Residential Under-the-Counter Ice Cube Makers
There are three operating systems in the self-contained ice cube maker:
• The refrigeration system The refrigeration sealed system in the Type 1- self-contained ice cube maker operates similar to a refrigerator/freezer sealed system. The older models used R-12 and the newer models use R-134a. The ice cube maker has a hot gas solenoid valve to harvest the ice; it allows the high pressure refrigerant gas to bypass the condenser and flow through the condenser accumulator tube (Figure 28-3). When the refrigerant enters the condenser accumulator, the hot gas enters into the evaporator plate and it will evenly heat the evaporator plate so that the ice slab will release from the evaporator plate ...
