VAV systems are vary popular in many modern buildings
VAV systems contain many zones with diverse airflow needs 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
