VENTILATION DEVICE WITH VARIABLE PASSAGE OF AIR FLOWS Russian patent published in 2015 - IPC F24F12/00 

FIELD: heating.

SUBSTANCE: present invention relates to the ventilation device. It is made with possibility of control of the trajectories of the first and second air flows for their alternating flowing to the first and second heat-absorbing/heat-transfer objects or from them to ensure heat exchange between these two air flows; at that this device contains the first air channel made with possibility of connection with the first specified object, and second air channel made with possibility of connection with the second specified object; at that the device contains a partition separating the first and second air channels along part of their length; at that the device additionally contains one first air passage between the air channels made with possibility of passage of part of the first air flow from the first air channel to the second air channel, and one second air passage between the first air channel and the second air channel made with possibility of passage of part of second air flow from the second air channel to the first air channel, at that at least one air passage has hole made in the partition.

EFFECT: described device ensures higher throughput capacity of the air flow and easy installation in the ventilation system.
