Psychrometric Chart

This page helps you experiment with the psychrometric chart. A larger screen (say 24 inches) is recommended. Click on the plot area to inspect thermodynamic properties at various (temperature and specific humidity) co-ordinates. You can plot and explore processes with constant wet and dry bulb temperatures, constant total enthalpy and and constant specific humidity processes. You can model simple air conditioning units .
