The following diagram shows the main concepts of the ice cube
makers working (‘sprayers’ system).
Condenser
Air
Water
Evaporator
Each ice maker uses the properties of compression and
expansion of the liquefiable gases; its main principle is that each
change of bodies state is got by producing or absorbing heat.
The compressor sucks up the gases, generated by the
evaporation, and compresses them, increasing their
temperature and pressure.
A condenser, made up of a series of tubes (refrigerated by
cold water or ventilated air), carries away the heat, comprised in
the gas from the compressor and helps, in this way, the gas
liquefaction.
The refrigerating fluid, now in liquid state, circulates, then, in an
evaporator that permits an optimal heat exchange with the out-
room, by taking away calories and producing ice, which is got by
means of the freezing of the water sprayed in the cubes forms
by the spray-bar.
The working of this machine is cyclical: ice cubes are produced
during the first phase and fall in the built-in bin during the
second phase.
