Résumé

The data were taken using 800 ppm calcium hardness water supplied to an operating chiller/cooling tower system. The fouling mechanism is a combination of precipitation fouling and particulate fouling. Fouling data were measured for seven different enhanced tube geometries over a 2500 h operating period. Little fouling occurred until 1300 h. After 1300 h. moderate fouling began to occur in the tubes having a large number of starts. These tubes also provide the highest water-side heat transfer coefficients. The salient finding of this first part of the work is that the potential for fouling increases as the number of starts and helix angle increases.
