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

    Author : Ulf Krüger; [1996]
    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

  2. 2. Probabilistic Modelling of Air Infiltration and Heat Loss in Low-Rise Buildings

    Author : Krystyna Pietrzyk; [2000]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ventilation; heat loss; reliability; leakage; air infiltration; risk analysis; thermal transmittance; probabilistic model; wind; building physics;

    Abstract : A probabilistic model (PROMO) of air exchange and heat loss in a low-rise building with a lightweight construction is proposed. The probability distributions of the air change rate and of the heat loss are the main outputs of the model. READ MORE

  3. 3. Distribution of Ventilation Air and Heat by Buoyancy Forces inside Buildings : an Experimental Study

    University dissertation from Stockholm : KTH

    Author : Claes Blomqvist; Mats Sandberg; Per Heiseberg; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building ventilation; thermal forces; buoyancy; gravity currents; large openings; heating; air quality; forced convection; free convection; TECHNOLOGY Civil engineering and architecture Building engineering; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur Byggnadsteknik;

    Abstract : The main task of the ventilation system in a building is to maintain the air quality and (together with the heating or cooling system) the thermal climate at an acceptable level within the building. This means that a sufficient amount of ventilation air at the appropriate temperature and quality must be supplied to satisfy thermal comfort and air quality demands and that this air is distributed to the parts of the building where people reside.

  5. 5. Air diffusion and solid contaminant behaviour in room ventilation a CFD based integrated approach

    University dissertation from Stockholm : KTH

    Author : Gery Einberg; Sture Holmberg; hazim Awbi; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technology; CFD modelling; airflow rate; ventilation efficiency; diffusers; solid contaminants; IAQ; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : One of the most fundamental human needs is fresh air. It has been estimated that people spend comparatively much time in indoor premises. That creates an elevated need for high-quality ventilation systems in buildings. The ventilation airflow rate is recognised as the main parameter for measuring the indoor air quality. READ MORE
