The Differences between a Scroll Compressor and a Rotary Compressor

The Differences between a Scroll Compressor and a Rotary Compressor

When shopping for an air conditioning system, the type of compressor technology it usesā€”specifically, whether it has a scroll or rotary compressorā€”can significantly influence efficiency, performance, and durability. Understanding the differences between these two can help you make an informed decision, ensuring you choose the best cooling solution for your needs.

Scroll Compressor


The scroll compressor is known for its efficiency and durability, making it a popular choice in residential and commercial comfort systems. This type of compressor operates with two spiral-shaped scrolls; one remains stationary while the other orbits around it, compressing the refrigerant by pushing it into increasingly smaller areas. The design of scroll compressors allows for fewer moving parts, which not only reduces mechanical wear but also decreases the noise levels during operation. Additionally, scroll compressors are known for their ability to handle higher pressures and efficiency which translates to energy savings and consistent comfort in temperature management.

Rotary Compressor


On the other hand, rotary compressors are typically found in smaller air conditioning units, suitable for both residential and light commercial applications. These compressors feature cylindrical rotors and utilize a simple and compact design, making them cost-effective and relatively easy to manufacture. Rotary compressors operate by having a rotor turn in a circular motion within a cavity, compressing the air or refrigerant by reduction in volume. While they are generally less efficient than scroll compressors, they excel in low-duty applications and are valued for their small size and lower initial investment.

Both scroll and rotary compressors offer unique benefits. Your choice will depend on your specific needsā€”whether thatā€™s prioritizing durability and efficiency with a scroll compressor or opting for the cost-effectiveness and compact size of a rotary compressor. Understanding these differences empowers you to optimize your air conditioning system for the best performance and efficiency.
