The invention is designed for the actual needs of the sufficiently efficient ventilation device, which will on the hand allow being minimised to the extent where during the first installation or the replacement of windows in the event of renovation of buildings, it can be installed either into the window frame (91) or optionally mounted into the building wall directly near this frame (91), and will on the other hand efficiently contribute to the substantial improvement of the energy balance of the respectively ventilated building. In general, this type of ventilation device comprises the housing (1) with the counter-flow heat exchanger, comprising the primary part, which is connected with the outer inlet (11) for the supply of air into the housing (1) and the inner inlet (13), which is intended for the supply of air from the device into the respectively ventilated room, and the secondary part, connected to the inner outlet (14) for the discharge of air from the room into the device and also to the outer outlet (12) for the discharge of air from the device into the surroundings of the respectively ventilated building. |
