The figures below shows cooling capacity curves, and input power curves, and refrigerant flow rate
curves, which are obtained in the testing condition that suction temperature is 35℃, and liquid subcooled
temperature is 8.3℃, and ambient temperature is 35℃.
NOTE: You can infer from the preceding figures the current of the compressors operating at other
frequency bands.
Step 2: Check whether the compressor sounds sharp or rubs. Compare the sound of the faulty
