UFAD/DV
This is the ideal location for a ceiling mounted displacement diffuser
What are Transient areas?
The component of a terminal unit which opens and closes to regulate airflow.
What is a damper?
This material is typically the most cost effective option for Price Industries GRD products.
This type of chilled beam requires airflow through the unit.
What is an ACTIVE chilled beam (or ACB)?
Another name to describe the VFX.
What is a high accuracy terminal unit?
This is the most cost-effective underfloor solution for perimeter applications
What is LNT?
The type of sound that breaks out through the casing of a terminal unit.
What is radiated sound?
The required length of straight hard duct upstream of the diffuser, per ASHRAE 70-2006.
What is 3 equivalent duct diameters?
This chilled beam unit can provide sensible cooling without supply air.
What is a PASSIVE chilled beam (or PCBL)?
When a reheat or cooling coil will operate from 0-100% at the same time airflow is added to the room.
What is synchronous temperature control?
This is the parameter by which we size displacement diffusers.
What is 40fpm face velocity?
The reheat accessory commonly installed on the discharge of a unit which allows for an instantaneous response to heat.
What is an electric coil?
Most diffusers are tested while installed in a ceiling. However, when they are installed without a ceiling, the throw length should be adjusted by this amount.
What is 0.70 (or reduced by 30%)?
This is typically induced through an active chilled beam's water coil?
What is Room Air?
The most common type of coating used on VV/VFX in corrosive fume hood applications.
What is Phenolic Class 1 coating?
This sensor is critical to the success of every underfloor project.
What is a Plenum Pressure Sensor?
The pressure provided by the air handler to the inlet of a terminal unit.
What is inlet static pressure?
The typical source of dirt embedded in the ceiling, sometimes called "Smudging".
What is poor house keeping?
This is recommended for the entering chilled water temperature for non-condensing beam applications.
What is 2-3 degrees above room dew point?
This requires a room pressure sensor and some sort of display (i.e. local monitor, front end system, etc.).
What is room pressure monitoring?
The Ventilation effectiveness for ceiling heights above 18ft.
What is 1.5?
The phenomenon in which a poor inlet condition has a negative impact on airflow measurement, control, sound generation, and pressure drop.
What is "system effect"?
This is the rule-of-thumb depth of a ceiling obstruction that will obstruct the path of an air jet from the diffuser.
What is any depth that is equal to or greater than a 10 degree angle from the diffuser?
This contributes to energy savings by using a chilled beam system.
What is: Using the water side to call/heat space instead of just air? Induction through the coil? Reduction in air, air handler size, fan energy?
What is the door contact switch (DCS)?
