Variable air volume

We also manufacture variable air volume of high quality in UAE. VAV systems maintain a constant air temperature and instead change airflow according to the load. Single, multi-zone or dual duct configurations can apply to VAV systems. Just as CAV is the preferred option for single-zone systems, for multi-zone systems VAV is also advisable.

Dual VAV systems have separate hot and cold air ducts, and the ventilation in each region is combined in complete compartments. The hot and cold air ratio varies according to the desired temperature in each region. In terms of installation, service and maintenance, this HVAC setup is the most costly.

There are VAV boxes available for multi-zone systems which control the airflow given to individual zones. In comparison to CAV, cold water is continuously flowing to the fan bobbin assembly. In applications where multiple zones with variable load exist, VAV systems reach their maximum potential. Examples include centers, hotels and office buildings.

The function of VAV boxes is analogous to the CAV heaters. The airflow is regulated when the temperature is constant rather than reheating the air to meet the requirements of each zone.

TECNALCO is one of the top VAV manufacturers in UAE.
