Chiller IPLV Calculation

[@alexanderwassie9672]

The chiller efficiency values shown on the IPLV calculation are kW/ton values, not EER. 1 kW/ton = (1/12) x EER

[@MEPAcademy]

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 :)

[@abdulsaleem9044]

could you explain the same for the multiple chiller setup.

[@MEPAcademy]

We'll add that to our list of suggestions. Thanks for watching.

Hi sir Can you please explain parth A and parth B in ASHRAE 90,1 I would be very grateful if you explained it.

[@bunnyman6321]

You figured it out yet?

[@uppulurisri8072]

Thanks for uploading the viedoe At the same time can you please explain Nplv calculation

[@MEPAcademy]

The NPLV calculation is for situations when a single chiller is not intended to operate at standard ARI rating conditions.

@@MEPAcademy 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

[@MEPAcademy]

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
