5 Things to Consider When Buying an Evaporative Air Cooler

1. Do you live in a climate where an Evaporative Cooler would be effective?

Evaporative cooling is a simple, costeffective method for cooling indoor spaces. However, depending on the climate where you live, evaporative cooling might not be the most effective option for you. Thus, understanding how evaporative air coolers work will help you decide if this is the right cooling solution for you.Evaporative cooling occurs naturally all around us. For example, you feel it when you step out of a pool on a hot day and immediately feel a chill. These cooling effects occur because as dry air passes over water, the dry air will absorb some heat of the water. This absorption occurs when the temperature and vapor pressure of the water attempt to equalize with the air. As a result, water molecules turn into gas molecules and heat switches from the higher air temperature to the lower water temperature. Since the air circulates naturally, the area around it is cooled.To consistently cool your home, residential evaporative air coolers build on this natural phenomenon, using a fan to draw warm, stale air inside the unit, where it passes over water-moistened pads to be cooled. During this process, the air is cooled up to 20 degrees. Then, the cool, rejuvenated air is circulated throughout your environment. Since the cool air is continually circulating and creating a breeze, your ambient temperature can feel four to six degrees lower than the actual temperature.

The key to effectively cooling your home with an evaporative cooler is hot, dry air such as what is found in desert areas like the southwestern United States. In fact, Evaporative Coolers are most effective during the hottest times of the day and when humidity levels are below 50 percent.But When using the evaporative coolers, open the window and let the air can change indoor and outdoor, the cooler effect will be better.

Although the name "Swamp Cooler" sounds like it would cool muggy, swamp-like conditions, these machines would actually be ineffective in warm, humid areas like the southeastern United States because the air is so heavily saturated with moisture. Evaporative coolers tend to work best when relative humidity is 60% or less; however, evaporative coolers can work in humid conditions when they are used in semi-outdoor (loading bays and docks, garages) and outdoor conditions (sporting events, festivals) for moisture evaporation. Because of the potential for moisture build-up indoors, an open window or door is required for use, and not recommended for indoor use in humid climates. For people living in more humid climates who are searching for a cost-effective alternative to traditional central air conditioning systems, consider Portable Air Coolers.

2. How do swamp coolers compare with traditional air conditioning systems in terms of cost-effectiveness, energy efficiency, and environmental impact?

The goal of both of swamp coolers and traditional AC is to cool your space. However, swamp coolers are available at a lower overall price point, are more energy efficient, and are much more environmentally friendly than traditional air conditioning systems. Evaporative air coolers come in a variety of designs and capacities - from the portable air cooler design like those from Moly portable air cooler that can easily be moved from room-to-room to the convenient window mount evaporative air cooler design that saves valuable floor space and covers larger areas. More importantly, many swamp coolers require only minor to moderate setup, such as placement of air filters or window mounting.

The use of simple technology to cool your indoor air helps portable air coolers excel at energy efficiency. When compared to air conditioners that use refrigerated cooling systems, operating swamp coolers costs up to 50 percent less. In fact, a 36-inch evaporative air cooler operating for 8 hours typically costs less than one dollar because the only costs associated with operating it are water and electricity. This is almost three times cheaper than traditional cooling costs.

For environmentally conscious consumers, swamp coolers are an ideal solution for keeping cool without harming the environment. Unlike traditional air conditioners that use refrigerants to cool your home, swamp coolers use a natural process that cools the air using motion and water. This process won't add ozone-harming pollutants or other chemicals to the environment.

Furthermore, swamp coolers actually work best when fresh air is available, such as from an open window or door. This constant circulation ensures that your indoor air is fresher than it would be with traditional air conditioners that require an airtight space to operate. Plus, the evaporative cooling process naturally humidifies dry air - reducing dry air symptoms such as itchy eyes, throat, or skin.

3. What size evaporative swamp cooler will be most effective for your space?

To get the best results from your evaporative water cooler, make sure it is the correct size for your space. For example, an evaporative water cooler that is too small for your area will have to work extra hard to keep the space cool, wasting energy.

The CFM (Cubic Feet per Minute) is the amount of fresh air cycled through your environment each minute. To find the CFM, follow this formula:

Square feet needed to be cooled multiplied by ceiling height (in feet). Then divide this number by 2.

For example, if your room is 450 square feet with 8-foot ceilings:

450 X 8 / 2 = 1,800 CFM

According to the equation, you would need a swamp cooler with a CFM of at least 1,800

4. Are there different types of swamp coolers?

Moly air cooler offers 2 types of residential swamp coolers - portable and window mounted. Both types of evaporative air coolers are designed to cool small to large spaces but not entire houses. A portable evaporative cooler is a great cooling solution when mobility is a factor. These swamp coolers typically come with casters to make moving your evaporative air cooler from space to space simple. Many models, such as the MT-55 Evaporative air cooler or the MT-35 Evaporative air cooler, are lightweight and even easier to transport. Oftentimes, however, lightweight swamp coolers are better suited for personal cooling, operating much like a personal heater. For heartier jobs such as cooling patios, decks, garages, workshops, and other large areas, consider investing in a portable swamp cooler with a higher CFM, such as the portable air cooler. Additionally, if you're looking at outdoor evaporative coolers and practical uses, You can choose the industria air cooler 1.1kw &1.5kW & 3kW, airflow can reach 18000m3/h -20000m3/h -30000m3/h. Or for more information, pls feel free contact us E-mail: info@ moly-tec.com .If your cooling problems are localized to a particular room or area, a window swamp cooler is a great energy-efficient alternative to window ACs. These window-mounted swamp coolers often come ready to install and include the necessary installation hardware. Many models, such as the MT-18S Window Evaporative Cooler, can be easily installed in vertical or horizontal windows.

In addition to versatile placement options, these evaporative air coolers come with a variety of extras including remote controls, fan-only operation, humidifier-only operation, LCD control panels, programmable timers, ionizer options, and much more. With this many options, the task isn't finding a swamp cooler - it's choosing the one best suited for your needs.
