VAV B 50 Series
Type: Rectangular / Round
Construction: Galvanized Steel (GI) / Stainless Steel
Application: Light & Medium Duty
Constant Air Volume (CAV) Model B-51 is used in heating, ventilating, and air-conditioning system. In CAV system, the supply air flow rate is constant, but the supply air temperature is varied to meet the thermal loads of a space.
In CAV application the terminals maintain the required constant airflow independent to inlet statis pressure. CAV systems are often used due to their simplicity, low cost, and reliability in small buildings and residences. CAV systems often have on/off control, rather than supply air temperature modulation, to vary their heating or cooling capacities to serve a single thermal zone.CAV systems are usually used in spaces with large open areas having uniform loads like theaters, auditoriums and exhibition halls.
Data
Technical Features:
- Volume control range from 100 to 10% is possible to the
conditioned zone. - CAV with reheat, CAV multizone, and CAV
primary-secondary systems can serve multiple zones
and larger buildings. - Accurate airflow sensing with 2 X 12 points averaging.
- Low Leakage i.e. less than 2% of V nominal at 750 Pa.
- Designed to produce low NC levels with minimal
pressure drop to the system. - Suitable for low temperature primary systems.
- Air volume capacity upto 2800 CFM. Suitable for use as constant volume application
- Electronics control factory supply & mounted.
- Variety of control options available, based on
applications. - Electronic thermostat & actuator provide accurate
mounting control. - Metal encapsulated edges limit fiberglass insulation
erosion into the airstream. - Single-point power connection reduces installed cost.
- Maintenance free.
