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...
