1.0 INTRODUCTION

Ventilation primarily takes two forms – natural and mechanical. Natural ventilation is the process of fresh air entering a building via a window, door or other opening while mechanical ventilation is air that is drawn into the building using machinery (typically fans). Good ventilation is essential to human wellbeing; the provision of fresh air in replacement of stale air maintains the correct levels of oxygen and carbon dioxide in the air, and removes odours, bacteria, excess heat and other atmospheric contaminants. It also prevents condensation, which is caused by excess humidity. The capability of a ventilation system for an individual room is usually measured according to how many ‘changes of air’ it is capable of per hour, that is how many times all the air in the room can be completely replaced. The amount of ventilation required varies considerably depending on what the space is used for; an office will typically need far fewer changes of air than a kitchen or factory.

2.0 OBJECTIVE  To control indoor air quality. Excess humidity, odours, and contaminants can often be controlled via dilution or replacement with outside air.  To know the type of ventilation and how the process begin.

4.0 DISCUSSION A ventilation system is a mechanical structure of connected devices that controls airflow within confined spaces, commonly homes and offices. Its main function is to introduce a constant supply of fresh air, usually from the outside while channeling stale air back out. Fans and pumps are common parts of these systems, as are vent grates and air flow tunnels. In most cases, the major working parts are all built within the walls and ducts of structures. People using the space do not usually see any of the working pieces.

5.0 CONCLUSION The simplicity of the system design must be weighed up against the fact that air requirements may not be ideally accommodated. The total investment costs for the entire system are only slightly less than for a fully variably controlled system, but the energy costs (for heating and cooling of the supply and exhaust air) are very high. The decision in favor of fully variable systems is obvious, because such systems are amortized within 1 to 2 years due to the savings potential of the lower energy and construction costs Lower energy requirements reduce the operating costs and preserve the environment. Lastly, the ventilation is low energy requirement and operating cost but for the first operation to put ventilation take a high costs.
