The Role of the Compressor in the Refrigeration Cycle
Understanding where the compressor is located helps to grasp its importance in the refrigeration cycle:
1. Compression Phase
The compressor receives refrigerant gas from the evaporator at low pressure. It compresses this gas, raising its temperature and pressure before sending it to the condenser coils.
2. Condensation Phase
When the hot, high-pressure gas reaches the condenser, heat is released into the surrounding air, and the gas transforms into a high-pressure liquid.
3. Expansion Phase
This high-pressure liquid then passes through an expansion valve, where it experiences a drop in pressure and temperature, becoming a low-pressure liquid.
4. Evaporation Phase
Finally, the low-pressure liquid absorbs heat as it flows through the evaporator coils inside the refrigerator, turning back into gas, and the cycle begins anew.

What is a refrigerator compressor, and what does it do?
A refrigerator compressor is a crucial component that functions as the heart of the refrigeration system. Its primary role is to compress refrigerant gas, increasing its pressure and temperature. This process allows the refrigerant to flow through the system, absorbing heat from the interior of the refrigerator and releasing it to the outside environment. By doing this, the compressor helps maintain the desired temperature inside the fridge, ensuring your food remains fresh and safe.
In essence, the compressor converts low-pressure refrigerant gas into high-pressure gas, which then moves to the condenser coils. The heat exchange that occurs in these coils allows the refrigerant to cool down and turn back into a liquid state, enabling the refrigeration cycle to continue. Without a functioning compressor, your refrigerator would be unable to cool effectively, leading to spoiled food and inefficient operation.
