance.
Designing the Details
Careful attention was given to
designing the details — from control
wiring to the access panels. Odyssey
units feature time-saving colored
and numbered wiring and
removable panels which allow
complete access to all major
components and controls. All
outdoor units feature external high
and low pressure switches for easy
diagnosing and servicing of the unit.
Service valves with gauge ports are
provided on all units.
Standardized Cabinets
In addition, all cabinets have been
standardized. When you are
servicing an outdoor unit or an air
handler, all components are in the
same location from unit to unit.
Filters
The 5, 7½ and 10 ton air handlers are
supplied with 1" throwaway filters as
standard. The filter racks were
designed to easily convert for
installation of 2" filters. The 15 and
20 ton air handlers have 2" filters as
standard.

Condensing Units Options
The 7½ and 10-ton single
compressor models feature single
refrigeration circuitry, lowering job
installation costs by requiring only
one set of refrigerant lines. These
units are ideal for low cost, new
construction, building renovation
and unit replacement jobs.
In addition, Odyssey includes 15 and
20-ton dual compressor units to give
true stand-by protection; if one
compressor fails, the second will
automatically start-up. Also, the first
compressor can be serviced without
shutting down the unit since the
refrigerant circuits are independent.
Dual compressors also provide high
energy savings. Most buildings are
designed for peak load requirements
even though the building typically
operates at less than peak load.
During light load conditions only one
compressor functions to maintain
the space comfort, reducing energy
use. For instance, the EER of the 15
ton unit at ARI conditions is 10.1 and
at part load conditions it is 11.6.
Trane split systems have been
specified in thousands of
applications. You’ll find Odyssey will
win you even more jobs with its
compact, manageable cabinet which
will save time and money for rigging
and installation and permit Trane to
replace almost any unit —
effortlessly.
Each heat pump unit can operate to
50°F as standard in the cooling
mode. An accessory Head Pressure
Control gives you the capability to
operate to 0°F. All heat pumps offer
these accessories:
• Head Pressure Control
• Coil Guard Kits
• Isolators - both Rubber-in-Shear
and Spring Type
• Anti-Short-Cycle Kit
• Time Delay Relay
Air Handlers Offer More
Flexibility
Flexibility is a key to meeting
changing market requirements.
Odyssey split systems offer not only
heat pumps, but also convertible air
handlers.
The air handlers can be installed
either vertically in a mechanical
room or horizontally above a ceiling
— and it doesn’t require any removal
of panels to make either airflow
application work.
Figure 2.
These air handlers have a double
sloped condensate drain pan that
allows for either airflow
configuration. The drain pan can
easily be removed for cleaning.
All the air handlers feature factory-
installed belt drive and ball bearing
evaporator fans with adjustable
sheaves for maximum airflow
performance. In fact, the standard
motor on the 10-ton air handler will
deliver 4000 cfm at 1.4" ESP. Plus
oversized motors are available for
higher static applications.

Odyssey — A Complete
Split System
Odyssey delivers the flexibility to
select a complete system that meets
your particular job requirements.
Air handlers are designed, tested and
rated with outdoor units to let you
select the proper match between
capacity and load. Also, these
matched systems can be quickly
engineered for specific applications
using Trane’s computerized selection
and load programs.
Odyssey Lowers Installation Costs
Your installation costs are reduced
with Odyssey Split. Both outdoor
units and air handlers are factory
packaged and assembled so jobsite
installation is quick and easy. You get
a complete system, with all the
components, controls and the
internal wiring, factory-installed for a
smooth jobsite start-up.
Unlike some competitive models the
following components are factory-
installed in Trane air handlers:
• Single Point Power Entry
• Blower Wheel and Housing
• Evaporator Motor with Sheaves
and Pulleys
• Low Voltage Terminal Board
•Transformer
• Contactor
• Fan Relay
• DX Coil with complete
Refrigeration Circuitry
• Expansion Valve and Check
Valves
There’s no need to install
components and put together the air
handler on the job. This provides you
with less labor cost and fewer
chances for installation errors which
cause callbacks. All this means
saving you money both in
replacement and new construction
applications.

