Fog systems: what they are, types, applications
- 15.05.2023
Fog is a natural phenomenon when water vapor condenses in the air space in the form of tiny water droplets. Outwardly, such a formation looks like a cloud or a continuous curtain is formed in the immediate vicinity of the earth's surface. Through the use of special equipment, it is possible to create an artificial fog to humidify the air and reduce its temperature. Let's consider some features of fog systems.
Fogging system: scheme and principle of operation
The main purpose of installations for creating artificial fog is to atomize water into finely dispersed particles. For this purpose, water passes through nozzles under high and medium pressure. These elements are located under the ceiling or around the perimeter, as well as in other parts of the facility.
If we consider the structure of the fog machine in detail, we should specify such parts of it:
- high-pressure pump;
- hoses;
- water filters;
- lines;
- spray nozzles;
- fans;
- drain valve;
- control panel.
As auxiliary components are used elbows, couplings, tees. Installation of the system is quite simple and does not require expensive tools and special skills.
The system works according to the following principle:
- the pump supplies water to the tubes;
- the water passes through the tubes to the nozzles;
- nozzles atomize water.
Due to the fine atomization, the water immediately evaporates into the air and cools it down. There is no sensation of high humidity and no condensation on the surrounding surfaces. Nozzles with large openings are used for spraying.
During dry and hot weather, the fogging system lowers the air temperature by 15 degrees. If there is already natural humidity and coolness present, the effect will not be as noticeable. That is why it makes sense to use high and medium pressure systems in different places, depending on the initial conditions and the effect you would like to get.
In addition to cooling the air, fog creates a good microclimate for plants, animals and people. In addition, the suspension of moisture in the air helps to protect against insects, as they are mostly intolerant to such conditions.
Features of system control
Fogging is regulated automatically or in turbo mode. The structure of the system includes a time relay. With its help, the regulation of periods of operation of the system takes place. Nozzles release moisture in the necessary volume at a certain time of day, at a set interval or on a particular day. The humidity sensor reports the lower limit of this parameter so that the system comes into motion. When the upper limit is reached, fogging is switched off.
Where the equipment is used
Fog systems are used wherever it is necessary to cope with stuffiness and heat. These are various public places.
Entertainment facilities and sports grounds
In the premises of a cafe, on a summer terrace, on the beach or pool area, as well as on sports grounds, the microclimate is created by a special arrangement of the system. Nozzles are installed in perimeter frames.
Agriculture
Special conditions are required in greenhouses and livestock farms. A uniform humidification and a comfortable temperature increase the yield and create a good environment for keeping livestock or poultry.
Industry and production
In production and industrial halls artificial fog provides normal working conditions. This is necessary to maintain the well-being of employees and to optimize work productivity.
