Which type of compressor uses rollers to compress refrigerant?

• A. Reciprocating
• B. Screw
• C. Hermetic
• D. Rotary

Answer: (B)

The type of compressor that uses rollers to compress refrigerant is the screw compressor. This type of compressor utilizes two helical rotors that rotate in opposite directions, drawing in and compressing the refrigerant as it moves through the compressor's housing. The rollers within the screw design create a positive displacement effect, compressing the refrigerant efficiently and continuously. Screw compressors are known for their durability, high-efficiency performance, and ability to handle large volumes of refrigerant, making them a preferred choice in many industrial and commercial refrigeration applications. They are particularly effective during varying load conditions and can operate over a wider range of pressures compared to other types of compressors. In contrast, other types of compressors like reciprocating and rotary utilize different mechanisms for compression, such as pistons or rotating vanes, which do not involve the roller mechanism found in screw compressors. Hermetic compressors are sealed units that can be either rotary or reciprocating but do not specifically embody roller-based compression.
