The compact ventilation system solves the problem of maintaining a certain microclimate in closed premises, and with minimum energy consumption. The device has a tubular body (2), in which a filter (4), three volume heat exchanger (5) with a heater (6) and a first fan (7) are mounted successively from the external opening (11) to the internal opening (10) of the body (2), the ventilation device has a control unit (8) and before the filter (4) in direction of the external opening (11) of the body (2) there is a second fan (3). Both fans operate separately - the first (7) when introducing air and the second (3) when discharging air from the room. |
