Description

This paper aims at clarifying the influence that the ventilation characteristics have on formaldehyde concentration in a house. The indoor formaldehyde concentration, ventilation rates and routes have been measured using an experimental house. The formaldehyde concentration has been calculated by characteristics of emission rates. It was found that the room in which polluted air flows is higher than that of an inflow of outdoor air. It is important to design ventilation routes into which polluted air doesn't flow. The calculated concentration is consistent with the measurement results excluding the period after being made airtight. After being sealed, the experiment value decreased gently as compared with the calculation value.
