Understanding How a Refrigerator Compressor Works
To grasp the intricacies of your LG fridge compressor, let’s explore its fundamental operations. The compressor is essentially the heart of the refrigeration system, responsible for circulating refrigerant through the evaporator and condenser coils.
The Refrigeration Cycle
The refrigeration cycle involves several steps:
- Compression: The compressor compresses refrigerant gas, increasing its pressure and temperature.
- Condensation: The hot gas moves to the condenser coils, where it releases heat and transforms into a liquid.
- Evaporation: The liquid refrigerant flows through the expansion valve, entering the evaporator coils and absorbing heat from the refrigerator’s interior.
- Return: The low-pressure refrigerant returns to the compressor, restarting the cycle.
This cycle keeps your refrigerator cool, and any disruption in the compressor’s function can lead to inadequate cooling.
