The process starts with a vessel with water containing dissolved ammonia inside, as known as generator. The burner heats the generator until it reaches the ammonia boiling point. The ammonia leaves the generator and wafts up into the condenser because ammonia boils at a lower temperature than water does. Then, the ammonia starts to cool and forms liquid ammonia in the condenser, without water in it.
Cool It Down
The ammonia flows down from the condenser into the evaporator, a chamber filled with hydrogen with low pressure. In the evaporator, the ammonia expands and cooling rapidly. It is the fan on the evaporator that cools down the air as it blows past. Then, the cold air will circulate through the fridge.
Back to The Beginning
The absorber sends water trickling through the evaporator. While ammonia dissolves easily in water, the hydrogen is otherwise. Then, the water trickles down with the dissolved ammonia in tow and flows back to the generator, starting the cycle from beginning.
