We are the only creature on earth that can condition the basic natural parameters like heat, or cold or wind. We have always regulated them according to our comfort. With the advancement of technology, we happen to control these electronically and with better means. Air conditioners are very popular device and most effective one to control the temperatures. There are different kind of air conditioners available in market. We see some air conditioners which follow the evaporation principle while others follow the vapor compression.
Here we will discuss about the evaporative cooler or swamp cooler.
Best Swamp Cooler & Portable swamp cooler Review
Swamp coolers use the evaporation process of water to lower the surrounding temperature. Here we consider the large enthalpy of vaporization which is very useful in dry weather to lower the temperature. Swamp cooler uses less energy and that reduces the costs eventually. To top the list, the moisture
we get from swamp cooling is an additional benefit in dry environment.
Here we will discuss about the working principles, basic features and some other topics related to swamp coolers.
Evaporative cooler works on the theory that says, energy from air is lost when water is evaporated and this loss of energy cause the reduction of air temperature. The main two parameters that we work on here are wet bulb temperature and dry bulb temperature. Dry bulb temperature is the temperature of the air that can be measured by normal thermometer and wet bulb temperature is the minimum possible temperature that can be reached by evaporation of water.
The difference between dry bulb and wet bulb temperature is the measure of the potential of evaporative cooling. Another factor here we consider is humidity. Humidity is the amount of water preset in the air. Any air contains water depending upon the volume and it can absorb water particles depending upon the humidity. Evaporation works till the air is saturated with water. When the air absorbs the water particles, the change of water from liquid to vapor demands energy that is supplied by the air. This phenomena reduces the temperature of the air and keeps our surrounding cool.
Exceptional features of swamp coolers:
Swamp cooler has some amazing features that are worth mentioning. It will make your home comfortable and help you escape the scorching heat. The basic features that you need to look for in an swamp cooler are described below.
CFM stands for Cubic Feet per minute and it gives us the idea about the amount of water it can circulate per minute. This is important as different size of room needs variable size of coolers. You can easily calculate the required CFM of your room by diving the volume of the room. The volume you can get from multiplying the height with the area. While buying you can easily go for something that exceeds your need by some amount.
Water consumption and tank capacity:
The water consumption of a swamp cooler ranges from 3 to 15 gallons per depending upon the size of the cooler and the temperature of the room. The tank capacity tells you about how many times it needs to get refilled. There are some coolers that comes with hose that allows to connect to a source for continuous supply.
Variable speed options:
Variable speed allows you to control the speed depending on your needs. It will let you control the unit efficiency. The fan only mode will allow you to use the cooler as a fan to the whole house when you don’t need the cooling.
Although the energy consumption of swamp cooler is very low, the motors and the fans still use a considerable amount. So energy efficient models would be best for any households.
Filters are very important features of a swamp cooler as it may create some problem for the allergic people or the asthma sufferers. The pets also get affected by all the moist pads that double because of all the impurities present in the air.
Any ideal filter should come with purifier, ionizer, activated carbon particles for best results.
Easy installation and maintenance:
Installation and maintenance is a big factor while using a swamp cooler. The installing cost should be low and the process should be easy while being the maintenance the same way.
There are some variations of swamp coolers and portable swamp coolers very famous nowadays.
Portable swamp coolers 2016:
Portable swamp cooler are evaporative coolers with same working principle but smaller in size and you can move it anywhere you want. Portable swamp cooler comes with casters that has wheels under it and holds the cooler and helps the owner to take it anywhere. The size or width of the caster depends on the dimension of the cooler. The wider the caster, the better it moves on rough surfaces. They can be kept near water supplies but even if there isn’t one you can easily use it for some hours and it has parts to store the water.
The cooling range of swamp cooler depends on the various factors like filters, air temperature, size of the cooler, power consumption and the mode. Depending on manufactures, the range of cooling changes and you should choose wisely for your house keeping all the requirements on mind.
Comparison between swamp cooler and gas cooled air conditioner?
Swamp coolers and gas cooler air conditioner differ in the working principle along with other fields.
What is gas cool air conditioner?
Gas cool air conditioner is the machine that follows the condensation of the air and takes in the hot air and leaving the cool air inside the room.
How does air conditioners work?
In gas cooled air conditioner process goes something like this: first the hot air goes in to the cooler and come in contact with the internal evaporation coil. When the air passes through the coil, it evaporates leaving latent heat and making the temperature down. After that it passes through the compressor when the air is compressed and is sent to the condenser which is one of the most important part of any gas cooling air conditioner. Then the condensed cooled air goes back through the expansive valve to the room atmosphere and the hot air remaining in the system comes outside.
What is swamp cooler?
Swamp cooler is the machine that follows the phenomenon of evaporation of water to cool down the inside air temperature by lowering the enthalpy which is taken by the water for state change in form of latent heat.
How does swamp cooler work?
In case of swamp cooler, an evaporation pad rests between the water reservoir and the water distributor. The water goes from the reservoir and gets sprinkled on the pad from the distributor. When the hot air comes in, it passes through the evaporation pad and gets evaporated. When the air evaporates it takes energy from the air which effects the enthalpy and lowers the temperature of the room.

Easy to install and you can change its place anytime and use this in different rooms.
If we cannot afford to install something in our rooms permanently then AC is the best choice for us.
If we use ACs in different rooms instead of central air conditioning then we save up to 50% energy.
It is great for humid areas as it dehumidify the rooms and increase the comfort level.
This is easy to install and we can use them in any room.
Use at most 75% less electricity when compare to ACs.
They are cheaper than ACs.
Adds moisture in dry weather and keeps the plants and furniture fine.
It needs to get vented mandatorily.
This is expansive and uses more electricity than evaporative coolers.
Needs great amount of water to continue the cooling process.
Good for dry climates but in humid weather or regions, it increase the level of humidity lowering the level of comfort.
