color:#1F497D'>The short answer would be no and no.&nbsp; I&#8217;m not aware
of any curve tools or libraries and in my experience if you want to use a
custom chiller curve you&#8217;ll have to build it yourself, with close work
with the manufacturer.&nbsp; To create custom chiller curves you need to have
data for the capacity and efficiency as a function of condenser water supply
and chilled water supply temperatures as well as the kW power draw as a function
of part load and LIFT conditions (Condenser Water Supply Temp &#8211; CHW Supply
Temp).<o:p></o:p></span></p>

Essentially I had to specify the conditions that I wanted efficiency and capacity
numbers for and then the manufacturer was able to use his selection program to
