Integrated
Rooftop
Systems:
Profitable,
Simple
Trane integrated rooftop systems make design and installation of building management systems cost effective and easy.Trane offers two choices for building management controls:Tracer Building Automation System with a Trane Control Interface (TCI) orTracer with LonTalk® Communication Interface (LCI).
Integrated Comfort with TraneTracer™ TCI
TheTracerTCI Integrated Comfort™ System (ICS) improves job profit and increases job control by combiningTrane rooftop units with theTraneTracer building management system.This integrated system provides total building comfort and control. Some of the primary motivations for building owners/managers in deciding to purchase a HVAC controls system is energy savings, cost control, and the convenience of facility automation.
Simplifying the Comfort System
Trane’s technology and innovation brings more capabilities, more flexibility, and at the same time, offers equipment and systems that are easy to use, easy to install, commission, and service.The TracerTCI Integrated Comfort system saves time and money by simplifying system design and system installation. When used withTrane’s DDC/VAV boxes (orVariTrane™), system balancing almost goes away because eachVAV box is commission and tested before it leaves the factory. All the status information and editing data from the
6
rooftop units,VAV boxes, lighting, exhaust and other auxiliary equipment is available fromTracerTCI for control, monitoring and service support of your facility.Tracer, a family of building automation products fromTrane, is designed with robust, application specific software packages to minimize custom programming requirements and enable system setup and control through simple editing of parameters in the standard applications software. Should you select an Integrated Comfort system for your facility, the accountability for equipment, automation and controls isTrane’s, Trane’s, andTrane’s!
The IntelliPak rooftop, as a part of an Integrated Comfort system, provides powerful maintenance monitoring, control and reporting capabilities.The Tracer places the rooftop in the appropriate operating mode for operation for: system on/off, night setback, demand limiting , setpoint adjustment based on outside parameters and much more. Up to 56 different unit diagnostic conditions can be monitored throughTracer to let you know about things like: sensor failures, loss of supply airflow, and a compressor trip out. Further, the addition of Building Management Network software offers remote scanning, automatic receipt of alarms, and easy dial-up access to over 100 variousTracer sites across town or across the country.

Interoperability with LonTalk
TheTraneTracer LonTalk Control Interface (LCI) for IntelliPak offers a building automation control system with outstanding interoperability benefits.
LonTalk, which is an industry standard, is an open, secure and reliable network communication protocol for controls, created by Echelon Corporation and adopted by the LonMark Interoperability Association. It has been adopted by several standards, such as: EIA-709.1, the
RT-PRC010-EN
Features and
Benefits
Electronic Industries Alliance (EIA) Control Network Protocol Specification and ANSI/ASHRAE 135, part of the American Society of Heating, Refrigeration, and Air-Conditioning Engineer’s BACnet control standard for buildings.
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 aTrane Tracer Summit 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, light, humidity, occupancy, CO2 and air velocity). For more information on LonMark, visit www.lonmark.org or Echelon, www.echelon.com.
Optimum
Building Comfort Control
The modular control design of the UCM allows for greater application flexibility. Customers can order exactly the options required for the job, rather than one large control package. Unit features are distributed among multiple field replaceable printed circuit boards.The Trane UCM can be set up to operate under one of three control applications:
1stand-alone
2interface withTrane’sTracer™ building management system
3interface with a generic (non-Trane) building management system. All setup parameters are preset from the factory, requiring less start-up time during installation.
The unit mounted Human Interface and the Remote Human Interface Panels’ functions are identical, except for the Service mode is not available on the Remote Human Interface Panel.This common interface feature requires less time for building maintenance personnel to learn to interact with the unit. All of the rooftop’s control parameters are adjustable and can be set up through the Remote Human Interface Panel such as, but not limited to: system on/off, demand limiting type, night setback setpoints, and many other setpoints. No potentiometers are required for setpoint adjustment, all adjustments are done through the Remote Human Interface keypad. Also up to 56 different rooftop diagnostic points can be monitored through the human interfaces such as: sensor failures, loss of supply airflow, and compressor trip. No special tools are required for servicing of the unit. All diagnostic displays are available in clear English at the Remote Human Interface and will be held in memory, so that the operator/servicer can diagnose the root cause of failures.
Statitrac™ Direct Space
Building Pressurization Control
Trane’s Statitrac™ control is a highly accurate and efficient method of maintaining building pressure control with a large rooftop air conditioner.
The efficiency is achieved with a 100 percent modulating exhaust system with two forward-curved fans with modulating discharge dampers that operate only when needed, compared to some systems that operate continually. And most of the operating hours of the 100 percent modulating exhaust system are at part load, saving more energy. Trane’s Statitrac, with the 100 percent modulating exhaust system, provides comfort and economy for buildings with large rooftop air conditioning systems.
Statitrac control is simple!The space pressure control turns the exhaust fans on and off as required and modulates exhaust dampers to maintain space pressure within the space pressure dead band. Using the unit mounted Human Interface Panel you can
1)adjust space pressure setpoint
2)adjust space pressure dead band
3)measure and read building space pressure.The modulating exhaust system maintains the desired building pressure, saving energy while keeping the building at the right pressure. Proper building pressurization eliminates annoying door whistling, doors standing open, and odors from other zones.
The Statitrac™ direct space building control sequence will be maintained when a variable frequency drive is used.
FansWith Inlet GuideVanes
Trane’s forward curved fans (20 through 75 tons) and air foil fans (90 through 130 tons) with inlet guide vanes pre-rotate the air in the direction of the fan wheel, decreasing static pressure and horsepower, essentially unloading the fan wheel.The unloading characteristics result in superior part load performance.
Variable Frequency Drives (VFD)
Variable Frequency Drives are factory installed and tested to provide supply/ exhaust fan motor speed modulation.
VFD’s, as compared to inlet guide vanes or discharge dampers, are quieter, more efficient, and are eligible for utility rebates.TheVFD’s are available with or without a bypass option. Bypass control will simply provide full nominal airflow in the event of drive failure.

