VENTILATION AND MOISTURE SOURCES IN APARTMENTS

摘要

Moisture related problems, growth of fungi and an abundance of house dust mites harm the health. Suggested alleviating measures include increased ventilation, the use of biocides, improved moisture and temperature insulation, or reduction of humidity sources. This study was done to investigate the importance of user behavior; ventilation and construction details for humidity retted problems. In a cross sectional study in Danish apartment's air exchange rate, relative humidity and temperature of room air was logged during winter with average daily outside temperatures in the range -5 to 8°C. Information on user behavior was obtained by questionnaires. A mass balance model based on humidity in room air, temperature and air change rate was used to show that moisture production is significant related to air change rates. Laundry drying was significant for humidity of room air. No significant relation between air change rates and humidity was found in the study.
