What is an Evaporative Cooler?

A water cooler is one of the important options for Iranian families to spend the summer season in hot and dry areas, a device that not only cools the air but also does the job of air conditioning well. A water cooler with evaporative cooling, which means producing cool air by evaporating water, can make the hot summer weather more desirable and bearable. Therefore, this device has been welcomed for many years.
Low energy consumption, availability, easy installation, and low cost are some of the most important advantages that have made it still popular among consumers despite the production of various air-cooling products.

Water cooler operation

Water coolers help to cool the air by consuming water and producing evaporative cooling. Actually, by absorbing the heat of the air, the cooler uses it to evaporate the water flowing in the cooler, therefore, the larger the dimensions of the cooler and the larger the amount of water circulating in the cooler, the cooling power of the device increases by the same amount. Evaporative cooling is direct and indirect. Direct evaporative cooling increases with the humidity of the cooled air, but in indirect evaporative cooling, the humidity of the cooled air does not change. Common water coolers are direct evaporative cooling that increases the humidity of the environment, so these coolers are not suitable for Sharjah areas.

In the operation of the water cooler, first, the water is directed from the pan through the pump to the gutter above the water cooler or the cellulose of the water cooler, after the water flows through the fabric of the water cooler and moistens it, the electron passes the hot air over the wet towels and from It leads to the desired space through the channel.

Types of water coolers

Water coolers, like many other electrical and practical appliances, have different types you can buy the most suitable and affordable water coolers according to your needs and budget by receiving advice from our colleagues on the Demathezis site.

Portable or mobile water cooler

These coolers, which are mainly used for small spaces, can be moved and their tank is manually connected to the water source for short periods.

Fixed water cooler

These coolers in different sizes are installed on the roof or outside of the building, they have larger dimensions than portable and mobile coolers and must be connected to a fixed water source. These coolers cannot be moved, besides, ducting must be done for them. These coolers are normal and with a cellulose pad. Its cellulosic type has cellulose pads instead of cloth.

Among the advantages of cellulose water coolers, we can mention a cooling rate, less absorption of sediment, prevention of the transfer of particles, and more cooling than surface water coolers. Water cooler with propeller or axial ventilation fan: Unlike the fixed water cooler, these coolers are installed in front of the window for direct ventilation. One of the significant advantages of these coolers is that it does not have ducts and their price is much lower than common water coolers.

Water cooler components

The cooler consists of three electrical, mechanical, and fixed parts.

• Electrical: motor, water pump, and power switch
• Mechanical: belt, float, and ventilation fan
• Fixed: valves, body and covers, drain valve, and water supply network

Advantages of water cooler

It can be said that among all air cooling devices, water coolers are the most popular and least expensive ones, which, of course, have the advantage of low energy consumption, and at the same time, they bring pleasant cool air to consumers.

Therefore, we can see that in many cities of Iran, of course, minus the Sharjah areas, water coolers are preferred over gas coolers and split air conditioners. This applies to both residential and commercial areas.

Considering that the water cooler can properly ventilate the air, to some extent, water coolers can allow pollutants to enter the indoor environment, so to prevent pollutants from entering the house and room, you can use cellulose pads instead of pillows. Of course, washing the cover and draining the water in the chamber also allows you to prevent the entry of pollutants.

Care Solutions

One of the most important concerns of water cooler consumers is deposits that can be seen in the pan and body of the cooler over time. .. is encountered. Therefore, removing these deposits is one of the important measures that should be considered in the annual service of the device.

Among the most important measures that are considered anti-scaling solutions in water coolers, the following can be mentioned:

• Use of cooler cellulose pads: It is the best solution that prevents the device from getting sedimented, sometimes it is suggested to use these pads instead of cloth. These pads prevent the accumulation of sediments with their network structure.
• Water cooler descaler: This is also one of the very good ways to remove sediment from the water cooler. These scum traps with a special formula are placed inside the water and the cooler pan, and during several months of using the cooler, it prevents the cover and body of the cooler from getting sedimented.
• Use of salt ink or bleaching agents: During the use of the water cooler, you can use salt ink or bleaching agents as often as possible to remove deposits, the important thing in using these substances is to use gloves because these chemicals It is harmful to the skin.
• Use of vinegar solution: This method may not be pleasant for some because of the smell of vinegar, but it is one of the simple and home solutions that can help you use it in fewer periods, that is when the cooler has not accumulated a lot of sediment.
• Changing the cooler water regularly: Although this method may not be like other methods and it takes a little time, it is a simple solution that can prevent the accumulation of sediments by draining the water from the cooler monthly and cleaning it.

Water cooler installation and service

Installation is mainly specialized work, and it is better to use the help of experienced technicians. But air conditioner service is something that you should pay attention to almost every year to improve the efficiency of the air conditioner and increase the lifespan of the device. Therefore, before starting the water cooler every year, you should pay attention to the service of the cooler.

• Cooler pump lubrication
• Changing the cover
• Bearing lubrication
• Providing a shade for the cooler
• Complete washing of the cooler and removal of deposits and rust
• Adjusting the placement of the cooler and inlet and outlet valves
• Float adjustment

Because water coolers are electric, you must be careful with the lubrication, adjustments, and washing of various components. If you feel that you cannot handle it alone in any of these steps, seek help from air conditioner service personnel.

A good water cooler feature

To choose the water cooler you want, you must specify what efficiency you expect from it. But in general, you should always keep a few things in mind:

• The building and the amount of sunlight
• Area and square meter of space
• the amount of energy consumption
• Cost
