An accurate characterization and prediction of heat loads in buildings connected to a District Heating (DH) network is crucial for the effective operation these systems. The high variability production process DH networks with low supply temperatures derived from incorporation different sources increases need demand models. This paper presents novel data-driven model heating network. built on so-called Q-algorithm fed real data 42 smart energy meters located Tartu (Estonia). These deliver...
Industrial waste heat recovery shows significant potential for increasing energy efficiency in industry. However, to design strategies that exploit this potential, it is necessary have data about the quantity and characteristics of industrial flows. This information not always readily available many companies do even a systematic record these Hence, bottom-up methodologies estimate by means key transfer figures are useful tools within field. In present article, four different methods applied...
