AFA031 Aeraulic Networks Balance Study Module Didactic Equipment Teaching Refrigeration Training Equipment
I Introduction
Among the ventilation, thermo ventilation, air conditioning installations, the verifications of a correct aeraulic network balance is an essential condition to avoid vane efforts of a correct design: the unbalance of one or more zones might cause the missing satisfaction of thermal loads or of ventilation flows of each served environment.
The module, properly designed for educational purposes, allows the study of a duct network balance with field evaluation of parameters such as the static pressure and the air speed in correspondence of different points of the circuit.
The student will be able to deepen the knowledge on the problems related with the air flow and with the pressure losses.

II Training Program
Study of the components of a ventilation system: fan exhaust grilles, ducts, calibration dampers, supply grilles, etc.
Connection of the different installation components and verification of the system functionality
Field measurements of the static, dynamic and total pressure and of the air speed in different points of the air circuit
Localized and distributed pressure losses
The loss coefficients
Dampers calibration to respect the prescribed values of the room air flow
