calcium Chloride with NH3 absorption
hey guys...
i am designing an absorption air conditioning and ice maker system... i got some questions....
1. what's the best steel material to use as a generator?
stainless steel? non-galvanized steel? aluminum?
my concern in the material will be a better non-corrosive and a high thermal conductivity. im planning to used the aluminum but i dont know if it could withstand the pressure (up to 2000psi) and if it reacts with the liquid ammonia.
2. for my evaporator:
whats the best material for a my evaporator/ collector? ill be using brine water supplement on my NH3 collector, so it should be a high corrosive resistance.
i am considering a stainless steel over a non-galvanized steel, it is quite expensive but do you think that it will compensate on the length of used
thanks for the help
