Outdoor Air Systems

Trane dedicated outdoor air systems:

Improving indoor air quality and lowering HVAC costs

High indoor
occupancy levels,
busy kitchens and
shower facilities can
significantly increase
indoor humidity
levels—which can
make occupants
uncomfortable.

Achieving acceptable indoor air quality can be

difficult—especially when using some traditional

packaged rooftop HVAC systems. Many of

these systems don’t have the latent capacity

to effectively manage high humidity levels,

which can result in uncomfortable conditions

for building occupants—even when packaged

rooftop HVAC systems are operating at full

capacity and consuming high amounts of energy.

Adding a Trane® dedicated outdoor air system

can not only improve indoor air quality, but also

reduce HVAC operating costs. By cooling and

filtering outdoor air before directing an optimal

amount of it into a building, a Trane dedicated

outdoor air system can not only help maintain

compliance with ASHRAE 62.1 ventilation

standards, but also can decrease indoor humidity

and reduce the load on HVAC systems. The

result is improved occupant comfort and lower

utility bills.

Breathe easier with lower energy bills

Trane dedicated outdoor air systems can be

an energy-saving partner for your heating

and cooling system, allowing it to work more

efficiently. When incorporated as part of an

HVAC system’s total design, a Trane dedicated

outdoor air system can mean smaller, less-

expensive, more energy-efficient local or zone

terminal devices can be specified, saving money

on first costs. A Trane dedicated outdoor air

system can pay for itself in a short amount of

time, saving you money on first costs and utility

bills. And with a life span of up to 20 years or

more, you can expect a Trane dedicated outdoor

air system to save money on utility bills for a long

time to come.

Code compliance: Following regulations

with proper ventilation

Trane dedicated outdoor air systems are an ideal

way to ensure full compliance with ASHRAE

62.1 ventilation standards. Integrated with Trane

controls, Trane dedicated outdoor air systems

can precisely deliver the right amount of outdoor

air into your building, not only ensuring full

compliance with applicable building codes that

reference ASHRAE 62.1, but also meeting or

exceeding the air pressure specifications of your

building’s design. The benefits include:

• Avoiding monetary building code penalties

and/or mandated corrective action

• Mitigating the infiltration of high-humidity

outside air

• Having the capacity for increased ventilation

rates to meet future requirements

Indoor air quality: Improving the life of

your building, improving the life of its

occupants

Various factors can influence a building’s indoor

air quality (IAQ), including humidity, the presence

of contaminants and more. Good IAQ contributes

to occupant comfort—and comfortable building

occupants are less likely to have work absences,

can be more productive, and are more likely to

remain building tenants longer. Additionally, a

building with superior IAQ can deliver higher

rental income.

The benchmark method for improving a building’s

IAQ is the introduction of fresh outdoor air—but

unless that outdoor air is properly conditioned,

it can bring with it undesirable temperatures,

humidity and contaminants. Trane dedicated

outdoor air systems can be the single best

way to quickly and economically improve your

building’s IAQ by properly conditioning outdoor

air, controlling its humidity and filtering out

contaminants.

Humidity control—Trane dedicated outdoor

air systems contain a specially designed six-row

evaporator coil that can quickly dehumidify

incoming outdoor air—and is optimally

engineered to maximize both moisture removal

and energy savings.

Contaminant removal—Multiple types of

air filters are compatible with Trane dedicated

outdoor air systems to keep pollen, dust and

other outdoor air contaminants from entering

your building.

Microorganism control—Trane dedicated

outdoor air systems are available with a UV-C

band irradiation light to inhibit the growth of

microorganisms that otherwise could thrive on

the wet surface of an evaporator coil, keeping

them out of the air that passes through the

evaporator coil and into your building’s interior.

Comfortable building
occupants are less
likely to have work
absences, can be more
productive, and are
more likely to remain
building tenants
longer.
