5.4 Operation of the solar and bypass dampers
The Luba
GL collector system is a constant total air volume system. A bypass damper is
positioned in front of the air intake, in parallel with the hot air exit of the collectors. In order to
avoid summer overheating and to keep the incoming air’s temperature at the desired set point,
the Luba
GL collector system is equipped with a simple control system.
