this is evaporative cooling, yes it does cool by passing air through waterfall exchanging heat to the water but will only do so much for so little. a more effective way is the aircon water bed where water is conditioned to low temp and travel through the bed to deliver, spot cooling, more direct and effective for bedrooms.
Heat in the room is used to convert water droplets to water vapour. That is, latent heat of evaporation for changing from liquid to gaseous state. So temp of the room will drop. Problem is, water vapor (humidity) becomes higher and higher.
Build a indoor pool with fountain or waterfall.
This may cool down the insides without aircon.with aircon.
The water absorbs the heat from the bottom, which ia cooler, and transfer it to the top.
