37. Practical Methods of Ventilation
June 22, 2012
Air circulators may be effectively used to boost air velocity through large buildings that have a flow pattern difficult to control. Air circulators are also used to redirect air into occupied areas near floor level. The drawing below illustrates each of these uses in a breeze conditioning system b...

38. Practical Methods of Building Ventilation
June 22, 2012
It is usually wise to locate the exhaust fans near the area where heat-producing machinery is found in the industrial building. This has the very practical advantage of exhausting this superheated air near its source and preventing a heat build-up in other areas. If side wall locations are to be uti...

39. Make-Up Fans
June 22, 2012
Practically all air removed from a building is replaced by outside air at the same rate. Outside air will enter by any means available, when the inside air pressure is less than outside air pressure. This happens when exhaust exceeds supply systems capacity to replenish the building envelope with ai...

40. High Temperature Ventilators
June 22, 2012
In addition to the general construction material of the fan, other considerations can be made to increase the limiting temperature. One of the most critical components of the fan are the bearings. So naturally if the bearings are kept out of the hot airstream they are less susceptible to the effects...
