THERMAL ENERGY FROM WATERCOURSES FOR TEMPERATURE CONTROL OF ASPHALT PAVED SURFACES

TERMISK ENERGI UR VATTENDRAG FOER TEMPERATURREGLERING AV ASFALTYTOR

This project deals with extraction of thermal energy from water courses, energy storage in the ground and temperature control of asphaltic surfaces. A pilot plant with possibilities to test new equipment and new methods was built. The tests during the winter showed that the lakes and watercourses are a reliable and stable heat source. It is especially advantageous to let this heat source deliver low temperature basic energy continuously the whole year. Large quantities of oil can be saved if oil heating of residential areas was replaced with thermal energy from water courses. From cost, management and environmental points of view this energy source also seems to be at least as good as oil. Effect of energy demand to keep a bituminous surfacing dry and clean, and to prevent skidding, is evaluated. A new heat exchanger is dealt with. (TRRL)