Trane 3-D™ Scroll Compressor
Simple Design with 70% Fewer Parts
Fewer parts than an equal capacity reciprocating compressor means significant reliability and efficiency benefits.The single orbiting scroll eliminates the need for pistons, connecting rods, wrist pins and valves. Fewer parts lead to increased reliability. Fewer moving parts, less rotating mass and less internal friction means greater efficiency than reciprocating compressors.
TheTrane 3-D Scroll provides important reliability and efficiency benefits.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; there is no wear between the scroll plates.The fixed and orbiting scrolls are made of high strength cast iron which results in less thermal distortion, less leakage, and higher efficiencies. The most outstanding feature of the 3-D Scroll compressor is that slugging will not cause failure. In a reciprocating compressor, however, the liquid or dirt can cause serious damage.
LowTorqueVariation
The 3-D Scroll compressor has a very smooth compression cycle; torque variations are only 30 percent of that produced by a reciprocating compressor. This means that the scroll compressor imposes very little stress on the motor 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. Cool suction gas keeps the motor cooler for longer life and better efficiency.

Application
Considerations
EXHAUST AIR OPTIONS
When is it necessary to provide building exhaust?Whenever an outdoor air economizer is used, a building generally requires an exhaust system.The purpose of the exhaust system is to exhaust the proper amount of air to prevent over or underpressurization of the building.The goal is to exhaust approximately 10 percent less air than the amount of outside air going into the building.This maintains a slightly positive building pressure.
A building may have all or part of its exhaust system in the rooftop unit. Often, a building provides exhaust external to the air conditioning equipment.This external exhaust must be considered when selecting the rooftop exhaust system.
IntelliPak™ Rooftop units offer four types of exhaust systems:
1
100 percent modulating exhaust with Statitrac™ direct space sensing building pressurization control (with or without variable frequency drives).
2
100 percent modulating exhaust without Statitrac.
3
50 percent power exhaust.
4
Barometric relief dampers.
Application Recommendations
1
100 percent modulating exhaust with Statitrac™ control
For both CV andVAV rooftops, the 100 percent modulating exhaust discharge dampers (orVFD) are modulated in response to building pressure. A differential pressure control system, called Statitrac™, uses a differential pressure transducer to compare indoor building pressure to atmospheric pressure.The FC exhaust fan is turned on when required to lower building static pressure to setpoint.The Statitrac control system then modulates the discharge dampers (orVFD) to control the building pressure to within the adjustable, specified dead band that is set at the Human Interface Panel.
Advantages of the Statitrac™ 100 percent modulating exhaust system are:
a
The exhaust fan runs only when needed to lower building static pressure.
b
Statitrac compensates for pressure variations within the building from remote exhaust fans and makeup air units.
c
The exhaust fan discharges in a single direction resulting in more efficient fan operation compared to return fan systems.
RT-PRC010-EN
d
Because discharge dampers modulate the airflow, the exhaust fan may be running unloaded whenever the economizer dampers are less than 100 percent open.
With an exhaust fan system, the supply fan must be sized to pull the return air back to the unit through the return system during non-economizer operation. However, a supply fan can typically overcome return duct losses more efficiently than a return air fan system. Essentially, one large fan by itself is normally more efficient than two fans in series because of only one drive loss not two as with return air systems.
The reason for either a return air fan or an exhaust fan is to control building pressure.TheTrane 100 percent modulating exhaust system with Statitrac does a better job controlling building pressure than return fans simply because 100 percent modulating exhaust discharge dampers (orVFD) are controlled directly from building pressure, rather than from an indirect indicator of building pressure such as outdoor air damper position.
The 100 percent modulating exhaust system with Statitrac may be used on any rooftop application that has an outdoor air economizer. However, when most exhaust is handled external to the rooftop or when building pressure is not critical, one of the other less expensive methods of exhaust may be used.

