What kind of equipment belongs to civil air defense ventilation equipment?

Time：2023-11-07

Civil air defense ventilation equipment has an important use in the building, mostly underground garage as the main performance method, internal set up civil air defense door, blocking door, lighting, ventilation, water supply and drainage, communication network and other wartime shelter required hardware. Civil air defense engineering is a special underground building with protection requirements, and its commonly used classification methods are as follows: according to the resistance level, the project can be directly called a certain level of civil air defense engineering; According to the wartime use, it can be divided into command and communication, personnel shelter, hospitals, ambulance stations, warehouses, garages, etc.; According to the usual use, it can be divided into shopping malls, amusement parks, hotels, theaters (halls) and so on; From the engineering construction method, it is divided into two categories: excavation engineering and pit tunnel engineering. In order to reasonably reflect the project cost, the budget quota and project budget are usually classified by the project construction method.

Civil Air Defense Ventilation Equipment

Classification of Civil Air Defense Ventilation Equipment:

The ventilator is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas, and it is a driven fluid machine. Modern ventilators are widely used for ventilation, dust removal and cooling in factories, mines, tunnels, cooling towers, vehicles, ships and buildings, ventilation and induced air in boilers and industrial furnaces, cooling and ventilation in air conditioning equipment and household appliances, drying and selection of grain, inflation and propulsion of wind tunnel air sources and hovercraft, etc. Ventilation fans are divided into axial flow fans, centrifugal fans, and electric foot pedal dual-purpose fans. The fan will send fresh air into the civil air defense project, and at the same time can exhaust the air in the project.

When the fan control box is in the "manual" form, the staff can control the fan according to the "start" button or the "stop" button, and

when the switch is dialed to "active", the fan will start and stop actively according to the active start conditions, without personnel on duty.

The light box is used for the display and alarm of the air quality status inside the engineering bunker, and mainly alarms three kinds of air quality conditions: cleaning, isolation, and poison filtration. The light box uses three colors of lights to warn three different air conditions: clean - green light, isolated - red light, and toxic filter - yellow light.
