Abstract:
In a project conducted in a test house on the grounds of ECN, the applicationof a water filled bag tank for medium-term storage of heat for domestic space heating and hot tap water is tested and optimised. Acceptable values of the heat capacity and the thermal resistance between the bag tank and its environment depend both on local weather conditions and the demand for space heating and hot tap water. With the aid of simulations, acceptable ranges for these values are found and predictions are made about the contribution of the bag tank to the energy demand of the test house. The paper presents the results of the simulations. At the time being, measurements are initiated to determine the actual performance of the bag tank in the test house. These will be reported in separate papers at a later stage.
