摘要：
本发明提供一种基于高压液体的冷热电联供的电能替代系统和方法，所述系统包括制备液态空气的子系统、利用所述液态空气的发电子系统、利用其中的热能的制冷子系统和制热子系统；所述制备液态空气的子系统包括空气压缩机、空气循环压缩机和液态空气储存器，所述空气压缩机和所述循环空气压缩机分别设有级间换热器。本发明仅通过两次压缩就达到所要求的高压，节省了深冷泵加压的过程，也就节省深冷泵加压过程所消耗的能量，设备加工和维修费用；本发明提供的技术方案空气压缩、存储和膨胀过程中的降温、加热过程使用的换热介质实现了能量的循环利用，方便快捷，节省了能量和人力；实现了冷热电联供，大大避免了能量和资源的浪费。
摘要（英）：

The invention provides an electric energy replacement system and method of combined supply of cooling heating and power based on high pressure liquid. The electric energy replacement system comprisesa subsystem for preparing liquid air, a power generation subsystem utilizing the liquid air, a refrigeration subsystem utilizing the heat energy and a heating subsystem. The subsystem for preparing the liquid air includes air compressors, air circulation compressors and a liquid air storage, and the air compressors and the air circulation compressors are separately provided with interstage heat exchangers. The electric energy replacement system achieves the required high pressure only through two compressions and saves the process of cryogenic pump pressurization, the energy consumed in the process of cryogenic pump pressurization and the equipment machining and maintenance costs; according to the technical scheme, the heat transfer medium used in the cooling and heating processes of air compression, storage and expansion realizes the recycling of energy, convenience and speediness are achieved, and energy and manpower are saved; combined supply of cooling heating and power is realized, and the waste of energy and resources is greatly avoided.
