Most of the chillers have a sizing factor input which can be used to adjust the capacity. You would use 0.33 for three chillers.

Dear Vinay,
One of the idiosyncrasies of autosizing in E+ is that it sizes EACH chiller for the TOTAL load. You may not have noticed that the 2nd chiller never operated, but I suspect that was the case.
You’ll have to size them manually for the capacity you desire. Use the capacity of ONE chiller as the total capacity required for your building.
