4.1.7.1 Diagnosis of Compressor Failures
4.1.7.1.1 When the unit can be started
Step 1:
If the unit can be started, check the faulty compressor's line current. Use a pressure gauge to
measure the gas and liquid valve pressure and monitor the measured data on a PC. Compare the data
to the following table of recommended current. The current may deviates by about 10% depending on
the inverter compressor's speed and working condition.
(1) Inverter compressor AA55PHDG-D1Y2:
When the compressor frequency is 30 Hz, the current curve under different evaporation
temperature and condensation temperature is shown as follows:
