How Does A Compressor Keep The Refrigerator Cold?

How does a compressor keep the refrigerator cold?

A compressor plays a crucial role in maintaining the cold temperature inside a refrigerator. It is the heart of the refrigerator’s refrigeration system. The compressor works by drawing refrigerant from the low-pressure side of the system, which is the evaporator coil, and compressing it into a high-pressure gas. This high-pressure gas is then sent through a condenser coil, typically located at the back or bottom of the refrigerator, where it releases its heat to the surrounding air.

As the refrigerant gas flows through the condenser coil, it experiences a significant increase in temperature, causing the surrounding air to absorb the heat. This process cools the refrigerant gas, and it eventually condenses into a liquid. The liquid refrigerant is then routed through an expansion valve, which reduces the pressure and allows the cool liquid to expand into the evaporator coil. Inside the evaporator coil, the refrigerant absorbs heat from the surrounding air, cooling it down as it evaporates into a gas.

The cooled air is then circulated throughout the refrigerator by a fan, helping to maintain a consistent temperature inside. As the refrigerant gas is drawn back into the compressor, the cycle repeats itself, ensuring that the refrigerator remains at a stable cold temperature. This continuous cycle of compression, condensation, expansion, and evaporation is what keeps the refrigerator running efficiently and maintaining the desired temperature.

In summary, the compressor’s function is to compress the refrigerant, allowing it to release its heat and cool down, which ultimately maintains the cold temperature inside the refrigerator. Without a working compressor, the refrigeration system would not be able to function, and the refrigerator would fail to keep food and drinks at the required temperature.
