Hello Menbers

Re: Small domestic absorption fridge
Hello, meanu is right, the electrolux cycle contains usually ammonia, water and hydrogen, chrome6 as inhibitor. I had to investigate some of these interesting machines. They vary in mixture, Ammonia/Water 18/82% to 25/75% and the are filled up with hydrogen 17 to 22 bars. I modeled some of the machines in software, it's quite
interesting. So if u want to rebuild one sidkale, be prepared to use Chrome6 (poisonous) as inhibitor or good
steel alloys for production.
******************************************
Has anyone tried using Stainless Steel 316 for the tubing instead of Steel ? Then the need for Sodium Chromate corrosion inhibitor would be solved.
Does Hydrogen leak through the microstructure of Stainless Steel 316.
I know these are difficult questions, but some of you are a lot smarter than me in this area.
Are you still around "zeotrope" ?
Kind Regards
