* Reduced system efficiency: Non-condensable gases can reduce the efficiency of the refrigeration system by acting as an insulation layer between the refrigerant and the heat exchanger surfaces. This can lead to increased energy consumption and reduced cooling capacity.
* System damage: Non-condensable gases can also cause damage to the refrigeration system components, such as the compressor and evaporator. This damage can lead to costly repairs or even system failure.
* Contamination of the refrigerant: Non-condensable gases can contaminate the refrigerant, which can lead to a number of problems, including reduced system efficiency, system damage, and health risks.
Purging the line to the refrigerant cylinder helps to ensure that these problems are avoided. To purge the line, a vacuum pump is used to evacuate the line and then a small amount of refrigerant is released into the line. This process is repeated until the line is free of non-condensable gases.
