    In this research, we focused on dry mist, which is an evaporative cooling system, and examined how to evaluate the effect of the system. The system effect seen in past research focused on the amount of change that the vaporization heat of mist brings to these effects, mainly because of factors such as improvement of thermal environment, energy saving, and influence on the behavior of passersby. In this study, we considered the concept of evaluation the system effect based on the total amount of heat of vaporization obtained from the released mist, while following the evaluation indexes shown in the previous research. We modeled the dry mist system introduced in the virtual block by using computational fluid dynamics and quantified it for each contributor of the effect on the total amount of vaporization heat of the released mist into the virtual block. The vaporization heat which contributed to the mitigation of hot weather environment and reduction of air conditioning heat load is suitable for the explicit installation effect of dry mist. In addition, the ratio of vaporization heat to the total amount is a useful index for determining system performance on the design and operation phases of this system.
