The measurement of airflow in ducted ventilation systems. |

Mar. 1979, Vol.16, No.3, p.6-11. Illus. |
| Resumen |
Preventive maintenance aspects of ensuring that ventilation systems continue to function properly: checking whether the air flow rate continues to meet the parameters for which the system was designed; reasons for impaired performance (dirt on fan blades, blocked filters, corroded dampers, leaky ducting); multi-branched systems getting out of balance, some branches handling more or less air than intended; measurement of pressure differences across certain parts of the system; use of coloured smoke tracers to make airflow visible and observe flow patterns outside the system; measurement of air velocities at various points in the system. Techniques and instruments used (Pitot static tube; glass U-tube; diaphragm gauge; rotating-vane, hot-wire, thermocouple and thermister anemometers); general guidelines. |
