Hi,

I am attempting to generate ice storage discharge curves using the information given in OpenStudio's description of the quadratic curves. I am having trouble interpreting what general form the curve takes based on the given info in OpenStudio. My goal is to be able to see if I can generate my own curves and see how changing the coefficients affects the shape of the curve and ultimately how it affects my building model.

Does anyone know what variables x and y physically mean for the charge/discharge curves? Does anyone know if x**2 means x^2?

Generally, the curves are functions of how much ice is left in the storage tank (plotted on the x-axis) and effectiveness or cooling capacity is plotted on the y-axis. I am confused why there is x and y indicated for the curve fit.

(I tried uploading a screenshot of the ice storage parameters window but I do not have enough "points to do so")

Thanks
