Refrigeratiion pipes and components diagram needed!

Hi, my friends!
I need piping and components diagram for commercial cold room with one air condenser and one compressor with oil separator and liquid receiver on same level (no-pump down), and with two evaporators (each serve its own cold room at same temperatures and same level, but above compressor). Defrost is not needed (it will be defrosted by leaving fans all time on) since its use will be high temperature.
Does anyone have any diagram so that I don't need to draw my own (little too-busy these days :))?
If anyone could provide such diagram/s, I would be very grateful.
Purpose of diagram is to show how pipes should be layed out (slopes, risers, traps) and what parts are included in such circuit, for some apprentices which I need to guide next week!

This any good ?

More seriously, there is a lot of similar clip-art on the re-owned Sporlan website,
try here and click on Clip Art, lots of pages of schematics and plant items.

Thanks Brian. That could be of some help but I was thinking more like explained here:

Nobody has any project diagram to share with me?
Is this setup, I described, such uncommon?
