What is the ventilation shaft?

The ventilation shaft is an open passage designed to allow air circulation to or from an enclosed space. These shafts are common design and building elements in underground projects of all kinds, including metro, service tunnels, living spaces and mines. They can bring fresh air into space or remove musty or polluted air and often have fans or heating and cooling integrated with their ventilation functions.

For centuries, the man knew that fresh air was a necessity of health and well -being. The mines have long employed ventilation shafts to allow constant air circulation to the deepest areas and bring fresh air to employees at the lowest level, while taking air that has become musty or contaminated with harmful or explosive vapors and gases. While a well -designed ventilation shaft system may not require fans to keep air circulation, most down with ventilation shafts are designed with large fans to helpIt moves with a massive amount of air.

WhileVentilation of mining ventilations is one of the most common uses for ventilation shaft, found in all types of settings, above and underground. Any underground installation will require ventilation to keep fresh air supplied to its workers or inhabitants and to remove or allow to escape the musty air. Metro, military installations, workspaces and even museums are just a few underground structures that require ventilation shafts.

surface buildings often use ventilation shafts to circulate air in otherwise enclosed spaces. Air channels are common in almost every modern building and are used to circulate air as well as to bring heated or chilled air to work, life and commercial spaces of all types. Large, complex ventilation shaft systems integrated with fans and heating and chLaz, you can find in hidden spaces in the walls and ceilings of houses, businesses, factories and skyscrapers.

One type of ventilation shaft, which was as long as one employed fire in the interior is a chimney. These structures are the easiest form of a ventilation shaft, usually a simple vertical column used to carry smoke from a fireplace or stoves up and out of home or other building. While many ventilation shafts work in pairs, one brings air and the other transmitting air out, the chimneys are intended by air and excrete smoke along with it. The air circulation is completed by the air entering the building through windows, doors and other holes.
