Swamp Coolers Vs. Tennessee Climate

In order to determine the suitability of swamp coolers in Tennessee (TN), we need to understand how these coolers function and how they interact with the climate conditions found in this state. A key aspect to consider is the relationship between swamp coolers and humidity.

Suitability of Swamp Coolers in High Humidity Conditions

Swamp coolers, also known as evaporative coolers, operate by evaporating water into the air, a process which cools the surrounding environment. The science behind this is simple: when water evaporates, it absorbs heat, leading to a decrease in air temperature. However, this process is most effective in areas with low humidity. In high humidity conditions, the air is already saturated with moisture, making it difficult for the cooler to add more moisture and thereby limiting the cooling effect.
