Hi All,

I have an gas powered absorption chiller providing both chilled water and hot water in my model. I modelled this using Chiller:Heater:Absorption:DirectFired. According to the Input-Output reference guide and the the engineering reference guide, the following curves need to biquadratic/bilinear.

"Cooling Capacity Function of Temperature Curve Name" "Fuel Input to Cooling Output Ratio Function of Temperature Curve Name" "Electric Input to Cooling Output Ratio Function of Temperature Curve Name"

However, EnergyPlus does not let me select these curve types presently. I am not sure if this component is functioning as desired. Has anyone else run into the same problem with this component? Any guidance over this issue would be much appreciated.

Thank you,

Raghu
