In this paper, the experimental analysis of a full-scale Domestic Electric Hot Water Storage Tank (DEHWST) with a capacity of 150 l is reported. The tank is equipped with three different inlets and two different outlets of practical interest. The dynamic mode of operation of the tank has been experimentally analyzed taking into account the six possible inlet-outlet port arrangements and water draw-off flow rates of 5, 10 and 15 l/min. The analysis is based on the transient temperature distributions of the outlet and inlet water flow and on the transient temperature profiles of the water inside the tank measured by an appropriate data acquisition system. Performance parameters to evaluate the thermal stratification in the tank and the discharging energy and exergy efficiencies are defined and calculated from the experimental data. The characteristic performance of the tank with different inlet-outlet port configurations is analyzed and the best one is identified and proposed to use in practice.

“…This can be explained because of the water temperature distribution inside the tank, as a result of the water temperature stratification phenomena. The water temperature stratification in the storage tank evaluated in the present study was analyzed in a previous research developed by Fernández-Seara et al [19]. Their experimental results showed that at the upper half of the tank the water temperatures measured at different layers were similar whilst in the lower half of the tank temperature gradients were observed amongst the waters layers.…”

In this paper heat transfer experimental data is presented and compared to general correlations proposed in the literature for transient laminar free convection from a vertical cylindrical tank.The experimental data has been obtained from heating and cooling experiments carried out with a cylindrical full-scale hot water storage tank working under real operating conditions. The experimental device and the data acquisition system are described. The calculation procedures

“…Leduc and Van Kann (2013) focused on sustainable energy harvesting on urban areas ending up to smarter regions. A lot of studies on water heating with the use of storage tanks have estimated that this energy could account up to 30 % of the total electricity consumption of the building (Rankin and Rousseau 2007;Saidur et al 2007;Fernández-Seara et al 2007).…”

In this paper cold and thermal storage options via wind energy surplus are examined aiming to enable higher wind integration. A case study in Greece with an installed wind farm (WF) was investigated reviewing the possibilities for higher renewables integration using thermostatically controlled loads (TCLs), analysing thermal and cold storage possibilities according to the needs of the local municipalities. The basic aim is to describe the idea of an aggregated system with a number of residential freezers, in order the wind power to be stored in the residential cold stores aiming at maximizing the benefit to the grid, utility or cold store owner avoiding at the same time wind curtailment. In addition, for thermal storage, by calculating thermal losses of the building, ventilation losses and adding up internal thermal gains of the building the space heating needs can be calculated.
