[Bldg-sim] Chiller Improvement Evaluation

[RobertWichert]

Dear Sebastian,

I start with kW/ton ratings at AHRI conditions from the manufacturer.  
Those are good inputs into the software.  I use Energy Pro, but I 
believe most software can take that as input.

It is theoretically possible to estimate performance with evaporative 
pre-coolers if you have reliable effectiveness and chiller data.

Most programs will allow VFD or multi-speed pumps as well.
