Heat exchanging asphalt layers

Abstract

This final report describes the work of a research team during an so called “European Project Semester” (EPS)1 at the Artesis Hogeschool, Antwerp. The aim of the project was to describe a state of the art Heat Exchanging Asphalt Layer system with an underground thermal heat storage system. Together they are used to collect the heat and cold of an asphalt pavement during summer, respectively winter, and store it in the underground. The energy is than used in the following season to either cool the building and the road in summer, or to heat both in winter. The focus lays on the necessary heat exchangers and the storage systems. Furthermore a basic approach to calculate the energy output of such a system is included, with a focus on a laboratory prototype of such an asphalt collector. The main objective is to give a basic understanding of the functions of a HEAL-system.
