Johnson Controls VAV BoxeS

Now available with factory mounted and calibrated BACnet Controllers

VAV systems are vary popular in many modern buildings

• VAV systems contain many zones with diverse airflow needs
• VAV systems are dynamic
• VAV systems have minimum airflow zones

What makes Johnson Controls VAV box performance better than most is

1. Air flow measuring – Velocity sensor

• more accurate to measure the air flow = better control (less hunting) = less temperature variation = less energy consumption
• not easy to maintain accuracy when flow rate is lower, so that is why Johnson Controls use Patented FLOWSTAR Sensor Control

2. Air flow controlling – Flow damper

• Pressure drop across the VAV box
• Less the pressure drop = less fan energy consumption

3. Noise level – Mixing box

• Lower dB rating = quieter the box = more comfortable

4. Controller