Application of this product should be
within the catalogued airflow and
performance considerations.
Clearance Requirements
The recommended clearances
identified with unit dimensions
should be maintained to assure
adequate serviceability, maximum
capacity and peak operating
efficiency. Actual clearances which
appear inadequate should be
reviewed with a local Trane
Representative.
180° Blower Rotation
The 5, 7½ and 10 ton air handler
blower section can be rotated 180° to
change the discharge pattern. This
modification must be done in the
field and requires an additional kit.
See unit installer's guide.
Low Ambient Cooling
As manufactured, these units can
operate to 50°F in the cooling mode
of operation. An accessory head
pressure control will allow operation
to 0°F outdoor ambient. When using
these units with control systems
such as bypass changeover Variable
Air Volume, make sure you consider
the requirement for a head pressure
control to allow low ambient
cooling.

Cooling Capacity
Step 1.
Calculate the building’s total and
sensible cooling loads at design
conditions.
Step 2.
Size the equipment using Ta b l e 3 .
Match the cooling loads at design
conditions.
Example: The following are the
building cooling requirements:
a. Electrical Characteristics:
460/60/3
b. Summer Design Conditions:
Entering Evaporator Coil:
80°F DB/67°F WB Outdoor
Ambient: 95°F
Total Cooling Load: 90 MBh
c. Sensible Cooling Load: 64
MBh
d. Airflow: 3000 cfm
External Static Pressure:
0.77 inches of water gauge
Ta b l e 3 shows that TWA090A4 with
TWE090A has a gross cooling
capacity of 91.1 MBh and 65.9 MBh
sensible capacity at 95°F DB ambient
and 3000 cfm with 80°F DB/67°F WB
air entering the evaporator.
To find the net cooling capacities, fan
motor heat must be subtracted.
Determine the total unit static
pressure:
External Static Duct System 0.77 in.
Standard Filter 1 in. 0.10 in.
Supplementary Electric Heat 0.23 in.
Total Static Pressure 1.10 in.
Note: The Evaporator Fan
Performance Table has
included the effect of a 1 in.
filter already. Therefore, the
actual Total Static Pressure is
1.10 - 0.10 = 1.0 0 in. With
3000 cfm and 1.00 in.,
Ta b l e 1 7 shows a 1.17 bhp.
Note: The formula below the table
can be used to calculate Fan
Motor Heat:
3.5 X bhp = MBh
3.5 X 1.17 = 4.09 MBh
Net Total Cooling Capacity =
91.1 MBh - 4.09 = 87.01 MBh
Net Sensible Cooling Capacity =
65.9 MBh - 4.09 = 61.81 MBh
Heating Capacity
Step 1.
Calculate the building heating load
using the Trane calculation form or
any other standard accepted
method.
Step 2.
Size the equipment using Ta b l e 11 to
match the heating loads at design
conditions. The following are
building heating requirements:
a. Total Heating Load: 95.0 MBh
b. Outdoor Ambient (Winter):
17°F DB
c. Indoor Return Temperature:
70°F DB
d. Airflow: 3000 cfm
Ta b l e 11 indicates the mechanical
heating portion of the heat pump will
provide 54.8 MBh for the winter
design conditions.
Step 3.
Because 54.8 MBh is less than the
building’s required heating capacity,
a supplementary heater must be
selected. 95.0 - 54.8 = 40.2 MBh
minimum heater capacity.
From Table 32, the 14.96 kW heater
has a capacity of 51,058 Btu/h.
From Table 37, the 14.96 kW heater
at 460V indicates the heater model
number is BAYHTRL415A.
This heater will be adequate to cover
the residual heat capacity needed for
the application.
Air Delivery Selection
External static pressure drop
through the air distribution system
has been calculated to be 0.77 in. of
water gauge.
From Table 31 static pressure drop
through the electric heater is 0.12 in.
of water (0.77 + 0.12 = .89 in.)
Enter Ta b l e 17 for TWE090A4 at 3000
cfm and .90 static pressure. The
standard motor at 790 RPM will give
the desired airflow.
