What factor can lead to compressor overheating in a refrigeration system?

Insufficient refrigerant coupled with poor airflow is indeed a significant factor that can lead to compressor overheating in a refrigeration system. When there is insufficient refrigerant, the system lacks the necessary substance to adequately absorb heat from the interior of the refrigerated space. This results in the compressor working harder to circulate the limited refrigerant present, which increases its temperature.

Furthermore, poor airflow can exacerbate this issue. If the airflow over the evaporator coils is restricted, the heat exchange process becomes inefficient, leading to elevated pressure and temperature within the system. As the compressor continues to operate under these stressed conditions, it can lead to overheating, potentially causing damage or failure. Therefore, ensuring proper refrigerant levels and adequate airflow is crucial for the efficient operation of refrigeration systems and helps maintain the compressor's health.
