What is the primary purpose of a liquid receiver in a refrigeration system?

The primary purpose of a liquid receiver in a refrigeration system is to store liquid refrigerant. The liquid receiver serves as a reservoir that holds the refrigerant after it has undergone condensation. By storing liquid refrigerant, the liquid receiver ensures that there is a steady supply available for the refrigeration cycle, allowing for consistent operation of the system.

In addition, the liquid receiver helps to stabilize the pressure within the system, which is essential for efficient refrigeration performance. It provides a buffer to cope with varying loads, ensuring that the evaporators receive the necessary amount of liquid refrigerant for optimal heat exchange. This capacity to store liquid also enables the system to handle momentary fluctuations in pressure and flow during operation.
