Adiabatic cooling is achieved by using the same technology as and adiabatic humidifier but is controlled in a different way. When fine water droplets are formed by a spray humidifier or evaporation occurs off an evaporative matrix then the heat energy required to change the waters state from a liquid (water) to a gas (humid air) is considerable. This energy is not contained within the temperature of the water (unlike boiling water t create steam) so the heat energy is taken from the surrounding air which consequently cools the air.
100 kg/hr of evaporated water shall result in 69kw of cooling within the air.
Applications such as data centres, offices, car and print plants plus timber machining areas all benefit from free cooling.
