| 摘 要： | 对新型蓄冷系统——直接接触式冰蓄冷系统进行了火用分析,并通过与常见的盘管式冰蓄冷系统进行对比,发现直接接触式冰蓄冷系统的火用效率有极大的提高,从而表明直接接触式冰蓄冷系统具有广泛的应用前景. 同时通过对系统各部件火用损失的分析,表明提高系统火用效率的有效措施是系统中采用高效的与制冷剂相匹配的压缩机.

| Abstract: | The application of exergy analysis to the direct contact ice thermal storage system is investigated in order to assess the efficiencies of the system. The system consists of a compressor, a condenser, an expander and a direct contact evaporator. The exergy efficiency and its loss in each component have been evaluated by means of its exergy balance equation. The results show that the direct-contact ice storage system is more preferable than the general ice-on-coil system, and adopting an advanced compressor matched by the refrigerant is an efficient measure to improve the performance of the system. |
