Understanding the Psychrometric Chart for HVAC Engineers

WebThe enthalpy values shown on the psychrometric chart are at saturation (100% RH and DB = WB = DP). The constant enthalpy value lines are assumed to be along the constant WB temp lines. Theoretically there is a very slight deviation between the constant enthalpy and WB lines that can be ignored in HVAC process calculations. WebThis tool is an Online Interactive Psychrometric Chart.
