Design and Assessment of District Heating Systems with Solar Thermal Prosumers and Thermal Storage

Thermal Transients in District Heating Systems

Heat fluxes in a district heating pipeline systems need to be controlled on the scale from minutes to an hour to adjust to evolving demand. There are two principal ways to control the heat flux keep temperature fixed but adjust velocity of the carrier (typically water) or keep the velocity flow steady but then adjust temperature at the heat producing source (heat plant). We study the latter sce...

Optimal Design of Cogeneration Systems in Industrial Plants Combined with District Heating/Cooling and Underground Thermal Energy Storage

Combined heat and power (CHP) systems in both power stations and large plants are becoming one of the most important tools for reducing energy requirements and consequently the overall carbon footprint of fundamental industrial activities. While power stations employ topping cycles where the heat rejected from the cycle is supplied to domestic and industrial consumers, the plants that produce s...

Heat storages in Swedish district heating systems An analysis of the installed thermal energy storage capacity

Thermal Performance Rating of Solar Water Heating Systems in ASEAN

Solar water heating (SWH) systems are gaining popularity in ASEAN in the midst of increasing number of affluent population in society and environmental concerns from seemingly unchanged reliance on fossil-based fuels. The penetration of these systems and technologies into ASEAN markets is a welcome development; however there is a need for the method of assessment of their thermal performances. ...

Solar District Heating with Seasonal Storage in Attenkirchen

Energy conservation through energy storage combined with intensive use of renewable energies will support the effort to meet the objectives of reduction of climatic gases formulated in the Kyoto protocol. Potential studies have shown that in Germany about 20 – 25 % of the end-energy consumption for space heating and domestic hot water can be covered by solar energy. Solar district heating with ...
