Evaporative cooling is the conversion of liquid water into vapor using the thermal energy in the air resulting in a lower air temperature.
Swamp cooler temperature.
Portacool evaporative coolers can drop the air temperature up to 30 f when the air is very dry such as arid climates of the southwest where relative humidity is typically 30 or less.
Only an air conditioner can do that.
That said even in hot and humid areas such as houston you can still expect to achieve a 10 f 13 f drop in temperature.
Typically an evaporative cooler will bring the room temperature 10 30 degrees down from the outdoor ambient temperature.
Imagine you and your evaporative cooler are in las vegas and it s 108 degrees outside with a wet bulb temperature of 66 degrees.
Evaporative cooler output temperature look up.
These machines work using a basic scientific principle known for centuries.
However they will not lower the overall ambient temperature in the room.
A i r t e m p e r a t u r e.
A swamp cooler operating at 85 percent efficiency can bring the temperature down to a nice cool 72 3 degrees right in the human comfort zone.
The 15 to 40 f cooler air is then directed into the home and pushes warmer air out through windows.
A swamp cooler will help make the temperature feel approximately 5 15 lower in the area within close proximity to where it is located.
Operate the fan only function if available for 30 to 60 minutes to completely dry the device and media before storing.
96 f and humidity 35 results in an output of 78 f.
A swamp cooler can cool the room to a point where it feels comfortable but don t expect it to make the space feel chilly.
This is a common misconception and important for homeowners to understand prior to purchasing an evaporative cooler.
Evaporative coolers work best with very low relative humidity and hot temperatures.
Evaporative coolers lower the temperature of air using the principle of evaporative cooling unlike typical air conditioning systems which use vapor compression refrigeration or absorption refrigeration.
If the average humidity in your area is 40 50 an evaporative cooler will not work properly.
Namely that as water evaporates and changes from liquid to gas it reduces the temperatures of anything around it.
When you have finished using your swamp cooler for the season drain the tank and water line disconnect the water line and cover the cooler.
