Evaporative Cooling Methods : A Review

Abstract

Now days due to energy crisis and harmful effect to environment, there is more and more urgent need of energy saving in air conditioning and water cooling demands in mainly consideration of all the free cooling techniques. Among them evaporative cooling is well known technique from long time which gives good results and wide number of applications in residential, commercial, agricultural, and institutional buildings to industrial applications like as spot cooling in power plants, foundries, etc. This papers aims to review the recent development concerning evaporative cooling technologies that could potentially provide sufficient cooling effort, reduce environmental impact and lower energy consumption. The authors have reviewed various journal papers and suggested different schemes of classification. The review covers working principle, performance of evaporative cooling technology and also studied direct, indirect and direct-indirect cooling system. The study focusing on investigating the method of cooling, benefits in terms of power consumption, cost saving and various environmental aspects, In addition, certain gap areas are identified that would help researchers in future research.
