Providing welfare status for personnel of industrial plants is necessary and also emphasized in all standards. Preparing fresh, cool and clean air especially in warm seasons is one of the most important duties of plant owners to keep workers safe and healthy. Although in many workshops some cooling and air-conditioning systems (commonly mixing ventilation systems) were installed, most of them have economical problems and may not be energy efficient as the entire room volume gets cooled. The purpose of this article is presenting an executive improved solution in architecture to upgrade existing Mixing Ventilation Systems (MVS) by intervening in architectural variables. The new solution is compared with a traditional MVS taking into account technical and economic performances. The study was carried out resorting to experimental measurements on a single-diffuser pilot installation of the existing MVS in an actual industrial facility. The research method is experimental: the thermometry tests and interviews with workers which were carried out after initial observations and the case study selection. After that some interventions in architecture were impelled and the testes were repeated. To confirm the results, after interventions, a questionnaire was given to the operators, and their answers were registered. A comparison was fulfilled with respect to energy consumption and also the consumed power was checked before and after the interventions. The results demonstrate that architectural alterations based on this research can improve the quality of existing MVS (Satisfactions of the workers approved the interventions) and reduce the energy consumptions. It could be generalized.
