DOE-2 modifies the COOL-EIR using several curves COOL-EIR-FT as a
function of outdoor conditions and COOL-EIR-FPLR as a function of
the Part Load Ratio. I suppose you could set those to be constant.
Another way would be to just take the Cooling Load from the SS-D
report and divide that by your constant COP. But my question would
be, why do you want to do that ?<br>

<div>Dear all,
<div>I wonder how to set the COP of a chiller as constant? after
I set the chiller type, the electric input ratio type is
determined, which means the self-made constant curve cannot be
input.</div>
