  1. 1. Distribution of Ventilation Air and Heat by Buoyancy Forces inside Buildings An Experimental Study

    University dissertation from Stockholm : KTH

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

    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.

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

    University dissertation from Stockholm : KTH

    Author : Gery Einberg; KTH.; [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

  3. 3. Controlling Indoor Climate. Passive cooling of residential buildings in hot-humid climates in China

    University dissertation from Department of Building Science, Lund Institute of Technology

    Author : Zhiwu Wang; Lund University.; Lunds universitet.; [1996]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building construction; China; hot humid climate; thermal comfort; Computational Fluid Dynamics CFD; residential buildings; roofs; indoor climate; passive cooling; cross-ventilation;

    Abstract : Overheating is a paramount problem in residential buildings in hot-humid climates in China during summer. This study aims to deal with the overheating problem and the problem of poor air quality in dwellings. READ MORE

  4. 4. Experimental and numerical investigations of a ventilation strategy – impinging jet ventilation for an office environment

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Huijuan Chen; Högskolan i Gävle.; Linköpings universitet.; Linköpings universitet.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Impinging jet ventilation; room air distribution; thermal comfort; ventilation performance; turbulence modelling; CFD;

    Abstract : A well-functioning, energy-efficient ventilation system is of vital importance to offices, not only to provide the kind of comfortable, healthy indoor environment necessary for the well-being and productive work performance of occupants, but also to reduce energy use in buildings and the associated impact of CO2 emissions on the environment. To achieve these goals impinging jet ventilation has been developed as an innovative ventilation concept. READ MORE

  5. 5. Simulation of historic buildings for enhancement of preservation and energy performance – issues and methods

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Torun Widström; KTH.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building simulation; historic buildings; energy performance; damage risk; mould; thermal bridges; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : Historic buildings are often particularly poorly insulated and difficult to heat, and are also at risk for several reasons. These include potential lack of use due to low thermal comfort leading to low or no profitability, damage risks due to over and under-climatization and risks due to climate change altering the boundary conditions that they were built for.
