Abstract A ventilation design was tested on models. The design uses convection to carry off air pollutants from workplaces. Through its use, pollution levels could be reduced by up to 90%, a much larger reduction than is possible through conventional ventilation systems. Heat exposure could be reduced by 60%. Application of the new concept to the modernization of an existing ventilation system confirmed the results obtained on the models. The modernized ventilation system reduced the exposure to coolants on the workplaces by 50%. Computer programmes were developed and applied which permit the calculation of the energy consumption as well as of the heat and air pollution levels connected with the ventilation system design.
