When an evaporator is not equipped with an equalizer line, what component would you most likely find?

When an evaporator does not have an equalizer line, it is typically necessary to properly distribute the refrigerant throughout the evaporator coil to ensure efficient heat exchange. In this scenario, the presence of a distributor becomes very important.

A distributor is used to ensure that the refrigerant is evenly distributed across the evaporator coil. This is particularly crucial in systems where the refrigerant flow needs to be uniform to prevent issues such as pooling or uneven cooling, which can lead to compressor inefficiencies and system failures. Without an equalizer line to help balance the pressure between the evaporator and the suction line, the distributor compensates by directing the refrigerant evenly, promoting better performance and system stability.

In contrast, the other options do not play the same role in the context of an evaporator without an equalizer line. A suction line is necessary to carry the vapor back to the compressor, but it doesn't address the distribution issue directly. A receiver is not typically associated with evaporators, as it serves a different function in liquid storage before the expansion device. A pressure relief valve is a safety component but does not contribute to the distribution of refrigerant within an evaporator.
