摘 要:介绍了蓄冷蓄热复叠耦合系统的组成、工作原理。以珠海某区域能源站为例,对蓄冷蓄热复叠耦合系统与常用的电锅炉谷电系统进行了技术经济对比。结果表明,蓄冷蓄热复叠耦合系统能充分回收区域能源站内夜间用电低谷时制冰产生的低品位废热,高效复叠提升品位后用作城市集中供热的热源,可以进一步调峰填谷、平抑电力需求、降低区域供冷供热成本。The composition and working principle of the cold storage and heat storage cascade coupling system are presented.Taking a regional energy station in Zhuhai as an example,the technical and economic comparison between the cold storage and heat storage cascade coupling system and the commonly used electric boiler valley power system is carried out.The results show that the cold storage and heat storage cascade coupling system can fully recover the low-grade waste heat generated by ice production during the low power consumption valley at night in the regional energy station,and be used as a heat source for urban central heating after efficient cascading and upgrading the grade,which can further adjust peaks and fill valleys,stabilize power demand,and reduce district cooling and heating costs.
