摘要
给出了一种采用相变材料(PCM)实现蓄冷和蓄热双重功能的户式蓄能型热泵冷热水机组,用以解决夏季电力移峰填谷和空气源热泵冬季昼夜供热不平衡的问题。介绍了机组的原理和设计方法,以及具有多种功能的三套管蓄能换热装置结构。针对上海的一具体建筑,设计了满足其空调要求的机组,并采用焓法模型,对机组的各种蓄能释能过程进行了模拟研究,分析了蓄能释能的特点。
The article presents a new system that uses phase change material（PCM） for household central energy storage haat pump water chiller/heater units with double functions of cold and heat storage. The system can achieve peak load shifting in summer and solve the imbalance of heat supply between day and night in winter. It also presents the fundamentals and design procedure Of the system, and a tri-casing energy storage and heat exchange equipment with many kinds of functions, A new energy storage equipment is presented and a sample unit for a building in shanghai is designed. It uses the enthalpic method model to simulate the process of energy storage and discharge and analyzes its characteristics.
