Water Cooler

Buying types of water coolers – introducing the types of this device + advantages and prices

In these hot summer days, the water cooler contributes a lot to creating a suitable and cool temperature. Water coolers are always used in hot summer and spring days. There are different types of water coolers, some of which can be installed at home, and some coolers are portable and can be taken anywhere.

Types of water coolers

Water coolers are divided into two categories:

·       Fixed water cooler

These coolers are often installed on the roof of houses and have great cooling power; But they consume a lot of water. In some of these types of coolers, to bring water to the bags, you have to pour water into the coolers manually, but in others, to bring water to the bags, piping is installed in this device and the water is pumped through a water pump. Water flows automatically by pressing the pump button. These coolers often transfer air through ducts.

·       Portable water cooler

Portable or mobile water coolers, as the name suggests, have the ability to be moved and carried. The tank of this device is either filled manually or it can be connected directly to the hose and faucet.

As we know, in a normal water cooler, cool air is created by water falling on the bags and air passing through the wet bags, and of course, the bag loses its integrity after less than a month, and the bag becomes empty in some places, causing Reduction of cooling efficiency in conventional water coolers.

Cellulose water cooler

Cellulose water coolers use cellulose pads instead of cloth, which provides better and more continuous supply of cool air in cellulose coolers due to the volumetric consistency of cellulose compared to cloth. The use of cellulose pad instead of pushal in water coolers, due to the property of absorbing more water than pushal, as well as the placement of regular, wavy and uniform layers of cellulose together, the uniform distribution of water on the cellulose pad, and as a result, the most effective contact surface between the air The permeability and wet surface of the cellulose pad creates more cooling (about 2 to 3 degrees Celsius more than coolers with a cover) and prevents the transfer of airborne particles and bacteria into the channel of this device.

How to ventilate in coolers

Water coolers whose air outlet or ventilation channel is located on one of the sides of the water cooler, as well as top-ventilation coolers whose ventilation channel is located on the roof of this device.

Water coolers ventilated from above: these water coolers, which are the most suitable choice for installation in the balcony or terrace of residential units, firstly, they have the possibility of cooling the incoming air from all four directions of this device, and secondly, in case of installation in the balcony or terrace, according to Ventilation from above has the possibility of easier channeling. The important thing about setting up water coolers, according to the statistics of electric shocks leading to death in water cooler service, is that before annual or seasonal service, you must turn off the device’s power switch or seek help from experienced service personnel.

Advantages and disadvantages of water cooler

Water coolers, like other types of coolers, have their own advantages and disadvantages. In this section, we discuss the most important advantages and disadvantages of this type of coolers.

Advantages of water cooler

Some of the most important advantages of this type of cooler are:

Reasonable price compared to different types of air conditioners
Very high cooling efficiency
Very low cost of installing and operating a water cooler
Lower electricity consumption of water coolers compared to gas coolers
Easier and cheaper maintenance.

However, water coolers seem to be more energy efficient than other types of cooling devices. This is a big disadvantage for using a water cooler in hot and dry areas where the need to use these cooling devices is very high.

Water coolers are very useful for use in dry areas. One of the most important advantages of this type of coolers is the creation of fresh, cool and clean air in the home.

Disadvantages of water cooler

Other disadvantages related to water coolers include the following.

One of the main problems in using water coolers is their high water consumption. This issue has been considered more especially in recent years because the problem of water shortage has become a big crisis.
If you live in a polluted city, the water cooler is easily exposed to air pollution and dust. As a result, pollutants and pathogenic agents, including bacteria, viruses and all kinds of fungi, enter the house through the cooler air and pollute the air inside the house as well. This is the reason why the use of this type of coolers in big cities such as Tehran is not recommended at all.
The water cooler has only two fast and slow modes; As a result, it is not possible to achieve an ideal temperature for selection in the room environment.
Another disadvantage of the water cooler is related to its pockets, which are filled with dust and fungus. On the other hand, because they are always moist and the sun does not shine into them, they remain and grow for a very long time. In addition, they enter the interior of the house through cool air. As mentioned, this point becomes more important in polluted cities that have a lot of suspended particles in the air.
Installing water coolers requires proper knowledge of ducting.
Ordinary water is used in water coolers, which has problems such as limitation in the amount of cooling, clogging of the pockets, clogging of the pump and causing rust.
Water cooler price
The price of water coolers varies depending on the capacity and brand of the manufacturer. Nevertheless, the range of these prices can be estimated between 1 to 10 million Tomans. Of course, the facilities installed on water coolers also have a great impact on its price. For example, cellulose water coolers have a higher price than regular coolers.

