Refrigerated air is like car air conditioning on a much larger scale. It uses a freon type refrigerant and dehumidifies the air. If you live in an area with middle to high humidity, refrigerated a/c cools much better. These can be room units or whole house units/central a/c. Another type of a/c is evaporative coolers. They can also be central a/c installed on the roof or another opening in the house through which the air blown goes through a duct that feeds into the rooms of the house. These units are also known as "swamp coolers". They typically have some type of padding that water wets down. There is a "squirrel cage" that is like a heavy duty fan. It pulls air through the wet pads and the air is cooled down and goes into the house. If the humidy is already high, this additional moisture in the air is uncomfortable. El Paso has very low humidity that does benefit from the evaporative coolers. One of the plus sides of evaporative air conditioning is that it is cheaper to run. The thing is, again, that both of these can be by room only or by central air conditioning.
