CO2. learning by doing

[A/C MAX]

Hello to all,

I would like to gain some experience using the CO2 as a refrigerant, my idea is "learning by doing" , and I wondering if you guys have some ideas about this subjet.

I can buy a small CO2 compressor localy from BITZER company, don´t have any specific application in this moment, Im just want to "Run" some CO2 cycle, take some notes, and learn

Any idea before I kill myself?

Best regards
