Are Evaporative (Swamp) Coolers Less Efficient in High Humidity?
For most people, keeping cool means staying inside with air conditioning.
But with a TurboKool Unit, keeping cool means staying inside with the TurboKool Evaporative (Swamp) Cooler turned on.
Humidity levels make a big difference in the efficiency of swamp coolers.
How well a swamp cooler keeps your RV cool depends on both the temperature and humidity of the outside air.
The higher the humidity, the less effective evaporation will be as a cooling method.
For example, while the air is at 10% humidity, the swamp cooler can drop temperatures by up to 20 to 30 degrees, while at 50% humidity, the swamp cooler can drop temperatures by about 10 degrees.
TurboKool Evaporative (Swamp) Coolers work best on days when the air is driest (lower humidity).
A Turbokool unit runs on 5 amps of 12v power and/or a 100 watt or larger solar panel or you can just use it to save on your monthly utility bill compared to a traditional air conditioner.
It is helpful to understand that keeping cool with swamp cooling can be problematic in high humidity, since s Evaporative (Swamp) Coolers run less efficiently in more humid conditions.
Evaporative (Swamp) Coolers use evaporation of water to cool the outdoor air.
A high speed fan blows the hot, outdoor air through a wet filter element, which allows the air to absorb some of the filters water as the water evaporates.
Air that is hotter and dryer will absorb more water, therefore keeping your RV cooler.
Finally, the high speed fan circulates the cooled off air throughout your RV.
This cooling process has the potential to lower the temperature of the outdoor air by up to 20 to 30 degrees in low humidity, but in high humidity swamp coolers do not work as well, if at all.
Moreover, when the heat approaches triple digit levels, then the humidity will negatively impact swamp cooling at even lower levels.
When the outside temperature soars to 100 degrees, you’re in trouble if the humidity is much above 25%.”
Swamp coolers add moisture to the air, which while refreshing & cool in dry arid conditions, may feel uncomfortable & hot in high humidity.
