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 Michael Thomas Saints Jersey , an improvement in the environment can produce substantial benefits in terms of increased production, 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, it should be exhausted from the building near its source.
SUPPLY COOLER AIR
As a rule P.J. Williams Youth Jersey , 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. 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.
VENTILATION
A very effective way to overcome the discomfort of a hot Andrus Peat Youth Jersey , stuffy room is to create a breeze. The circulation of air over a person's body immediately causes a cooling effect on the skin. When air is passed over a moist surface, 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. This pattern of air circulation is sometimes called "breeze conditioning".
Commonly available prcatical 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 andor 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 Sheldon Rankins Youth Jersey , 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.

In this article I will talk about energy security and why it is important.
Energy SecurityWhat is energy security? International Energy Agency (IEA) defines it as “the uninterrupted availability of energy at affordable prices”. Long-term energy security deals with making timely investments to supply energy in line with a country’s economic developments and environmental needs. Short-term energy security, on the other hand, focuses on the ability of the energy system to react promptly to sudden changes in the supply-demand balance. The focus of this article is squarely on long-term energy security.
As already stated in the previous article, India has been importing more than 100 million tonnes of coal since 2010, the figure rising with every passing year. If the countries that India imports coal from stop giving it coal Drew Brees Youth Jersey , it won’t have enough energy to meet its requirements. On the other hand, if they raise the price of coal, India will have enough energy but not at an affordable price. In either case, its energy security will be compromised.
