What is the abnormal low level percentage for the intercooler liquid?

In industrial refrigeration systems, the intercooler plays a crucial role in improving the efficiency of the system by cooling the refrigerant before it enters the next stage of compression. Maintaining the correct liquid level in the intercooler is essential for optimal operation. An abnormal low liquid level can lead to issues such as decreased efficiency, increased compressor wear, and possible system damage.

A liquid level percentage of 18% in the intercooler is typically considered an abnormal low level. At this percentage, the intercooler may not have enough refrigerant to effectively absorb and remove heat from the compressed refrigerant. This can result in higher discharge temperatures, leading to potential damage to the compressor and other components.

In contrast, levels above 18% are generally seen as more acceptable, indicating that there is sufficient liquid present to ensure proper heat exchange and system functionality. Levels such as 25%, 22%, and even 10% would likewise be above this critical threshold, thus contributing positively to the intercooling process and overall refrigeration efficiency.
