The design of efficient HVAC systems relies heavily on the accurate calculation of thermodynamic properties of moist air. These properties—such as dry-bulb temperature, wet-bulb temperature, relative humidity, enthalpy, and dew point—are visually represented on the psychrometric chart. For decades, engineers performed these calculations manually; however, the advent of digital computation allowed for rapid iteration and precision.
