Low temperature district heating (LTDH) offers innovative opportunities for an efficient heat supply. For the analysis of LTDH an exergy-based evaluation method was developed were energy as well as economic and sustainability aspects are combined. To verify the applicability of the method and to derive the advantages and disadvantages of different supply technologies the method is applied to case studies.
Low temperature district heating (LTDH) offers possibilities for efficient heat supply based on renewable energies. For the analysis of LTDH, the exergetic assessment is a suitable method. Hence, an exergy-based assessment method was developed in which energy as well as economic and sustainability aspects are combined. As part of a technology comparison, the method is applied to case studies to verify the applicability of the assessment approach. The approach highlights innovative supply solutions by identifying the advantages and disadvantages of different supply strategies.
