Analytical Model of a New Integrated Collector Storage Heated at the Bottom with a Stratifier
Abstract
In the context of the French national plan for building energy renovation, we developed a new domestic hot water integrated collector storage (ICS) unit. In order to evaluate the annual performance of this specific bottom-heated ICS, an analytical model of the storage system was devised. The stratification device (plate) makes this model innovative, because the storage system is heated at the bottom, with a concentrated solar collector. The channel located between the plate and the upper wall of the storage assembly allows the deposition of hot water at the top (see Figure 1).
