What is the main function of the compressor in a refrigeration cycle?

The main function of the compressor in a refrigeration cycle is to compress refrigerant vapor. This process is essential for maintaining the efficiency of the refrigeration system. When the compressor takes in low-pressure refrigerant gas, it compresses it into a high-pressure gas. This increase in pressure raises the temperature of the refrigerant, allowing it to release heat effectively when it reaches the condenser.

In the broader context of how refrigeration systems operate, once the refrigerant is compressed, it moves to the condenser, where it releases the absorbed heat to the environment. It then continues through the cycle by becoming a liquid again and absorbing heat in the evaporator. This cyclical process is what allows the refrigeration system to function effectively in cooling applications. Understanding the compressor's role clarifies its importance in regulating refrigerant pressure and ensuring the overall heat exchange process is efficient.
