This 27th IIR Informatory Note provides a state of the art of the simple and practical technology that is Evaporative Cooling.


The current Note describes the applications and conditions under which these processes may offer a technical and economic advantage, and addresses matters such as the:


  • engineering principle and different operating system modes,
  • energy saving potentials that could be made compared to conventional cooling systems,
  • consequences on water consumption,
  • main applications of evaporative cooling (air-conditioning, storage of perishable foodstuffs and pre-cooling).


Due to its low cost and its effectiveness, especially in a hot and dry climate, evaporative cooling should be used more, and this Note provides practical recommendations on the conditions of which this technology could be implemented.
