Which compressor type may have safety springs internally for liquid?

The reciprocating compressor is specifically designed to handle varying types of refrigerants and can manage liquid refrigerant in certain operating conditions. This compressor type often incorporates safety springs or valves that allow for the safe expulsion of liquid refrigerant that may enter the compression chamber. These features prevent operational issues that could result from liquid slugging, which can damage the compressor.

The design of the reciprocating compressor allows it to compress gases effectively while also providing mechanisms to handle liquid, making it a suitable choice among the compressor types listed. This capability is essential for maintaining safe operating conditions and ensuring the longevity of the equipment by mitigating risks associated with liquid entering the compression stage.

In contrast, the other compressor types generally have different construction and operational characteristics that are not specifically designed to manage liquid refrigerants with the same level of safety measures.
