摘要 |
<p>The invention relates to a high-pressure gas drive unit, in which gas (1, 2) can be compressed via a first compressor (9, 10) on the basis of temperature and pressure differences in high-pressure heat exchangers (A, B), wherein the gas (1, 2) is used for driving a turbine and for heating and cooling. Gas (1, 2) and liquid (3, 4) are partially present in the high-pressure heat exchangers (A, B), wherein the compressed gas (1) acts on the liquid (3), which drives the piston (8) of a further compressor (7). When the two high-pressure heat exchangers (A, B) are at equal pressure, the level of the liquid (4) that has risen in the second high-pressure heat exchanger (B) and the level of the liquid (3) in the first high-pressure heat exchanger (A) are balanced by opening a valve (13) in a connecting line between the two high-pressure heat exchangers (A, B).</p> |