Application
Considerations
2
100 Percent Exhaust System
Competitive rooftops use a return air fan system for controlling the amount of exhaust air during economizer operation.The return fan is in series with the supply fan and must operate whenever the supply fan is operating. During economizer operation, the economizer outdoor air dampers control the position of the return and exhaust air dampers, to exhaust the proper amount of air.The disadvantage of a return air fan is that it runs continuously, versus an exhaust fan system which runs only when needed to lower or maintain building static pressure. Also, the return fan must discharge air in two directions, through the return air dampers and/or exhaust air dampers, resulting in less efficient operation compared to an exhaust fan.
The IntelliPak™ Rooftop unit offers modulating 100 percent exhaust system. This fan system has performance capabilities equal to the supply fan.The FC exhaust fans are started by the
economizer’s outdoor air damper position and the exhaust dampers track the economizer outdoor air damper position.The amount of air exhausted by this fan is controlled by modulating discharge dampers at the fan outlet.The discharge damper position is controlled by a signal that varies with the position of the economizer dampers.When the exhaust fans start, the modulating discharge dampers are fully closed, and exhaust airflow is 15 to 20 percent of total exhaust capabilities.
3
50 Percent Exhaust System
The 50 percent exhaust system is a single FC exhaust fan with half the airmoving capabilities of the supply fan system.The experience ofTheTrane Company is that a non-modulating exhaust system selected for 40 to 50 percent of nominal supply CFM can be applied successfully.
The 50 percent exhaust system generally should not be selected for more than 40 to 50 percent of design supply airflow. Since it is an on/off nonmodulating
Figure AC-1 — PlanView of Modulating 100 Percent Exhaust System
system, it does not vary exhaust CFM with the amount of outside air entering the building.Therefore, if selected for more than 40 to 50 percent of supply airflow, the building may become underpressurized when economizer operation is allowing lesser amounts of outdoor air into the building. If, however, building pressure is not of a critical nature, the non-modulating exhaust system may be sized for more than 50 percent of design supply airflow.
4
Barometric Relief Dampers
Barometric relief dampers consist of gravity dampers which open with increased building pressure. As the building pressure increases, the pressure in the unit return section also increases, opening the dampers and relieving air. Barometric relief may be used to provide relief for single story buildings with no return ductwork and exhaust requirements less than 25 percent.

Application
Considerations
Horizontal Discharge
The typical rooftop installation has both the supply and return air paths routed through the roof curb and building roof. However, many rooftop installations require horizontal supply and/or return from the rooftop because of a building’s unique design or for acoustic considerations.
Trane has two ways to accomplish horizontal supply and/or return.The first applies to all IntelliPak™ Rooftop units. Special field supplied curbs are installed that use the unit’s standard discharge and return openings.The supply and return air is routed through the curb to horizontal openings on the sides of the curb.The second method available for horizontal supply and return applies to
20 - 75 tons SXHF, SFHF, SLHF, SSHF, and
90 - 130 tons SXHG, SLHG and SSHG design units ONLY. With this method the standard discharge and return openings are blocked in the field. Access panels are removed as indicated in Figures AC-1 and AC-2.These openings are used for the discharge and return. No special curb is needed.
SXHF, SFHF, SLHF, SSHF Units
Figure AC-1 is a simplified sketch of the rooftop showing which panels can be used for horizontal supply and/or return. To supply air horizontally, the panels that normally house the heat accessory controls (Panel A) and the gas heat barometric dampers (Panel B) can be removed and either of the openings
Figure AC-2 Horizontal Discharge Panel Dimensions — 20 - 75Tons SXHF, SFHF, SLHF, SSHF Units
Note: Cannot remove Panel A for horizontal discharge on SFHF, SLHF, SSHF Units.
used as a unit discharge (see note 1).To return air horizontally, the exhaust fan access door (Panel C) can be removed and used as a return opening.Tables AC- 1, 2 and 3 show dimensions for those panels.
Horizontal Discharge on SXHF, SFHF, SLHF and SSHF Rooftops (20 to 75 tons)
The SXHF (extended casing cooling only), SFHF (gas heat), SSHF (steam heat) and SLHF (hot water heat) rooftops can be field modified to supply and return air horizontally without the use of a horizontal supply/return curb.
To supply air horizontally on SXHF only, the panels that normally house the heat accessory controls (Panel A) and the gas heat barometric dampers (Panel B) can be removed and either of the openings used as a unit discharge.To return air horizontally, the exhaust fan access door (Panel C) can be removed and used as a return opening.
1.For horizontal discharge on SFHF, SLHF and SSHF units, only the Panel B can be removed. Panel A cannot be used due to the location of the heating coils.
2.For horizontal discharge on SFHF (gas heat) models, the block off under the heater must be removed. After removal, a support must be added for the drain tube.
3.Supply and Return Base openings must be covered when converting to a horizontal configuration.

