Icyball Is Practical Refrigerator for Farm or Camp Use (Aug, 1930)

There is actually a website devoted to the IcyBall units and how to build them

Icyball Is Practical Refrigerator for Farm or Camp Use

MAKING ice from heat at a cost of but two cents a day is one of the latest contributions of science for man’s comfort, convenience and health. The Icyball refrigerator, which operates on this principle, does not require gas or electricity and can be used anywhere.

The operation of this new and unusual refrigerator is simple. There is nothing to get out of order, no moving parts and no odor. It is absolutely noiseless and requires no oiling. The refrigerant never needs replenishing.

The freezing unit consists of two metal balls joined together by a strong metal tube. These balls contain a harmless liquid refrigerant hermetically sealed inside.

Once every 24 hours it is necessary to lift the “Icyball” out of the cabinet, submerging the cold ball in a tub of water, allowing the hot ball to hang outside. The reservoir of the heating unit is filled with kerosene, the flame is lit and the heat soon forces the refrigerant into the cold ball. The “Icyball” is then placed back into the cabinet, and no further attention is necessary for 24 hours. The Icyball is ideal for use in rural homes where it is difficult to obtain ice.

    These actually work and work well. The basic solution is an ammonia and water mix, which gets the ammonia boiled out of it by the heating process. This then condenses on the other side, and because of the water’s affinity for ammonia will evaporate and migrate back into solution on the water side, chilling the ammonia reservoir side.

    The ribald commentary about icy balls I will studiously ignore, of course.

    Very didactic. In this device we can see the absortion refrigerator at work without the complicated ongoing cycle of heating and condensation: just two balloons, one piece of piping and one process.

    Seems like ta good place to repeat my favorite warning from Brainiac “do not try this at home, repeat do not try this at home” Death and destruction can result from mistakes, ammonia is a poison and you are working with pressures high enough to cause a small explosion resulting in sharp ragged chunks of metal flying in all directions.

    Greetings.
    Please he/she would want to have the information to build this refrigeration device, like they can be plane and pictures.
    Also if it was possible they could tell me how the ammonia is loaded in the system.
    thank you
