Dehumidifier Temperature affects relative humidity and Air Temperature
The dew point is the amount of water water in the air, relative to full saturation of the air. With little change in the temperature, the air has to lower relative humidity. In a 60°F room, the humidity drops to 48% without water being removed.
What is humidity?
Humidity is the amount of water vapor in the air. It is measured by exposing a “saturated” cake of salt to the air and recording how much it loses weight over time. This is called a psychrometer, and will be used to measure relative humidity (RH) at any given temperature.

Do dehumidifiers cool rooms?
Even the biggest commercial dehumidifiers don’t cool a room. In short, a dehumidifier is an electric device that (besides everything else) also produces heat. In an isolated room, heat can’t escape. More heat in a room will increase room temperature. Every physicist and HVAC expert is crystal clear on the dehumidifier raising the room temperature.
