Evaporative cooling: functioning principle
This air cooler uses the evporative cooling system. Its a simple method used since antiquity is hot and dry countries, for its also a cheaper yet efficient technique.
We replicate the evaporation phenomenon <hich can be observed in nature.
Hot and dry air is vaccumed and goes through a humidified media to be cooled. The necessary energy for evaporation is extracted from air and therfore refreshes it. This process is called Adiabatic (constant -pressure enthalpy), since it does not bring nor get heat back.
