Best Climate for Portable Swamp Coolers

Portable swamp coolers can help cool down your home during hot summer months. They aren't designed to be used in all environments. They will work better in certain areas of the country.

Dry Heat

Swamp coolers are most commonly seen in the mid and southwest regions of the United States. A swamp cooler, or evaporative cooler, works by pulling outside water through the unit, evaporates the water, and expels cooler air. This process works best in areas where the relative humidity is low.

Moderate Humidity

Even in some areas that see moderate levels of humidity, a swamp cooler can be used effectively as a temporary solution to heat. It's not uncommon to see evaporative coolers used in loading docks, warehouses, garages, and animal kennels. While they may not provide complete relief in areas with moderate humidity, they can still be used to lower costs associated with cooling on days that are slightly uncomfortable.

High Humidity

The south east regions and other areas that experience high humidity during the summer months are not going to see much relief with the use of a swamp cooler. If you live in an area that only experiences a few weeks of high humidity, a portable swamp cooler can provide some relief. When the humidity climbs, the swamp cooler won't provide much thermal comfort.

Calculate the Capacity of an Exhaust Fan

There is a lot of math involved to calculate the capacity of an exhaust fan. However, if you measure everything accurately the math shall bring a full and simple answer.

Prepping

The first thing is to measure the dimensions of the room with the exhaust fan-length, width, and height. Next, calculate the room's volume in cubic feet by multiplying height by width by length, and convert accordingly.

Personalize the Math

Now, determine how many times per hour you would like to hear the air being cycled out of the bathroom-the most common number is eight. Next, divide sixty by that number, be it eight or whatever have you. This will establish how many minutes it should take your fan to cycle out the air. Afterwards, divide the volume of the bathroom by the minutes you determined just now. This new number is the minimum rating for your bathroom exhaust fan. Assuming the answer is about eighty, it suggests that the fan has a capacity of a minimum of eighty cubic feet per minute.
