ESSENTIAL COMPLEMENT TO ANY AIR-CONDITIONING

From the office at the house while passing by the medical units, the rooms of spectacles, restaurants etc., the air-conditioners bring an clear comfort but also attack our organisms

The harmfulness of the air-conditioners, humidifiers, ventilators and other conditioners of air is not any more to show;: "  the recycling of the major part of the circulating air, impossibility of retaining micro the pollutants and the infectious germs which accompany them, the existence of true culture mediums in the vats of humidification, involve a risk of dissemination of germs of which some are particularly dangerous... ¯ ". (1)

 The use of varied devices of " air-conditioning ", intended in theory to increase the comfort of the users and to improve quality of the air of the habited buildings, was balanced finally by a severe and quasi-general aggravation of the medical state of the treated buildings, sometimes even in terms of serious risks of bio-contamination (Reports of the I.N.S.E.R.M., conference of 1986 and following, in particular).  This situation results from two factors specific to the methods used: 

- impossibility of overcoming the bio-contamination, in particular viral nature, with the techniques " ~ of cleansing " ~ ¯ used; 
 - the dissemination of the micro pollution support of bio contamination in the whole of the buildings thus " treated ", for lack of really effective and sour systems of purification.  (2)

Already serious in themselves, these two facts double like always in such a case of a very strong disturbance of the electric state of the air of the places:  quasi-total disappearance of the last negative charges, appearance and maintenance of great positive charge closely related to micro-particles present;  this last effect results from the " treatment by turbine action " of the air, of the wrenching of electrons which results from it, of the capture of the latter by the walls of the conduits, and the final injection of the positive charge thus create.(2)

Thus, office or rest room, all are the place of a sometimes severe disordered state of the physical and biological characters of their atmosphere   

 From where harmful effects proven by an increasing fraction of the People working in the confined buildings with " air conditioning ": 

- ORL disorders (irritations of the throat, anginas, colds frequent, sinusitis)
- Ocular disorders (smarting, conjunctivitis )
- Respiratory disorders (bronchitis , lung disease, legionnaire?s disease, influenzas)
- Various disorders (headaches, prolonged tirednesses, phenomena allergic, Malayan, itchings, urticarias, irritabilities, losses of vigilance) '

the major concern of the fitters of air-conditioners must be " the safeguarding of the health of the occupants of the building to be equipped ". 

They must, for that, to take account of the ionic balance of the air inside the buildings, namely: 

·        a polluted air comprises in strong majority of the large positive ions

·        a healthy air, contrary, has a strong majority of negative ions

 the solution   
 the massive injection of negative ions in a polluted micro air then involves always the elimination of micro the pollutants and the restoration of a healthy air.
