Abstract
An HVAC system includes a compressor with an inlet port, an outlet port, and a scroll set. The scroll set includes a fixed scroll member and an orbiting scroll member. The fixed scroll member includes a first scroll wrap extending vertically from a base of the fixed scroll wrap. The first scroll wrap has an approximately spiral shape with at least 3.5 rotations from the center to the end of the spiral. The orbiting scroll member includes a second scroll wrap extending vertically from a base of the orbiting scroll wrap. The second scroll wrap has an approximately spiral shape with at least 3.5 rotations from the center to the end of the spiral. The orbiting scroll moves in an elliptical pattern such that fluid entering the inlet port of the compressor is compressed from a first volume to a second volume via movement of the orbiting scroll member.
