Wet Curtain




Wet curtain (curtain) cooling water evaporation process mainly by absorbing heat from the air, the air temperature decrease principle of physics. Supporting the use of negative pressure fan , wet curtain installed on the wall in the closed end or side gable houses, the fan installed on the wall at the other end gable or side of the cooling fan out of indoor air and outdoor air negative pressure generated force flow through porous wet wet curtain surface, the large amount of heat in the air for conversion to force air into the interior to reduce 10-15 C, and constantly introduce indoor cooling.
 


Water
evaporation is a very common phenomenon in nature, Wet curtain cooling is also
used this principle, wet curtain cooling system and the integrated use of
negative pressure fan is the use of water evaporation and the heat transfer
principle of air cooling, fully demonstrated the three elements of water
evaporation heat absorption principle:



Surface
area of 1. water contact with air



2. the
speed of air circulation



3. the
temperature of the water itself



And the
heat absorption efficiency of water is proportional to the above factors



1. in
the pump and under the action of gravity, water flow from top to bottom, in the
wet curtain surface of the fibre formation is equivalent to the total area of
fold type water curtain film appearance area more than 10 times, so the contact
area of the water film and the air is very big.



2. because
of negative pressure exhaust fan caused by the pressure difference, so the air
will soon detour through cooling water, and collided with the water curtain
film, so the heat in the air by the water film wide area rapid absorption.

3. when
the water temperature rises, the evaporation will intensify, the evaporation
will be intensified, and the heat taken away by water will increase. That is,
the cooling effect is more obvious.
