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

The primary purpose of a liquid line receiver in refrigeration systems is to store liquid refrigerant. This component plays a crucial role in ensuring a steady supply of refrigerant to the expansion valve by acting as a reservoir. It allows for the collection of excess liquid refrigerant, which can help regulate flow and maintain an efficient operation, particularly during fluctuations in cooling demands.

By storing liquid refrigerant, the receiver also helps prevent liquid slugging by providing a buffer against surges in liquid flow, thus enhancing the reliability and efficiency of the refrigeration cycle. This storage function is essential for the system to operate smoothly and maintain consistent performance without overloading the expansion device.
