Proper Buildings Ventilating
By: oleg tchetchel
Below is a time-honored approach to a determination of air volume requirements. It is based on the theory that a complete change of air in a room or building should be made at a certain time frequency. The rate selected is frequently an arbitrary decision. It may be based on experience with similar installations or may be established by a health or safety code. Many fan manufacturers have published charts that show recommended rates of air change for typical installations.(read

How To Ventilate Buildings
By: oleg tchetchel
Power roof fans of the type manufactured by CB Fan Co. are very similar in basic design to the wall fans. Size and capacity closely parallel the wall fans. One of the most popular PRVs is the upblast exhauster. This unit utilizes air velocity to expel rain or snow that may try to penetrate into the structure. When the unit is not in service, butterfly dampers effectively seal the opening against the weather. Because of the straight through air flow design, this is the most effective and efficient PRV available.(read

Commercial Ventilation Fans
By: oleg tchetchel
If the exhaust and supply air requirements of a building have been carefully engineered and installed, and there continues to be a high instance of worker discomfort, the problem usually relates to the matter of air circulation. Typical examples of worker discomfort are found in areas where exhaust fans are roof mounted and air supply is through windows and wall openings. Air flow is generally from the window opening to the nearest roof exhauster.(read

Large Commercial Building Ventilation
By: oleg tchetchel
When the air temperature in the occupied area of a room or building exceeds 78° to 82°; most individuals begin to feel uncomfortably warm. The first step toward controlling the problem is to provide for the removal of excessively hot air from the building. This superheated air frequently mixes with the air in cooler areas of the building to produce an overall temperature increase. As superheated air is frequently localized around heat-producing machinery, it should be exhausted from the building near its source. This will prevent some undesirable air temperature increase in other areas. As a rule, outside air temperatures are considerably cooler than those inside a building. As superheated air is exhausted, provision should be made to replace it with fresh, cooler, outside air. Exhaust air in many areas of a building may have a temperature of 125° to 150°. This is usually the case where heat-producing machinery is in use. Similar air temperatures frequently occur near the roof or ceiling where rising warm air is trapped and further heated by the sun load on the roof. When this high temperature air is replaced by outside air, a substantial improvement in the average air temperature of the building results. Even where outside air temperature may be in the 80s or 90s, invariably it is 15° to 20° cooler than the air it replaces. This is a very important improvement to the individuals affected.(read

Commercial Versus Industrial Fan
