Decentralized heat supply with seasonal heat storage systems: Comparison of different heating systems

Heat Loss Calculations in Heating Systems

Numerical Study of Heat Transfer and Aerosol Deposition in a Room Environment with Under-floor or Baseboard Heating Systems

In this study, heat transfer and aerosol deposition in the under-floor and baseboard heating systems have been investigated, numerically. The aim of this study is a comparison between these heating systems. This comparison obtains the optimal heating system with low suspended particles in the air. Computational fluid dynamic with Eulerian-Lagrangian method has been used to simulate fluid and pa...

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

Renewable Heat Supply through the Seasonal Coordinated Combination of Solarthermal and Geothermal Systems

Solarthermal plants can be supplemented with a seasonally operating geothermal deep probe and a heat pump, thus creating an energy supply system in which these devices support each other in an ideal manner. The system promises high shares of renewable energy and high efficiency of the solar and the geothermal system at the same time. This report introduces the concept of the system, explains it...

Joule heating and heat transfer in poly(dimethylsiloxane) microfluidic systems.

Joule heating is a significant problem in electrokinetically driven microfluidic chips, particularly polymeric systems where low thermal conductivities amplify the difficulty in rejecting this internally generated heat. In this work, a combined experimental (using a microscale thermometry technique) and numerical (using a 3D "whole-chip" finite element model) approach is used to examine Joule h...
