Discharge Line Temperature Analysis
GENERAL
Knowing if the discharge line temperature is
increasing, decreasing or remaining constant can be
an important diagnostic tool. Compressor discharge
line temperature on a normally operating ice machine
steadily increases throughout the freeze cycle.
Ambient air temperatures affect the discharge line
temperature.
Higher ambient air temperatures at the condenser
and/or higher inlet water temperature = higher
discharge line temperatures at the compressor.
Lower ambient air temperatures at the condenser and/
or lower supply water temperature= lower discharge
line temperatures at the compressor.
Regardless of ambient and water temperatures, the
freeze cycle discharge line temperature will be higher
than 71°C at the end of the freeze cycle.
PROCEDURE
1. Navigate to Service / Real Time Data / Time &
Temp / T2 Thermistor (See page 59 Service Menu
Navigation for details).
2. Observe the discharge line temperature (T2) for
the last three minutes of the freeze cycle and
record on the table.
Discharge Line Temperature Above 71°C At The
End Of Freeze Cycle:
Ice machines that are operating normally will have
consistent minimum discharge line temperature of
71°C.