Application
Considerations
Figure AC-3 is a simplified sketch showing which panels can be used for horizontal supply and/or return. On 90 to 130 ton units, only one side of the extended casing may be used for horizontal supply because of the location of the unit control panel.There are, however, on SXHF models two panels (Panels A) on the side opposite the control box which can be removed along with the vertical support which separates the two. Removal of the vertical support is optional, but will ensure maximum airflow. On SLHG, SSHG models only one of the Panel A’s may be used for horizontal supply
because of the location of the heating coil. Horizontal return is accomplished in much the same way as on S*HFs by removing the exhaust fan access door (Panel B). SeeTables AC-4 and 5 for S*HG panel dimensions.
When using an IntelliPak™ Rooftop for horizontal supply and return, an additional pressure drop must be added to the supply external static to account for the 90 degree turn the air is making. This additional pressure drop depends on airflow and rooftop size, but a range of 0.10 inches to 0.30 inches can be expected.The openings on the rooftop all have a one inch lip around the
Figure AC-3 — Horizontal Discharge Panel Dimensions — 90 - 130Tons SXHG, SLHG, SSHG Units
perimeter to facilitate ductwork attachment. If exhaust fans are being used on an IntelliPak Rooftop unit with horizontal return, provisions should be made for access to the exhaust components, since the access door opening is now being used as a return. Perhaps the return ductwork attachment to the rooftop can include a section of removable duct. Use the dimensions provided and the supply and exhaust CFM to calculate the velocity (ft/min) through the openings.
Horizontal Discharge SXHG, SLHG, SSHG Rooftops (90 to 130 tons)
The SXHG, SLHG, SSHG rooftops can be field modified to supply and return air horizontally without the use of a horizontal supply/return curb.
To supply air horizontally, use Panel A only.The Panel on the opposite side cannot be used due to the location of the unit control Panel. SXHG rooftop air conditioners do not have a panel configuration like the 20 to 75 ton rooftops.To achieve maximum airflow, vertical support can be removed after the unit has been placed on the roof curb. It is secured by four screws. (See Note 1) For horizontal discharge on SLHG and SSHG units, only the Panel A next to the condenser fan section can be removed. The other Panel A next to the supply fan cannot be used due to the location of the heating coils.
To return air horizontally, the exhaust fan access door (Panel B) can be removed and used as a return opening.
Note:
1.SXHG units have two Panel A’s that can be removed. Once unit is installed, panel(s) and the 61/2” vertical support channel in between may be removed.

Application
Considerations
High Capacity Evaporator Coil
Rooftops are popular because of their “packaged” nature. Everything needed is contained in one box; mix-matching is neither necessary nor available.With this convenience comes some disadvantages; one is the rooftop’s cooling capacity may not exactly match the building load. It is conceivable that a 50 ton rooftop would need to be used on an application that is 41 tons, simply because the 40 ton rooftop does not meet capacity.
In order to avoid such occurrences, and to more closely match the rooftop’s capacity to the building load, a high capacity evaporator coil option is available on all IntelliPak™ Rooftops 20 to 105 tons.These high capacity coils have an increased number of evaporator coil rows as compared to standard and enhanced evaporator tube surfaces, resulting in a higher capacity. Capacity tables for both standard and high capacity coils are available in the cooling data section of this catalog. SeeTable PD-43 for the pressure drops associated with the high capacity coil option.This pressure drop should be added to the total static pressure used to size the supply fan motor.
Low Ambient Operation — Human
Interface Recommendations
Who wants to be on a roof at sub-zero temperatures?We can understand a service technician’s reluctance to do this; that’s why we recommend using a remote mounted Human Interface Panel. The service technician can troubleshoot and diagnose in the comfort of a mechanical room.
Corrosive Atmospheres
Trane’s IntelliPak Rooftops are designed and built to industrial standards and will perform to those standards for an extended period depending on the hours
of use, the quality of maintenance performed, and the regularity of that maintenance. One factor that can have an adverse effect on unit life is its operation in a corrosive environment.
When rooftops are operated in corrosive environments,Trane recommends that copper fins be utilized on the condenser and/or evaporator coil. Because copper is more resistant to corrosion than aluminum, coil life expectancy is greatly increased. Some industry applications expose equipment to corrosive agents that even copper cannot fully resist. For those special applications, a baked phenolic resin coating (i.e. Heresite) is highly desirable. Baked phenolic coatings or copper fins on the condenser and/or evaporator coils are available on Trane’s IntelliPak Rooftops.
Ventilation Override Sequences
One of the benefits of using an exhaust fan rather than a return fan, in addition to the benefits of lower energy usage and improved building pressurization control, is that the rooftop can be used as part of a ventilation override system. Several types of sequences can be easily done when exhaust fans are a part of the rooftop system.
What would initiate the ventilation override control sequence?Typically, a manual switch is used and located near the fire protection control panel.This enables the fire department access to the control for use during or after a fire. It is also possible to initiate the sequence from a field-installed automatic smoke detector. In either case, a contact closure begins the ventilation override control sequence. CAUTION!: The ventilation override system should not be used to signal the presence of smoke caused by a fire.
Trane can provide five (5) different ventilation override sequences on both CV andVAV IntelliPak Rooftops. For your
RT-PRC010-EN
convenience the sequences can be factory preset or fully field editable from the Human Interface Panel orTracer™. Any or all five sequences may be “locked” in by the user at the Human Interface Panel.
The user can customize up to five (5) different override sequences for purposes such as smoke control.The following parameters within the unit can be defined for each of the five sequences:
•Supply Fan — on/off
•Inlet GuideVanes — open/closed/ controlling
•Variable Frequency Drives — on (60 Hz)/off (0 Hz)/controlling
•Exhaust Fan — on/off
•Exhaust Dampers — open/closed
•Economizer dampers — open/closed
•Heat — off/controlling (output for)VAV Boxes — open/controlling
Compressors and condenser fans are shut down for anyVentilation Override sequence. Factory preset sequences include unit Off, Exhaust, Purge, Purge with duct pressure control, and Pressurization. Any of the user-defined Ventilation Override sequences can be initiated by closing a field supplied switch or contacts connected to an input on theVentilation Override Module. If more than one ventilation override sequence is being requested, the sequence with the highest priority is initiated. Refer to the Sequence of Operation provided in the Control section of this catalog for more details on each override sequence.
Natural Gas Heating Considerations
The IntelliPak standard, or limited modulation, gas heat exchangers are not recommended for applications with mixed air conditions entering the heat exchanger below 50°F. Mixed air temperatures below 50°F can cause condensation to form on the heat exchanger, leading to premature failure.
13
Application
Considerations
For increased reliability, the recommendation in these applications is full modulation gas heat. For airflow limitations and temperature rise across the heat exchanger information, see Table PD-24, 25 and RT-EB-104.
Acoustical Considerations
The ideal time to make provisions to reduce sound transmission to the space is during the project design phase. Proper placement of rooftop equipment is critical to reducing transmitted sound levels to the building.The most economical means of avoiding an acoustical problem is to place any rooftop equipment away from acoustically critical area. If possible, rooftop equipment should not be located directly above areas such as: offices, conference rooms, executive office areas and classrooms. Ideal locations are above corridors, utility rooms, toilet facilities, or other areas where higher sound levels are acceptable.
Several basic guidelines for unit placement should be followed to minimize sound transmission through the building structure:
1
Never cantilever the condensing section of the unit. A structural cross member must support this end of the unit.
2
Locate the unit’s center of gravity close to or over a column or main support beam to minimize roof deflection and vibratory noise.
3
If the roof structure is very light, roof joists should be replaced by a structural shape in the critical areas described above.
4
If several units are to be placed on one span, they should be staggered to reduce deflection over that span.
It is impossible to totally quantify the effect of building structure on sound transmission, since this depends on the response of the roof and building members to the sound and vibration of the unit components. However, the guidelines listed above are experience proven guidelines which will help reduce sound transmission.
There are several other sources of unit sound, i.e., supply fan, compressors, exhaust fans, condenser fans and aerodynamic noise generated at the duct fittings. Refer to the ASHRAE Applications Handbook, Chapter 42, 1991 edition for guidelines for minimizing the generation of aerodynamic noise associated with duct fittings.
Trane’s Engineering Bulletin RT-EB-80 describes various duct installation considerations specifically addressing indoor sound level concerns.This bulletin includes sound power data on Trane’s IntelliPak Rooftops 20 to 130 tons. Ask your localTrane representative for this informative engineering bulletin.
TheVariTrane™ Computerized Duct Design Program can be used to analyze the truck duct, run-out duct,VAV control unit and terminal unit noise attenuation. This program quantifies the airborne sound generation that can be expected in each terminal so that the designer can identify potential sound problems and make design alterations before equipment installation.
TheTrane Acoustics Program (TAP) allows modeling of rooftop installation parameters.The output of this program shows the resulting indoor NC level for the modeled installation.This program is available fromTrane’s Customer Direct Service Network™ (C.D.S.), ask your localTrane representative for additional information on this program.
Clearance Requirements
The recommended clearances identified with unit dimensions should be
maintained to assure adequate serviceability, maximum capacity and peak operating efficiency. A reduction in unit clearance could result in condenser coil starvation or warm condenser air recirculation. If the clearances shown are not possible on a particular job, consider the following:
•Do the clearances available allow for major service work such as changing compressors or coils?
•Do the clearances available allow for proper outside air intake, exhaust air removal and condenser airflow?
•If screening around the unit is being used, is there a possibility of air recirculation from the exhaust to the outside air intake or from condenser exhaust to condenser intake?
Actual clearances which appear inadequate should be reviewed with a localTrane sales engineer.
When two or more units are to be placed side by side, the distance between the units should be increased to 150 percent of the recommended single unit clearance.The units should also be staggered as shown in Figure AC-4 for two reasons:
1
To reduce span deflection if more than one unit is placed on a single span. Reducing deflection discourages sound transmission.
2
To assure proper diffusion of exhaust air before contact with the outside air intake of adjacent unit.

