The Ammonia problem... Answered
I am still trying to build a half decent absorption fridge/freezer for the hot summer days down here.
Usually anhydrous ammonia and water is used for these old style systems.
Problem is that destilling it at home is not the nicest thing, especially in the currently hot weather.
So I called up a few refrigeration guys to inquire on the price of some Ammonia if they fill the system for me instead.
No matter how I try these guys will only fill certified systems but nothing build in your backyard that is missing the required certifications.
Not even for a proof of concept to see if it is working and the gas removed when done with that.
Was also informed that making or just having highly concetrated or even anhydrous ammonia would require that I obtain a permit first :(
What are the alternives for R707 or Ammonia in an old style "Icy Ball" system?
Small question: Has anyone done it and is willing to share some tips here?
