电热高温相变储能装置设计与应用

Design and Application of Electric Heating High Temperature Phase Change Energy Storage Device

伴随全球环境的不断恶化,能源的不断枯竭,如何充分有效地利用能源以及对新能源的开发已经成为业界关注的热点。相变储能技术是利用相变材料在其物理相变化过程中从环境吸热(冷)量或向环境释放热(冷)量,从而达到能量的储存与释放的目的。设计了一款电热高温相变储能装置,将电能转化为热能并通过储存介质储存起来,用于温室内的加温使用。该装置可以平衡电网峰谷差,提高用电效率,减少环境污染,降低用户运行费用,为温室的管理及植物的生长提供必要的条件,对温室产业的发展具有重要的意义。

With continuous deterioration of global environment, continuous depletion of energy, how to make full use of energy and development of new energy has become focus of attention of industry. Phase change energy storage technology use phase change materials in physical phase change process from ambient heat （cold） or release amount of heat （cold） to environment, so as to achieve energy storage and release. A electric heating high temperature phase change energy storage device was de- signed. This device transformed electric energy into heat energy and stored it in storage medium, which was used for heating in greenhouse. Electric heating high temperature phase change energy storage device could balance difference between peak and valley of power grid, improve electricity efficiency, reduce environmental pollution, reduce user operation cost, and provide necessary conditions for management of greenhouse and growth of plants. It had great significance to development of greenhouse industry.
