Simple Solutions for Controlling the Quality of Infiltrated Air through the Exterior Joinery Elements in Case of Calamities

Considering the more frequently events (volcanic eruptions, explosions, chemical contaminations etc.) which occur in nature, villages and industrial towns, the paper presents simple solutions and mechanical devices that allow the use of aeration function within habitable places for life protection and human health. These devices were the objective of some research studies that led to the determination of air amount needed for performing the activity under normal conditions in diverse habitable places (kitchens, living-rooms, bed-rooms or places with special destination in accordance with the imposed hygienic norms) and the determination of their constructive and functional features, implicitly. Experimental models devices for adjusting the aeration function in three constructive variants (with valve closure, with sliding cylinder element) were elaborated based on the performed studies and research. Based on the research studies performed by the author in Romania, EU countries and other areas, it is noticed that a small number of habitable places are endowed with such simple but efficient devices used for controlling the aeration function in case of calamities. These devices can be mounted in subassemblies of windows or in mixed elements; the production costs are reduced. The constructive systems, under normal exploitation conditions, allow the aeration/ventilation of habitable spaces ensuring the protection against insects as well. In case of calamities the slop panels can be equipped with special filters for air purification; these can be fixed without a special training. The proposed solutions may represent an alternative to the classical solutions for air conditioning that request high costs and available power source.
