Nice one man. Thanks... helped a lot

Glad to hear it!

@11:00, 1% of time is at 100% rather than 25% as you said and likewise until 12% is at 25% loading.

I think we should take full chiller power (Compressor+condensor fan power)

[@chatakondaanil777]

You can do that or even you can consider chilled water pumps and condenser water pumps power too, but the problem here is that you wont be having any reference values to compare your measured value. Where as for only compressor, designed values are provided by manufacturer himself.
