This integrated system provides total building comfort and control. Building owners and managers not only save energy when using ICS. They have the ability to automate their facilities and the convenience of a control system interface.
Features and Benefits
Simplifying The Comfort System
Trane’s designers combined new technology and innovation to bring you more system capabilities and flexibility. Our Integrated Comfort System (ICS) with HVAC equipment is easy to use, install, commission, and service.
Everything you need to know about your self-contained VAV system is available using Tracer, Trane’s family of building automation products. Tracer is a software package that minimizes custom programming requirements and allows easy system setup and control using your personal computer. By enabling all CSC units to communicate using the LonTalk interface, transforming your heating and cooling units into a true system is made simple.
Operating data from all system components is readily available for evaluation. You can control, monitor, and service your facility—all from your personal computer. That is why all Tracer controls have been designed to be LonTalk compatible.
The IntelliPak self-contained unit, as part of Trane ICS, provides powerful maintenance monitoring, control, and reporting capabilities. Tracer places the self-contained unit in the appropriate operating mode for: system on/off, night setback, demand limiting, setpoint adjustment based on outside parameters and much more. You can monitor unit diagnostic conditions through Tracer such as: sensor failures, loss of supply airflow, and an inoperative refrigerant circuit.

Interoperability with BACnet™
The Trane Tracer SC BACnet Control Interface (BCI) for IntelliPak self-contained offers a building automation control system with outstanding interoperability benefits. BACnet, which is an industry standard, is an open, secure and reliable network communication protocol for controls, created by American Society of Heating, refrigerating and Air-Conditioning Engineers, Inc. (ASHRAE).
Interoperability allows application or project engineers to specify the best products of a given type, rather than one individual supplier's entire system. It reduces product training and installation costs by standardizing communications across products. Interoperable systems allow building managers to monitor and control IntelliPak equipment with Tracer SC controls or a 3rd party building automation system. It enables integration with many different building controls such as access/intrusion monitoring, lighting, fire and smoke devices, energy management, and a wide variety of sensors (temperature, pressure, humidity, occupancy, CO
and air velocity).

Trane Wireless Comm Interface (WCI)
The Trane® Wireless Comm Interface (WCI) is the perfect alternative to Trane’s BACnet™ wired communication links (for example, Comm links between a Tracer™ SC and a Tracer™ UC400). Minimizing communication wire used between terminal products, zone sensors, and system controllers has substantial benefits. Installation time and associated risks are reduced. Projects are completed with fewer disruptions. Future re-configurations, expansions, and upgrades are easier and more cost effective.

Trane R-410A 3-D™ Scroll Compressor

The R-410A Trane 3-D™ Scroll provides important reliability and efficiency benefits inherent in its design. The 3-D™ Scroll allows the orbiting scrolls to touch in all three dimensions, forming a completely enclosed compression chamber which leads to increased efficiency. In addition, the orbiting scrolls only touch with enough force to create a seal, eliminating wear between the scroll involutes. The fixed and orbiting scrolls are made of high strength cast iron which results in less thermal distortion and minimal leakage. In addition, improved part isolation provides reduced compressor sound levels compared to previous designs.
Features listed below optimize the compressor design and performance:
• Optimized scroll profile
• Heat shield protection to reduce heat transfer between discharge and suction gas
• Improved sealing between high side and low side
Additional features are incorporated in the compressor design for greater reliability:
• Patented design motor cap for improved motor cooling
• Improved bearing alignment
• Improved resistance to dry start-up
• Oil sight glass for evaluating proper oil levels
Features and Benefits
Low Torque Variation
The 3-D™ Scroll has a very smooth compression cycle, imposing very little stress on the motor and resulting in greater reliability. Low torque variation reduces noise and vibration.
Suction Gas Cooled Motor
Compressor motor efficiency and reliability is further optimized with the latest scroll design. The patented motor cap directs suction gas over the motor, resulting in cooler motor temperatures for longer life and better efficiency.
Proven Design through Testing and Research
The new R-410A 3-D™ Scroll compressor is the next generation of reliable Trane 3-D™ Scroll compressors provided by Trane, the leader in scroll compressor technology.

