If you want a highly effective machine to cool your space, then get yourself a Window Swamp Cooler! Not only is this cooler easily affordable but also occupies a very small space in your home. It’s easily mountable on a window. Window cooler is also eco-friendly because it doesn’t emit ozone-destroying refrigerants like traditional air conditioners do.

During the summer period, cooling your home is necessary for your health as well as your comfort. The good thing is that the window unit is kept wholly outside your living room. People who appreciate reduced clutter find this attractive. For you to get cool and refreshing air, you have two options: A window swamp cooler or window air conditioner. When analyzed, they each have their own advantages and disadvantages. Before you can conclude which fit best for you, you should read this article to get more know with the window air cooler .

1.How Does Window Swamp Cooler Work

window swamp Cooler

If you own a home in a low-humidity area, then a window air cooler is ideal for you. It works by letting air pass over a damp pad. The moisture found on the pad evaporates and hence cools the air and adds humidity or moisture. The swamp cooler needs water control and continuous water addition for it to work properly. This appliance is not ideal to install in an area where there exists a lot of moisture primarily.

2. Differences between evaporative cooling and air conditioning

Here is A comparison table for evaporative cooling and air conditioning:

4. Is a window air cooler right for you

First, visit the local building and home improvement store and consult widely. You may be surprised to learn that temperature and humidity levels in your area  allow for evaporative coolers or not.

5. How much do the evaporative cooler lower the temperature

This mostly depends on the levels of humidity and temperature usually experienced in your local area. As we mentioned earlier, evaporative coolers work best in dry climates.

Portable Evaporative CoolerIn the first column of the table below, the figures represent outdoor (dry-bulb) temperatures. Then the numbers in the row located at the top of the table represent outdoor relative humidity (or RH).

The most optimum weather conditions for the efficient operation and functioning of an evaporative cooling system are located in the table’s upper left quadrant. Those conditions displayed in the blue boxes are marginal. Those conditions displayed in the other boxes immediately located under the blue ones are not suitable for evaporative cooling.

6. How to properly size a window air cooler

The rating of window swamp coolers is in terms of Cubic Meters Per Hour (CMH) of air that is delivered in a home. A number of window units range from 4000 to 8000 CMH.

So how to calculate CMH(m³/h) requirement of your window cooler

Size of the window unit

Here is a simpler way to calculate. Follow the example.

Step 1. Calculate the Volume of the House

House Length: 10 meters

House Width: 10 meters

House Height: 3 meters

Volume of the Room: Length x Width x Height = 10 x 10 x 3 = 300 m3

Step 2. Set the Air Exchange Times

Most manufacturers of these air cooling systems advice the provision of enough air moving capacity. Based on the environment, the capacity should be somewhere between 20 to 40 air exchanges per hour. Here’s some suggestions for your reference

Step 3. Calculate the Volume of Air

Air exchange times that will be sufficient for your house: 20 times

Total air volume per hour: 300 cubic meters x 20 times = 6000 cubic meters per hour

SO, The CMH requirement for your cooler: 6000 m3/h

7. How to choose a good window cooler

  • Cooling pads:

cooling pad

The key to the efficiency evaporative coolers lies with the design of their cooler pads, as well as level of humidity in the ambient air.

Aspen pads are more affordable, easier to install and replace, more effective and more biodegradable than synthetic versions. But the latter last longer.

Cellulose cooling pads are also known as honeycomb pads, mostly because they look like a honeycomb. They are thicker in comparison to aspen pads and have low maintenance and a higher life. They cost a little more but are also known to be more efficient.

  • Motor: 

Evaporative coolers are more cost-efficient than traditional AC compressors since they only have to pump air. No compressing of any refrigerant gas. A typical residential swamp cooling motor is just 1/3 to 3/4 horsepower. In comparison, a residential AC compressor is 3 to 5 horsepower. If we also include the AC fans needed for cooling and condensing, then we see that evaporative coolers consume much less energy.

Centrifugal fan vs. axial fans

Air-Flow-Of-Centrifugal-Blower-vs-Axial-Blower

The main versions of centrifugal fans include airfoil, forward-curved and backward-inclined. Axial fans are more efficient (80-90%) while centrifugal versions are about 50-60% efficient. So, if you want to buy an evaporative cooler, consider an axial airfoil fan, especially with the direct drive and the static regain cooling device versions.

  • Overload protection 

The cooler comes with an automatic thermal-overload switch that shuts off its motor if it overheats, then restarts it once it has cooled down. 

  •  Durability

 Its corrosion-resistant polyester protects the cooler’s metallic parts from rust even if exposed to weather elements. 

  • Continuous operation

 By connecting a water hose to the cooler’s water supply, you don’t have to refill it.

8. How to maintain the window air cooler

Window mount swamp coolers are quite easy to service and maintain. Any home-owner with some basic mechanical knowledge and basic tools like an adjustable wrench and a screwdriver can do it. This is unlike the maintenance of traditional ACs that is better performed by expert technicians. Its replacement parts are also easily available and inexpensive. 

• Winterizing your window evaporative cooler

To ensure that air cooler does not rust, turn off the water supply connection, hose out the water pan and clean all the dirt and minerals that have settled in the cooler during the winter months. 

• Regular Change of Cooler Pads

Change Cooling pads regularly Pads are pressed against the air cooler. Leaving old pads that have dirt and minerals accumulated on them can cause the cooler to rust whenever rainwater flows down the cooler and runs down to the pad. To avoid rusting it always good to change pads during the fall instead of spring. Most people who fail the change the pads to save money ultimately have to spend more in the long run as they may have to change the entire cooler instead of just the pads. 

Bonus Tip: How to Manage Your Swamp Cooler’s Water

We recommend to use Filtered Water,Distilled Water,Water Softener. As there are dangers of hard water for cooler.Hard water has a high concentration of minerals and deposits, if not filtered properly, it easy to make water pump gummed up with calcium buildup and will stop working. Owners might find spots on filters ,it could be left behind by hard water. Meanwhile, Mineral deposits from water will build up on filters and pads , as it will remain after water evaporated . Calcium buildup will low the efficiency of the air cooler.

If your evaporative air cooler is working less efficiently due to hard water damage, cleaning can be the most effective way.Calcium buildup and mineral deposits can be dissolved by soaking the pads and filters in vinegar.
