DISCHARGE LINE TEMPERATURE ANALYSIS
GENERAL
Knowing if the discharge line temperature is increasing,
decreasing or remaining constant can be an important
diagnostic tool. Maximum 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 150°F (66°C)
on a normally operating ice machine.
PROCEDURE
Connect a temperature probe on the compressor discharge
line within 6” (15.2 cm) of the compressor. Observe the
discharge line temperature for the last three minutes of
the freeze cycle and record the maximum discharge line
temperature.
