Direct evaporative cooling units or swamp coolers are just as capable as air conditioners in cooling different spaces. Before you decide on investing in these coolers, there are several factors that you should carefully consider. These include, but are not limited to the following:
What Is The Local Climate Like?
Evaporative cooling units work most efficiently and effectively in areas where the air is hot and dry. The level of relative humidity has the greatest impact on the efficiency of these cooler units. It is for this reason that evaporative cooling units may not be the best fit for areas that are very humid. You can expect the best efficiency if the relative humidity in your area is around 60% and even better if it is below that. The lower the humidity, the better your evaporative cooler will work.
Do You Have Enough Water?
Evaporative cooling units require a lot of water. If you live in an area where you experience water shortage every now and then, swamp coolers may not be for you after all. Again, if the cost of water is too high, then the running costs may end up being too prohibitive for you. The bottom line is that you should give serious consideration to the availability and cost of water before investing in a swamp cooler.
Where Will You Be Using The Units?
The operation of evaporative coolers is such that it actually humidifies the air. This is beneficial for alleviating dry skin for people living in dry areas. However, this humidifying effect may be undesirable if you are keeping electronics and other equipment that can easily get damaged when exposed to very humid air. You may want to think of an appropriate covering for these items when the swamp coolers are running.
Do You Have Sufficient Ventilation?
Without sufficient ventilation, the moisture build-up from the operation of the evaporative coolers may make your spaces too damp for comfort. It is for this reason that you should ensure that you keep these spaces well ventilated by popping open the windows and doors. Your system will operate more efficiently, and you can expect to enjoy fresher air thanks to the ventilation.
You should make the decision to invest in evaporative cooling units after careful consideration of the highlighted factors and more. By doing so, you can be sure that you will get real value for the investment that you put towards the swamp coolers.
