What is the name of the pipe that connects the evaporator back to the LPR in a recirculated system?

In a recirculated cooling system, the pipe that connects the evaporator back to the low-pressure receiver (LPR) is known as the wet suction line. This line is essential for transporting the vaporized refrigerant from the evaporator to the compressor.

The wet suction line carries the refrigerant in its gaseous state, which has absorbed heat from the space being cooled. This exemplifies the cycle of refrigeration where the low pressure at the evaporator allows the refrigerant to boil and absorb heat effectively before it is drawn back into the compressor.

Understanding this function is crucial for maintaining the efficiency and effectiveness of the cooling system, as any issues in the wet suction line can directly impact the system's performance. Other options represent different components or processes in refrigeration systems, but they do not accurately describe the specific connection from the evaporator back to the LPR like the wet suction line does.
