Technological Differences Between Conventional and Inverter Compressors

The video explains the technological differences between conventional compressors and inverter compressors, focusing on their physical characteristics, electrical properties, and operational requirements.

Physical Differences

• Conventional compressors are generally taller.
• Inverter compressors are shorter and smaller.

Electrical Characteristics

• Conventional compressors operate at a fixed frequency (50-60 Hz).
• Inverter compressors operate with a variable frequency and use a three-phase signal.
• Resistance measurements differ between the two types:
  • Inverter compressors show equal resistance across all terminals if coils are intact.
  • Conventional compressors have specific resistance patterns between common, start, and operating terminals.

Operational Components

• Conventional compressors require a start-up circuit and a thermal protector.
• Inverter compressors need an electronic control board, typically an Intelligent Power Module (IPM), which adjusts motor speed by varying voltage and frequency.

Fault Analysis and Repair

• A third compressor failed due to improper suction line input; replacement is suggested over repair.
• Another inverter compressor is mechanically stopped despite correct terminal readings.
• The presenter plans to attempt repairing the inverter compressor and demonstrate how it might operate without its electronic board after repair.

The video serves as both a technical guide and a repair tutorial, highlighting practical diagnostic methods and the complexity of inverter compressors compared to conventional ones.