Self-Contained Acoustical Recommendations

Successful acoustical results are dependent on many system design factors.
Following are general acoustical recommendations. For more information, or if there is concern about a particular installation, contact a professional acoustical consultant.
Location and Orientation of the Mechanical Equipment Room
Locate the equipment room adjacent to stairwells, utility rooms, electrical closets, and rest rooms if possible (See figure below). This minimizes the acoustic effects and risk of workmanship or installation errors. Place the discharge and return air ductwork over these less acoustically sensitive areas, using vertical or horizontal fresh air shafts. Consult code requirements for fresh air and smoke purge constraints.
Return Air Ductwork
Duct the return air into the mechanical equipment room. Connect ductwork to the unit if local code dictates. The return air ductwork must have an elbow inside the equipment room. This elbow will reduce sound transmissions through the return duct. Extend the ductwork from the elbow far enough to block the “line of sight” to the exterior of the equipment room. Use a minimum ductwork length of 15 feet to the equipment room exterior. Line the duct with two-inch, three-pound density insulation. Use multiple, small return ducts for better acoustical performance to the occupied space.
Supply Air Ductwork
Insulate the supply air duct with two-inch, three-pound density insulation. Extend this lining at least 15 feet out from the equipment room wall, keeping the duct aspect ratio as small as possible. Minimize large flat panels since they transmit sound. In addition, small aspect ratios will minimize potential “oil canning” of the duct due to flow turbulence.
The flexible horizontal discharge plenum option helps avoid complicated ductwork transitions. Ductwork turning vanes typically improve pressure drop but degrade acoustical performance.
Recommended Maximum Air Velocities
The maximum recommended velocity for the discharge air duct is 2,000 fpm. The maximum recommended velocity for the return air duct is 1,000 fpm. Limit air velocities below these operating points to minimize the risk of flow turbulence that causes regenerated noise. Using round supply duct and static regain allows maximum discharge air velocities up to 3,000 fpm. Lining round supply duct also substantially lowers frequency noise attenuation. However, flow regenerated noise potential increases dramatically at air velocities over 3000 fpm.
Figure 2. Equipment room location and orientation
Application Considerations
Equipment Room Construction Options
The preferred equipment room wall construction is concrete block. If this is not feasible then a double stud offset wall is suggested (See figure). This removes physical contact that would transmit sound through the equipment room wall to the occupied space. Interweave fiberglass insulation between the wall studs. Use two layers of sheetrock on each side of the wall.
Workmanship details are critical to acoustical performance. Seal all wall and floor penetrations by the ductwork, water piping, and equipment room access doors with a flexible material such as caulk and/or gasketing to stop noise and air leaks.
Locate the equipment room door away from acoustically sensitive areas like conference rooms. The door should swing out of the equipment room, if possible, so that the low pressure in the equipment room pulls the door in to help maintain a tight seal.
Equipment Options
The flexible horizontal discharge plenum allows multiple tested outlet options. This minimizes the risk of acoustic and/or pressure drop problems by avoiding complex transitions close to the fan discharge.
Static Pressure Versus Acoustics
Design the system to minimize the total static pressure required from the self-contained unit fan. Typically a change in static pressure of only 0.5 inches can reduce NC level by approximately 2 or 3 in the occupied space.

Isolation Recommendations

Unit
The Signature Series unit fan and compressors are internally isolated. Therefore, external isolation is not required. Consult a vibration specialist before considering external or double vibration isolation.
Ductwork
Design duct connections to the unit using a flexible material. Consult local codes for approved flexible duct material to prevent fire hazard potential.
Piping Connections
Rubber isolator connectors are recommended for condenser piping to prevent vibration transmission to or from the building plumbing. The Signature Series self-contained unit is internally isolated and does not require additional isolation. However, ensure proper system vibration isolation design prevents vibration transmission from the building plumbing to the unit. Also be sure to properly isolate the drain line.

