evaporation cooling can work may be described by one of our
reference-systems, installed for a commercial tree propagation nursery on
Cyprus in the Mediterranean Sea.
temperatures on Cyprus are usually in the range of +42°C (at 45% rel
humidity); in the inside of a tunnel-growing house without cooling the
temperature reached +84°C (!).
Simple fogging to
saturation lowered the temperature to +39°C.
installation of a fan which sucked off hot air from the upper layers of the
tunnel (also see "Air Movement") the inside temperature was lowered to +28°C with a humidity near
This cooling made
it possible for this nursery to propagate tree-cuttings also during high
summer temperatures; formerly this process was possible only during the
winter season with additional heating.
evident economic profit production was increased from former 16.000 to
140.000 plants per year !
