The Enthalpy Calculator microblock accepts a dry bulb temperature and a relative humidity input and calculates a corresponding value for enthalpy. Enthalpy is a measure of energy inherent in the air. A high enthalpy value indicates a higher air temperature.
In cases where the temperature and humidity input values are very high or very low, the enthalpy calculation can become distorted. If the db input is below 32°F or above 104°F, it may be necessary to substitute additional logic in place of the Enthalpy Calculator microblock. This may also be necessary if the hum input value falls below 0% or goes above 100%.
