Implementation of enhanced tubes in heat exchangers design has led to the improvement in the thermal efficiency of refrigeration, heating, and air conditioning systems. However, available fouling prediction models are not accurate enough to predict the effect of tube enhancement and water quality on fouling progression inside tubes. This seminar will highlight the result of the experimental study conducted as part of ASHRAE RP-1677 on evaluating the effect of enhanced tube characteristics and water quality on the fouling behavior and propose a model that can predict the fouling by considering the sticking probability and deposit bond strength in different geometries.
