摘要

以塔林市中心为例，介绍了作为城市系统的区域制冷规划程序。详细描述了以下步骤：冷却需求确定、冷却生成计划和冷却过渡分析。根据提出的三种方法（平均比冷负荷、特定建筑的卫星图像分析、计算干式冷却器中的风扇数量和组合方法），评估区域的冷却能力估计为63.2MW，分析表明，用于自由冷却的海水可占全年制冷量的55%。使用余热的电动制冷机和吸收式制冷机可以满足区域冷却需求的其余部分。区域冷却网络设计用于三种场景：一台发电机组、两台发电机组和一个环形网络。尽管环形网络是最昂贵的选择，但这种类型的解决方案被认为是可行的，因为它将更容易连接新的消费者。

District Cooling Network Planning. A Case Study of Tallinn

The planning procedure for district cooling as an urban system was presented and carried out using the example of the Tallinn city centre. The following steps were described in detail: cooling demand determination, cooling generation planning and cooling transition analysis. Based on the three proposed methods (average specific cooling load, satellite imagery analysis of a specific building, counting the number of fans in dry coolers and the combination method), the cooling capacity of the evaluated district was estimated at 63.2 MW. In terms of cooling generation, the analysis shows that seawater for free cooling can cover up to 55% of the annual cooling consumption. Electric chillers and absorption chillers that use surplus heat can cover the rest of the district cooling demand. The district cooling network was designed for three scenarios: with one generating unit, with two generating units and a looped network. Despite the fact that the looped network is the most expensive option, this type of solution is considered feasible as it will make it easier to connect new consumers.

期刊介绍： The journal is an international interdisciplinary journal in Sustainable Energy Planning and Management combining engineering and social science within Energy System Analysis, Feasibility Studies and Public Regulation. The journal especially welcomes papers within the following three focus areas: Energy System analysis including theories, methodologies, data handling and software tools as well as specific models and analyses at local, regional, country and/or global level. Economics, Socio economics and Feasibility studies including theories and methodologies of institutional economics as well as specific feasibility studies and analyses. Public Regulation and management including theories and methodologies as well as specific analyses and proposals in the light of the implementation and transition into sustainable energy systems.
