Hello everyone
Here's an attachment of the simulation of a refrigeration cycle for butane liquefaction in HYSYS. In this simulation I've used a recycle unit before each compressor. My goal is to optimize this cycle. So I've used HYSYS optimizer and my target function which I'm trying to be maximize it, is the COP of this cycle. I've defined the heater's heat flow as variables for this refrigeration cycle (3 variables) to maximize its COP. My Problem is that I don't know which method is appropriate for this goal (SQP,Mixed,FletcherRevees, QuasiNewton or Box).
