Discharge Line Temperature Analysis
General
Compressor discharge line temperature on a normally
operating ice machine steadily increases throughout
the freeze cycle. Comparing the temperatures over
several cycles will result in a consistent maximum
discharge line temperature.
Ambient air temperatures affect the maximum
discharge line temperature.
Higher ambient air temperatures at the condenser =
higher discharge line temperatures at the compressor.
Lower ambient air temperatures at the condenser =
lower discharge line temperatures at the compressor.
Regardless of ambient temperature, the freeze cycle
discharge line temperature will be higher than 71°C on
a normally operating ice machine.
Procedure
Connect a temperature probe on the compressor
discharge line within 6" of the compressor.
Observe the discharge line temperature for the last ten
minutes of the freeze cycle and record the maximum
discharge line temperature.
