In a system with an evaporator and a throttling device, what component is located directly after the evaporator on the low-pressure side?

The suction accumulator is located directly after the evaporator on the low-pressure side. Its job is to trap any liquid refrigerant that may be carried over from the evaporator and hold it so only vapor continues to the compressor. This prevents liquid slugging, which can damage the compressor. In a typical path, refrigerant goes evaporator → suction line → accumulator → compressor. The other components sit on the high-pressure side or in the liquid line before the throttling device, so they aren’t located directly after the evaporator on the low-pressure side.
