Understanding the Basics of Refrigerator Compressors
To appreciate how hot a refrigerator compressor should get, it’s essential to understand its role within the refrigeration cycle. The compressor is the heart of the refrigerator’s cooling system. It compresses the refrigerant, increasing its pressure and temperature before circulating it through the evaporator coils, where it absorbs heat.
The Refrigeration Cycle Explained
- Compression: The compressor draws in the low-pressure refrigerant gas and compresses it into a high-pressure gas, raising its temperature in the process.
- Condensation: The high-pressure gas then travels through the condenser coils, where it dissipates heat and condenses back into liquid form.
- Evaporation: This liquid refrigerant then flows through the expansion valve, drops in pressure, and evaporates in the evaporator coils, absorbing heat from inside the refrigerator and cooling the air.
- Recycling: The cycle continues as the low-pressure gas returns to the compressor.
Understanding these stages provides clarity on the importance of optimal compressor temperatures.
What Is the Ideal Temperature for a Refrigerator Compressor?
