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.