Condenser Water Piping

Piping Location and Arrangement
Provide at least 24 inches of clearance between the piping and the unit for service. Place the risers away from the side of the unit if possible. Be sure to allow sufficient space for valves and unions between the piping and the self-contained unit. Lay out condenser piping in reverse returns to help balance the system. This is accomplished by equalizing the supply and return pipe length. Multi-
PKG-PRC002U-EN 11
Application Considerations
story buildings may use a direct return system with balancing valves at each floor. Install all heat exchangers and most cooling tower piping below the sump operating water level to prevent overflow during unit and/or system shut down.
Recommended Pump Location
Locate pump downstream of the cooling tower and upstream of the self-contained unit. This provides smoother and more stable unit operation.
When the tower and pump are both roof mounted, be sure to provide the necessary net positive suction head pressure to prevent cavitation. Raise the tower or submerge the pump in a sump to provide positive suction. To prevent an on-line pump failure, use a standby pump to avoid a complete system shutdown.
Several partial capacity pumps or variable speed pumps may be used. Review the economics of these alternate pumping options.
Strainers and Water Treatment
Water strainers are required at the unit inlet to eliminate potential unit damage from dirty water. Specify a water basket-type strainer to avoid an incorrect stream strainer application. Untreated or poorly treated water may result in equipment damage. Consult a water treatment specialist for treatment recommendations.
Isolation Valves
Install isolation valves at each unit before the strainer and after the condenser. This allows periodic servicing of the unit or strainer while allowing other units in the system to remain in operation.
Pressure Gauges
Install pressure gauges on the inlet and outlet of the self-contained unit. Select the gauge’s scale so that the unit design operating point is approximately mid-scale.
Thermometers
Install thermometers on the condenser water inlet and outlet lines to each unit for system analysis. Trane Company recommends using a thermometer temperature range of 40 to 140°F, using a 2°F temperature increment.
Drains
The unit condensate drain is internally trapped to offset the pressure differential that exists during fan operation. Install a trapped drain in the low point of the mechanical equipment room floor to collect water from cleaning operations.
Condensing Pressure Control (Water-Cooled condensers)
Often cold condensing water applications between 35°F and 54°F require a condensing pressure control valve. Any unit with variable-flow waterside valves can modulate water flow to maintain a user defined condensing temperature. However, to utilize this feature, the building water system must be capable of operating at reduced water flow rates through the self-contained units. It is imperative to install variable volume pumps or an external bypass in the water distribution system.
Waterside Economizer Flow Control
Units equipped with waterside economizer control valves can be set up for variable or constant water flow.
Use constant water flow setup on water systems that are not capable of unloading water supply to the unit. The economizer and condenser valves will operate in complement to one another to provide continuous water flow.
Use variable water flow setup with water flow systems that can take advantage of pump unloading for energy savings. Since non-cooling operation restricts water flow during part load economizing or condensing temperature control, it is imperative to install variable volume pumps or an external bypass in the water distribution system.
Application Considerations

Free Cooling Opportunities and Alternatives

Free cooling is available with either the airside or waterside economizer options.
Waterside Economizer
The waterside economizer substantially reduces the compressor energy requirements because it uses the cooling water before it enters the condensers. Additional equipment room space is not required since the coils are contained within the overall unit dimensions.
Disadvantages include higher airside pressure drop and a higher head on condenser water pumps.
The coils may be mechanically cleanable (optional) for ease in maintenance versus expensive and difficult chemical cleaning methods.
Airside Economizer
The airside economizer substantially reduces compressor, cooling tower, and condenser water pump energy requirements using outside air for free cooling. It also reduces tower make up water needs and related water treatment.
Disadvantages include building requirements that locate the mechanical room and self-contained unit toward an exterior wall to minimize ductwork, building barometric control, or additional air shafts. Also, airside economizers require additional mechanical room space.

Unit Operating Limits

Airflow
The minimum recommended airflow for proper VAV system staging and temperature control is 35 percent of nominal design airflow. Adjusting VAV boxes with the appropriate minimum settings will prevent the self-contained unit from operating in a surge condition at airflows below this point. Continuous operation in a surge condition can cause fan failure. Reference General Data Tables on
Table 1, p. 20 for minimum airflow conditions.
PKG-PRC002U-EN 13
Application Considerations
Signature Series self-contained units use fixed pitch sheaves. Adjust air balancing by obtaining alternate fixed pitch sheave selections from the local Trane sales office.
Water Flow
Use 3 gpm/ton for optimum unit capacity and efficiency. Use 2.5 or 2 gpm/ton to reduce pump energy, cooling tower and piping costs. However, these reduced water flows may impact unit capacity and efficiency by one or two percent. Consult General Data Tables on pages 17-20 for unit specific water flow ranges.

Remote Air-Cooled Condenser

Unit Location
Unobstructed condenser airflow is essential to maintaining capacity and operating efficiency. When determining unit placement, give careful consideration to assure sufficient airflow across the condenser coils. Avoid these two detrimental conditions: warm air recirculation and coil starvation.
Both warm air recirculation and coil starvation cause reductions in unit efficiency and capacity because of the higher head pressure associated with them. In more severe cases, nuisance unit shutdowns will result from excessive head pressures.
Clearance
Ensure vertical condenser air discharge is unobstructed. While it is difficult to predict the degree of warm air recirculation, a unit installed with a ceiling or other obstruction above it will experience a capacity reduction that will reduce the maximum ambient operation limit. Nuisance high head pressure trips may also occur.
The coil inlet must also be unobstructed. A unit installed closer than the minimum recommended distance to a wall or other vertical riser will experience a combination of coil starvation and warm air recirculation. This may result in unit capacity and efficiency reductions, as well as possible excessive head pressures. Reference the service clearance section on page 111 for recommended lateral distances.
Ambient Limitations
Standard ambient control allows operation down to 45°F with cycling of condenser fans. Units with the low ambient option are capable of starting and operating in ambient temperatures down to 0°F. Optional low ambient units use a condenser fan damper arrangement that controls condenser capacity by modulating damper airflow in response to saturated condenser temperature.
Maximum ambient operating temperature of a standard condenser is 115°F. Operation at design ambient above 115°F can result in excessive head pressures. For applications above 115°F, contact the local Trane sales office.

