A guide to purchasing the damatajhiz Air Washer Unit

In general, Air Washer Units—which include the body, electric motor, fan, air filter, nozzles, water pump, pan, diffuser, hot water coil, and blades—are installed separately from other air conditioning system parts in a structure. They serve as drip collectors.
In the summer, Air Washer Units can be utilized in places where the relative humidity is less than 40%. Evaporative cooling is how they produce cool air by spraying water into the air as it passes. Similar to air conditioners, heating in Air Washer Units is accomplished by adding a hot water coil to the device's air outlet.

Important points in choosing an air washer

examining the technical instances of the DamaTajhiz Air Washer Unit

Performance of the Air Washer Unit's cooling system throughout the summer:

The summertime functioning of the Air Washer Unit is as follows: first, the volume of fresh air is introduced into the Air Washer Unit, passing through the filtration system to remove any dust, and then the clean air is introduced into the main chamber of the airwasher for cooling. The water is sprayed and powdered in the air washer chamber by putting a pump within the device, pumping water there and then directing it to the water sprinklers and water spray nozzles. This is accomplished by air flowing over the water surfaces and in accordance with the process. The air cools due to water evaporation.

The device's Air Washer Unit's heating capacity (during the winter):

The purpose of an Air Washer Unit during the colder months of the year is as follows: first, water is heated by a heating package device or in the main engine room, and then it is sent (through the return pipe) to the Air Washer Unit's heating coil.
The volume of air travelling over the heating coil surface and the flow of hot water inside the coil both cause an increase in air temperature. The water in the coil's temperature drops at the same time, and at this point, it is reheated in the engine room or the package through the return pipe. In order to ensure that hot water runs continually inside the heating coil, this cycle has traditionally been established throughout the colder months of the year.
It should be remembered that there are two ways to operate the heating system of the Air Washer Unit: mixed air and fresh air (full carpet). In the mixed mode, a portion of the needed air volume is supplied by the environment's air through the return channel, and the remaining volume is supplied by outside air. If there is a complete carpet, all of the needed air must come from the outside, where it is cold and fresh, increasing energy usage and associated costs.

filtering system:

Aluminium air filtration systems are installed in the DamaTajhiz company's variously sized air washers. When air passes through this type of filter, dust and suspended particles in the air are absorbed and as a result, clean air is produced. The structure of this type of filter is such that several layers of aluminium nets with very small openings are placed on top of each other in a sinusoidal honeycomb arrangement.
It should be mentioned that aluminium filters might have four, five, or even seven layers depending on the type of order and project requirements.

Dehumidification:

When the temperature of the water sprayed in the Air Washer Unit is lower than the wet temperature of the entering air, dehumidification is achievable. The dehumidification of the air increases with the temperature of the water being sprayed, making the air cooler as a result.

Corrosion Prevention in Air Washer Units:

Any metal system that uses water must include corrosion control. This includes Air Washer Units. Because they dissolve in water, corrosive gases like carbon dioxide, sulfur dioxide, and others can seriously damage the equipment. All of these components combine to create a weak acid that readily penetrates unprotected surfaces and slowly rots and corrodes the device. This corrosion is evident by a pressure drop in the water spray nozzle. They do this by applying a protective and corrosion-preventing coating to metal surfaces, which raises the pH of the water to roughly 9 in this instance. This pH level avoids the growth of microorganisms inside the Air Washer Unit and the production of weak acids in the water.

Air Washer Unit odour control:

Controlling odours in Air Washer Units is important because they generate cool, comfortable air that is necessary for our comfort. As a result, the air needs to be clear, fresh, and free of pollutants and odours of any kind. The interior surfaces of Air Washer Units, however, typically become sticky after a while and develop an unpleasant odour over time, according to how the Air Washer Units function. They utilize gentle oxidizers, including hydrogen peroxide and bromine, to address this issue.

Control of fluff and oil vapour in Air Washer Units:

Control of fluff and oil vapour in Air Washer Units: In production or manufacturing facilities, oily vapour is created and released into the atmosphere as a result of machinery and industrial equipment operating at high speeds. The operation of the Air Washer Unit system is hampered by oil particles; this issue is addressed by oil separator technologies. These substances are injected, which causes the oil to be separated from the water, deposited on the water's surface, and then overflowed out of the system. The water spray nozzles will become clogged by the oil if it stays in the system, and the system will stop functioning as a result.

Conclusion:

In conclusion, hot, dry environments with relative humidity below 40% during the summer months are suited for evaporation systems like Air Washer Units and Zent. Large structures with high ceilings like sports arenas, mosques, mushroom grow rooms, greenhouses, passenger terminals, educational facilities, movie theatres, chain stores, hospitals, and treatment facilities, etc. are especially well suited for these systems. Compared to compression refrigeration systems (air conditioners and chillers), they are less expensive.
It should be mentioned that these appliances use less electricity than a quarter or even a fifth of what air conditioners and compression chillers do in the same area.

Other technical items in the air washer unit

Dehumidification

Dehumidification in air washers is possible when the temperature of the sprayed water is lower than the wet temperature of the incoming air. The colder the sprayed water is, the more it is humidified and the cooler the air becomes.

Corrosion control in air washers

Corrosion control is a must in any metal system that works with water. Carbon dioxide, sulfur dioxide, and other corrosive gases can cause serious problems when dissolved in water. All of these materials form a mild and dilute acid that easily attacks unprotected surfaces and causes corrosion, and one of its characteristics is a pressure drop in the nozzle. To correct this situation, they create an anti-corrosion coating on the metal surface, which in this case increases the pH of the water to about 9. This pH neutralizes surface acids and delays the growth of bacteria in the air washer system.

Odour control in air washers

The air washer gives air to the outside, that is, where people breathe, so the air must be clean and free of any odours and pollution. Air washers quickly become slimy and smelly. To solve this problem, they use low-smelling oxidizers such as hydrogen peroxide and bromine, so these substances are injected into the air washer system twice a week.

Control of fluff and oil vapour in air washers

The oils that are present in the air steam of factories or production workshops are created from the operation of machines at high speeds. Oil particles disrupt the performance of the air washer system, and these problems can be solved by oil separators. These materials take the oil from the sludge and water pollution, bring it to the water, and take them out of the system by overflowing. If the oil remains in the system, it will clog the water spray nozzles and in this condition, the system will stop working.

Conclusion

Evaporation systems such as Airwasher and Zent are suitable for hot and dry areas. These systems are more economical than compression refrigeration systems (air conditioners and chillers), especially for large buildings with high ceilings, such as halls, mosques, sheds, etc. It should be noted that the cost of electricity consumed by these devices is less than a quarter of gas coolers and compression chillers.

Purchasing an air washer unit

Based on the proportion of internal air flow rate to water sprayed, air washers are categorized into three main groups: 4, 6, and 8.

Class 4 air washer:
The cool air that emerges from the airwasher in a Class 4 airwasher has a relative humidity of roughly 60%.

Class 6 air washer:
The relative humidity of the air that exits the air washer in the class 6 Dematehiz business air washers ranges from 60 to 80%.

Class 8 air washer:
In air washers with class 8 temperature equipment, the air that exits the air washer has a relative humidity of more than 80%.
It should be noted that Class 8 air washers have substantially lower air temperatures than other varieties of air washers because of the greater flow rate of water blasted from them.

Note: Typically, the table below is used to establish the water flow rate needed for air conditioners.

A sort of air washer unit	Rate of aeration (CFM)	Required water flow rate (GPM) for an air washer
CLASS 4	1000	4
CLASS 6	1000	6
CLASS 8	1000	8
