Electric Light and Heat

Lecturer:

Jan Kyncl (gar.), Jiří Habel (gar.)

Tutor:

Jan Kyncl (gar.), Jiří Habel (gar.), Marek Bálský, Ladislav Musil

Supervisor:

Department of Electroenergetics

Synopsis:

The aim of the course is to get an overview of light quantities and their measuring, light sources, luminaires, and the fundamentals of interior and exterior lighting and creation of visual comfort. In the second part student learns fundamental laws of heat transfer, design and use of resistance, dielectric, induction and arc electroheat devices. The course ends by introduction into the theory of the human thermal comfort and interior heating.
