摘要：

Thermal energy stores can significantly improve the efficiency and environment-friendliness of the heat supply by storing heat surpluses and supply heat to the consumer if necessary. Therefore, a high demand for cost-effective storage technologies with low energy losses exists. For hot water storage tanks using the displacement principle significant optimization potentials exist regarding currently at the market available storage technologies, in particular pressure vessels and flat-bottom tanks. A new tank design eliminates disadvantages and offers numerous benefits. A demonstrator with a new design was already built in cooperation with scientific and industrial partners as part of the OBSERW project in Nortorf (Germany). The demonstrator is a small-scale hot water storage tank with a volume of approx. 100 m(3). It allows numerous tests with low energy and time effort. The main novelty of the construction is an indoor floating ceiling, with the loading device (e.g. a radial diffuser) attached directly to it. A flexible connection allows the free movement of the floating ceiling between a top and bottom dead centre. This work describes the function of the storage tank and presents first operation experiences. (C) 2018 The Authors. Published by Elsevier Ltd.
