4 Thermodynamic analysis --- psychrometric chart The psychrometric chart is a graph that describes the relationships between different thermodynamic properties of air at constant pressure.
A psychrometric chart is a graph of the thermodynamic parameters of moist air at a constant pressure, often equated to an elevation relative to sea level. The ASHRAE -style psychrometric chart, shown here, was pioneered by Willis Carrier in 1904. [10]
Psychrometrics is the study of the thermodynamic properties of air-vapor mixtures and a measure of the amount of energy per pound of dry air. It is the fundamentals to understanding how energy works in an HVAC system. The greatest tool to use in analyzing air patterns is called a psychrometric chart.
