Calculate moist air enthalpy (kJ/kg). Use total heat content analysis for precise energy modeling, HVAC coil sizing, and thermodynamic system design. Understanding the total energy state of air is critical for designing efficient cooling and heating cycles in commercial buildings.
Sensible heat is the energy that changes the temperature of the air. Latent heat is the energy required to evaporate or condense water vapor in the air.
Engineers calculate the difference in enthalpy between the return air and the supply air to determine the total cooling capacity (kW) required for the coil.
In the Metric system, it is kJ/kg (Kilojoules per kilogram). In the Imperial system, it is BTU/lb (British Thermal Units per pound).
