hello
i am trying to build a low capacity ammonia refrigerator,which could be used to manufacture ice.is this possible? the idea is to charge an open type compressor(say a gun metal compressor,so that ammonia doesent react with it), use aluminium pipes all round, aluminium evaporator and condenser.waht are going to be the possible areas of failure? why has ammonia refrigeration not been done on a small scale till date(or has it been done?)?
