Displacement Ventilation (DV) is a cost-effective means of providing
an optimal indoor environment by delivering cool supply air directly to the occupants
in a space.
What are
the benefits?
Displacement ventilation systems offer an effective,
energy-efficient way of delivering freshly conditioned air and removing
airborne pollutants to improve comfort and air quality. Indoor air quality is
improved since the rising thermal plumes carry away contaminants toward the
ceiling exhaust. Displacement ventilation can improve acoustics because of the
low background noise caused by low supply air velocities and the remotely
located cooling and delivery equipment.
How does
it save energy?
There are several reasons behind the cooling energy savings
with DV. First and foremost, the higher supply air temperature of 65°F
greatly increases the potential for free cooling. Secondly, the higher supply
air temperature also increases the efficiency of mechanical cooling equipment.
How to
apply DV units?
Supply air must reach the occupied space at velocities
comfortable for the occupant(s). The zone closest to the displacement
ventilation unit with velocities exceeding 50 fpm is called “Near Zone” or “Adjacent
Zone.” To achieve maximum room occupancy for each job application, the near
zone has to be adjusted to a minimum. To ensure good comfort in the room, a
flexible pattern controller pattern makes it possible to alter the adjacent
airflow pattern.
How does
the new Titus pattern controller work?
Titus engineering utilized their recent experience with
displacement products and projects in which this technology was
applied. The new pattern controller is an evolution from a single pattern
controller to a cluster of metal controllers. Not only will this be a product
quality improvement, it also simplifies the controller adjustment at the job
site. Performance is not affected by the product change; so you will be able to
continue using the performance data listed in the catalog. Titus was able to
maintain the same application data by upgrading the deflection of the perforated
area on the front covers.
We improved
this product family to enhance quality and provide the
most flexible product on the US market today.
