Two-stage linear compressor with economizer cycle where piston(s) stroke(s) are varied to optimize energy efficiency.

Author(s) : SHAPIRO D., ROHRER C.

Summary

The energy efficiency of a dual piston linear compressor with two-stage compression and an economizer cycle can be improved by controlling the relative displacement of the pistons. Existing scroll and screw compressors can take advantage of the economizer cycle which increases cooling capacity and improves energy efficiency. A dual piston linear compressor with two-stage compression can take advantage of an economizer cycle in a similar way. The efficiency gain with an economizer cycle depends on many factors, but in particular on the intermediate pressure. By varying the relative displacements of the two pistons, the energy efficiency of the compressor can be maximized for given evaporating and condensing temperatures.
