1. Affecting the lifespan of the compressor: Long-term excessively high exhaust temperature will directly shorten the working life of the compressor. For instance, if the exhaust temperature rises by more than 10℃, the lifespan of the compressor may be halved.
2. Leading to deterioration of lubricating oil: Excessively high exhaust temperature can cause carbonization of the lubricating oil, affecting its viscosity and lubricating performance, thereby accelerating the wear of the compressor.
3. Affecting the stability of the refrigerant: Excessively high exhaust temperatures can cause chemical decomposition of the refrigerant, generating harmful substances and polluting the system.
4. Cause system failure: Excessively high exhaust temperature can lead to expansion of internal components in the unit, causing motor failure. It may even result in the piston getting stuck in the cylinder and the burning out of the built-in motor of the hermetic compressor.
5. Impact on motor performance: For some compressors, exhaust gas has the function of cooling the motor. Excessively high exhaust temperature can cause the temperature of the motor windings to continuously rise, easily triggering the overheat protection system of the unit and even damaging the motor.
6. Impact on sealing performance: When the internal temperature of the compressor reaches the melting point of the sealing material, it will cause permanent damage to the compressor's scroll, drive bearings, internal seals, etc
In conclusion, strictly controlling the exhaust temperature of the compressor is of vital importance for ensuring the reliability of the system, extending the service life of the compressor, and preventing faults.
