The enthalpy of air is a critical property in psychrometric analysis for HVAC systems because it represents the total heat content of the air. Enthalpy, measured in units like BTU/lb or kJ/kg, includes both the sensible heat, which is related to the dry-bulb temperature, and the latent heat, which is related to the moisture content (humidity ratio) of the air. In HVAC design and analysis, understanding....
