Dynamic Temperature Simulation in District Heating Systems in Denmark Regarding Pronounced Transient Behaviour

Gabrielaitiene, Irena; Bohm, Benny and Sundén, Bengt LU (2011) In Journal of Civil Engineering and Management 17(1). p.79-87
Abstract
A dynamic performance of district heating systems was analysed with an emphasis on temperature profile distortion throughout a heating system network. Therefore, a modelling approach (the so-called node method) developed at the Technical University of Denmark was applied. For comparison purposes, commercial TERMIS software was also used in this work. Typical supply conditions were investigated in the considered district heating systems in Denmark. Large and sudden temperature changes in supply temperature were depicted in the district heating system in Madumvej while the pronounced transient supply conditions of temperature wave were exhibited in the district heating system in Naestved. Time-dependent consumer data from the district... (More)

Time-dependent consumer data from the district heating systems were applied to compare the results obtained from modelling approaches. Based on the analysis of temperature wave propagation through the network, it was noted that temperature wave spread unevenly on different locations of the network. (Less)
