The Displacement Ventilation Solution

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.
