1)bearing failure

2)insufficient refrigent

3)compressor motor consuming more current not working properly

4)expansion valve or capilary block

1 - Missalignment.

2 - Internaly gas leakage

3 - Low performance of interstage cooler.

4 - Bearing faileur

5 - insufficint refrigerant

Due to the leakage of gas, which increases the temperature of the compressor

1. May be compressor on surging

2. Interstage cooler very low performance leeds high temperature of refrigeration gas

3.High pressure.

There could be a couple of reasons:

  • Restricted supply of refrigerant
  • leaky refrigerant plant
  • insufficient refigerant
  • excessive load on the system
  • filters on the suction side clogged
  • suction/discharge valves clogged
