Scroll compressors are a type of positive displacement compressor that use two interleaved spiral-shaped scrolls to compress gas. One scroll is fixed, while the other orbits around it, creating pockets that trap and compress the gas as it moves toward the center. This design allows for efficient and quiet operation, making scroll compressors popular in air conditioning and refrigeration systems. These compressors are known for their reliability and low maintenance needs. They can handle a variety of refrigerants, including R-410A and R-134A, and are often used in both residential and commercial applications. Their compact size also makes them suitable for space-constrained environments.
