Building Ventilation And Cooling
By: oleg tchetchel
Commonly available practical methods of plants cooling are:
* Exhaust fans or Power Roof Ventilators (PRVs).
To do a satisfactory job of eliminating excessively hot air, it is usually essential to have powered wall and/or roof exhausters. These fans should also help to control air pressure within the building whether it be negative or positive pressure.
* Supply Fans or PRVs.
A large number of buildings use exhaust PRVs to exhaust fumes, smoke, dust or other contaminants unavoidable in the operation of the business. As a result, these buildings are frequently under a severe negative pressure. The solution to the problem of this kind is usually found in the use of supply fans or "make-up" air ventilators.
* Air Circulators.
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. In this way, in addition to amximum benefit from the fresh, cooler air, occupants receive the added comfort of air circulation over their bodies and they are not adversely affected by the superheated air being exhausted from the building.(read

Explosion Proof Ventilators
By: oleg tchetchel
Hazardous location air exhaust / ventilation fan (sometimes called explosion proof) may be required in any area where the presence of flammable gases, vapors or finely pulverized dust in the atmosphere is sufficient to create a threat of an explosion or fire. It may also be required where easily ignitable fibers or flying's are present. The following information is a representative, but is not an all-inclusive, list of the types of locations and operations that require hazardous location air exhaust / ventilation equipment in at least certain areas. Consult the current National Electric Code® for complete and current information.(read

Side Channel Regenerative Blowers
By: oleg tchetchel
Side channel blowers are oilless and have no complicated intake/exhaust valving. Most can be mounted in any plane and, with dynamically balanced impellers, generate little vibration. Because they are nonpositive displacement compressor/vacuum pumps, they discharge air that is clean and pulsation free, which are important considerations for today's plant instruments and controls.(read

Roof Fan Ventilators
By: oleg tchetchel
Simple roof ventilator is essentially an opening in the roof with a cover to keep out rain and to prevent winds from interfering with its functioning. Natural convection is an appreciable aid to ventilation in a large building only if it contains sources of large amounts of heat. A further useful adjunct is a fan fan, device for agitating air or gases or moving them from one location to another. Mechanical fans with revolving blades are used for ventilation, in manufacturing, in winnowing grain, to remove dust, cuttings, or other waste, or to provide draft for a fire. The addition of distribution ducts to the fan and a system for forcing air into the building provides greater efficiency. Outlets are designed to attain maximum mixing of air and to move large amounts of air at low velocity so that temperature layers are eliminated. Factories have special suction hoods and enclosures to draw away localized dust, fumes, and heat. Incoming air may be cleaned of dust by filters or electrostatic precipitators.(read

Aluminum Regenerative Blowers
By: oleg tchetchel
There are four power source choices for regenerative blowers: DC power, AC single-phase, AC three-phase, and engine. Features for regenerative blowers include: control panels and pressure or vacuum gauges. Most control panels include adjustment controls instead of a simple, regulator knob. Regenerative blowers can also have a pressure or vacuum gauge or sensor with a dial or digital readout that monitors the pressure or vacuum levels in the system.(read
