Evaporator Efficiency
The evaporator on the Cornelius/Wilshire icemaker can be tested for efficiency in three easy ways.
1. Simply observe the ice coming out of the extruder head during production. As the auger rotates, an ice chunklet should pop out of each
extruder slot on every rotation.
2. Frost pattern testing of the evaporator. Open up the icemaker so that the auger/extruding head can be removed (this may require waiting
until the evaporator has thawed out). Remove the assembly and allow the evaporator to fill with water. Start up the icemaker and allow it to
run for exactly one minute and forty-five seconds. Immediately shut the unit down, drain the evaporator or use a flashlight to look down into
the cylinder. A sleeve or spiral of ice should have formed inside the evaporator tube. This sleeve should extend the full length between the
refrigerant inlet and suction outlet lines. There should be no interruptions, gaps or holes in this pattern. There will not be any ice at either
end, which are beyond the refrigerant lines.
3. Weighing output. The 24-hour output of the icemaker may be determined by weighing its output of Ice for 15 minutes and multiplying that
figure by 96. This figure can also be used to calculate water usage. The weight of the melted ice (water) must be included in either of the
above calculations for accuracy. The icemaker should be run for at least 5 minutes before starting the test.
Superheat & Suction Temperature
Cornelius/Wilshire Chunklet icemakers run at a ~ 4 degree F superheat, for those reasons they are equipped with non-adjustable expansion
valves.
Suction temperature nominally runs at 8 – 12 degrees below zero, remote systems are apt to run at lower temperatures due to their
environment.
