Hello everyone, i have some difficulty to find the mathematical model of the object Dehumidifier:Desiccant:NoFans contained in EnergyPlus, even i have went through the documents of "InputOutputReference" and "EngineeringReference". As specified in the document of "InputOutputReference" , the object of Dehumidifier:Desiccant:NoFans allows the users to use either the default performance model or user specified performance model. As i currently i have no user specified model, so i have to use the default performance model.The default performance model is defined in the "InputOutputReference" by a performance curve of the following form:. This equation include many coefficients (i.e. C1, C2,C3 and C15), but the values of these coeffieicnts are not given. These values should be specified or referred at somewhere, but i can not find. Is there anyone can give me some hints to the values of these coefficients. I quite appreciate if anyone can give me some feedbacks. Thank you in advance.
