What does the displayed symbol represent?

The symbol represents a rotary compressor, which is used primarily in refrigeration and air conditioning systems. A rotary compressor operates by compressing refrigerant gas using a rotating mechanism, making it efficient for cooling processes. This type of compressor is commonly characterized by its circular shape in schematics, distinguishing it from other components.

The design elements of the symbol, such as the rotation indication and internal construction depicted, specifically align with the functionality and structure of rotary compressors. It is important to recognize the visual aspects unique to this type of compressor, such as how it compresses gas continuously in a circular motion, which is essential for its operation in cooling applications.

In contrast, the other options represent different components that have distinct symbols and functions. A pressure gauge would typically show levels of pressure, a heating element would be associated with electrical components or coils indicating heat generation, and a capacitor would have a different iconic representation linked to its role in electrical storage and release. Knowing these different symbols and their corresponding meanings is critical in understanding schematics accurately.
