At all large plants and enterprises, the required humidity should be achieved. This is a pretty sharp question. Professional air humidifiers of industrial type (PUV) are intended for its solution.
When a person for a long time remains without normal humidified air, he develops health difficulties. This is especially true for employees of enterprises. And there, according to the regulations, the necessary industrial air humidifiers must be installed.
The main methods of their action are as follows:
- Isothermal. The air stream is mixed with the water vapor that the device emits. The appliance must convert the liquid to steam. Similar devices work from the power supply network. In the process, they do not vary the temperature indicators of air.
- Adiabatic. Its basis - water should evaporate naturally into the environment. All work is based on the difference between the partial parameters of the vapor pressure (it is generated above the surface of the water) and the pressure of external air. He “eats” moisture. And it must be converted to steam. For this, air needs a solid amount of energy. This is the reason for its cooling.
Varieties of PUV
Both of these technologies are widely used in practice. Any industrial humidifier operates according to one of these methods. And the types of humidifiers are as follows:
- Heating. Its components:
- heating component;
- capacity for heating water;
- a hose for outputting steam into the duct;
- a tube having holes — it evenly directs the vapor into the air.
Formed steam overheats. Due to this, there is no condensation accumulation inside the device.
- Infrared. The components are the same as in paragraph 1. Only for heating here are the infrared lamps.
- Electrode The bottom line: electrodes are lowered into the water. There follows tension. An electric current appears. Water temperature rises. Water becomes steam.
- Evaporative Water is blown by air and served on a special plastic or paper surface. Due to this, moisture evaporates.
- Splitting. Principle: there is a splitting of water into many tiny particles. They are affected by pressure from a special pump. Then they are distributed in the air. Their evaporation occurs.
- Ultrasonic. This is an innovative technique. Acts on the principle of a membrane. She vibrates intensely. It turns on water and rapidly sprayed onto a huge volume of microparticles. And air follows through it and saturates it with moisture.
Using any of the indicated species, it is necessary to control the purity of the water intended for treatment. This is a measure to avoid air pollution.
Ultrasonic PUV
Today the demand for them is impressive. Ultrasound creates a cloud. It spreads throughout the room. Cloud is converted to steam using a natural method. So the required humidity develops.
To prevent dangerous elements from this cloud from falling onto clothing, objects and various equipment, special filters are arranged in the ultrasonic PUVs. They look like cartridges. If necessary, they can be changed.
When using this type of humidifier, you can carefully control the humidity level in the entire room. Such devices have automatic performance control. The daily parameter turns out more than 10 l. And warm steam can be given out at a modest noise level.
Disadvantages of PUV
- The system has limited capacity parameters. They need a constant addition of water.
- If you do not replace the cartridge after 4 months, then furniture, appliances and other objects surrounding the apparatus will be covered with saline coating.
PUV selection criteria
They are similar to the criteria for choosing household models. The main thing is to get the best and most effective option.
Criteria:
- The volume of the room. Its calculation is easy to do. Its area is multiplied by the height of the ceilings.
- The quality of the water used. The efficiency of the device and the duration of its operational life depend on this aspect.
- The conditions in which the device will be used.
- Power consumption. If the room has a low percentage of humidity, it will take a lot of energy for the operation of the PUV. Therefore, it is wiser to install more economical models. And for the same reason, ultrasonic PUVs are increasingly being installed at enterprises.
- The volume of the water tank. The larger it is, the longer the equipment functions. For industrial premises, the area of which usually exceeds 40 sq.m., a tank of at least 5 liters is needed.
It is also important to know the best and most reliable brands and their products. Next, TOP-5 in the PUV category is proposed.
