How To Choose Between A Swamp Cooler And Air Conditioner


Swamp coolers and air conditioners are both superior air conditioning appliances. Most home owners face difficulty deciding on which to purchase. They both makes a home environment conducive through altering the interior humidity and air temperatures and creating an artificial interior environment. A swamp cooler brings a cooling effect to the home through the principal of water evaporation and a smooth controlled air flow. It therefore adds humidity to the air and this is accompanied by the cooling effect. It is also referred to as evaporative cooler. On the other side, air conditioners use air refrigeration process to create artificial cool breezes. It uses a refrigerant liquid which takes away heat with it as it evaporates. It then condenses the water vapour in the air and allows between 60% and 50% water vapour composition in the air that enters the house.



Though air conditioners are quite common in homes, swamp coolers have proved to be more efficient not only in creating a better air condition but also in terms of expenses. The following are some of the advantages of swamp coolers over air conditioners:

1) Considerably lower electricity consumption: the most standardized air conditioner uses four times as much electricity as the swamp cooler. If having multiple air conditioners then, you are likely to suffer multiple electric bills as compare to using the swamp cooler. Considering they have an almost similar result: why incur the expenditure?

2) Low cost of installation: unlike air conditioners, swamp coolers are made of simple and even locally available parts. These include; a pump, a pad which can be rigid metal or fiber, a blowing fan, a metal sheet box and a metal sheet box. All these are available at your nearest town. Right?

3) They are eco-friendly: Air conditioners use an evaporative coolant liquid just like a fridge while swamp coolants depend plain water to make air more humid. Their low consumption of energy also saves the environment much depletion in electrical production in the long run.

4) Low maintenance cost: maintaining a cooler is considerably cheap due to the low energy and water consumption, to cheap, readily and locally available repair services. Due to their simplicity, repairs and maintenance such as dusting and dirt removal is easy. The pads which require spontaneous renewal are also locally available.

However swamp coolers have their own shortcomings that makes them inappropriate in some geographical areas and climatic conditions. Such weaknesses include:

1) They cannot be used in extremely humid areas: the aim of any air conditioner or swamp cooler is to create an internal condition that is friendlier than the exterior. When it’s humid or raining therefore, the swamp coolers humidity cause uncomfortable atmosphere.

2) Its consumption of water is considerably high: In an hour, it consumes about 3.5 to 10 water gallons to create the artificial humidity. So what about when there’s a water shortage, or in extremely dry areas which in fact require such a cooler more?

Once you have accounted for all the above advantages and limitations you can now decide on what to install at your home. There are several types of swamp coolers:

a) Direct swamp cooler: pumps air through a wet pad into the home. Air get humid, cool and clean in the process.

b) Indirect swamp cooler: they bring the cooling effect but instead dehumidify the air entering the house. They have a more progressed and comprehensive system that regulates the amount of water vapour or humidity entering the house.

Common and much superior brands of both direct and indirect coolers are; The Edgestar portable evaporative cooler which sells at $ 122.25 and the Edgestar high velocity portable air cooler going at $ 189.05.

Air conditioners too come in four types depending on the position of installation:

a) Portable air conditioners: Operate from the floor and are freestanding. Pull in cold air, dehumidify it and exhaust warm air hence mist be close to an opening.

b) Window air conditioners: Can be installed on top of a window or a specifically designed wall hole. Has a hot air exhauster that should face out through the window or the wall hole.

c) Through the wall air conditioners.

d) Ductless mini- split system air conditioners: are complex and have the condenser installed outside and internal blowers that supply air.
