Summary

This paper presents a thermoeconomic analysis method based on the first and second law of thermodynamics and applied to an evaporative cooling system coupled to an adsorption dehumidifier. The main objective is to use a method called exergetic manufacturing cost (EMC) applied to a system that operates in three different conditions to minimize the operation costs. Basic parameters are the R/P ratio (reactivation air/process air) and the reactivation air temperature. Results of this work show that the minimum reactivation temperature and the minimum R/P ratio corresponds to the smaller EMC. This result can be corroborated through energetic analysis. It was noted that this case is also that which corresponds to lower energy loss.
