What is an air washer?
An air washer is a device used to remove dust and clean the air from various contaminants, reduce or increase humidity, and cool the air. Air washers can be used both independently and in conjunction with other air conditioners as part of an air conditioning system, in order to optimize the air conditions of the desired location for working, certain industrial operations, and living.
Separation of air washer components
The most important components of an air washer differ based on where and how it is used.
However, the most important components of an air washer in both cases, i.e. independent use or use as part of an air conditioning system, include the following:
1- Fan
2- Air purification filter, which can be made of metal or fabric.
3- Multiple nozzles
4- Air diffuser
5- Hot water coil
6- Drip catcher blades
How the air washer works
In the air washer system, first the polluted and dirty air is directed to the inside of the device by a technique located at the end of the device.
Then, after passing through the dust filters, the air that has been almost cleaned enters the water fountain chamber. In this chamber, the air is distributed uniformly and uniformly throughout the chamber by a diffuser. After this operation, all the dust particles and other contaminants present in the air stick to the water powder droplets sprayed by the nozzles inside the chamber, and the air is cleaned of them. Then this clean air exits the device and enters the channels installed in the continuation of the device.
Due to the operation performed on the air (dust collection, fan inside the device, and air heat capture with water droplets), the air that comes out of the device is cold and cool, and if a heating system is used, hot.

Disadvantages and advantages of using an air washer
This section examines the disadvantages and advantages of using an air washer.
By examining and obtaining information about air washers, one can identify their advantages and disadvantages. Including:
1- The amount of electricity that an air washer consumes.
2- The price of the air washer.
3- Examining its efficiency and main application
After reviewing the above points, one can proceed to purchase the most suitable air washer for air conditioning in a building.
Here, we will discuss the most important advantages of the air washer, and then we will discuss its disadvantages and problems.
But what are the most important advantages and advantages of an air washer?
1- Low purchase price compared to other devices
In air washers, due to the lack of a compressor, condenser, refrigerant, etc. in the cooling equipment section, and the small number of fans, coils, and pumps in the heating and cooling system of this device, the price of the device is lower compared to the rooftop unit package and central chiller, and in this regard, this device has become an economical device. And as a result, it is considered one of the most important benefits and advantages of the air washer and has increased its use.
In this device, the cooling process is similar to water coolers. The cooling process in this device is that after the air enters the air washer, water is transformed into powder-like particles by a number of nozzles and sprayed into the air inside the chamber. Since the air particles tend to evaporate, heat is taken from the air and transferred to the water particles. As a result, the outgoing air is cooled.
In heating mode, the heating process uses a number of coils or pipes installed at the back of the device, and hot water enters the air washer, and with the technology inside the device, the air passes through these pipes, causing the air temperature to rise.
2- The air washer’s low power consumption
In air washers, electricity is consumed only for the pump and fan, and since there is no compressor in this device, its consumption is reduced.
3- Very effective filtration function
By installing various filters inside the device (according to the needs of each building), the air can be cleaned of any pollution. As a result, this is one of the most important features and advantages of the widespread use of air washers. Of course, it goes without saying that it is better not to use it in health environments such as pharmaceutical laboratories and hospitals due to the water inside the chamber.

4- Low noise
Due to the lack of a compressor and also the use in the exterior parts of the building such as the roof, the noise of this device is extremely low, and this is also one of the advantages of using this device.

5- Easy maintenance and cheaper repairs than other devices
Due to the lack of expensive parts and equipment in this device, it can be repaired at a lower cost if it breaks down.

6- Very high cooling and heating power in large spaces and buildings
Due to its very high ability to draw air into the device and out of it, this device is the best option for large spaces such as large halls and sheds. Of course, if using an air washer is not possible for you, you can use the most similar cooling device to an air washer, namely Zenet.
Disadvantages of an air washer
One of the most important disadvantages of an air washer is the inability to regulate humidity.
Because this device uses water to cool the air, this device is not useful in areas with high humidity, such as cities located on the coast, and this device is better used in areas with dry climates.
Finally, considering the points mentioned above, choosing an air conditioner depends on your choice and the functionality you expect from it, and with the features mentioned above, one of the options you can choose is an air washer.
