English: MECHANICAL VENTILATION ON THE DOWNDRAUGHT SYSTEM, BY IMPULSION, OR THE 'PLENUM' PRINCIPLE, APPLIED TO SCHOOLROOMS.
  • A Roof Ventilator.
  • B Main Upcast Shaft.
  • C Horizontal Foul Air Trunk.
  • DD Connecting Pipes from Foul Air Flues.
  • EE Foul Air Flues.
  • FF Foul Air Exits into Flues EE.
  • GG Fresh Air Supply Flues through which the air is mechanically projected at a high velocity up on to the ceiling and then descends, escaping at Exits FF into Flues EE.

N.B. The fresh air supply heated to such a temperature, as is necessary to effectually warm a building, is thereby seriously deteriorated for breathing purposes, therefore to secure healthy ventilation the heating of a building should always be separate and distinct from that of the air supply.

  • BLUE Fresh air supply.
  • YELLOW Products of combustion.
  • BROWN Products of respiration.
  • RED Products of respiration from infected scholars.
