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.
PAGE 10
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.
PAGE 11
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.
PAGE 12
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.
PAGE 13
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.
PAGE 14
Application Considerations exchanger, leading to premature failure. 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.
PAGE 15
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.
PAGE 16
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.
PAGE 18
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).
PAGE 19
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.
