Features and Benefits

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 factoryinstalled 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.

Features and Benefits

Odyssey’s 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

• Outdoor Thermostat

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 factoryinstalled 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 Considerations

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.

Selection Procedure

Cooling Capacity

Step 1.

Calculate the building’s total and sensible cooling loads at design conditions.

Step 2.

Size the equipment using Tab 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

Tab le 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. Wit h 3000 cfm and 1.00 in.,

Ta b le 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 Tab le 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 le 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 Tab l e 17 for TWE090A4 at 3000 cfm and .90 static pressure. The standard motor at 790 RPM will give the desired airflow.
