Fogging system: what it is, how it works, applications

Fog machines were originally conceived to make the stay in the heat quite comfortable even at air temperatures above 40-45 C. They found widespread use for cooling outdoor summer cafes. They are also used in animal husbandry, poultry farming, greenhouses and plant growing. Fog machines are installed at the objects of textile and woodworking industry, printing houses and even for creation of dust suppression systems at enterprises. What are fogging systems and what are their features?

What is a misting system

The simplest misting system consists of a fan with water sprayed through nozzles. Larger, more powerful and effective misting systems require a pump and a system of pipes, self-sealing fittings and nozzles to spray. Moreover, the smaller the nozzles, the finer the droplets can be produced. This artificial fog helps to reduce the temperature by 10-15 C. All systems are mobile, they can be dismantled and moved to another place.

Pros of

• Ecological compatibility. No refrigerants are used - only pure water is used.
• Possibility to use in any space.
• Neither insects, nor dry hot air, nor dust will penetrate into the created space.
• Benefits for plants, birds and animals.
• Creating a comfortable atmosphere for people to relax.
• Aesthetics and beauty.

Cons

• High costs for both the installation itself and its installation.
• Increased consumption of electricity and water.
• The need to involve specialists in the design and installation.

Types of fogging systems

Fogging systems are divided into two categories: low-pressure and high-pressure devices. Low-pressure systems have fairly large droplets of 100 microns at the outlet. These droplets cannot completely evaporate and the entire surroundings will be wet. This would not be very convenient on the veranda, but in the greenhouse, the incomplete evaporation of the droplets helps to moisten the soil and the leaves of the plants.

In high-pressure systems, the size of the resulting droplets is from 1 to 15 microns. They completely evaporate into the air, everything around them stays dry.

Using mist blowers

Cooling by mist

In open spaces usual air conditioners can not work. Mist blowing systems cool and humidify the overheated, hot air. They reduce dustiness, get rid of unwanted odors and as a result make breathing easier. Fog machines are not so much systems for cooling the air as systems for creating and maintaining a microclimate in a certain area. They are used on terraces and outdoor areas of cafes and restaurants, to create comfort in gazebos and near swimming pools, as well as in hotel inner courtyards.

Fogging nozzles are placed along the perimeter of selected areas thereby creating a kind of curtain of fog. The work of such systems is visible from afar, it attracts customers.

In manufacturing facilities does not make sense to cool the air in the entire room of a large shop. It is easier to create one or more zones with a comfortable microclimate.

Greenhouses and conservatories

Mist control systems help to maintain an optimal microclimate for the cultivation of seedlings, mushrooms and other plants in greenhouses, conservatories and conservatories. Using artificial fog, plants can be supplied with fertilizers and growth regulators, chemical protection and phytohormones.

Microclimate in counters

When unpackaged fish, meat, vegetables and fruits are placed on the shelves and cabinets dehydrated and spoiled. Artificial fog will help moisten and cool merchandise.

Livestock and poultry

Fog machines create the right conditions for animals. Birds do not have a natural mechanism for cooling their bodies. Maintaining humidity and normal air temperature, will help keep numbers in poultry farms.