The main components of the water cooler

Water coolers have a different structure from ancient wind deflectors. In general, the main components of a water cooler are as follows:

The outlet channel of the cooler, which is located between the air valve and the tarpaulin, and if it is not exposed to direct sunlight, increases the efficiency of the cooler and brings cooler air into the home.
Internal channels: As their name suggests, these channels are placed inside the cooler and in front of the propeller.
Cooler body-canvas fabric: A healthy canvas fabric can prevent the transmission of cooler vibrations to the outlet channel.
Gutters: The gutter is actually the water inlet and distribution path on the cooler caps.
Big and small money: Big and small money are connected by a belt. This belt has the task of transferring the mechanical force produced by the electric motor to the fan axis. It is very important that big money and small money are aligned.
Floater: The floater always keeps the water level in the cooler tank constant.
Fuse: The fuse is responsible for protecting the cooler against electrical hazards such as overload.
Terminal box: The terminal box is used to create safe and insulated connections from the metal body of water coolers.
Two-speed electric motor: The two-speed electric motor is responsible for rotating the water cooler fan. This electric motor includes the following:
Start capacitor
Power factor correction capacitor
Centrifugal key
Starter coil
Coil away
Fast winding
Water pump with water pump: The water pump is used to transfer water from the tank to the top of the walls of the cooler, where the cellulose pads and pads are located.
Motor belt: As mentioned, the motor belt is used to transfer electric motor power to small and large pulleys. The motor belt is one of the most important parts of the water cooler that must be checked. Any appendages on the engine belt can lead to tearing and shortening its life.
Motor, bearing and fan blades

The water cooler motor is considered the most important part of a water cooler, which can be adjusted in two fast and slow modes. Don’t forget that the higher the motor power of the cooler, the higher its electricity consumption.

In order for the motor power to be fully transferred and not wasted, the bearing of the fan shaft joint must be properly ventilated and the fan must be well balanced. This problem eventually leads to the transfer of shock and vibration to the fan to different parts of the cooler, including the body, and as a result, the performance of the water cooler is affected.

The difference between a water cooler and a gas cooler

Water cooler and gas cooler are different from each other in many aspects. When buying, the question always arises as to which of these two is better. In order to answer this question, we must first look at the differences between water and gas coolers.

The following are among the most important differences:

Difference in cost: The most important difference between these two types of coolers is the cost. The price of gas coolers is about 4 to 5 times that of water coolers. If money is not an issue, choosing between the two becomes more difficult. The next item is the cost of bills. The electricity consumption of air conditioners is very high.
The difference in terms of weather conditions: the place of residence plays a very important role in choosing between gas and water air conditioners. The use of water coolers is recommended in hot and dry areas because they create moisture in the air. Meanwhile, air conditioners can be a better choice for the northern and southern regions of Iran.
The difference in terms of energy consumption: water coolers have high energy consumption. On the other hand, the electricity consumption of air conditioners is high. As a result, the purchase should be done according to the consumption of these two energies.
The difference in terms of clean air: the air conditioner pollutes the outside air and cleans the inside air, but the water cooler has the opposite function. Of course, it is possible to prevent pollution from entering the house by changing the covers and buying new generation water coolers.
Tips on buying a water cooler

Even though home air conditioners no longer look like luxury, their existence is necessary in every home. Considering the types of coolers with different capacities, we should pay attention to which one is suitable for our home or workplace? In the following, we will explain some of the most important points about buying a water cooler.

One of the important and main points that should be considered when buying a water cooler is its dimensions. The dimensions of a cooler also indicate its capacity. As a result, you should first estimate the required capacity of your room and then buy the air conditioner you want.

Another important point is the weather conditions of the place of residence. As mentioned in the part of the defects of water coolers, dust and pollution easily enter the home through the air path of these types of coolers. As a result, choosing a water cooler for installation in polluted areas and big cities is not an ideal option and is not recommended.

Other points that must be considered when buying are:

Whether or not the walls of the residential building are insulated
Whether or not the walls of the residential building are sunny or not
The Floor You Live On – The further you are from the roof, the higher capacity air conditioners you will need.
