The chiller load varies depending on the building load, which of course would be higher in summer months. The calculation is meant to identify the chillers performance at various loads. This allows you to compare one chiller versus another. The IPLV measures performance at the ARI Standard 550/590 conditions, while the NPLV is for non-standard conditions. Here is a good article to help you understand better. mepacademy.com/wp-content/uploads/2020/11/IPLV-Chiller-Performance.pdf
The chiller efficiency values shown on the IPLV calculation are kW/ton values, not EER. 1 kW/ton = (1/12) x EER
Correct, there is a fixed relationship between kW/ton and EER. EER = 12(kW/ton). The chart header should read kW/ton. Thanks.
Thanks! That was really confusing for a second :)
Hi sir
Can you please explain parth A and parth B in ASHRAE 90,1
I would be very grateful if you explained it.
You figured it out yet?
Thanks for uploading the viedoe
At the same time can you please explain Nplv calculation
The NPLV calculation is for situations when a single chiller is not intended to operate at standard ARI rating conditions.

Hi sir
Can you please explain chiller load calculation
And chiller efficiency calculation
Hi sir
Can you please explain chiller load and chiler efficiency calculation

could you explain the same for the multiple chiller setup.
We'll add that to our list of suggestions. Thanks for watching.