Application
Considerations
Duct Design
It is important to note that the rated capacities of the rooftop can be met only if the rooftop is properly installed in the field. A well-designed duct system is essential in meeting these capacities.
The satisfactory distribution of air throughout the system requires that there be an unrestricted and uniform airflow from the rooftop discharge duct. This discharge section should be straight for at least several duct diameters to allow the conversion of fan energy from velocity pressure to static pressure.
However, when job conditions dictate elbows be installed near the rooftop outlet, the loss of capacity and static pressure may be reduced through the use of guide vanes and proper direction of the bend in the elbow.The high velocity side of the rooftop outlet should be directed at the outside radius of the elbow rather than the inside as illustrated in Figure AC-5.

Selection
Procedure
This section outlines a step-by-step procedure that may be used to select a Trane single-zone air conditioner.The sample selection is based on the following conditions:
•Summer outdoor design conditions — 95 DB/76WB ambient temperature
•Summer room design conditions —78 DB/65WB
•Total cooling load — 430 MBh (35.8 tons)
•Sensible cooling load — 345 MBh (28.8 tons)
•Outdoor air ventilation load — 66.9 MBh
•Return air temperature — 80 DB/65WB
Winter Design:
•Winter outdoor design conditions —0 F
•Return air temperature — 70 F
•Total heating load — 475 MBh
•Winter outdoor air ventilation load — 133 MBh
Air Delivery Data:
•Supply fan cfm — 17,500 cfm
•External static pressure — 1.2 in wg
•Minimum outdoor air ventilation — 1,750 cfm
•Exhaust fan cfm — 12,000 cfm
•Return air duct negative static pressure
— 0.65 in wg
Electrical Characteristics:
•Voltage/cycle/phase — 460/60/3 Unit Accessories:
•Gas fired heat exchanger — high heat module
•Throwaway filters
•Economizer
•Modulating 100 percent exhaust/ return fan
COOLING CAPACITY SELECTION
Step 1 — Nominal Unit Size Selection
A summation of the peak cooling load and the outside air ventilation load shows: 430 MBh + 66.9 MBh = 496.9 MBh required unit capacity. From
16
Table PD-9, a 50 ton unit capacity with standard capacity evaporator coil at 80 DB/65WB, 95 F outdoor air
temperature and 17,500 total supply cfm is 551 MBh total and 422 MBh sensible. Thus, a nominal 50 ton unit with standard capacity evaporator coil
is selected.
Step 2 — Evaporator Coil Entering
Conditions
Mixed air dry bulb temperature determination:
Using the minimum percent of OA (1,750 cfm ÷ 17,500 cfm = 10 percent), determine the mixture dry bulb to the evaporator.
RADB + % OA (OADB - RADB) = 80 + (0.10) (95 - 80) = 80 + 1.5 = 81.5 F
Approximate wet bulb mixture temperature:
RAWB + % OA (OAWB - RAWB) = 65 + (0.10) (76 - 65) = 65 + 1.1 = 66.1 F
Step 3 — Determine Supply Fan Motor
Heat Gain
Having selected a nominal 50 ton unit, the supply fan bhp can be calculated.The supply fan motor heat gain must be considered in final determination of unit capacity.

