2.0 - Introduction The Bureau of Reclamation, Upper Colorado Region, Brackish Groundwater National Desalination Research Facility, (Reclamation) has a need to repair their 10-ton Trane Air Handling Unit (AHU). Leaks have been identified in the evaporative coil and 22 lbs of refrigerant were added November 21, 2024. The expected repairs required to get the unit functional include removing and replacing the evaporator coil, thermal expansion valves, and the filter dryers. The remaining refrigerant must be captured and reused; if needed supplemental R- 22 refrigerant will be required. The contractor must be licensed to perform work on HVAC units, able to recover, add, and purchase R22 refrigerant, and capable of performing the work within a reasonable timeframe.

2.1 – Location and Hours of Operations The Reclamation facility is located at 500 La Velle Road, Alamogordo, NM 88310.

Reclamation’s standard business hours are Monday through Friday from 8:00 AM to 4:30 PM MST except federal holidays.

2.2 – Site Visit Reclamation can host a site visit if requested by prospective bidder.

The current period of performance for this Statement of Work (SOW) is 60 days after notice to proceed, however repairs are requested as soon as possible to lower the amount of additional refrigerant needed. Adjustments to the schedule will be considered if weather will impact quality and safety during the project activities/tasks. An option for purchasing additional refrigerant is included, as it is possible that new R-22 refrigerant will be needed by the time work starts.

2.3 - Background

The Brackish Groundwater National Desalination Research Facility (BGNDRF) is a federal facility that operates under the United States Department of Interior, Bureau of Reclamation

(Reclamation). Established by an Act of Congress, the facility mission is to promote sustainable advanced water treatment research and technology development for inland brackish groundwater sources and, specifically, to conduct research for the development of cost-effective, robust desalination and alternative energy technologies that produce sustainable new supplies of water and power for municipal, industrial, agricultural, and environmental purposes

2.4 – North American Industry Classification System (NAICS) The NAICS for this work is 238220 - Heating, Ventilation, and Air Conditioning (HVAC) contractors.

2.5 - Purpose The purpose is to protect and maintain the federally owned asset. The facility is equipped with a Trane Split System, with a 10-ton Trane condenser installed at ground level outside the building and a 10-ton Trane air handling unit installed inside the building at the mezzanine level. The part number for the AHU is TWE120B00EL and the associated condenser is TTA120B400EA; both have a Manufacturer Date of 10/2006.

The condenser and evaporator were both inspected in November 2024 by an Alamogordo-area HVAC company. Using a dye pack in the refrigerant and an inspection two weeks after new refrigerant was added, leaks were found in the evaporator coil. The service technician suggested replacing the evaporator coil unit, thermal expansion valves, and refrigerant filter dryers.

Condensing Unit Options

The Odyssey split system product line includes condensing units in single, unloading and dual compressor 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 the low cost, new construction jobs as well as renovation and replacement buildings.

Equally important, Odyssey offers a single refrigerant circuit/capacity unloading option in 10 and 15 ton condensing units. These unloading units feature dual manifolded scroll compressors. They offer an excellent opportunity for both new construction and replacement jobs with two stages of capacity modulation and a single refrigeration circuit.

In addition, Odyssey includes a 10, 12½, 15 and 20-ton dual compressor unit 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 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. For instance, the EER of the 10-ton unit at ARI conditions is 9.5 and at part load conditions it is 10.3.

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. This lighter, compact design will save time and money for rigging and installation. And the compactness will permit Trane’s unit to replace almost any unit — effortlessly.

Low Ambient Cooling Operation

Each condensing unit can operate to 35°F (1.6°C) as standard. An accessory Head Pressure Control gives you the capability to operate to 0°F (-18°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

• Black Epoxy Coated Coil

Air Handlers Offer More Flexibility

Flexibility is a key to meeting changing market requirements. Odyssey split systems offer not only various compressor options 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.

These air handlers have a double sloped condensate drain pan that allows for either airflow configuration. And 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 (6796 m3/h) at 1.4” ESP (350 Pa). Additionally, oversized motors are available for higher static applications.

5SS-PRC004-EN

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. Heat pumps can also be matched with Trane built-up air handlers. Also, these matched systems can be quickly engineered for specific applications using Trane’s computerized selection and load programs.

