Everything you need to know about evaporative coolers

Evaporative cooling is nothing more than a natural process that uses water as a coolant. This process is the principle behind all refrigeration equipment, towers and condensers. These devices are used to cool fluids in all types of commercial, industrial and domestic applications. During evaporative cooling, all excess heat is released into the atmosphere through evaporation of water. For this process to take place, contact between the water and the air flow in the heat exchanger is required.

We know that evaporative cooling is ideal for applications that require high temperature lowering capabilities. The advantage of this process over others is that it is possible to lower the temperature without excessive energy consumption. So, This is a very profitable idea from the point of view of energy and saving for the environment.

It is a hybrid device between fan and air conditioner. Fans have been used extensively in the last few decades and are still used very often. Operation is simple: by means of blades driven by a motor, they move the surrounding air to circulate air which helps to cool.

On the other hand, air conditioners work more efficiently, but are more expensive. And the fresh air that the air conditioner provides in summer is very comfortable and pleasant. It is very common to walk into a store and notice the difference between the air in the street and the interior. Many people spend more time in stores just to be cool while shopping.

In this case we are trying to get a hybrid between these two devices. Ideally, the two good things in each should be mixed, without adding to the cost. This is a fairly simple air conditioning system and does not require major installation. It can be placed anywhere in the house, although it requires an important requirement: it has an electrical outlet. There are many aspects that make this air conditioner an excellent choice in dealing with hot summers and high temperatures.

Main feature

On the one hand, we find that the space required is not very large. If needed order a few meters in the room where we will put it. This way we will have better performance. You don’t need an air distribution tube and they vary in size. The ideal is to choose one that is not too heavy to be able to transport it from the room if necessary. So we will provide it whenever we want.

Another thing that is advantageous and should be considered when buying an evaporative air conditioner is its power. We remember that because the higher or lower consumption electric power comes from the equipment. This ultimately affects the invoice price at the end of the month. We must take into account the size of the room when choosing power. If the need for AC is small, around 150W of power is more than enough.

To find out and ensure the quality of the tool, it is recommended not to buy the “white” brand. In this case, be guided by quality brands that have a good track record in the sector and that have helped nourish a group of people. Buying this product should not be considered an expense, but it is more of an investment when it comes to your home air conditioner at a great price.

Regarding its consumption, although it wasn’t something that consumed as little as a fan, it did consume less than the air conditioner. It can be said that the consumption is somewhere in between the two devices. According to experts, evaporative coolers consume five times less electricity than air conditioners. This really makes it a very competitive HVAC device.

The type of atmosphere needed

They are highly recommended for those houses where the atmosphere is dry and hot. It should not be used in places with high humidity, as condensation may form. Although the air in the house is dry, during use it is recommended to provide ventilation of the room with a relative frequency. In this way we will avoid condensation of the air due to excess humidity. In addition, the ventilation keeps the appliance cool again.

When we ventilate and use evaporative air conditioners, we let hot, stuffy air out of the room. At the same time, we prevent the entry of dust from outside.

Its effectiveness depends on the “climate” that exists in each installation site. When the air is dry it is able to lower the temperature between 10 and 12 degrees. This is considered a good cooling rate. On the other hand, if we do it in smoke-laden air, it can only lower the temperature between 5 and 7 degrees. As you can see, its effectiveness drops drastically.

In this case, the drier the environment, the greater the cooling and, therefore, the greater the water consumption.

Location and power

The criterion to consider when choosing an evaporative cooler is knowing your demands. If you need a tool to cool d i outdoors or indoors. This greatly varies the model and power required. It is also important to know the square meters that need to be heated.

If the room where we will meet is about 10-15 square meters, with 100W AC is more than enough. However, if the room is 20 square meters (as is usually a living room), one of 150W of power will be required.

On the other hand, if we take care of the exterior of the air conditioner, you will need a device with more power and a plug to connect it. Some models connect the hose and renew the water. There is a lighter for smaller rooms with 60W of power. We might even meet some USB AC to have it in your office.

Periodic maintenance and reviews need to be carried out to ensure proper use of the air conditioner. It is important to keep them clean and disinfected, as moisture attracts bacteria and fungi. Every year, the water tank must be cleaned thoroughly to maintain its quality. In addition, it is recommended to inspect the appliance after a season of use so that, when stored, it remains in good condition and has not been damaged.
