热虹吸管-冷却器混合系统（TCHS）将干热排出装置热虹吸管冷却器（TSC）的控制与开放式冷却塔集成在一起。这种新型散热系统结合了设备和控制装置，实现了“水的智能使用”，在最有利的情况下使用蒸发冷却，然后在系统运行和环境天气条件允许的情况下节约用水，并朝着增加干燥感观冷却的方向进行调节。创新的风扇控制策略确保了节水和寄生风扇能量之间最经济的平衡。 TSC独特的低压降设计允许水通过TSC蒸发器直接冷却，而不会在低温环境条件下出现爆管风险。江森自控与两个国家实验室——科罗拉多州戈尔登的国家可再生能源实验室（NREL）和新墨西哥州阿尔伯克基的桑迪亚国家实验室——合作，于2016年上半年在NREL的高性能计算（HPC）数据中心部署TSC作为试验台。该HPC数据中心位于能源系统集成设施（ESIF）内，年平均用电效率为1。 自2012年起为06或更高。温水液体冷却用于捕获计算机系统直接向水中产生的热量；这些废热要么被重新用作ESIF建筑中的主要热源，要么被蒸发冷却排出。该数据中心是校园内最大的水和电需求来源，在过去一年中使用了约7600立方米（200万加仑）的水，每小时平均互联网技术负荷接近1兆瓦（340万Btu/h）- -因此，在继续高效运行数据中心的同时大幅减少水资源的使用是一个非常重要的问题。由于新墨西哥州实验室的气候与科罗拉多州实验室的气候相似，且新墨西哥州的实验室数据中心每小时平均利用8.5 MW（2900万Btu/h）的水资源，因此ESIF正在部署的这种新型散热系统引起了人们的兴趣，同时也是现场最大的用水者之一。除了描述TSC的安装及其与ESIF的集成外，本文还重点介绍了全排热系统模拟程序，该程序用于每小时分析不同运行场景下整个系统的能耗和耗水量。 后续论文将详细说明测试结果。科罗拉多州实验室对TSC性能的评估还将确定新墨西哥州实验室的未来路径，以便在大规模系统中部署，不仅用于数据中心，也可能用于整个站点。引文:2017年冬季会议，内华达州拉斯维加斯，会议论文

The Thermosyphon Cooler Hybrid System (TCHS) integrates the control of a dry heat rejection device, the thermosyphon cooler (TSC), with an open cooling tower. A combination of equipment and controls, this new heat rejection system embraces the "smart use of water," using evaporative cooling when it is most advantageous and then saving water and modulating toward increased dry sensible cooling as system operations and ambient weather conditions permit. Innovative fan control strategies ensure the most economical balance between water savings and parasitic fan energy. The unique low-pressure-drop design of the TSC allows water to be cooled directly by the TSC evaporator without risk of bursting tubes in subfreezing ambient conditions.Johnson Controls partnered with two national laboratories--the National Renewable Energy Laboratory (NREL) in Golden, Colorado, and Sandia National Laboratories in Albuquerque, New Mexico--to deploy the TSC as a test bed at NREL's high-performance computing (HPC) data center in the first half of 2016. Located in the Energy Systems Integration Facility (ESIF), this HPC data center has achieved an annualized average power usage effectiveness rating of 1.06 or better since 2012. Warm-water liquid cooling is used to capture heat generated by computer systems direct to water; that waste heat is either reused as the primary heat source in the ESIF building or rejected using evaporative cooling. This data center is the single largest source of water and power demand on the campus, using about 7,600 m3(2.0 million gal) of water during the past year with an hourly average Internet technology load of nearly 1 MW (3.4 million Btu/h)--so dramatically reducing water use while continuing efficient data center operations is of significant interest. This new heat rejection system being deployed at the ESIF has gained interest because the climate at the laboratory in New Mexico is similar to that of the laboratory in Colorado, and the laboratory data centers in New Mexico utilize an hourly average of 8.5 MW (29 million Btu/h) and are also one of the largest consumers of water on-site.In addition to describing the installation of the TSC and its integration into the ESIF, this paper focuses on the full heat rejection system simulation program used for hourly analysis of the energy and water consumption of the complete system under varying operating scenarios. A follow-up paper will detail the test results. The evaluation of the TSC's performance at the laboratory in Colorado will also determine a path forward at the laboratory in New Mexico for possible deployment in a large-scale system not only for data center use but also possibly site wide.