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

• Outdoor Thermostat

Odyssey Lowers Installation Costs

Your installation costs are reduced with Odyssey. Both outdoor units and air handlers are factory packaged and assembled so jobsite installation is quick and easy. You get a complete unit with all the components, controls and the internal wiring factory ready for a smooth jobsite start-up.

Unlike some competitive models the following components are factory-installed in Trane air handlers:

l Single Point Power Entry l Blower wheel and housing l Evaporator motor with sheaves and pulleys l Low Voltage Terminal Board l Transformer (Most Models) l Contactor l Fan relay l DX Coil with complete refrigeration circuitry l 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

Low Ambient Cooling

As manufactured, these units can operate to 35° F (1.6°F) in the cooling mode of operation. An accessory head pressure control will allow operation to 0° F (-18°C) 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.

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 which appear inadequate should be reviewed with the 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 addition of kit. See unit installer's guide.

Selection Procedure

TTA 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: 460/60/3 B Summer Design Conditions:

Entering Evaporator Coil:

80° F (26.6° C) DB/67° F (19.4° C) WB

Outdoor Ambient: 95° F (35° C)

C Total Cooling Load: 88 MBh (25KW) D Sensible Cooling Load: 64 MBh (19 KW) E Airflow: 3000 cfm (5097 m3/hr)

External Static Pressure:

0.73 in. w.g. (183 Pa)

Table PD-1 shows that a TTA090A4 matched with a TWE090A has a gross cooling capacity of 89.9 MBh (26 kW) and 64.3 MBh (19 kW) sensible capacity at 95° F (35° C) DB ambient and 3000 cfm (5097 m3/hr) with 80° F (26.6° C) DB/ 67° F (19.4° C) 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 (191 Pa) Standard Filter 1 in. 0.10 in (25 Pa) Supplementary Electric Heat 0.23 in (57 Pa) Total Static Pressure 1.10 in (272 Pa) 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 in. – 0.10 in. = 1.00

in. (275 Pa - 25 Pa = 250 Pa).

With 3000 cfm (5097 m3/hr) and 1.00 inches (250 Pa), Table PD-25 shows a 1.17 Bhp (.87 kW).

Note: The formula below the table can be used to calculate Fan Motor Heat,

3.5 X Bhp = MBh

(1.375 x kW = kW)

3.5 X 1.17 = 4.10 MBh

(1.375 x kW = 1.2 kW)

Net Total Cooling Capacity = 89.9 MBh - 4.10 MBh = 85.80 MBh (= 26 kW - 1.2 kW = 25 kW)

Net Sensible Cooling Capacity = 64.3 MBh - 4.10 MBh = 60.20 MBh (=19 kW - 1.2 kW = 18 kW)

Heating Capacity Step 1 — Calculate the building heating load using the Trane calculation form or other standard accepted method.

Step 2 — Size the system heating capacity to match the calculated building heating load. The following are building heating requirements:

A Total Heating Load at 97.0 MBh (28 kW) B 3000 cfm (5097 m3/hr) C Electric Supplementary Heaters

From Table PD-42, the 34.88 kW heater has a capacity of 119,045 Btuh. From Table ED-5, the 34.88 kW at 460v indicates the heater model number is BAYHTRL435A. This heater will adequately cover the building’s heating requirement.

Air Delivery Selection External static pressure drop through the air distribution system has been calculated to be 0.77 inches of water gauge (193 Pa). From Table PD-41 static pressure drop through the electric heater is 0.23 inches of water (0.77 in. + 0.23 in.

= 1.00 in. (193 Pa + 58 Pa = 250 Pa). Enter Table PD-25 for TWE090A4 at 3000 cfm (5097 m3/hr) and 1.00” (250 Pa) static pressure. The standard motor at 821 RPM will give the desired airflow.

NOTES:

1. Dry coil condition. Total Gross Cooling Capacity (MBh) shown to the left is not applicable. In this case the Sensible Heat Capacity (SHC) is the total capacity.

All capacities shown are gross and have not considered indoor fan heat.

To obtain net cooling capacities subtract indoor fan heat.

MBH = Total Gross Cooling Capacity SHC = Sensible Heat Capacity
