Development of Space Heating and Domestic Hot Water Systems with Compact Thermal Energy Storage
July 2013 - PDF 2.28MB
Long-term, compact thermal energy storage (TES) is essential to the development of cost-effective solar and passive building-integrated space heating systems and may enhance the annual technical and economic performance of solar domestic hot water (DHW) systems. Systems should provide high energy storage density, charge and discharge temperatures that match the heat source used for charging and the intended load, adequate charge/discharge power, and employ storage materials that are stable over many cycles, non-toxic, environmentally safe. Moreover, these systems must compete effectively in the marketplace and therefore should provide an economic benefit compared to conventional heating and DHW systems, which have traditionally relied on sensible water storage.
