Inspection of External Control Valve Compressor (GDS)

Compressor Type: Fixed displacement compressor, externally controlled valve, internally controlled valve. For fixed displacement and internally controlled valve types, compressor operation can be checked by the clutch noise. However, for the externally controlled valve, it cannot be checked this way because it has no clutch. Therefore, the ECV should be checked using GDS as shown below.
