An assessment of the economic and environmental feasibility of evaporative cooling unit

Performance of Indirect Evaporative Air-Conditioning (IEAC) is strongly influenced by the climate conditions and varies widely in different climate zones. This investigation conducts thermal and economic performance analysis of IEAC under climatic conditions of three cities from different zones: Amman, Aqaba, and Berlin. Based on the hourly climate data of each zone, economic assessment of IEAC is estimated using Life Cycle Cost (LCC) and Payback Period criterion according to economic figures from local markets for each location. The results revealed that IEAC is promising technology in the selected climate zones. A well-optimized IEAC can cover 99.98%, 95.26% and 84.83% from annual cooling demand in Berlin, Amman and Aqaba, respectively.
