摘要(Abstract):

为开拓间歇式能源应用新途径,本文提出了一种复合制冷系统,该系统带有抽水压缩气体储能装置。在储能阶段,该储能制冷系统通过水泵将电能转换为水气共容舱内带压气体的内能;释能阶段,在水气共容舱内高压气体的作用下,使其内部的水流经水轮机直接驱动制冷循环制冷,而制冷循环中冷凝器所释放的能量被水气共容舱内的高压气体全部吸收,最终完成了利用间歇式能源制冷之目的。文中建立了描述储能与制冷过程的热力学模型,并重点研究了储能和制冷过程中关键节点的热力学参数变化规律,与文献给出的储能制冷系统相比,该系统具有较高的制冷系数。为拓展间歇式能源实际应用途径提供了一种新思路。
To explore the new way of intermittent energy applications,a composite refrigeration system was proposed,which equips with pumping compressed air energy storage device. During the stage of energy storage,the refrigeration system converted electric energy into internal energy of gas-pressurized through the water pump in the cabin; At the energy release stage,the internal water flow through turbine that will drive directly the cycle of refrigeration under the cabin's gas-pressurized,and the heat of the condenser in refrigeration cycle is absorbed by high pressure gas inside the cabin,eventually completed the purposes of using intermittent energy refrigeration. This paper established the thermodynamic model to describe the energy storage and refrigeration process,and focuses on the change of the key node thermodynamic parameters during storage and cooling process. Contrasting with the literature energy storage refrigeration system,this system has higher refrigeration coefficient. And it provides a new way for the development of intermittent energy application.
