FREEZE CYCLE
WATER SYSTEM
A combination of a solenoid water inlet valve
with a water level sensor is used to control the
level of the water into the reservoir or sump.
A pump, running continuously, after the first
40" of freezing cycle, forces the water to the
top of the evaporator, where it is distributed
through a water tube and then cascades down
the evaporator surface by gravity. As it flows
across the refrigerated evaporator, some of
the water will be chilled enough to change
form, turn to ice, and stay frozen onto the
evaporator cells. Most of the water returns to
the reservoir, to be sucked back into the
pump, and re-pumped over the evaporator.
