In a multienergy framework, power-to-heat technology is becoming increasingly attractive. This interest is mainly due to the possibility of exploiting excesses and unbalances of electricity, which are becoming more and more common with the increasing capacity of the renewable sources. An interesting option consists in using heat pumps to convert excess of electricity produced by photovoltaic systems (especially in the midday hours) into cold to be provided to district heating and district cooling networks. This article aims to propose a methodology to select the best heat pump location in district cooling system. The analysis is performed with the aim of minimizing the cost of network construction and pumping. The procedure includes the best heat pump location and the design of the pipeline. Results show that distributed heat pumps allow one reducing both the costs and the average pipeline diameters by about 50% with respect to concentrated production. Furthermore, the optimal location of distributed heat pumps allows reducing costs of about 7% with respect to a uniformly distributed production.

区域供冷系统中电冷技术的优化配置

在多能源框架中，电热技术正变得越来越有吸引力。这种兴趣主要是由于利用电力过剩和不平衡的可能性，随着可再生能源容量的增加，这种情况变得越来越普遍。一个有趣的选择包括使用热泵将光伏系统（尤其是在中午）产生的多余电力转换为冷量，以提供给区域供热和区域供冷网络。本文旨在提出一种在区域供冷系统中选择最佳热泵位置的方法。进行分析的目的是尽量减少网络建设和抽水的成本。该程序包括最佳热泵位置和管道设计。结果表明，对于集中生产，分布式热泵允许将成本和平均管道直径降低约 50%。此外，分布式热泵的最佳位置允许相对于均匀分布的生产降低约 7% 的成本。
