AIRCRAFT AIR CONDITIONING SYSTEM WITH ANTI-ICING PROTECTION Russian patent published in 2012 - IPC B64D13/08 

FIELD: transport.

SUBSTANCE: set of inventions relates to aircraft air conditioning systems. System 1 comprises first line 6 to feed cold air at actual temperature T1_act, second line 14 to bleed air portion from first line 6 at branch point 10 into several zones 2, 4 of aircraft, and first zone feed line 24. Raw cold air at T1_act is fed into first line 6. Cold air portion is vented into second line 14 at branch point 10. Cold air of first line 6 is fed into extra zones located downstream and/or upstream of said branch point 10. Warm air is fed via control valve 12 into second line so that air therein is heated to actual temperature T2_act higher than 0°C. Air portion of second line 14 is fed via first zone line 24 into first zone 2. Warm air is fed via second control valve 26 into first line feed line so that air in first zone feed line 24 is heated to actual temperature Tzf1_act. Air is fed via first line into mixing chamber whereto circulated air is fed.

EFFECT: ruled out icing of aircraft air conditioning system.
