Summary
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.