Using total of 17,500 cfm and total static pressure of 2.76 inches, enterTable PD-36.Table PD-36 shows 15.3 bhp with 924 rpm.
From Chart SP-1 supply fan motor heat gain = 46.0 MBh.
Step 4 — DetermineTotal Required
Cooling Capacity
Required capacity =Total peak load + OA load + supply air fan motor heat.
Required capacity = 430 + 66.9 + 46.0 = 543 MBh (45.2 tons)
Step 5 — Determine Unit Capacity
FromTable PD-9, unit capacity at 81.5 DB/ 66.1WB entering the evaporator, 17,500 supply air cfm, 95 F outdoor ambient, is 561 MBh (45.8 tons) with 426 MBh sensible.
Step 6 — Determine Leaving Air
Temperature
Unit sensible heat capacity corrected for supply air fan motor heat = 426 MBh - 46 MBh = 380 MBh.

Procedure
HEATING CAPACITY SELECTION
Step 1 — Determine AirTemperature
Entering Heating Module
Mixed air temperature = RADB + % OA (OADB - RADB) = 70 + (0.10) (0 - 70) = 63 F
Supply air fan motor heat temperature rise = 46,000 Btu ÷ (1.085 x 17,500 cfm) = 2.42 F
Air temperature entering heating module = 63.0 + 2.42 = 65.4 F
Step 2 — DetermineTotalWinter Heating
Load
Total winter heating load = peak heating load + ventilation load - supply fan motor heat = 475 + 133 - 46.0 = 562 MBh
Electric Heating System
Unit operating on 460/60/3 power supply.
FromTable PD-30, kw may be selected for a nominal 50 ton unit operating
460-volt power.The 170 kw heat module
(580.1 MBh) will satisfy the winter heating load of 563 MBh.
Table PD-28 shows an air temperature rise of 30.6 F for 17,500 cfm through the 170 kw heat module.
Unit supply temperature at design heating conditions = mixed air temperature + air temperature rise = 65.4 F + 30.6 F = 96.0 F.
Gas Heating System (Natural Gas)
FromTable PD-24 select the high heat module (697 MBh output) to satisfy winter heating load of 563 MBh at unit cfm.
Table PD-26 also shows an air temperature rise of 36.0 F for 17,500 cfm through the heating module.
Unit supply temperature at design heating conditions = mixed air temperature + air temperature rise = 65.4 F + 36.0 F = 101.4 F.
HotWater Heating
Assume a hot water supply temperature of 190 F. Subtract the mixed air temperature from the hot water temperature to determine the ITD (initial temperature difference).

MOTOR BRAKE HORSE POWER
ITD = 190 F - 65.4 F = 125 F. Divide the winter heating load by ITD = 563 MBh ÷ 125 F = 4.50 Q/ITD.
FromTable PD-31, select the low heat module. By interpolation, a Q/ITD of 4.50 can be obtained at a gpm at 25.7.
Water pressure drop at 25.7 gpm is 0.57 ft. of water. Heat module temperature rise is determined by:

Unit supply air temperature = mixed air temperature + air temperature rise = 65.4 + 29.7 = 95 F.
Steam Heating System
Assume a 15 psig steam supply.
FromTable PD-27, the saturated temperature steam is 250 F. Subtract mixed air temperature from the steam
temperature to determine ITD. ITD = 250 F - 65.4 F = 185 F.
Divide winter heating load by ITD = 563 MBh ÷ 185 F = 3.04 Q/ITD.
FromTable PD-26, select the high heat module.The high heat module at 17,500 cfm has a Q/ITD = 5.11.
Heat module capacity, Q = ITD x Q/ITD = 185 F x 5.11 Q/ITD = 945 MBh

1.085 x Supply cfm
945 Btu ÷ (1.085 x 17,500 cfm) = 49.8 F.

