  1. 1. Energy Performance Simulation of Different Ventilation Systems in Sweden and Corresponding Compliance in the LEED Residential Rating System

    University essay from Högskolan Dalarna/Energiteknik

    Author : Patrick Boyle; [2020]
    Keywords : HVAC; IDA ICE; LEED; demand-controlled ventilation; heat recovery ventilation; energy efficiency; energy simulation;

    Abstract : The importance of energy efficiency in the operation of the built environment is becoming increasingly important. Energy use in the building sector has exceeded both transportation and industry, while within buildings heating, ventilation, and air conditioning has the greatest share. READ MORE

  2. 2. INTERMEDIATE-SCALE TESTS AND CONE CALORIMETER TESTS - FIRE BEHAVIOUR OF SELECTED FACADE MATERIALS

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Tanja Cernosa; [2020]
    Keywords : Fire behaviour; Intermediate-scale facade tests; cone calorimeter; stone wool; phenolic foam; WRB; Technology and Engineering;

    Abstract : In the last few years, the implementation of well-ventilated façades in buildings increased due to their improved energy performance. However, their double-wall construction due to the limited airflow within an air cavity represents a significant fire risk, since the flames that spread into the air cavity can elongate up to ten times.

  3. 3. Decreasing charging time of Lithium-Ion Battery by controlling temperature during the process

    University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Author : Seyedhafez Sadeghi Meykola; [2020]
    Keywords : Lithium-Ion; Battery; Cooling system;

    Abstract : In this report, which is written for Halmstad University and on behalf of Semcon, a mechanical design process was implemented to evaluate the possibility of executing a low-cost cooling system for one of the battery company’s products. The report started from the background of former studies to clarify the problem and finding existing solutions in the first step and following up with developing concepts based on gathered information from the literature study.

  4. 4. Monitoring air quality indicators and energy consumption in Dalarnas Villa during operation of a demand-controlled exhaust ventilation system

    University essay from Högskolan Dalarna/Energiteknik; Högskolan Dalarna/Energiteknik

    Author : Ian Garman; Ahmad Haj Ahmad; [2020]
    Keywords : Ventilation; demand control; airflow; frånluft; exhaust; carbon dioxide; CO2; indoor air quality; IAQ; air monitoring; villa; single family house; småhus; energy efficiency;

    Abstract : A real-world study was undertaken of the indoor air quality in a recently-built single family home in central Sweden, to establish whether demand controlled ventilation provided superior interior conditions, when compared with other air supply strategies, including the standard used by the Swedish buildings regulator. The property was highly airtight, with ventilation achieved using a forced exhaust system. READ MORE

  5. 5. Evaluation of decentralized ventilation system with heat recovery

    University essay from Lunds universitet/Energi och ByggnadsDesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Sunkavalli Kowshik Chowdary; [2020]
    Keywords : Decentralized ventilation; airflow; air draught; heat exchangers; tracer gas; Technology and Engineering;

    Abstract : Humans spend 90% of their times indoors, and maintaining a pleasant indoor environment is essential. Factors like human behaviour, combustion sources, cleaning supplies, affect the indoor environment, which could potentially affect the human health.the most common answer to controlling the indoor environment is a good HVAC system.
