Abstract
A controller for a chiller includes processing electronics configured to detect a plurality of surge events. The processing electronics calculate a point for each detected surge event in at least a three dimensional coordinate system. The three dimensional coordinate system describes at least three conditions of the chiller when the surge event was detected. The processing electronics are configured to calculate a surface map for the at least three dimensional coordinate system using the calculated points. The processing electronics are further configured to control at least one setpoint for the chiller using the calculated surface map.
