VENTILATION DEVICE AND BUILDING EQUIPPED WITH SUCH DEVICE Russian patent published in 2005 - IPC

FIELD: ventilation, heating or cooling systems.

SUBSTANCE: proposed ventilation device contains at least two impellers passing along one axle or revolution, each being made for suction of ambient air in cross direction over considerable part of length of impeller. It has also motor connected with impellers to provided rotation around said axle, at least one bolding member at each end of each impeller, cover covering holding members and impellers provided with holes to let in and let out of air from impellers. Cover is furnished also with connector to connected cover with holding members. Holding members are made for interaction with connector of cover to connect cover and holding members. Ventilation device can be installed together with heating or cooling pipe. Impellers are made for directing considerable part of air flow from impellers is cross direction along outer surface of pipe and back into ambient atmosphere. Building can contain at least two rooms and at least one of ventilation devices described above. Method of operation of ventilation device includes counteraction to heat transfer owing to natural convection by operating impellers to create convection opposite to natural convection. Holding member which holds at least one pipe in fixed position, pipe being laid in longitudinal direction, is adapted for fixing pipe is cross direction relative to holding member and fixing the pipe relative to holding member with possibility of disconnection. Holding member has open surface through which pipe can be fitted in holding member in cross direction by relative movement of holding member and pipe. System to change temperature in at least two rooms of building contains heating or cooling pipe passing between said rooms. System contains great number of ventilation devices, each being adapted for mounting in each room near said pipe. Ventilation device is adapted to create air flow across pipe and it contains control system to operate each ventilation device to change intensity of heat transfer from pipe into ambient medium by changing air flow rate. Method to regulated intensity of heat transfer from cooling or heating pipe in building having at least tow rooms, heating or cooling pipe passing from first room into second one and ventilation device arranged in each room near pipe includes the following operation: control of ventilation device to create air flow across pipe, control of ventilation device to change air flow rate and thus change intensity of heat transfer from pipe.

EFFECT: improved ventilation of building.
