New Approach to Building Ventilation and Cooling
Industrial Pressure Blower Co. suggests some methods of effective building ventilation and cooling. In the industrial area where there is a high density of employees and many manual operations involved, an improvement in the environment can produce significant benefits in terms of increased production, fewer errors, and a decrease in complaints and absenteeism among staff. In other circumstances, the attentiveness of an audience or student group play a factor in success or failure of the project.
To a reasonable degree of personnel comfort in hot weather, there are three basic factors in the air and coolong system of any commercial or industrial buildings.

Removal of very hot air
The first step in the direction of the management of the hot air porblem is to provide for the removal of very warm air from the building. This heated air mixes with the air frequently in the cooler parts of the building of a global temperature increase production. As heated air is often localized around heat-producing machinery, it must be exhausted from the building near the source.
AIR SUPPLY cooler
As a rule, outside air is significantly cooler temperatures than those in a building. As heated air is exhausted, must be provided to replace it with fresh, cooler outside air. When a high temperature air is replaced by outside air, a significant improvement in the average temperature of the AIT building results. Even where outside air temperature can be in the 80s or 90s, without exception, it is 15 degress to 20 degrees cooler than the air that it replaced. This is a very important improvement to the people affected.
VENTILATION
A very effective way to reduce the discomfort of a hot, boring room to overcome them is a breeze to create. The circulation of air over a person’s body immediately causes a cooling effect on the skin. When air is passed over a wet surface it will evaporate some of the water and thus lower the temperature of the surface. This is exactly what happens when the air circulating on the human body. By creating a soft breeze through a room or area, a large section of cooling comfort is provided for people who need to work. This pattern of air movement is sometimes called “air conditioning”.
Generally available prcatical methods of cooling plant are:
* Exhaust fans of Power Roof Ventilators (PRVs).
To do a satisfactory job of eliminating excessive hot air, it is usually necessary powered wall and / or roof exhausters. The fans should also help to control pressure within the building or a negative or positive pressure.
* Provide fans or PRVs.
A large number of buildings used PRVs exhaust fumes, smoke, dust or other contaminants inevitable in the operation of the business to life. Because of these buildings are often under a severe negative pressure. The solution to the problem of this kind are usually in the use of supply fans or “make-up air fan.
* Air Circulators.
If the exhaust and supply air requirements of a building has been carefully designed and installed, and there remains a high spot of discomfort at work, the problem is usually related to the matter of air circulation. In this way, in addition amximum benefit from the fresh, cooler air, residents will receive the added convenience of air circulation over their bodies and they are not adversely affected by the heated air is exhausted from the building.
