CIBSE's Psychrometric Charts provide a graphical representation of the thermodynamic properties of moist air using the data contained in CIBSE Guide C. The properties presented are dry bulb temperature, specific enthalpy, moisture content, wet bulb temperature, specific volume and percentage saturation.
Psychrometric chart PC01 covers the dry bulb temperature range -10 to 60 degrees C. A second chart, PC02, is also available; this covers the dry bulb temperature range 10 to 120 degrees C.
PC01 is available in both PDF and A3 hard copy; PC02 is available in PDF only.
