2. 1. Some Factors Influencing Thermal Comfort and Air Quality in Residential Buildings. Field Measurements and Laboratory Tests

   Author : Ulf Krüger; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ventilation; air intakes; thermal comfort evaluation; air velocity; indoor air quality; air supply devices; occupation zone; air temperature fluctuations;

   Abstract : The main prerequisite for applying a specific ventilation system in residential buildings is that the demands set upon the indoor air quality and thermal climate can be satisfied. If this cannot be guaranteed using a simple exhaust system, a system with treated supply air, i.e. balanced ventilation, should be considered. READ MORE
