I am trying to make a schematic of a provision refrigeration system. Which is running 2 compressors and has 3 fridges. It has to be a simple drawing, with no refrigerant types, hi - low pressure cutouts etc..

Until now I have made a schematic like this:

But it looks like it will not work this way, as we know the temperature depents on pressures. In my schematic the pressures in every fridge are the same = same temperatures in each fridge.

or there is a possibility to fit different size TX valves into each line to achieve different temperatures?

Thanks guys
