Summary
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. 蓝色：新风供给。
- YELLOW Products of combustion.
- BROWN Products of respiration.
- RED Products of respiration from infected scholars.
