With a water pumps, we raise the water pressure to 60-100 bar and then we spray it through nozzle with 0,15
or 0,2 mm. The water goes into the atmosphere in tiny droplets, less than 20 microns. The droplets are evaporating
instantaneous, leading to the temperature drop up to 15° C.
To be eficient, the system needs an on/of control to avoid the humidity increase.
The pump needs also a electronic discharge valve to take the water out from the pipe during the off cycle; even
the nozzle have a anti-drip system to avoid water leaking when pump stops.
