W pracy przedstawiono wyniki rozważań dotyczących gruntowych wymienników ciepła, które mają współpracować w wymiennikiem w nawierzchni mostu (wiaduktu) w celu redukcji zmian temperatury nawierzchni. Pokazano wyniki symulacji numerycznej procesów ładowania magazynu i zmiany temperatury gruntu
The scope of the second part of this paper is to present the results of study on ground heat exchangers cooperating with heat exchanger placed within bridge surface. This type of technical solution was designed in order to reduce road surface short and long term temperature differences. Solar energy acquired from bridge surface was accumulated in ground. The system proposed in this paper was estimated in different constructional terms, heat exchanger configuration and processes conditions. Numerical simulation results for loading and unloading cycles have been presented. Moreover amount of energy accumulated in ground was calculated for different ambient conditions and heat exchanger geometry. The results confirm that the proposed system can reduce temperature differences in the bridge surface.
