Study materials for industrial systems?

Hello people in the industrial refrigeration industry!

I'm starting as an apprentice in August for a company that services, and installs large industrial NH3 refrigeration systems, heat pumps, cold room, RSW and a whole variety of other systems.

Could you guys give me some tips when starting as an apprentice in this industry? And some books or other information you would recommend me reading?

I'm based in Norway, and the school for refrigeration i went to, we didn't really learn a lot about ammonia systems.

Looking forwards for the replies!

Kind Regards

Hello HvT,
it's good to hear that you are interested in learning. I think a good start is GOOGLE.
