The advantage of a window unit is it is easy to install. However, it will only cool a room or two. A roof-mounted unit is more efficient, but it’s also more difficult to install. The advantage of a ground-mounted version is you don’t have to worry about your swamp cooler leaking through the roof. Also, this version is easier to perform maintenance on. [2] X Research source
First, figure out the volume of your house. To figure out the volume, multiply your square footage by your inside ceiling height. Next, figure out the cubic feet per minute. Divide your volume by 2 to reach your CFM, which should be enough power to get 30 changes per hour.
An air conditioning ton is a unit of measurement. It refers to how many BTUs of heat the air conditioner can remove in an hour.
The dew point is the temperature at which the water in the air is evaporating and condensing at the same rate. You want a lower dew point because swamp coolers work by evaporating water in the air to cool the room down. The lower the dew point, the lower you can cool. Typically, you can cool down the air to 20 degrees above the dew point temperature without your home getting too humid. You can also use a dew point calculator to calculate the dew point, such as this one: http://www. dpcalc. org/. You need to know the temperature and humidity.
You’ll need 1 to 2 square feet (0. 093 to 0. 186 m2) of open window space per 1,000 cfm, which is the unit’s cooling capacity. You don’t want to open them too far because that lets in hot air.
