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.
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.
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.
