Ventilation systems
Ventilation and air treatment in commercial buildings

When designing a CMV system, you always have to choose between one of three basic techniques:

• single-flow extraction ventilation ;

• insufflation and extraction ventilation in networks, with independent flow rates (independent double flow);

• double-flow ventilation with heat exchanger recovery.

Each of these techniques has its own advantages, and the choice depends on the purpose of the premises and their environment.
