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:.

All setup parameters are preset from the factory, requiring less start-up time during installation. This common interface feature requires less time for building maintenance personnel to learn to interact with the unit. 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. The efficiency is achieved with a 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 percent modulating exhaust system are at part load, saving more energy. 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. 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 unloading characteristics result in superior part load performance. Bypass control will simply provide full nominal airflow in the event of drive failure. 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.

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. 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.

With over twenty years of development and testing,Trane 3-D Scroll compressors have undergone more. One of two matched scroll plates — the distinguishing feature of the scroll compressor. This work combined with over 25 patents makesTrane the worldwide leader in air conditioning scroll compressor technology. Chart illustrates low torque variation of 3-D Scroll compressor vs reciprocating compressor.

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.

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.

Statitrac compensates for pressure variations within the building from remote exhaust fans and makeup air units. The exhaust fan discharges in a single direction resulting in more efficient fan operation compared to return fan systems.

Because discharge dampers modulate the airflow, the exhaust fan may be running unloaded whenever the economizer dampers are less than 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 percent modulating exhaust system with Statitrac does a better job controlling building pressure than return fans simply because 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 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. 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.

This fan system has performance capabilities equal to the supply fan. The FC exhaust fans are started by the. 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. 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. 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.

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. The typical rooftop installation has both the supply and return air paths routed through the roof curb and building roof.

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.

With this method the standard discharge and return openings are blocked in the field. These openings are used for the discharge and return.

No special curb is needed. 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.

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.

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.

Panel A cannot be used due to the location of the heating coils. 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. Supply and Return Base openings must be covered when converting to a horizontal configuration. Add an extra 0. The openings all have a 1. If exhaust fans are being used, provisions should be made for access to the exhaust components, since the access door is now being used as a return. On 90 to 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. This additional pressure drop depends on airflow and rooftop size, but a range of 0. The openings on the rooftop all have a one inch lip around the.

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. 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. 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. Everything needed is contained in one box; mix-matching is neither necessary nor available.

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.

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 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. Who wants to be on a roof at sub-zero temperatures?

The service technician can troubleshoot and diagnose in the comfort of a mechanical room. One factor that can have an adverse effect on unit life is its operation in a corrosive environment. 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. Heresite is highly desirable. 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.

For your. 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:.

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. For increased reliability, the recommendation in these applications is full modulation gas heat.

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:.
