Design of a Thermochemical Seasonal Storage Demonstrator for a Single-Family House
Abstract
A seasonal storage demonstration unit coupled with an experimental single family house is being built as part of a solar test platform. It is designed to cover a large fraction of the winter heat load of the house by means of the solar energy collected during summer period. The core technology consists of an open-cycle thermochemical reactor with strontium bromide as reactant and operated with moist air, acting also as a heat carrier for the space heating system of the house. The installation includes a solar field, a storage tank, a reactor and a heat-management circuitry conceived with a high degree of flexibility to allow testing different operation modes. This article presents how the system was designed and optimized to reach the best performance both in terms of energy efficiency and compactness.
