Why air coolers with water cooling are in vogue in 2022: optimum room temperature through efficient evaporation

A portable air cooler with water cooling is a great option to beat the summer heat. Such a device is perfect for use at home or in the office. This allows you to improve comfort in living rooms or bedrooms without having to install bulky air conditioners. The latter can also drive up your electricity bill and contribute to global warming. Instead, keep your home at the ideal temperature in hot, dry weather with a highly efficient evaporative cooling system. Here’s some information that can help you do just that.

Practical and beneficial air coolers with water cooling against summer heat

High temperatures make it difficult to cope with daily activities such as work or sleep, and can even have a negative impact on health. No wonder more and more people are looking for ways to help get through unbearably hot days with practical air conditioners. Wondering if there is a reliable, convenient, energy-efficient, but affordable solution? Fortunately, the answer is yes! Evaporative coolers, also known as swamp coolers, use moisture to cool air. The device pushes evaporated water through a fan to ventilate a room or other area. The main considerations are ease of use, water tank capacity, airflow quality and overall value of the model in question.

How such devices work

Evaporative coolers are a type of air conditioner in which a fan inside the machine draws hot, dry air through a wet media pad. This hot air quickly heats the top layer of moisture on the pad, causing the water to evaporate and lowering the temperature in the water-cooled air cooler by up to 20 degrees. This cool, moist air is then expelled from the unit by the same fan that draws in the hot, dry air. This creates a constant flow of air from the wet pad and cools the immediate area.

These units do not use as much energy as a conventional air conditioner because they only run one fan. The water for the pad is provided by an internal tank. You then need to refill this when the level gets too low to properly cool the air. So, if this seems like a smart and energy-efficient solution for your home, you can learn more about the benefits of this technology below.

Taking advantage of evaporative cooling

Evaporative cooling is a refrigerant-free alternative that uses significantly less energy. There are many different ways to use natural evaporative processes, but one common solution is to build or buy an evaporative cooler yourself. The method is similar to the small spray bottles with a fan mounted on them that people use to spray water on their faces while battling the heat in the middle of summer. It’s basically the same technology, but on a larger scale. But do these swamp coolers actually work? And if so, why doesn’t everyone use them?

Evaporative cooling is loosely based on an old, time-honored process known as sweating. You may have heard of it. Our bodies automatically cool themselves by releasing moisture through the skin. This moisture is picked up by a pleasant breeze, bringing us back to a more comfortable temperature. A quick run through a sprinkler has the same effect. This is essentially what a swamp cooler does to the air in a room. However, as it turns out in testing, the initial ambient conditions play a big role in how well air coolers with water cooling perform.

Air coolers with water cooling vs. air conditioners

A room cooler and an air conditioner basically serve the same purpose, which is to lower the temperature level in the room, although they do so in different ways and achieve slightly different results. The air conditioner is a device that lowers the temperature by circulating the indoor air in the room over and over again, moving the hot air outside and replacing it with a cooler one. They are instrumental in cooling, far more effective than coolers, but always leave the air much drier than anyone would want. Some have led to the use of a humidifier alongside this device to solve the problem.

On the other hand, water-cooled air coolers work in a completely different way by creating coolness through the evaporation of water. Hot air is blown onto a water-absorbing filter and evaporates, cooling the atmosphere in the process. They need water to cool, and ice cubes can even be added for more effect. The dry air produced by air conditioners is unhealthy compared to air coolers and encourages the spread of infections that thrive in such conditions. In addition, air conditioners are also more expensive to operate, but require less attention than coolers. With an air cooler, water needs to be replenished frequently instead of just letting it run like the air conditioner.

What to consider before buying an evaporative cooler

Before choosing evaporative cooling, consider the different types of units available, as well as the space that needs to be cooled, tank capacity, and features like wheels, a timer, and an air exchange system. In addition, evaporative coolers vary by size, mounting location and the angle at which the cool air exits. Types include portable, window, downdraft, side-discharge and swamp coolers. The way to choose the best air cooler for your enclosed space is to look at the airflow rate measured in cubic feet per minute. This value indicates how much air is circulated per minute in a room.

To determine the correct value for your room, first calculate the area in square feet, then multiply that by the height, then divide by 2. For example, in a room of 200 square feet and a height of 7 square feet, the value required would be (300 square feet x 7 square feet) / 2 = 700 cubic feet per minute. This means that the most effective air cooler for your space will be the one with 700 cubic feet per minute, although coolers with lower capacities may also do well. However, they may not be as effective.

If you live in an enclosed space, placing an air cooler in the same room would be nothing less than unpleasant. This is due to the fact that coolers also add moisture to the atmosphere. If there is no cross ventilation for moisture exchange, the air will be oversaturated with moisture. Therefore, it is best to place air coolers in an external location just outside the room or by a window. Most unit categories are designed for medium-sized rooms at best. If your room is larger, buying a unit with equivalent capacity is the best choice.
