Hi guys,
I have this question for many years and searched a lot on it and find no answer yet. while designing a refrigeration system I come up with cooling capacity in a range such as 200 KW in -40/+40. the problem is when I try to select a compressor from any type ( recip or screw) some of the manufacturer seems to be so lazy for providing us with capacity tables foe different refrigerant and temperature conditions, only swept volume of the compressor which means how much refrigerant it could pump such as 1200 m^3/h.
The question is how could I calculate how much volume of refrigerant need to be pumped for a calculated capacity?

I would become so grateful for and guide.
