Direct Conclusion
An increase in terminal temperature difference usually indicates rising thermal resistance on the heat exchange surface, which may be caused by fouling, slime buildup, or insufficient flow.
Judgment Criteria
- 01
Under normal flow conditions, a continuously increasing terminal difference should be attributed to fouling.
- 02
Recording the trend of terminal temperature difference over time provides clearer insights than a single reading.
