Abstract

Due to the fluctuated availability of solar energy, the solar thermal energy systems are designed by simulation as to have a system which will satisfy the loads as expected. The thermal storage tanks are existing since a long time but however there is still research going on and new novel tanks are introduced. One such tank is the Hybrid Quattro thermal storage tank from Sailer GmbH. This storage tank have new patented lances, which helps in stratification of the tank and thus higher efficiency of the energy storage without mixing of the layers in the tank. For designing of an energy system with this storage tank, a simulation model of this tank is required. Thus a test of this storage tank is done and the parameters were identified which later was used to build up a component model for storage in TRNSYS software using the type 340 storage tank model. This paper explains the process of identifying parameters from a real storage tank to a simulation model which can be used further for simulating a storage tank which would also make possible for the storage tank to be optimized for a development in the efficiency for the system performance.
