Formula

Condenser approach = condenser saturation temperature − leaving condenser-water temperature.

Assumptions

Both temperatures represent the same operating condition. The entered saturation temperature is assumed correct.

Limitations

This calculator does not verify sensor accuracy, refrigerant pressure accuracy, refrigerant selection, load, condenser-water flow, tower operation, or root cause. Approach alone does not prove fouling, charge problems, flow problems, tower problems, or sensor problems.
