Heat Pump Options
The Odyssey™ split system product line
includes heat pumps in both single and
dual compressor options.
TWA075A and TWA100A single
compressor models feature single
refrigeration circuitry lowering job
installation costs by requiring only one
set of refrigerant lines. These units are
ideal for either the low cost, new
construction jobs as well as renovation
and replacement buildings.
In addition, Odyssey models TWA155B
through TWA200B are dual compressor
units that give true standby protection; if
one compressor fails, the second will
automatically start-up. Also, the first
compressor can be serviced without
shutting down the unit since refrigerant
circuits are independent.
Dual compressors are not just for
protection, they also save energy costs.
Most buildings are designed for the peak
load requirements yet the building
usually operates at less than peak load.
During light load conditions only one
compressor functions to maintain the
space comfort thus reducing the need
for energy.
Low Ambient Cooling Operation
Each condensing unit can operate to
35° F (1.7° C) as standard. An accessory
Head Pressure Control gives you the
capability to operate to 0° F (-17.8° C). All
condensing units offer these accessories:
• Head Pressure Control
• Coil Guard Kits
• Isolators both Rubber-in-Shear and
Spring Type
• Anti-Short-Cycle Kit
• Time Delay Relay
Trane split systems have been specified
in thousands of applications and you’ll
find Odyssey will win you even more
jobs with it’s smaller, more manageable
cabinet.
Air Handlers Offer More Flexibility
Flexibility is a key to meeting changing
market requirements. Odyssey split
systems offer various compressor
options and 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 or
reconfiguration of the drain pan to make
either airflow application work. All the air
handlers feature factory installed belt
drive and ball bearing evaporator fans
with adjustable sheaves for maximum
airflow performance. The standard motor
on the TWE100A air handler will deliver
4000 cfm (1888 l/s) at 0.8” (20.32 mm)
ESP. Plus oversized motors are available
for higher static applications.
Odyssey air handler versatility is further
increased by a complete line of
accessories designed to match and
install smoothly:
• Discharge Plenum and Grille
• Return Grille
• Subbase
• Electric Heaters
• High Static Evaporator Motor
• Isolators both Rubber-in-Shear and
Spring Type
• A Full Line of Thermostats
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
condensing units to let you select the
proper match between capacity and
load. Condensing units can also be
matched with Trane built-up air handlers.
These matched systems can be quickly
engineered for specific applications.

Application
Considerations
Application of this product should be
within the catalogued airflow and
performance considerations. The System
Selection Program will simulate product
performance for a set of given
conditions. It is recommended that the
program should be run at the lowest
outdoor ambient and supply air flow
rates requiring cooling or heating
operation for a particular unit. For more
information on the System Selection
Program contact your local Trane
Representative.
Clearance Requirements
The recommended clearances identified
with unit dimensions should be
maintained to assure adequate
serviceability, maximum capacity and
peak operating efficiency. Actual
clearances that appear inadequate
should be reviewed with the local Trane
Representative.
Low Ambient Cooling
As manufactured, these units can
operate to 35° F (1.7° C) in the cooling
mode of operation. An accessory head
pressure control will allow operation to
0° F (-17.8° C) outdoor ambient. When
using these units with control systems
such as bypass changeover Variable Air
Volume, consider the requirement for a
head pressure control to allow low
ambient cooling.

Selection
Procedure
Cooling Capacity
Step 1 — Calculate the building’s total
and sensible cooling loads at design
conditions. Use the Trane calculation
form or any other standard accepted
method.
Step 2 — Size the equipment using Table
PD-1. Match the cooling loads at design
conditions.
Example: The following are the building
cooling requirements
a
Electrical Characteristics: 380-415/50/3
b
Summer Design Conditions: Entering
Evaporator Coil: 80 DB/67 WB
(27 DB/19 WB° C)
Outdoor Ambient: 95° F (35° C)
c
Total Cooling Load: 75 MBh (22kW)
d
Sensible Cooling Load: 53 MBh
(15.5 kW)
e
Airflow: 2500 cfm (1,180 l/s)
External Static Pressure: 0.77 in.
(19.6 mm) w.g. (193 Pa)
Table PD-1 shows that a TWA075A
matched with a TWE075A has a gross
cooling capacity of 82.4 MBh (24.1 kW)
and 59.5 MBh (17.4 kW) sensible capacity
at 95 DB (35° C) ambient and 2500 cfm
(1180 l/s) and 80 DB/67 WB (27 DB/19 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
0.77 in
(19.6 mm) (193 Pa)
Standard Filter
0.10 in
1 in. (25.4 mm)
(2.5 mm) (25 Pa)
Supplementary Electric Heat
0.23 in
(5.8 mm) (57 Pa)
Total Static Pressure
1.10 in
(27.9 mm) (275 Pa)
Note: The Evaporator Fan Performance
Table has included the effect of a 1 in.
(25.4 mm) filter already. Therefore, the
actual Total Static Pressure is 1.10 - 0.10 =
1.00 in. (27.9 - 2.5 = 25.4 mm)
(275 - 25 = 250 Pa)
With 2500 cfm (1180 l/s) and 1.00 inches
(250 Pa) (0.8 kW), Table 26-1 shows a 1.07
Bhp.
Note: The formula below the table can be
used to calculate Fan Motor Heat,
Constant x Motor Power =
Fan Motor Heat
3.5 x Bhp = MBh
3.5 x 1.07 = 3.75 MBh
1.375 x (kW) = kW
1.375 x 0.8 = 1.1 kW
Net Total Cooling Capacity
= 79.6 MBh – 3.75 = 75.85 MBh
= 23.3 kW - 1.1 = 22.2 kW
Net Sensible Cooling Capacity
= 57.1 MBh – 3.75 = 53.35 MBh
= 16.7 MBh - 1.1 = 15.6 kW
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 Table
PD-9 to match the heating loads at
design conditions. The following are
building heating requirements:
a
Total Heating Load: 110 MBh (32.2 kW)
b
Outdoor Ambient (Winter): 17° F
(-8.3° C) DB
c
Indoor Return Temperature: 70° F
(21.1° C) DB
d
Airflow: 2500 cfm (1180 l/s)
Table PD-9 indicates the mechanical
heating portion of the heat pump will
provide 37.5 MBh (11.0 kW) for the winter
design conditions.
Step 3 — Because 37.5 MBh (11.0 kW) is
less than the building’s required heating
capacity, a supplementary heater must
be selected. 110 - 37.5 = 72.5 MBh (32.2 -
11.0 = 21.2 kW) minimum heater capacity.
From Table PD-25, the 24.22 kW heater
has a capacity of 82,670 Btuh. From Table
34-1, the 24.22 kW heater at 400V
indicates the heater model number is
BAYHTRL435A. 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 inches (19.6 mm) of
water gauge. From Table PD-24 static
pressure drop through the electric heater
is 0.12 inches (3.0 mm) of water (0.77 +
0.12 = .89 in.) (19.6 + 3.0 = 22.6 mm).
Enter Table PD-15 for TWE090A4 at 2500
cfm (1180 l/s) and .90 static pressure. The
standard motor at 790 rpm will give the
desired airflow.
