VAV systems are now proven to be very energy efficient in providing an optimal indoor climate. The latest standards and requirements for energy efficiency and human thermal comfort make it more and more challenging to design new HVAC systems that complied with these standards. Energy savings can be achieved by reducing primary air volumes to a minimum during reduced load conditions. Induction VAV is the best solution to maintain proper air circulation and comfort levels, reducing the primary treated air to the very minimum. The room air will be induced without the use of an additional fan.

CAV or Constant Air Volume systems are the classic solutions to meet HVAC needs. It is really simple and has become very popular. It’s basic concept is to use a constant supply air volume through the distribution system while heating or cooling air to meet the spaces needs. Mainly there are 3 different types of CAV systems available which are single duct, reheat, and mixed asir.

The basic function of airflow control like constant air volume, static pressure, supply/return balancing etc, are very simple and straightforward in theory. The practical application of these functions, however, is quite difficult due to small magnitudes of the measuring signals.
