In an orifice-tube system, which list correctly identifies low-pressure side components?

Understanding which parts sit on the low-pressure side helps you track how the refrigerant moves after it has expanded. After the expansion device, the refrigerant enters the evaporator at low pressure, absorbs heat, and then returns as low-pressure gas via the suction line toward the compressor. The evaporator is the primary low-pressure heat exchanger in this path. The accumulator sits in the low-pressure downstream path to hold liquid that could slug the compressor, ensuring only vapor returns to the compressor. The expansion device in an orifice-tube system is the orifice that creates the pressure drop before the evaporator, so the section feeding the evaporator operates at low pressure as a result. Therefore, the components on the low-pressure side are the orifice device, the evaporator, and the accumulator. Condenser and receiver/drier are on the high-pressure side, and while the compressor interacts with both sides, it is associated with the high-pressure portion due to its discharge pressure.
