Hi, I have a question about the compressor map given by the manufacturer.
This map is usually given in a table under different evaporating pressure and condensing pressure. If the compressor speed varies from 100% to 50%, can we continue to use this map?

I did an experiment and found that under lower speed, the compressor power is lower than the number given by the map.

P.S. It is a scroll compressor.

How can I use this map under lower speed conditions?
Thanks you !
