How Does It Work


Whether you choose a portable swamp cooler or a large one that can chill your entire house, it is important to understand how it works, as some variables need to be considered. For example, if you place it in an area that isn’t well ventilated, you might end up with a house filled with mold and mildew. However, if used properly, this device can bring real benefits and reduce symptoms that are usually associated with dry air.

Knowing how it works, you can make a more informed selection and get exactly what you need for your house. So let’s take a moment to explore the science, technology, and advantages that lay behind these revolutionary devices.

What is Evaporative Cooling?

As the name describes it, we are dealing with evaporation, the process of turning water from its liquid state to gas. This happens when the water is exposed to high temperatures, in our case when it meets the hot air in the room. The particles that have the highest energy are the first to leave the water, thus resulting in a considerable drop in temperature.

To put it simpler, imagine you use a damp cloth to chill your forehead on a hot summer day. The sensation is wonderful, and the effects of the high temperature are reduced for a while. The whole process implies the water getting in contact with your warm body and gradually turning into gas. This way the temperature around your forehead is lowered and the discomfort reduced.

The Process Explained

These devices may come in different sizes, shapes, and colors, they may use either more or less advanced technologies, but one thing remains the same: the process behind. This means that the basic components are the same, so before jumping to how they work, we should focus first on the parts that make up the whole ensemble.

  • The Water Reservoir
    As we have already stated, the water is the main element of the process, and before plugin the cooler in, you must fill the included recipient with water or, in the case of an industrial evaporator, connect it to a water source through the built-in copper tube. The volume of the recipient can differ from one cooler to another, as they are designed to cool areas with different sizes. So keep this in mind: the larger the room that you need to cool, the higher the volume of the water reservoir.
  • The Evaporative Pad
    Thick and usually consisting of multiple layers, these pads absorb the water and work as filters for the hot air that goes through them. Not only that they cool the air, but capture air particles and some pollutants, improving the quality of the air. Many coolers come with additional filters, specially designed to keep viruses, bacteria, germs, allergens, and mold away.
  • The Fan
    It has a double function: to draw the hot air inside the cooler and to release it after it has been cooled down through the evaporation process. Some models allow you to select the speed of the fan, so you can set the rapidity of the cooling and the level of noise.
  • The Controls
    Usually, you can manage fan speed, oscillating function, or set a timer to reduce energy consumption. However, more expensive models will provide you with an LCD that reads parameters and helps you select the desired values. Other optional features include a remote control, water level control or night light.

Now that we’ve learned the components, explaining the process is easy. You fill the reservoir with water and the pads absorb it (in some cases, a pump is included to make the operation more effective). Then, once you power it on, the fan starts drawing the hot air inside the cooler. The air goes through the water-filled pads and evaporation happens, reducing the air temperature down to 20 degrees. If the cooler includes filters, the microorganisms and air pollutants are removed. The last step implies the cooled air being released back into the room, improving thermal comfort.

The Advantages of Using It

Besides being highly efficient in reducing the discomfort caused by dry air and high temperature, this appliance proves to be an excellent investment, especially when you compare it with an air cooler. Here are its main benefits:

  • It’s less expensive – You don’t have to spend a fortune to enjoy the comfort of the cool air. Even the most expensive evaporators cost less than an air conditioner, and, although they can’t produce refrigerated air, they bring enough coolness to keep the horrid summer heat away.
  • It’s energy-saving – Your power bills won’t be overcharged by this little device, and if you choose to replace your air conditioner with it, you will see a huge difference when it comes to operating costs.
  • It’s environmentally-friendly – It doesn’t release refrigerant gas, which has been identified as a considerable pollutant for the environment.
  • It’s portable – You can take it with you wherever you go. No matter if you need more cooling at the office, or you are traveling through an arid desert, it will keep the temperature and humidity in your room at an optimal level.

Conclusion

If you have to choose between an air conditioner and an evaporative air cooler, the last one is a better solution from many points of view. It is cheap and portable, and it doesn’t use any chemicals that may affect the environment. Furthermore, it won’t only cool your room but will moisturize the air, keeping humidity at a pleasant level.

If you are looking for an air cooler that is small and compact and can fit in an ordinary bag, AEOSBIK Portable Air Conditioner is a wonderful choice. It won’t produce any loud noise, thus you can use it in your bedroom or at work. For bigger rooms, that need a constant powerful airflow to stay cold, a larger air cooler like COSTWAY 23430-CYPE will do the job. If you worry that its size may reduce portability, here is the good news: it comes with universal wheels that are attached to its bottom.

Peodelk Mini Evaporative Cooler is perfect for baby rooms and bedrooms in general, as it is super quiet and won’t disturb your sleep. With a 1-year warranty included and customer service at your disposal, you are looking at a totally free risk acquisition.
