I don't know of any output reports where you can see IPLV. You can calculate it based on the chiller curve you have used and the design condition COP.
Just use the coefficients and the basic bi-quadratic formula to to create a table for the values you need to plot, where X is part load ratio at 100%, 75%, 50%, 25%, and y is chiller lift (ECWT - Design LCHWT). For ECWT, use the values outlined in AHRI Std 550, depending on your condenser type:

Just use the coefficients and the basic bi-quadratic formula to to create a table for the values you need to plot, do the calculation, where X is part load ratio at 100%, 75%, 50%, 25%, and y is chiller lift (ECWT - Design LCHWT). For ECWT, use the values outlined in AHRI Std 550, depending on your condenser type:
Then use the standard IPLV equation, also outlined in AHRI Std 550.

I don't know of any output reports where you can see IPLV. You can calculate it based on the chiller curve you have used and the design condition COP.
Just use the coefficients and the basic bi-quadratic formula to to create a table for the EIRfPLR&dT values you need to do the calculation, where X is part load ratio at 100%, 75%, 50%, 25%, and y is chiller lift (ECWT - Design LCHWT). For ECWT, use the values outlined in AHRI Std 550, depending on your condenser type:
The values you calculate are just correction factors. To get the COP from these correction factors, use the equation:
COP = PLR / EIR Correction factor
Then use the standard IPLV equation, also outlined in AHRI Std 550.

Here is an example table, this has more data than you need for just the IPLV calculation, though:
