| TYPES OF CUBELET ICETYPES OF ICE |
| ICE MAKING PROCESS |
| Requires the movement of refrigerant through a network of tubes/coils while a continuous
cycle of condensation
|
and expansion takes place.
|
| Condensation is accomplished by forcing the refrigerant through narrow tubes, while
expansion is achieved by
|
releasing the refrigerant into larger tubes.
|
Refrigerant
|
 |
When compressed, the refrigerant pressure and temperature is increased. As
the hot refrigerant continues its
|
|
cycle through the narrow tubes (coils), it loses
heat to the cooler, outside air.
|
|
This cooling causes the refrigerant to condense into a liquid.
|
|
The compressed liquid is then passed through an expansion valve at which
point it evaporates and becomes
|
|
a gas.
|
|
The evaporation process draws in the heat energy from the copper tubing and
the air surrounding the refrigerant
|
|
thereby cooling the tubing.
|
|
Sandwiched between two stainless steel plate surfaces (evaporator), the cool
temperature from the tubing is
|
|
transferred to the evaporator.
|
|
Freeze Cycle
|
|
Once the evaporator has been cooled, water runs over the evaporator
surface and gradually begins to
|
|
freeze. (water supplied from the reservoir)
|
|
Because pure water freezes first and because water is constantly flowing over the
surface of the evaporator,
|
|
impurities are washed away while pure water is left
behind to freeze. This ice forming process results in the
|
|
formation of a crystal clear
cube.
|
Harvest Cycle
|
|
When the water level in the reservoir reaches a certain level, the ice making
process is terminated.
|
|
A valve is then opened which changes the path of the refrigerant.
|
|
Hot refrigerant gas from the compressor now bypasses the narrow
condensing tubes and is instead routed
|
|
directly to the evaporator.
|
|
The hot temperature from the tubing is transferred to the evaporator, which
loosens the ice cubes,
|
|
leaving them free to fall.
|
|
This freezing and harvesting cycle will continue until the bin control senses that
enough ice has been
|
|
produced.
