I am thinking to use excel spreadsheet published by IES to get performance curve regression.
However, this spreadsheet use not only Part Load Ratio but also use temperature difference as below.
On the other hand, Electric Input to Cooling Output Ratio Function of Part Load Ratio Curve expect only Part Load Ratio for variable.
Are there any way to include chiller temperature difference as variable for Electric Input to Cooling Output Ratio Function of Part Load Ratio Curve?
