Abstract

Modern district heating (DH) systems are one of the most promising heat supply solutions to reach the goal of fully decarbonised energy systems. The research goal of this paper is to evaluate the impact of installation of individual metering in DH systems on energy savings and emission reduction by application of machine learning algorithms and to predict how would this particular system upgrade measure influence the energy consumption and emissions. The research is focused on DH systems in Croatia. The results showed that dominant variable is the installation rate of individual metering devices (i.e. heat cost allocators - HCAs) and, for maximum energy saving, it should strive to 100% within a building. In that case, decrease in annual specific heat consumption in average building connected to a district heating system in Croatia is expected above 40 kWh/m2. Developed regression models show that apartments with installed HCAs could achieve about 40% reduction in heat consumption, compared to the apartments without HCAs.

迈向脱碳区域供热系统的一步:评估系统层面上个人计量的重要性

现代区域供暖（DH）系统是实现能源系统完全脱碳目标的最有前途的供热解决方案之一。本文的研究目标是通过应用机器学习算法来评估DH系统中安装单独计量对节能减排的影响，并预测这种特定的系统升级措施将如何影响能耗和排放。研究的重点是克罗地亚的DH系统。结果表明，主要变量是单个计量装置（即热成本分配器-HCA）的安装率，为了最大限度地节约能源，应努力在建筑物内达到100%。在这种情况下，克罗地亚与区域供暖系统相连的普通建筑的年比热消耗预计将下降40 kWh/m2以上。开发的回归模型表明，与没有安装HCA的公寓相比，安装HCA后的公寓可以减少约40%的热耗。
