The Exergy Efficiency Analysis of An Indirect Evaporative Heat Exchanger

On the basis of the actual temperature variety beside a heat transfer plate ,the exergy efficiency of an indirect evaporate process is analyzed numerically. The effects of a wide variety of parameters such as the velocity and temperature of the air stream,the inlet relative humidity,the wettablity of the plate and the channel width are investigated. The results are useful for the design of an indirect evaporative heat exchanger.
