Description
English: After the ammonia has been condensed to a liquid state. It passes into a great cylinder called an evaporator. Here it begins to expand again back to a gas and passes into parallel pipes like those you have just seen. But these pipes run through a tank filled with brine. When the ammonia is condensed to a liquid form it gives up all its heat, just as water does when it turns to ice. Then, when it is allowed to expand in passing through the pipes in the brine tank, it absorbs the heat from the brine and makes it freezing cold In this brine tank are set the cans of distilled water to be frozen. This illustration shows the cans being lowered into the brine.
