| 摘 要： | 以太阳能应用为背景，讨论了能够实现独立建筑冷热电联供的两种分布式能源系统的原理。以太阳能作为唯一热源，用于加热气体工质，进行闭式Brdyton循环发电。其透平释放的余热通过余热制冷方式供冷或通过换热器直接供热．可实现独立建筑的冷热电联供。当把燃料电池系统和该热动力系统组合起来，则可实现白天和夜间连续的独立建筑冷热电联供。该系统不消耗化石能源，无污染，能源利用效率高，具有进一步理论研究的价值和推广应用潜力。 |

| Abstract: | Based on the application of solar energy, the principle of a distributed energy system for cooling-heating-power cogeneration for a single building was discussed. Solar energy was used as the only heat source to drive a closed Brayton cycle to generate power. The waste heat dissipated by the turbine was utilized by a recovery refrigeration cycle to provide cooling or was directly transferred by heat exchangers for heating. When the system was further combined with a fuel-cell system, the whole system can provide cooling-heating-power continuously in day and night. The system did not consume fossil fuel and dissipate no pollutant with a high energy efficiency. It's worthy further study and introduce to practical application to solve the power crisis in summer. |
