Understanding How Refrigerators Work
Before you can successfully cool your refrigerator, it’s essential to understand the basic principles of how it operates. Refrigerators use a refrigeration cycle to remove heat from the interior and release it externally. Here’s a simplified breakdown of the process:
The Refrigeration Cycle
- Evaporation: The refrigerant absorbs heat from the inside of the fridge as it evaporates in the evaporator coils.
- Compression: The gas is then compressed by the compressor, raising its temperature and pressure.
- Condensation: The hot gas flows to the condenser coils, where it releases heat and condenses back into a liquid.
- Expansion: The refrigerant expands and cools as it returns to the evaporator coils, allowing the cycle to repeat.
Understanding this cycle will help you diagnose potential issues and implement solutions effectively.
