> The human body loses the ability to cool it self with 100% humidity

I wonder whether there are practical/efficient ways of decreasing humidity in situations like this in closed spaces?

So that you could use a regular fan again to cool yourself by means of evaporation of water off of your skin.

An air conditioner already is a cooler and a dehumidifier. In a closed system, using a dehumidifier and then an evaporative cooler makes no difference. Assuming the electrical input to these is dissipated as heat, it ends up heating the room further.

The cold heat exchanger coil can cause condensation, which dehumidifies, but if the air temperature is 'correct' the AC control thermometer will keep the AC unit off.

So you can have have an 'uncomfortable' environment because the temperature is 22C/70F but the humidity is >70%. This is why separate (whole house) dehumidifiers are often recommended: they have a separate hygrometers that cause the unit to start, regardless of what the temperature is.

Thanks for explaining, I didn't know about separate dehumidifiers used in addition to air conditioners.

Does the human body still depend on evaporating sweat to cool down at 22C? I'm trying to understand why one might dehumidify when it's comfortable at 22.
