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) [S850/S1000 Air & Water Machines

Only - 140°F (60°C)] at the end of the freeze cycle.

PROCEDURE

Connect a temperature probe on the compressor

discharge line with-in 6" of the compressor and

insulate.

Observe the discharge line temperature for the last

three minutes of the freeze cycle and record on the

table.

Discharge Line Temperature Above 150°F (66°C)

[S850/S1000 Air & Water Machines Only - 140°F

(60°C)] At End Of Freeze Cycle:

Ice machines that are operating normally will have

consistent minimum discharge line temperature of

150°F (66°C) [S850/S1000 Air & Water Machines Only

- 140°F (60°C)].
