Abstract
The linear compressor is a piston-type compressor in which the piston is driven directly by a linear motor. The free piston linear compressor has the potential to reduce friction losses and achieve better efficiency. It also promises life and cost benefits. The authors developed our original 2 piston-type linear compressor for refrigerators. This linear compressor operates at 60Hz, uses R134a as refrigerant, and has a cooling capability of 230kcal/h. The results of performance tests show EER of over 1.40. In this paper, we introduce the specifications and the performance test results of our 2 piston-type linear compressor.
