Question: 1 / 400

If a low temperature ammonia booster compressor has a discharge temperature that drops from 120 F to 80 F, what could be indicated?

The compressor is operating normally

There is possibly liquid in the suction line

When the discharge temperature of a low temperature ammonia booster compressor decreases significantly, such as from 120°F to 80°F, it can point to potential issues in the system. One key concern with this scenario is the possibility of liquid refrigerant entering the suction line.

In refrigeration systems, compressors are designed to handle vapor, not liquid. If there is liquid refrigerant in the suction line, it can lead to what is known as "liquid slugging," which can be harmful to the compressor. When a liquid enters the compressor, it does not compress like vapor and can cause mechanical damage due to the pressure build-up and potential flooding.

The drop in discharge temperature might suggest that the compressor is struggling to function properly due to the presence of liquid instead of efficiently compressing vapor. Thus, monitoring for liquid refrigerant in the suction line becomes crucial to ensure the compressor operates effectively and to prevent damage.
