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.

PROCEDURE

1. Navigate to Service / Real Time Data / Time &

Temp / T2 Thermistor (See

page 81 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.
