隔离病房隔离效果的研究(3)

Study on isolation effects of isolation wards (3)

基于大气尘实验,研究了隔离病房开门时温差对污染物外泄的作用.结果显示,温差作用是一般压差作用抵消不了的;2℃温差时污染物交换量比0℃温差时增加50%左右;缓冲室可对温差作用引起的污染物交换起到15～30倍的动态隔离作用.

Based on the atmospheric dust experiment, researches the contaminant air exchange caused by the temperature difference while opening the door of isolation wards. Concludes that the undesired effect of temperature difference could not be eliminated just by the negative pressure difference between adjacent rooms, that the contaminant air exchange would increase about 50% in the temperature difference of 2℃ than that in the temperature difference of 0℃, and that such contamination could be reduced to about 1/31～1/16 with the helo of buffer rooms.
