In order to evaluate whether a wet analysis should be performed, the coil surface temperature from the dry analysis is compared with the dewpoint of the inlet air, which is determined from the control volume inlet air enthalpy and temperature using a psychrometric function.
The change in enthalpy from one state to another can be found by integrating Equation (7).
However, if you still get ice when the outdoor temperature is 15, then you have an enthalpy problem.
Therefore, the optimal high-limit curve is actually a differential dry-bulb temperature curve rather than a differential enthalpy curve between the outdoor air and return air.
