The heat in the air was absorbed by moisture evaporation. It can bring down about 10F from the direct air stream. It is a good way to cool the dry area. Swamp cooler does not require vent like air conditioner.

Air conditioner uses compressor to cool air, and it is a lot more efficient and can bring down temperature based on the thermostat. It removes hot air to outside, and therefore cools the inside air with the refrigerant in the system. However, air conditioner requires the venting kits for hot air removal. Also, air conditioners remove the moisture from the air and keep the humidity level low.

Overall, swamp cooler is a low cost alternative to air conditioner.
