5 RT -PRC0 10-EN Fea tur es Summary IntelliPak ® rooftop features make installation and servicing easy and reliable operation a reality . Installation Ease • F actory-installed/commissioned control.
RT -PRC01 0-EN 6 F eatures and Benef its Integrated Roof top S ystems: P r of itable, Simple Int egrated Comf or t ™ S ystem (ICS) T rane integrated rooftop systems make design and installation of roof top comfort systems profitable and easy .
7 RT -PRC0 10-EN Features and Benef its The modular control design of the UCM allows for greater application flexibility . Customer s can order exactly the options required for the job, instead of one large control pac kage. Unit features are distributed among multiple field replaceable printed circuit boards.

The single orbiting scroll eliminates the need for pistons, connecting rods, wrist pins and valves.
9 RT -PRC0 10-EN Application Considerations EXHA UST 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.
RT -PRC01 0-EN 10 Application Considerations Figure A C-1 — Plan View of Modulating 1 00 Per cent Exhaust Syst em 2 1 00 Per cent Exhaust S ystem Competiti ve rooftops use a return air fan system for controlling the amount of exhaust air during economizer operation.

RT -PRC01 0-EN 12 Figure AC-3 is a simplified sketch showing whic h 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.
13 RT -PRC0 1 0-EN High Capacity Ev aporat or Coil Roo ftops are popular because of their “ pac kaged ” nature. Everything needed is contained in one box; mix -matc hing is neither necessary nor available. With this convenience comes some disadvantages; one is the rooftop ’ s cooling capacity may not exactly matc h the building load.

15 RT -PRC0 1 0-EN 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.
RT -PRC01 0-EN 16 S election P r ocedure This section outlines a step-by -step procedure that may be used to select a T rane single-zone air conditioner .
17 RT -PRC0 1 0-EN S election P rocedure ITD = 1 90 F - 65.4 F = 125 F . Divide the winter heating load by ITD = 563 MBh ÷ 125 F = 4.50 Q/ITD. From T able PD-31, select the low heat module. By interpolation, a Q/ITD of 4.50 can be obtained at a gpm at 25.
RT -PRC01 0-EN 18 AIR DELIVER Y PROCEDURE Supply fan performance tables include internal resistance of rooftop. F or total static pressure determination, system external static must be added to approp.
19 RT -PRC0 1 0-EN S election P r ocedure In order to better illustrate this procedure, the following example is used: Consider a 60 ton rooftop unit that is to deli ver 18,0 0 0 actual cfm at 3-inc hes total static pressure (tsp), 55 F leaving air temperature, at an elevation of 5,0 0 0 ft .
