制冷与空调

介绍了在“双碳”战略背景下，深圳市某金融数据中心的间接蒸发冷却空调系统应用情况。结合深圳地区的气候条件，分析了该数据中心间接蒸发冷却空调各运行模式的切换点、全年运行时长、经济性、碳排放量等问题。并通过工程的实际测试证明，数据中心建设成多层的形式，冷源设备间接蒸发冷却空调(AHU)具备高分子聚合物材料的板式换热芯体、高压微雾布水方式、分散直膨式(DX)补冷等特点会是能效最优的组合。在未来数据中心的发展中，可依照该工程模式进行建设，达到数据中心全生命周期内的收益最大化。

This paper introduces the application of indirect evaporative cooling air conditioning system in a financial data center in Shenzhen under the background of “dual carbon” strategy. Combined with the climate conditions in Shenzhen, the switching points of various operation modes of indirect evaporative cooling air conditioners in the data center, annual operation duration, economy, carbon emissions and other issues were analyzed. And the actual test of the project proves that the data center is built into a multi-layer form, and the indirect evaporative cooling air conditioner(AHU), a cold source equipment, has the characteristics of plate heat exchange core made of polymer materials, high-pressure micro mist water distribution, and distributed direct expansion(DX) cooling, which will be the best combination of energy efficiency. In the development of the data center in the future, it can be constructed according to the project mode to maximize the benefits of the data center in the whole life cycle.
