The main causes of excessive heating of a compressor can be the following: a very high compression ratio (low suction pressure and high discharge pressure), a low refrigerant charge, an operation below the permitted capacity reduction limits.

Lowering the oil level in the cup of a compressor causes a lack of lubrication and of cooling, which results in an abnormal increase in operating temperature, in the seizure of bearings and in the connecting rod block

The migration of the refrigerant into a non-functioning refrigeration system is one of the main causes of oil dilution.

The most common problems regarding lubrication are: oil dilution, lowering of oil level and loss of viscosity due to excessive heating of the compressor. Oil dilution is certainly the most common problem in refrigeration systems.

Let us first examine the mechanical failures caused by liquid shots. Disassembling a compressor, for example, showed that the intake valve was damaged following an attempt to compress coolant or oil, or both.

In a refrigeration system the compressor is rarely the direct cause of mechanical accidents. When a damage of a certain amount occurs in a system equipped with reciprocating compressors, it is therefore important to know the operating conditions thor
