Résumé

The main objective of this paper is to present results from an on-going research project funded by the Research Council of Norway called KMB CREATIV – Competence project for Reduced Energy use through Advanced Technology InnoVations. The submitted paper focuses in particular on utilisation concepts of production of cooling by use of surplus heat exploitation in the fish industry. The seafood industry, including hatchery fish production, represents 29 % of the energy use of the food production industry in Norway. More than half of the energy use is electricity and 2/3 of total energy use is for cooling/freezing applications. Measures to reduce use of primary energy use for cooling production are therefor of major significance. The submitted paper presents results from a feasibility study of the possibilities of production of cooling water at a low temperature (about 0°C) from surplus heat at a high temperature level (above 80°C) by the use of absorption chillers. First, possible heat sources within different types of fish industry is analysed and second, possible synergy effects from cooperation between neighbour industries are analysed. To illustrate the second part, a case study is described. The feasibility study also includes an analysis of the need for water cooling in different processes and typical fish industries. The results will indicate which conditions that has to be in place in order to make the installation of a heat driven absorption chiller profitable in the Norwegian fish industry.
