What function does a liquid receiver serve in a refrigeration system?

In a refrigeration system, the liquid receiver plays a crucial role by storing liquid refrigerant. Its primary function is to ensure the refrigeration cycle operates efficiently by providing a reservoir for liquid refrigerant after it has been condensed. The receiver allows for a steady supply of refrigerant to the expansion device or evaporator, which helps maintain system balance and performance.

The liquid receiver also helps accommodate variations in refrigerant flow due to changing load conditions. By holding excess refrigerant, it prevents fluctuations in pressure and ensures that the system can continuously operate effectively without running dry of refrigerant. This storage function is essential for both the reliability and efficiency of the refrigeration system.
