Computer modelling of infrared radiant heating in large enclosed spaces

The paper is focused on the application of the simulation in the field of the space heating systems, based on the infrared radiant heaters. In the first part is preview of different sw packages. In the second part there is a case-study of local heating design evaluation, where two different sw packages are used. Hefaistos is used to design the layout of the heaters, ESP-r is used to investigate the energy consumption and time dependent temperature variation.
