The liquid line in a refrigeration system connects which two components?

In a refrigeration system, the liquid line serves a crucial role in transporting the refrigerant in its liquid state. The correct connection for the liquid line is between the receiver and the metering device.

The receiver's function is to store liquid refrigerant coming from the condenser, ensuring that there is a steady supply for the system. The metering device, which can be a thermal expansion valve or capillary tube, regulates the flow of refrigerant into the evaporator while maintaining the appropriate pressure and temperature. This allows for proper heat exchange as the liquid refrigerant absorbs heat and evaporates in the evaporator, completing the refrigeration cycle.

This connection is vital for maintaining the efficiency and effectiveness of the refrigeration cycle, ensuring that the system operates reliably and effectively. The other options refer to different components and fluid paths in the refrigeration cycle, but they do not accurately describe where the liquid line connects, which is why they do not represent the primary function of the liquid line.
