  1. 6. Ventilation and window opening in schools, Experiments and Analysis

    Författare :Birgitta Nordquist; Avdelningen för Installations- och klimatiseringslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat exchanger efficiency; duct design; balancing; disturbance; tracer gas measurements; analytical model; window opening; single-sided ventilation; ventilation; schools; sensitivity analysis; Building construction; Byggnadsteknik;

    Sammanfattning : The objective of this thesis is to study the application of ventilation in schools buildings. A number of studies of the application of different forms of ventilation are presented. The main part of the thesis focuses on window opening in a classroom. Analytical models for calculation of the air change caused by window airing are proposed. LÄS MER

    Sammanfattning : This thesis introduces and describes a new experimental setup for examining the effects of pulsating inflow to a ventilated enclosure. The study aimed to test the hypothesis that a pulsating inflow has potential to improve ventilation quality by reducing the stagnation zones through enhanced mixing. LÄS MER

    Sammanfattning : Indoor air quality directly affects the comfort, performance, and well-being of occupants. Indoor pollution can cause immediate or long-term health effects and has been responsible for 4.1% of global deaths in recent decades. LÄS MER

  5. 9. Transmission of Infectious Bioaerosols : Sources, transport and prevention strategies for airborne viruses and bacteria

    Författare :Malin Alsved; NanoLund: Centre for Nanoscience; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bioaerosol; infectious disease; Norovirus; Airborne bacteria; aerosols;

    Sammanfattning : Infectious diseases that can be transmitted via air often spread rapidly, sometimes causing large epidemic and pandemic outbreaks. As an increasing number of people live in crowded urban environments, and with frequent and long-distance traveling across the world, infectious diseases can spread even faster. LÄS MER

  7. 10. Towards sustainability with building services systems : – by focusing on material choices, energy use and thermal indoor climates in residential buildings

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; residential apartment buildings; building services systems; energy use; hvac; hydronic heating system; heating control; feedback control loop; indoor temperature measurements; individual metering and billing; indoor temperature variations; thermal comfort; vertical temperature gradient; case study;

    Sammanfattning : For a development to be considered sustainable, social, economic and environmental requirements must be met. The Swedish sustainable development goals, based on Agenda 2030, contain 16 national environmental quality goals. The National Board of Housing, Building and Planning is responsible for achieving the goal "A good built environment". LÄS MER
