本文介绍了一种新型太阳能热动力加热、冷却和热水系统的能量性能研究，该系统集成了潜热储能（LHTES），将该系统应用于美国不同ASHRAE气候区的城市。这项研究是通过计算和比较家庭空间供暖、制冷和热水负荷的能源需求来进行的；每日太阳收获；以及辅助供热。此外，还实施了一种设计方法，以确定LHTES系统和太阳能集热器在不同气候区运行的尺寸。受试城市是从美国七个ASHRAE气候区中随机选择的。能量性能分析表明，太阳能热利用- 与LHTES系统集成的动力加热、冷却和热水系统有助于建筑节能。当太阳能集热器与LHTES系统耦合时，以及仅使用太阳能集热器时，对节能进行了评估。例如，佛罗里达州迈阿密的一个LHTES系统（选自ASHRAE Climate Zone 1）被发现比没有太阳能收集器或LHTES的系统节省了约67.72%的能源，而只有太阳能收集器的系统节省了约38.69%。明尼苏达州德卢斯的一个LHTES系统选自ASHRAE气候区7，被发现可节省约57.96%的住宅建筑能源。当只使用太阳能集热器时，节能率约为29.56%。总的来说，这项研究证明了太阳能热交换器的好处- 动力加热、冷却和热水系统与潜热储能相结合，最大限度地减少美国不同气候区住宅建筑的总体辅助燃料需求。引用:2020年虚拟会议论文

This paper presents an energy performance study of a novel solar thermal-powered heating, cooling and hot water system integrated with latent heat thermal energy storage (LHTES) by applying the system to cities in different ASHRAE climate zones across the United States. The study was carried out through calculations and comparisons of energy demands of home space heating, cooling and hot water loads; daily solar harvest; and auxiliary heat supply. In addition, a design method was implemented to size an LHTES system and solar collector for operation in different climate zones. Subject cities were selected randomly from seven ASHRAE climate zones across the United States. Analysis of energy performance showed that solar thermal-powered heating, cooling and hot water system integrated with an LHTES system could contribute to building energy savings. Energy savings were evaluated when a solar collector was coupled with an LHTES system and when only a solar collector was used. For example, an LHTES system in Miami, FL, selected from ASHRAE Climate Zone 1, was found to save about 67.72% of energy compared with a system without solar collectors or an LHTES, while the system with only a solar collector saves about 38.69%. An LHTES system in Duluth, MN, selected from ASHRAE Climate Zone 7, was found to save about 57.96% of residential building energy. When only a solar collector is used, energy savings is about 29.56%. Overall, this study demonstrates the benefits of a solar thermal-powered heating, cooling and hot water system integrated with latent heat thermal energy storage to minimize overall auxiliary fuel demand in residential buildings across different climate zones in the United States.
