Abstract: The ways of evaporative cooling for farm buildings in summer have been developed in the world, including fan-pad, mist-fog, sprinkler and spray-curtain, etc. The recent development of them in application and study is reviewed and evaluated in this paper. The fan and evaporative pad cooling system is regarded as the best one, and is widely used, but it should be improved further. Simultaneously, other ways such as mist-fog system should be studied in China, too.
