Scroll vs. Reciprocatory Compressor

● Scroll Compressor has a moving scroll which creates pressure.The motion of a scroll compressor is as shown below:

● A Reciprocating Compressor uses piston cylinder to compress the refrigerant gas. The basic diagram of a reciprocating compressor is shown below:

Which one is better?

● Scroll Compressors are More Efficient

● Scroll compressors run quieter and smoother than reciprocating compressors because they only have two moving parts: a fixed and orbital scroll.

● Fewer parts make the scroll compressor energy efficient, highly reliable, and less prone to mechanical failure.

● Low-cost manufacturing of scroll compressors make replacement more cost-efficient than repair.
