Stirling type thermodynamic device for autonomous heat pump, has chambers arranged on working liquid circuits, and shifter connected to lower parts of chambers so that each chamber is entirely filled with fluid when shifter is put in motion

摘要

The device has two chambers (12a, 12b) arranged on working liquid circuits (13a, 13b) at high and low temperature levels, respectively. A shifter (14c) allows simultaneous variation of volumes of the chambers to a constant cumulated volume, where lower parts (121a, 121b) of the chambers are occupied by the working liquid, and top parts (122a, 122b) of the chambers are occupied by a working gas that moves between the chambers via a duct (11). The shifter is connected to the lower parts of the chambers, so that each chamber is entirely filled with the fluid when the shifter is put in motion. An independent claim is also included for a thermal transfer method.