Selection
Procedure
AIR DELIVERY PROCEDURE
Supply fan performance tables include internal resistance of rooftop. For total static pressure determination, system external static must be added to appropriate component static pressure drop (evaporator coil, filters, optional economizer, optional exhaust fan, optional heating system, optional cooling only extended casing, optional roof curb).
Supply Fan Motor Sizing
The supply fan motor selected in the cooling capacity determination was 15.3 bhp and 924 rpm.Thus, a 20 hp supply fan motor is selected. EnterTable PD-45 to select the proper drive. For a 50 ton rooftop with 20 hp motor, a drive number 9 — 900 rpm is selected.
Exhaust Fan Motor Sizing
The exhaust fan is selected based on total return system negative static pressure and exhaust fan cfm. Return system negative static include return duct static and roof curb static pressure drop.
Return duct static pressure = 0.65 inches
Trane roof curb (Table PD-43) = 0.12 inches
Total return system negative static pressure = 0.77 inches
Exhaust fan cfm = 12,000 cfm
FromTable PD-47, the required bhp is 3.45 hp at 574 rpm.Thus, the exhaust fan motor selected is 5 hp.
To select a drive, enterTable PD-49 for a 5 hp motor for a 50 ton unit. Drive selection number 6 — 600 rpm.
Where altitudes are significantly above sea level, useTables PAF-2 and PAF-3 and Figure PAF-1 for applicable correction factors.
UNIT ELECTRICAL REQUIREMENTS
Selection procedures for electrical requirements for wire sizing amps, maximum fuse sizing, and dual element fuses are given in the electrical service section of this catalog.
Altitude Corrections
The rooftop performance tables and curves of this catalog are based on standard air (.075 lbs/ft). If the rooftop airflow requirements are at other than standard conditions (sea level), an air density correction is needed to project accurate unit performance.
Figure PAF-1 shows the air density ratio at various temperatures and elevations. Trane rooftops are designed to operate between 40 and 90 degrees Fahrenheit leaving air temperature.
The procedure to use when selecting a supply or exhaust fan on a rooftop for elevations and temperatures other than standard is as follows:
1
First, determine the air density ratio using Figure PAF-1.
2
Divide the static pressure at the nonstandard condition by the air density ratio to obtain the corrected static pressure.
3
Use the actual cfm and the corrected static pressure to determine the fan rpm and bhp from the rooftop performance tables or curves.
4
The fan rpm is correct as selected.
5
Bhp must be multiplied by the air density ratio to obtain the actual operating bhp.
18 |
RT-PRC010-EN |
Selection
Procedure
In order to better illustrate this procedure, the following example is used:
Consider a 60 ton rooftop unit that is to deliver 18,000 actual cfm at 3-inches total static pressure (tsp), 55 F leaving air temperature, at an elevation of 5,000 ft.
1
From Figure PAF-1, the air density ratio is 0.86.
2
Tsp = 3.0-inches / 0.86 = 3.49 inches tsp.
3
From the performance tables: a 60 ton rooftop (without inlet vanes) will deliver 18,000 cfm at 3.49-inches tsp at 906 rpm and 21.25 bhp.
4
The rpm is correct as selected - 906 rpm.
5
Bhp = 21.25 x 0.86 = 18.3 bhp actual.
Compressor MBh, SHR, and kw should be calculated at standard and then converted to actual using the correction factors inTable PAF-2. Apply these factors to the capacities selected at standard cfm so as to correct for the reduced mass flow rate across the condenser.
Heat selections other than gas heat will not be affected by altitude. Nominal gas capacity (output) should be multiplied by the factors given inTable PAF-3 before calculating the heating supply air temperature.
HEATING CAPACITY SELECTION
Step 1 — Determine AirTemperature
Entering Heating Module
Mixed air temperature = RADB + % OA (OADB - RADB) = 70 + (0.10) (0 - 70) = 63 F
Supply air fan motor heat temperature rise = 46,000 Btu ÷ (1.085 x 17,500 cfm) = 2.42 F
Air temperature entering heating module = 63.0 + 2.42 = 65.4 F
