The Importance Of A Wind Ventilator In Providing Good Quality Ventilation-zznba

Arts-and-Entertainment The process of replacing or changing air in any area to provide and ensure high indoor air quality is known as ventilation. Through a wind ventilator, it is possible to control temperature or remove unpleasant smell, moisture, heat, carbon dioxide, smoke, dust and airborne diseases. Ventilation is basically used to remove excessive moisture and odours, introduce fresh air from outside, to keep indoor air circulating, and to avoid stagnation inside. The process of ventilation includes both, the distribution of air within the enclosed space as well as interchange of air with the outside. It is among the most essential factors for maintaining and guarding healthy indoor air quality in edifice. Mechanical forced and natural are the two kinds of method used for ventilating a building. Mechanical ventilation is generally used to control and improve indoor air quality. It helps in controlling contaminants, unpleasant smell and excess humidity through the substitution of outside air. However, much energy is needed in humid climates to remove excess moisture from ventilation air. Natural ventilation, on the other hand, helps in ventilating an edifice with outside air and without taking help of a fan or any other mechanical system. It has reference to the flow of outside air to a building as a result of temperature and pressure difference. There are two different kinds of natural ventilation that are usually used in buildings, named wind driven ventilation and buoyancy-driven ventilation. On one hand wind works as the main mechanism in wind ventilator. Whereas, buoyancy-driven ventilation takes place due to directional buoyancy force that mainly occurs from interior and exterior temperature difference. The ventilation is affected by the impact and speed of wind on a building which also affects the infiltration rates through it and resulted in heat loss or heat gain. The speed of the wind is totally depend upon the height of the building as the speed decreases with the ground because of fractional drag. The patterns of wind leaves a significant impact on the building as it forms areas of negative pressure on the sides and leeward along with the positive pressure it makes on the windward side of a building. Hence, the shape of the building and the local wind patterns plays a vital role in forming wind pressure that will help in driving air flow by its apertures. In more practical terms, wind pressure will vary and change considerably forming turbulence and air flow through its interaction with urban context (structures, edifice) and natural environments (hills, trees). Traditional or ancient buildings and vernacular in different weathers rely majority upon natural ventilation for maintaining and controlling thermal .fort conditions in the buildings. Hence, wind ventilators are very useful as it consumes no electricity and are noiseless. It is easy to install and can easily work for a long time and is superior anti-corrosion, long service life, strong wear resistance, high sensitivity and light weight. The wind driven turbo ventilator are generally manufactured by using the ki.ic energy and potential energy that are hidden in the wind. These wind driven turbo ventilators find use in various production factories for discharging the pollutants as well as gases that are generated during production and can be harmful for the workers.
