I want to build a Ammonia Absorbtion Refrigerator. Can it be done using Household Ammonia.?
You need to realize that the ammonia needed for an absorbtion system is a very dangerous material and something someone as inexperienced as you appear to be should leave alone. Pure ammonia has a vapor pressure very similar to propane which means you have to have it at about 200 psi in order to condense it to a liquid. Ammonia also needs specific piping materials and valves. Pure ammonia in contact with your eyes, mucous membranes and lungs can do sufficient damage to leave you severely injured or dead.
