存取共用型压缩空气储能蓄热系统
摘要：
本发明提供一种存取共用型压缩空气储能蓄热系统，该存取共用型压缩空气储能蓄热系统包括：蓄热装置，蓄热装置包括多个蓄热器，蓄热器具有用于填充蓄热介质的蓄热腔和与蓄热腔隔离的换热腔，多个蓄热器的换热腔并联连接于蓄热装置的换热流路，且多个换热腔中的至少部分可选择性地与换热流路连通；压缩机，压缩机与换热流路相连；储气装置，储气装置的进口和出口分别连接于换热流路的两端；膨胀机，膨胀机与换热流路相连。本发明的存取共用型压缩空气储能蓄热系统，可以大幅降低投资成本，节省运行电损耗以及空气加热和冷却时的压降损失，提高系统效率，通过设计可独立并入换热流路的多个蓄热器，确保存储的热能为高温度的高品质热能。
摘要（英）：

The invention provides an access shared compressed air energy storage and heat storage system. The access shared compressed air energy storage and heat storage system comprises a heat storage device,a compressor, an air storage device and an expander, wherein the heat storage device comprises a plurality of heat accumulators; each heat accumulator is provided with a heat storage cavity used for being filled with a heat storage medium and a heat exchange cavity isolated from the heat storage cavity; the heat exchange cavities of the heat accumulators are connected to a heat exchange flow pathof the heat storage device in parallel; at least part of the heat exchange cavities selectively communicate with the heat exchange flow path; the compressor is connected with the heat exchange flow path; an inlet and an outlet of the air storage device are connected to the two ends of the heat exchange flow path correspondingly; and the expander is connected with the heat exchange flow path. According to the access shared compressed air energy storage and heat storage system, the investment cost can be greatly reduced, the operation electric loss and the pressure drop loss during air heating and cooling are reduced, the system efficiency is improved, and the stored heat energy is ensured to be high-temperature and high-quality heat energy by designing the multiple heat accumulators capableof being independently merged into the heat exchange flow path.
