HEATED ROADS - HEAT FLOW IN A HEATED PAVEMENT AS A FUNCTION OF CLIMATIC CONDITIONS AND MATERIAL PROPERTIES

UPPVAERMDA VAEGAR - VAERMEFLOEDET I EN UPPVAERMD VAEGKROPP SOM FUNKTION AV KLIMATFOERHAALLANDEN OCH MATERIALEGENSKAPER

The purpose was to form a basis for development of more adequate control systems and design methods for ground heating installations. By means of laboratory and field tests empirical relationships are derived between heat flow through the surface and climatic conditions such as air temperature, wind velocity, cloud conditions and precipation. The study is limited to those parts of the heating equipment installed in the pavement and concerns the most common types of equipment such as coils of pipes or cables. The results from the study are presented as mathematical equations for heat transfer through the surface as a function of surface temperature and air temperature and heat transfer coefficient in the surface as a function of wind velocity. The derived relationships between thermal outflow through a surface and different climatic conditions can be used in those boundary conditions necessary for the solution of the equation of heat diffusion.
