Humidity is one of the main contaminants that are generally found in a refrigeration circuit.

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.

Excessive heating of the compressor leads to a decrease in the viscosity of the oil and one

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
