dc.description.abstract | Thermal energy storage (TES) can be applied to reduce peak heating and cooling loads in buildings and to improve the performance and reliability of the heat supply system. For short-term TES, phase change materials (PCM) are a compact and efficient alternative. At the Bergen University College in Norway, three ammonia chillers/heat pumps cover the base load for heating and cooling. To reduce the required chiller capacity, PCM cold storage tanks have been installed. The present study evaluates the PCM-TES system in detail through modelling and analysis of measurement data. To gain more understanding of the freezing and melting processes, a dynamic model for the PCM-TES was developed in Dymola. The simulation results were validated towards measurement data. The model allows better understanding of the heat transfer characteristics of the PCM-TES, and enables more sophisticated dimensioning and design of future PCM-TES systems. | nb_NO |
