 VAV Damper  A to Z Products
 Introduction
 
Application:

COSMOS make Variable Air Volume Damper (VAV–D) is pressure independent air volume control terminal with inbuilt pressure sensor flow grid.

COSMOS VAV-D terminal, features a primary inlet with an integral damper and design to meet the needs of today’s VAV systems.

Unit is design particularly for system with larger air volume and duct sizes and for accurate measurement and control of air volume.
 
The unit controls the air volume to the zone, depending on the cooling load required, thus saving energy consumption in cooling application.


 
  Model: VAV-D
 
 
  Operating principle :
 
The VAV-D is the most common air terminal unit offered by “COSMOS”. It operates on the principle that as cooling load is satisfied, the primary damper modulates closed to restrict airflow to the space so that a constant space temperature is maintained.

As the space cooling load is further satisfied, the VAV-D closes to pre-set minimum flow which is usually determined by the minimum level of ventilation. In addition, the VAV-D can also used at full shut-off for those applications where minimum ventilation requirements are not necessary.
