Big HVAC is shaking: Beat the heat with a wet towel and spite for $240B [video]

Big HVAC sells giant towels (fill) with fans blowing on them in a steel enclosure, they’re called evaporative cooling towers.

Evaporative cooling works a lot better if you reject the heat outside of the conditioned space, like outside for example. That’s why there are commercial and industrial pre-packaged cooling towers that are widely available, vs a paper towel and box fan.

This is evaporative cooling. It works well enough if the humidity is low.
