What is a major consequence of running a refrigeration system low on refrigerant?

Running a refrigeration system low on refrigerant leads to compressor overheating because the refrigerant plays a critical role in the cooling cycle. When refrigerant levels are low, the compressor is unable to effectively cycle the refrigerant necessary for heat exchange. This reduced flow means that the compressor has to work harder to maintain the cooling function, which can lead to an increase in operating temperature.

This overheating can cause significant damage to the compressor, ultimately leading to premature failure. When the compressor operates without sufficient refrigerant, it may run continuously without cooling adequately, further amplifying the risk of overheating. Maintaining the correct level of refrigerant is essential not only for the efficiency and effectiveness of the refrigeration cycle but also for the longevity of the compressor and the entire refrigeration system.
