Application Considerations
Condensate Piping
The horizontal unit ventilator drain pan connection is located on the same side as the cooling coil
connections (hydronic and DX coils). The stubout size is 3 /4” outside diameter.
All field supplied condensate lines to the unit should contain 1/4” in 12” slope away from the unit
ventilator to aid in condensate removal. This is typical for most local codes. A trap is also
recommended somewhere in the condensate system.
Note: Drain pan connections are field convertible.
Ducted Applications
A well designed duct system is beneficial to obtaining satisfactory fan performance. Determining
resistance losses for the duct work system is also necessary for acceptable fan performance.
Assistance in the design of duct work can be found in the ASHRAE Handbook. The unit ventilator
is designed to operate against ESP thru 0.45”. The ESP is determined by adding the discharge air
static pressure to the greater of either the outdoor air static pressure or the return air static
pressure.
The Applied Unit Ventilator
A Choice in System Design
The beauty of the classroom unit ventilator stems beyond its ability to heat and cool. The Trane unit
ventilator design provides an opportunity to create a comfortable atmosphere for living, learning
and playing, while providing energy efficiency savings with market-leading technology. Some of
the featured benefits of a unit ventilator are:
• Individual room control.
• Fresh air ventilation and filtration.
• Individual dehumidification sequences per zone.
• Energy savings solutions through economizing functions.
• A choice in heating/cooling applied systems.
• And, because the equipment is mounted directly in the
space, installation costs are minimal
compared to other HVAC systems.
