In terms of functionality, which type of compressor tends to have a more continuous operation?

The centrifugal compressor is known for its ability to operate continuously and efficiently at high capacity. It utilizes a rotating impeller to impart velocity to the refrigerant, which is then converted into pressure, allowing for a more constant flow of refrigerant. This design enables centrifugal compressors to handle larger volumes of refrigerant with less fluctuation in output compared to other types of compressors, making them ideal for applications requiring consistent cooling or heating loads, such as in commercial and industrial settings.

In contrast, reciprocating compressors tend to operate in cycles, compressing small charges of refrigerant before drawing in a new charge, which can lead to more variation in their output and less continuous operation. Scroll compressors, while efficient and offering smoother operation than reciprocating types, are often designed for smaller loads and less continuous duty cycles. Hermetic compressors, which are sealed units that contain all components in one shell, can also vary in their operation based on the application but do not inherently provide the same level of continuous duty as centrifugal compressors do.
