Ce travail de th\u00e8se \u00e9tudie l\u2019opportunit\u00e9 d\u2019int\u00e9grer des pompes \u00e0 chaleur \u00e0 absorption (P\u00e0Cs) dans les sous-stations des r\u00e9seaux de chauffage (RdC). L\u2019enjeu est de contribuer \u00e0 la meilleure efficacit\u00e9 \u00e9nerg\u00e9tique des RdC et d\u2019y permettre une meilleure int\u00e9gration des \u00e9nergies renouvelables. Trois modes de fonctionnement de la P\u00e0Cs sont propos\u00e9s pour r\u00e9pondre aux besoins des b\u00e2timents tout au long de l\u2019ann\u00e9e \u00e0 partir de la chaleur du RdC, en :<\/div>\n
    \n
  • augmentant localement la temp\u00e9rature disponible du RdC pour couvrir les besoins de chaleur \u00e0 haute temp\u00e9rature des b\u00e2timents, \u00e0 partir d\u2019un RdC basse temp\u00e9rature par exemple ;<\/li>\n
  • rafraichissant les b\u00e2timents \u00e0 partir de la chaleur du RdC, en \u00e9t\u00e9 par exemple ;<\/li>\n
  • am\u00e9liorant le transfert de chaleur entre le RdC et le b\u00e2timent.<\/li>\n<\/ul>\n

    Pour comparer les performances atteintes avec plusieurs couples absorbant-r\u00e9frig\u00e9rant, un mod\u00e8le en r\u00e9gime permanent a \u00e9t\u00e9 d\u00e9velopp\u00e9 pour simuler la P\u00e0Cs dans des conditions de fonctionnement typiques des sous-stations de RdC, pour les trois modes de fonctionnement consid\u00e9r\u00e9s. Ce mod\u00e8le a permis d\u2019identifier le couple NH3-LiNO3 comme couple le plus pertinent. Puis, un mod\u00e8le dynamique a \u00e9t\u00e9 d\u00e9velopp\u00e9 pour simuler le syst\u00e8me lors de variations de conditions de fonctionnement.<\/p>\n

    Un prototype exp\u00e9rimental d\u2019une puissance froid de 3 kW, utilisant le couple NH3-LiNO3, a \u00e9t\u00e9 dimensionn\u00e9, construit et test\u00e9 pour valider la faisabilit\u00e9 du concept, quantifier ses performances et valider le mod\u00e8le num\u00e9rique. Suite \u00e0 cette validation, le mod\u00e8le a \u00e9t\u00e9 utilis\u00e9 pour \u00e9tudier la pertinence de l\u2019utilisation de P\u00e0Cs en sous-station de RdC pour r\u00e9pondre aux besoins de chaleur et de froid des b\u00e2timents et ainsi am\u00e9liorer les performances du RdC et favoriser l\u2019int\u00e9gration de nouvelles sources d\u2019\u00e9nergie renouvelable \u00e0 basse temp\u00e9rature.<\/div>\n

    Abstract<\/strong><\/span><\/h3>\n
    This work studies the opportunity to integrate absorption heat pumps (AHP) in substations of district heating networks (DHN). The challenge is to improve the energy efficiency of DHN and to allow better integration of renewable energies. Three AHP operating modes are possible to satisfy the needs of buildings throughout the year by using DHN heat, by : (i) locally increasing the available temperature of the DHN to satisfy the high-temperature heating needs of buildings, for example from a lowtemperature DHN; (ii) air conditioning of the buildings from the heat of the DHN, for example in summer; (iii) improving the heat transfer between the DHN and the building. To compare the performances reached with several absorbent-refrigerant pairs, a steady-state model was developed. The model simulates the AHP under typical operating conditions of DHN substations for the three considered operating modes. According to the model, the NH3-LiNO3 pair was identified as the most relevant one. Then, a dynamic model was developed to simulate the system under varying operating conditions. An experimental prototype with 3 kW cooling capacity was dimensioned, built and tested with the NH3-LiNO3 couple, to validate the feasibility of the concept, quantify its performance and validate the numerical model. Following this validation, the model was used to study the relevance of the use of AHP in DHN substations to satisfy the heating and cooling needs, improve the DHN performances and promote integration of new low temperature renewable energy sources.<\/div>\n
