Forskare fr\u00e5n Kuopio universitet och Kuopio arbetarh\u00e4lsov\u00e5rdsanstalt har utrett n\u00e5lv\u00e4rmev\u00e4xlarens f\u00f6rm\u00e5ga att f\u00f6rhindra fukt och mikrobiologiska skador i filtret.<\/p>

N\u00e5lv\u00e4rmev\u00e4xlaren placerades f\u00f6re tilluftsfiltret i studien. Den relativa fuktigheten och temperaturen i filtret \u00f6vervakades kontinuerligt vid tre punkter: 1) uteluft, 2) filter och 3) inomhusluft, under ungef\u00e4r ett \u00e5r.<\/span><\/p>

Den relativa luftfuktigheten i filtret h\u00f6lls under 70% och temperaturen \u00f6ver 3\u00b0C under alla \u00e5rstider. Filtret f\u00f6rblev torrt under hela sin livsl\u00e4ngd, \u00e4ven vi kraftigt sn\u00f6ov\u00e4der. Detta minskade behovet f\u00f6r filterbyten. M\u00e4ngden och arterna av mikrober som trivs i fuktiga f\u00f6rh\u00e5llanden var mindre i filterkammare \u00e4n i n\u00e5lv\u00e4rmev\u00e4xlaren, vilket visar att n\u00e5lv\u00e4rmev\u00e4xlaren f\u00f6rhindrar uteluftens mikrober att spridas till huvudfiltret.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
