What type of compressor is effective for high-pressure applications?

• A. Screw compressor
• B. Vane compressor
• C. Reciprocating compressor
• D. Centrifugal compressor

Answer: (A)

A screw compressor is particularly effective for high-pressure applications due to its design and operational characteristics. It functions using two intermeshing rotors, which compress the refrigerant continuously as it moves through the unit. This design allows for a smooth flow of refrigerant and the ability to maintain high pressure efficiently, making it suitable for applications that require consistent and high-pressure outputs. Moreover, screw compressors tend to have a higher volumetric efficiency compared to other compressors, which means they can handle larger volumes of gases at higher pressures without a significant loss of performance. This capability makes them a popular choice in industrial and commercial refrigeration systems where high capacities are needed. Other types of compressors like reciprocating or vane compressors may also be used in high-pressure applications, but they typically have limitations in capacity and efficiency when compared to a screw compressor. Centrifugal compressors, while efficient for certain applications, are primarily effective at low pressure and high flow rates and may not provide the required pressure for high-pressure applications as effectively as screw compressors do.
