Water cooled chiller part load performance

[ChrisMT]

I'm trying to optimise the sequencing of a new large chiller system as the part-load varies and estimate the annual running cost from based on the projects hourly load profiles throughout the year. Unfortunately the part load data I managed to find was just for a particular chiller from Carrier and then again, this was at constant evaporator leaving water temperature.

Does anyone know of any selection software from any manufacturer which allows you to play around with variables such as evaporator LWT, condenser EWT, possibly also variable evaporator flow.

Some help would be really appreciated.
