<p>PROBLEM TO BE SOLVED: To solve the problem that purifying surrounding atmosphere supplied into buildings against expansion of environmental contamination in recent years has been desired; however, even if air conditioning and purification for circulating indoor air through a filter are carried out, there has not been provided an air ventilation device having means for confirming whether or not air restricts oxidization in human beings and animals and significant reduction state occurs.SOLUTION: This invention relates to an air ventilation supplying device and an oxidation- reduction confirming method in which circulation of air into a closed space (i.e. indoor space) utilized by human beings or animals is carried out and when air in the closed space shows a numerical value tending to oxidation under a before-after measurement in which an oxidation-reduction potential after passing by a prescribed time at the closed space is applied as an index, some impurity substances are removed from the surrounding atmosphere and the surrounding atmosphere is purified and the closed indoor space shows a reduction function through an operation of cross flow fan in a clockwise helical rotation passing through ceramic filters at a suction port and a discharging port installed at the prescribed locations in the closed space.</p> |
