The Temperature
Ambient Optimizer (TAO) by Titus is a hybrid unit that takes advantage of
displacement, chilled beams, and radiation principles.
This revolutionary
product is specifically designed for high-ventilation loads – greater than 200
BTUH per foot -- normally required in educational facilities, theaters and long
hallways that have perimeter walls or windows.
What it Accomplishes:
The TAO can help find
the path to a balanced and healthy system by providing the right proportion of
heating or cooling to the perimeter wall to take care of the majority of the
room load. Within desirable acoustic levels, it maintains the necessary displacement
ventilation, humidity control, and temperature level of the room.
Supply air is
discharged into the space -- at low air velocity -- as close to the floor as
possible. This provides a very low and slow-moving pool of fresh air spreading
over the entire floor.
Convection from
people and other heat sources causes the fresh air to rise, which helps create
very comfortable conditions in the occupied zone.
Comfort – temperature
and air movement – is met by optimizing the air path wherein the two major
loads are located. At the same time, the unit meets minimum ventilation
requirements.
By redirecting a
portion of the treated supply air toward the cold, outside wall/window, the
heat load is neutralized and a thermal curtain is created. This reduces convection
and radiation associated with the cold wall or window.
Description of
Operation:
TAO units are
provided with a constant volume flow of conditioned outside air that ranges
between a 55°F and 66°F supply-air temperature from the air
handler.
The most significant
portion of the air is injected into the induction plenum and through the
primary set of nozzles into the lower part of the unit and displaced into the
room.
As the conditioned
air leaves the nozzle, it will also induce the room air through the water coil
to heat or cool the return air. Here, it is reconditioned, mixed with primary
air, and delivered into the room at a discharge temperature of 64°F to 72°F.
The
other portion of conditioned outside air is discharged through a secondary set
of nozzles that are directed toward the outside wall/window. This neutralizes
the perimeter load.
The secondary set of
nozzles induce room air through the secondary coil to increase the temperature
of the supply air during heating mode.
The hot air rises
along the perimeter walls and windows to neutralize the thermal load by
creating a warm air curtain.
Benefits:
Since there are no
blowers or motors operating within the TAO unit, the sound levels are further
reduced and the overall energy consumption of the system can be improved.
According to the
Building Owners and Managers Association, 60 percent of a building’s operating
costs come from energy-related expenditures. To provide efficiency and help
curb costs, the TAO takes advantage of all LEED certification requirements to
obtain energy credits.
In addition, the
stricter ASHRAE Standards of Thermal Comfort (Standard 55), Energy Savings and
Perimeter Heating (Standard 90.1) can be easily achieved with this product in
use.
Available in two unit
sizes, the TAO is designed to fit under the window sill adjacently to the
perimeter wall. Titus offers customizable cabinets in a variety of
aesthetically pleasing woodgrain and natural stone finishes.