Selection Procedure

Following is a sample selection for a standard applied water-cooled self-contained at particular operating conditions. Use Trane Official Product Selection System, TOPSS™, for making all final selections or contact your local Trane representative.
Unit Capacities
1. Determine entering air temperature dry bulb and wet bulb and entering water temperature.
2. See chapter “Performance Data,” p. 27 to find gross total and sensible capacity that best meets capacity requirements.
3. Apply the cfm correction factors from the capacity correction factor Ta bl e 13, p. 37 to determine gross total and gross sensible capacities at desired cfm.
4. Multiply condenser water delta T by the total capacity cfm correction factor to determine new condenser water delta T.
5. Using design cfm, determine static air pressure drops for accessories from the air pressure drop Charts external supply and return static air pressure drops. Use the total air pressure drop to determine rpm and brake horsepower requirements from the appropriate fan curve. Note: The fan curves include refrigerant coil and internal cabinet static loses.
6. Calculate supply fan motor heat by using the following equation:
Fan motor heat (MBh) = 2.8 x fan motor brake horsepower
7. Determine net total capacity and net sensible capacity by subtracting fan motor heat from gross total capacity and gross sensible capacity.
8. Refer to Trane psychometric chart to determine leaving air temperatures.
Figure 1, p. 27 through Figure 21, p. 33. Add accessory static pressure drops to
Waterside Economizer Capacity
After determining that the unit will meet the required mechanical cooling capacity, determine the waterside economizer capacity by referring to the appropriate two-row (low capacity) or four-row (high capacity) waterside economizer capacity found in one of Table 15, p. 38 through Ta b le 48 ,
p. 72.
9. Determine entering air temperature dry bulb and wet bulb, condenser water flow (gpm), and economizer entering water temperature.
10. Refer to the appropriate waterside economizer table to find gross total and sensible capacity and the leaving water temperature.
11. Apply the cfm correction factor for the waterside economizer from the appropriate table to determine the gross total and sensible capacities at the desired cfm.
12. Multiply the condenser water delta T by the total capacity cfm correction factor to determine the new delta T.
13. Calculate supply fan motor heat by using the following equation:
Fan motor heat (MBh) = 2.8 x fan motor brake horsepower
14. Determine net total and sensible capacity by subtracting fan motor heat from gross total and sensible capacity.
15. Refer to the Trane psychometric chart to determine leaving air temperatures.
Selection Example
Design Conditions
Total gross capacity required = 420 MBh = 35.2 Tons
Total sensible capacity required = 315 MBh
Entering air temperature = 80/67°F
PKG-PRC002U-EN 15
Selection Procedure
Unit includes:
Unit Selection
Tentatively select a 35 ton unit: Model SCWF 35.
Refer to Table 26, p. 49 to obtain gross total and sensible unit capacities, and gpm at the design conditions:
Since the design cfm is greater than the nominal cfm, adjust the capacities and condenser water delta T to reflect the higher cfm: design cfm 14840 = +6% of nom. Cfm nominal 14000 cfm
Refer to Tab l e 1 3 , p. 37 to obtain the capacity correction factors for +6% of nominal cfm:
Multiply the capacities by the correction factors:
The SCWF 35 meets the total and sensible design requirements.
Multiply the delta T of 10.1°F by the cooling capacity correction factor of 1.009 to obtain new delta T of 10.19°F and add this to the entering water temperature to obtain the actual leaving water temperature of 95.19°F.
Entering water temperature = 85°F
Water flow rate = 105 gpm
Airflow = 14840 cfm at 2.5-inch duct static pressure
• Constant Volume
• Waterside economizer
• Medium velocity throwaway filters
Total capacity = 432.0 MBh
Sensible capacity = 329.0 MBh
Leaving water temperature = 95.1°F
Cooling capacity multiplier = 1.009
Sensible capacity multiplier = 1.027
• 432 MBh x 1.009 = 435.89 MBh
• 329 MBh x 1.027 = 337.88 MBh

Airside Pressure Drops

The dotted line on construction filters indicates cfm where face velocity exceeds manufacturer’s recommended maximum of 300 fpm. After startup, construction filters must be replaced with medium velocity or high velocity filters.
Air pressure drops through electric heat is 0.5 inches WC.
See “Discharge Plenum,” p. 30 for pressure drop through flexible horizontal discharge plenum and
“Heating Coils,” p. 29 for pressure drop through heating coils.
For 4-inch cartridge filters, air pressure drops must be added to the external static pressure design point.
