Features and Benefits Features Summary IntelliPak™ rooftop features make installation and servicing easy and reliable operation a reality.
Features and Benefits 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).
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.
Features and Benefits 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.
Application Considerations EXHAUST AIR OPTIONS Application Recommendations d 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.
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.
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.
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.
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.
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.
Application Considerations Duct Design Figure AC-4 — Unit Placement 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. 1 The satisfactory distribution of air throughout the system requires that there be an unrestricted and uniform airflow from the rooftop discharge duct.
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/76 WB ambient temperature • Summer room design conditions —78 DB/65 WB • Total cooling load — 430 MBh (35.8 tons) • Sensible cooling load — 345 MBh (28.8 tons) • Outdoor air ventilation load — 66.
Selection Procedure HEATING CAPACITY SELECTION Chart SP-1 — Fan Motor Heat Step 1 — Determine Air Temperature Entering Heating Module STANDARD MOTOR HIGH EFFICIENCY MOTOR Mixed air temperature = RADB + % OA (OADB - RADB) = 70 + (0.10) (0 - 70) = 63 F 120 Supply air fan motor heat temperature rise = 46,000 Btu ÷ (1.085 x 17,500 cfm) = 2.42 F 100 Step 2 — Determine Total Winter Heating Load Total winter heating load = peak heating load + ventilation load - supply fan motor heat = 475 + 133 - 46.
Selection Procedure AIR DELIVERY PROCEDURE UNIT ELECTRICAL REQUIREMENTS 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).
Selection Procedure In order to better illustrate this procedure, the following example is used: HEATING CAPACITY SELECTION 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. Mixed air temperature = RADB + % OA (OADB - RADB) = 70 + (0.10) (0 - 70) = 63 F 1 From Figure PAF-1, the air density ratio is 0.86.

VAV Units Only Sequence Of Operation NOTE: When noted in this sequence “Human Interface Panel,” the reference is to both the unit mounted and remote mounted Human Interface Panel. All setpoint adjustments can be accomplished at the unit or Remote Human Interface Panel. Controls (VAV Units) Inlet guide vane assemblies installed on the supply fan inlets regulate fan capacity and limit horsepower at lower system air requirements.
Controls (VAV Units) Heating: Hot Water or Steam Supply Air Setpoint Reset On units with hot water or steam heating, the supply air temperature can be controlled to a heating set point during the Occupied mode.The supply air temperature heating set point and deadband are user-defined at the Human Interface Panel. VAV Occupied heating on hot water and steam heat units is enabled by closing a field-supplied switch or contacts connected to an changeover input on the RTM.
Controls (CV Units) CV Units Only A Sequence Of Operation Heating 1 Gas Heating - Two-Stage Occupied Zone Temperature Control Upon a call for heating, the UCM closes the first stage heating contacts beginning the firing sequence. First, the heat exchanger combustion blower begins operation. Upon positive proving of combustion airflow, a pre-purge cycle is executed.Then the ignition sequence takes place.
Controls (CV Units) Gas Heating: Modulating Gas drive it full open. If the supply fan is on, or if the outside air damper is open when this freezing condition is sensed, the supply fan is turned off and the outside air damper is closed. Upon a call for heating, the UCM closes the heating contacts, beginning the firing sequence. First, the heat exchanger combustion blower begins operation. Upon positive proving of combustion airflow, a pre-purge cycle is executed. Then the ignition sequence takes place.
Control Sequences of Operation Common to Both VAV and CV Units 1 Space Pressure Control — Statitrac™ A pressure transducer is used to measure and report direct space (building) static pressure.The userdefined control parameters used in this control scheme are space static pressure setpoint and deadband. As the economizer opens, the building pressure rises and enables the exhaust fan and dampers or exhaust VFD.The exhaust dampers or VFD then modulate to maintain space pressure within the deadband.
PURGE sequence “D” Possibly this sequence could be used for purging the air out of a building before coming out of Unoccupied mode of operation on VAV units or when the purging of smoke or stale air is required after a fire. - Supply fan - On. - Supply fan VFD - On (60 Hz) (if equipped) - Inlet guide vanes/VAV boxes - Open (if equipped). - Exhaust fan - On, exhaust dampers Open (if equipped). - Exhaust fan VFD - On (60 Hz) (if equipped) - Outside air dampers - Open.
Human Interface Panel Main Menu • STATUS — used to monitor all temperatures, pressures, humidities, setpoints, input and output status. The • CUSTOM key allows the user to customize a status report—consisting of up to (4) screens of the data available in the main Status menu. • SET POINTS — used to edit all factory preset Default setpoints • DIAGNOSTICS — used to review active and historical lists of diagnostic conditions. A total of 49 different diagnostics can be read at the Human Interface Panel.
Controls (VAV/CV Units) Occupied/Unoccupied input on the RTM temperature and humidity of both return air and outside air to determine which source has lower enthalpy.This system allows true comparison of outdoor air and return air enthalpy by measurement of outdoor air and return air temperatures and humidities. This input accepts a field supplied switch or contacts closure such as a time clock. Trane Tracer™ System TheTraneTracer System can control the Occupied/Unoccupied status of the rooftop.
