Inter-cooler valve sizing
Hello Everyone
I have a high stage -10°C open Intercooler vessel (A) supplied with liquid from the receiver. The sub-cooled liquid is then supplied to the -32°C surge vessel from where it is pumped to the evaporators. There are 2 low stage compressors -40/-10 which discharge into the Intercooler (A). I am upgrading the control valve on the liquid supply to the Intercooler and need to check the kW to size the valve correctly.
My question is: Do I add the kW’s of the -32 system (evaporators fed from the -32 surge vessel) and the kW’s of the 2 -40/-10 compressors? Or is it a little more complicated than that?
Any help greatly appreciated.
