Screw air compressors use two meshing helical screws, while piston air compressors use pistons driven by a crankshaft. What are some of the pros and cons of each type of compressor? Reciprocating designs (hermetic or semi-hermetic) contain many components. This is often referred to as oil “carry-over”. A Reciprocating Compressor uses piston cylinder to compress the refrigerant gas. But many times the cost deters most buyers from purchasing. And a reciprocating compressor would be more efficient than a scroll compressor, which would provide much more power than you would need for your home's size. When matching the compressor to maximize efficiency in a given heat pump system (the same heat exchangers, air and water flow and control valves) a scroll will have a lower heat output compared to a piston compressor picked for the same system - about 4% more on the 3.25HP models and about 12% more on the 5HP models. The scroll compressor is used mostly on air cooled chillers but you can … … Applications include oil refineries, gas pipelines, chemical plants, natural gas processing plants and refrigeration plants.
