A building ventilation system comprising at least one ventilation and heating and cooling unit with increased heat collection

摘要

A building ventilation system (60) containing at least one heating and / or cooling ventilation unit (1), the ventilation unit (1) consists of a passive module (4) containing at least one passive air heat exchanger (29, 30) and an active a module (5) containing at least one active air heat exchanger (35). The passive module (4) is coupled to at least one exterior (32) fresh air inlet and at least one interior exhaust air inlet (31) of the waste air from the interior, its first output (OUTP1) is coupled to the first inlet (INA1) of the active module (5) and its second output (OUTP2) is connected to the second input (INA2) of the active module (5). Each active air heat exchanger (35) contains at least one heat modifier (6) and two separate chambers (22, 23). The inlet (22.1) of at least one first chamber (22) is connected to the second inlet (INA2) of the active module (5) and the outlet (22.2) of at least one first chamber (22) is connected to at least one outlet (34) of the waste air into the exterior (2). The inlet (23.1) of at least one first chamber (23) is connected to the second inlet (INA1) of the active module (5) and the outlet (23.2) of at least one first chamber (23) is connected to at least one outlet (15) of the waste air into the interior (2). The invention is based on that the ventilation unit (1) has a second air duct (11) for supplying additional air from the exterior (2), which at its first end is connected to at least one fresh air inlet (32) from the exterior (2) and at its other end it is coupled to the second input (INA2) of the active module (5).
