Answer 1

A proper answer to your question requires the knowledge if you are located in a high or low humidity area. If you are in a high humidity area then just forget about the ‘swamp cooler’ since it will not work well if work at all. More humidity means less water evaporation and therefore less cooling.

A single window AC for 1200 square feet will require a monster of about over 24,000 btu. Depending on your exposure to sun I would recommend 2-3 (12,000 btu each) or even 3-4 (7,500 btu each) units or any combinations to total 24,000-32,000 btu. Also consider installing ceiling fans.

An evaporative cooling unit trickles water over a honeycombed media and blows air around the media. the water selections up the warmth interior the air because it passes in the time of the media. this manner of cooling basically works properly in low to very low humidity situations and could basically cool the air right down to a temperature drawing near the dewpoint of the air flowing over it. they additionally advance the humidity interior the area so as which would be a project additionally. in case you reside in a climate the place the humidity is above 50% RH, you will not get lots cooling result. They paintings super in barren region climates or bigger elevations yet do not paintings properly in any respect in humid climates like the southeast.
