Type of article: Article

Summary

THE AUTHORS FIRST CLASSIFY THE DIFFERENT CONTAMINANTS WHICH CONCERN THE AIR QUALITY INSIDE RESIDENTIALBUILDINGS. FOR EACH OF THEM THE ACCEPTABILITY LIMITS AND THE MAIN SOURCES ARE POINTED OUT. CALCULATION MODELS FOR THE RELEASE AND THE TRANSFER OF POLLUTANTS ARE ALSO PROPOSED. NEXT, THE DIFFERENT TYPES OF AIR CONDITIONING INSTALLATIONS AND THEIR COMPONENTS ARE ANALYZED FROM THE POINT OF VIEW OF APTITUDE FOR PROMOTING HIGH AIR QUALITY. THE DISTRIBUTION OF POLLUTANTS INSIDE A BUILDING DEPENDS ON THE COMBINED EFFECTS OF THE WIND PRESSURE ON THE EXTERNAL SURFACES, OF THE THERMAL GRADIENTS INSIDE, AND OF THE MECHANICAL SYSTEM FOR AIR EXTRACTION. THE AIR CONDITIONING IN-STALLATION ITSELF CAN BE A MAJOR SOURCE OF POLLUTION, ESPECIALLY WHEN MAINTENANCE IS INADEQUATE. FOR INSTANCE, SERIOUS PROBLEMS DUE TO CORROSION AND MICRO-ORGANISM PROLIFERATION CAN ARISE FROM THE PRESENCE OF STAGNANT WATER IN THE VARIOUS COMPONENTS. E. F.
