DescriptionNSRW Artificial Ice - compressor pipes.jpg |
English: Most artificial ice is made by what is called the compressor system. It is called the compressor system because the ammonia with which the freezing is done is first compressed by means of powerful steam pumps. These pumps then force it through pipes over which cold water is running. This cold water bath still further condenses the gas to a liquid state, which drives out all the heat there is in it. The illustration shows how water is kept playing on the pipes containing the compressed ammonia. |
