Understanding Refrigeration
How Does a Fridge Work?
A refrigerator works by removing heat from the interior and expelling it outside. The basic principle involves a refrigeration cycle that includes evaporation, compression, condensation, and expansion. Here's a simplified breakdown:
- Evaporation: The refrigerant, a fluid with a low boiling point, absorbs heat from inside the fridge and evaporates.
- Compression: The gas is compressed by the compressor, increasing its pressure and temperature.
- Condensation: The high-pressure gas releases its heat to the surroundings as it flows through condenser coils at the back of the fridge, turning back into a liquid.
- Expansion: The refrigerant passes through an expansion valve, where it cools down and returns to the evaporator to repeat the cycle.
| Component | Function |
|---|---|
| Evaporator Coil | Absorbs heat from the fridge interior |
| Compressor | Compresses refrigerant gas |
| Condenser Coil | Releases heat to the outside |
| Expansion Valve | Cools down the refrigerant |
