ABSTRACT This paper discusses integration of twenty-first-century direct-exchange geothermal technology with nineteenth-century heat supply infrastructure to provide climate control at The Breakers, Newport, Rhode Island, U.S.A. In 1892, Cornelius Vanderbilt II built an 11,600 m2 Italian Renaissance style summer residence equipped with the most modern domestic technology available. This house retains original architectural finishes, furnishings, and a decorative arts collection, to give visitors insight into America’s Gilded Age. The mansion’s original design relied upon the ocean setting for its natural ventilation during summer occupancy; a convection heat system maintained the building through winter. A century later, risks to the collection due to extreme fluctuations in temperature and relative humidity along with rising energy costs prompted a climate modification feasibility study. The expense and complexity of conventional systems were deemed prohibitive, intrusive, and unsustainable. A high-efficiency geothermal heat pump system was chosen because it could generate conditioned, filtered air, re-use historic convection heat shafts, and significantly offset heating costs. Since going online in 2018, the system has stabilized the interior environment and considerably reduced fuel consumption. Discussion will include challenges encountered through design, installation and start-up, and assessment of environmental data.

用于历史建筑可持续气候控制的地热技术

摘要 本文讨论了 21 世纪直接交换地热技术与 19 世纪供热基础设施的整合，以在美国罗德岛州纽波特的 The Breakers 提供气候控制 1892 年，Cornelius Vanderbilt II 建造了一座 11,600 平方米的意大利文艺复兴风格配备最现代国内技术的夏季住宅。这座房子保留了原始的建筑饰面、家具和装饰艺术收藏品，让游客深入了解美国的镀金时代。这座豪宅的原始设计依靠海洋环境在夏季入住时实现自然通风；一个对流供暖系统在整个冬天维持建筑物。一个世纪后，由于温度和相对湿度的极端波动以及能源成本的上升，收藏品面临的风险促使进行了一项气候改变可行性研究。传统系统的费用和复杂性被认为是高昂的、侵入性的和不可持续的。之所以选择高效地热热泵系统，是因为它可以产生经过调节的过滤空气，重复利用历史悠久的对流热轴，并显着抵消供暖成本。自2018年上线以来，该系统稳定了车内环境，大幅降低了油耗。讨论将包括在设计、安装和启动以及环境数据评估过程中遇到的挑战。并且不可持续。之所以选择高效地热热泵系统，是因为它可以产生经过调节的过滤空气，重复利用历史悠久的对流热轴，并显着抵消供暖成本。自2018年上线以来，该系统稳定了车内环境，大幅降低了油耗。讨论将包括在设计、安装和启动以及环境数据评估过程中遇到的挑战。并且不可持续。之所以选择高效地热热泵系统，是因为它可以产生经过调节的过滤空气，重复利用历史悠久的对流热轴，并显着抵消供暖成本。自2018年上线以来，该系统稳定了车内环境，大幅降低了油耗。讨论将包括在设计、安装和启动以及环境数据评估过程中遇到的挑战。
