Inhaling of healthy and fresh natural air is very important for the human body to increase resistance and immunity of the body. In today time, lifestyle has become such that, maximum hours of the day are spent in closed, air-conditioned setups, whether it’s our home, or local conveyance, office or school. Although these gadgets provide comfort to the body by regulating the temperature, the air which we inhale is very unhealthy and contaminated. This is because air conditioners function in such a way that instead of pulling in fresh air from outside, it keeps regulating the same air shared by many within that room. Natural ventilators have proved to be a better and much healthier option. There are many companies specialized in ventilation systems like airocle, who offer a range of products depending on the need and physical setup.

Natural ventilation systems by taking advantage of the natural force of the wind, as well as due to the difference in the density of air indoor and outdoor, drive outside air into the room through special purpose envelope openings like windows, doors, wind towers, solar chimneys etc.
Two types of ventilation systems:
1. Wind-driven: Here as soon as the wind blowing around the building hits the windward wall, the pressure is created, and the fresh air is sucked into the building through the small opening.
2. Negative pressure systems: especially used in cold areas, where device surrounding the thorax are used in such a way, that the development of negative and subatmospheric pressure causes thoracic expansion.
Certain benefits of natural ventilation systems are:
• Enhances interiors of the house: It brings in more daylight, hence naturally brightening up the house. With the innovative designs of ventilator systems, there is no need of any extra pipework or duct penetration.
• Lowers the consumption of energy: Natural ventilators require less energy to operate as compared to mechanical ventilators traditionally used.
• Full utilization of space: Natural ventilators does not require any extra space for installing special air handling unit or a separate equipment room. Therefore, one can utilize the complete space for their own purpose.
• Reduces carbon footprints: Since these ventilator systems consume minimal energy, therefore the CO2 emission is saved to up to 20-70%.
• Enhances comfort and satisfaction: The temperature maintained inside the building using natural ventilators is very comfortable, and the satisfactory rate of 80% is achieved for the people staying or working there.
• Require minimal maintenance: Unlike other air-conditioning units, there is no need of filter replacement or duct cleaning.
• Reduces the expenditure drastically: The components and the construction procedure for these ventilator systems are much less as compared to other alternatives. The operating and maintenance cost is considerably lower. With the sort of productivity and health benefits it renders, one can expect a return on investment of installing of these units within 1 year of time.
One of the major drawbacks of these systems is, there is a dependency on the external climatic conditions. The prerequisites for the ventilator to work is the availability of wind and the temperature difference.
