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 150°F (66°C) at the end of the freeze cycle.
