Intercooler Efficiency
Calculate ambient-referenced charge-air cooling effectiveness.
Starting values are examples. Enter your measurements; results update as you type.
Method & assumptions
Effectiveness = (hot inlet − hot outlet) / (hot inlet − cooling-air temperature). An ice-water system may produce an ambient-referenced value above 100%; enter the actual cooling-medium inlet temperature for a more useful comparison.
