Ventilating Fan Co. has offered a few techniques of effective building ventilation and cooling. In industrial plants where there is a high density of employees and many manual operations involved, an improvement in the environment can produce substantial benefits in terms of increased production Arik Armstead 49ers Jersey , reduced errors, and a decline in complaints and absenteeism among employees. In other circumstances, the attentiveness of an audience or student group may be a factor that spells success or failure for the project.
To obtain a reasonable degree of personnel comfort in hot weather, there are three basic factors that should be provided for in the ventilation and coolong system of a commercial or industrial building.
REMOVAL OF EXCESSIVELY HOT AIR
The first step toward controlling the hot air porblem is to provide for the removal of excessively hot air from the building. This superheated air frequently mixes with the air in the cooler areas of the building to produce an overall temperature increase. As superheated air is frequently localized around heat-producing machinery DeForest Buckner 49ers Jersey , it should be exhausted from the building near its source.
SUPPLY COOLER AIR
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 Joe Williams 49ers Jersey , outside air. When high temperature air is replaced by outside air, a substantial improvement in the average ait temperature of the building results. Even where outside air temperature may be in the 80s or 90s, invariably it is 15 degress to 20 degrees cooler than the air it replaces. This is a very important improvement to the individuals affected.

When air is passed over a moist surface C.J. Beathard 49ers Jersey , it will evaporate some of the moisture and thus lower the temperature of the surface. This is precisely what occurs when air circulates across the human body. By creating a gentle breeze throughout a room or area, a great deal of cooling comfort is provided for individuals who must work there.

* Exhaust fans or Power Roof Ventilators (PRVs).
