Stirling motor with three heat sources at different temperatures - has cylinder divided into high, medium and low temperature chambers, and has variable gas displacement volumes in high and medium temp. parts

摘要

The motor has a cylinder (1,2), enclosing a working gas. A high temperature-sided and a low temperature-sided compressor (3,6) divides the cylinder into high/medium and low temp. chambers (4,5,8,7), a first gas channel (9) connecting the high and medium temp. chambers. The channel contains high temp.-sided heat exchanger (10) and regenerator (11), and medium temp.-sided heat exchanger (12). A second gas channel (13) connects low and medium chambers. This has a heat exchanger (14) and regenerator (15) on the low temp. side, and a heat exchanger (16) on the other side. The gas displacement volume in the medium temp. chamber is larger than that in the high temp. chamber. ADVANTAGE - Improved cooling and heating performance.
