VENTILATION SYSTEM WITH RECUPERATIVE HEAT EXCHANGER Russian patent published in 2008 - IPC F24F5/00 

FIELD: mechanical engineering; air conditioning and ventilation.

SUBSTANCE: invention can be used for creating comfortable microclimate in residential, office and production rooms. Proposed ventilation system with recuperative heat exchanger contains fan, primary and secondary heating heat exchanger and devices where adiabatic cooling and moistening of plenum air are provided by means of nozzles. Recirculation of water is carried out by pump, and devices are furnished with heat and mass exchange apparatuses with vibrofluidizing bed. Vibrators are arranged in pans of heat and mass exchange apparatuses with head. Each nozzle consists of housing with entry hole, cover, sealing gasket between housing and cover, spring arranged between cover and swirler made in form of cylindrical cup turned upside down and installed with ring clearance relative to housing. Swirler is provided with at least two rows of throttling holes. Two tangential throttling holes are made in each row which are equally spaced over ring wall of swirler. Nozzle insert in form of conical washer with calibrated conical hole coaxial with cylindrical surface of swirler and taper reverse to taper of conical washer of insert is installed in lower part of housing.

EFFECT: improved efficiency and reliability of dust entrapping process by increasing degree of liquid spraying by water sprayers.
