谷电相变储热技术的设计与应用

Design and application of phase-change heat storage technology during valley electricity

介绍了谷电储热技术的基本原理及分类,并分析了该技术在当前能源市场推广的适宜性。结合上海某医院案例,对比分析了分别采用谷电相变储热和传统燃气锅炉2种热源供空调热水+生活热水、只供生活热水的设备配置、机房面积及经济性。结果表明,谷电相变储热技术在上海适用于生活热水储热,不宜对空调热水+生活热水进行储热。

This paper presents the basic principle and classification of valley electric heat storage technology,and analyses the suitability of the technology in the current energy market.Taking a hospital in Shanghai as an example,equipment configuration,equipment room and the economy for these different cases are listed and compared in the plans of phase-change heat storage during valley electricity and gas boiler for heat load of domestic hot water and air conditioning and only for heat load of domestic hot water.The results show that the phase-change heat storage technology is suitable for the heat load of domestic hot water in Shanghai,but not suitable for the heat load of air conditioning and domestic hot water.
