  1. 1. Demand controlled ventilation : Impact on energy use and indoor environmental quality

    University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Author : Therese Ottosson; [2023]
    Keywords : ;

    Abstract : European buildings account for a significant share of the energy-related emissions in Europe. Addressing the increasing energy use and its contribution to greenhouse gases (GHG) is internationally recognized as crucial, and emissions must be halted. READ MORE

  3. 2. The Development and Testing of Low-Cost Heat Transfer Enhancements for Solar Dryers

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Hoda Mahmoodi; [2023]
    Keywords : Solar dryer; Bhutan; Drying rate; Solar absorber; Technology and Engineering;

    Abstract : In the mountainous regions of Bhutan and Nepal, post-harvest losses cause significant challenges for producers. Open air sun drying is usually used by farmers to preserve their produce. There are many disadvantages to this method. READ MORE

  4. 3. Optimization of comfort-related energy and thermal comfort for commuter trains : A case study of Stockholm commuter trains

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Jimmy Lidén; [2023]

    Abstract : Today, energy efficiency is an increasingly important question in which progress is accelerating. One of the high electricity demand energy users is public transport. In addition, passenger satisfaction with thermal comfort is an important parameter. READ MORE

  5. 4. CFD study of the different inlet configurations and airflows in a room with IJV

    University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

    Author : Christos Stiapis; [2022]
    Keywords : Ventilation; CFD; Impinging Jet Ventilation;

    Abstract : A method of providing ventilation using impinging jets (IJV) utilizes stratification while delivering air at a high velocity. As a result of this attribute and the simplicity of its terminal construction, IJV offers an advantage over the well-known Displacement Ventilation (DV) system. READ MORE

  6. 5. Neural Network Based Model Predictive Control of Turbulent Gas-Solid Corner Flow

    University essay from Uppsala universitet/Signaler och system

    Author : Simon Wredh; [2020]
    Keywords : computational fluid dynamics; machine learning; system identification; control theory; multi-phase flow; gas-solid flow; rans; lagrangian particle tracking; neural network; model predictive control; bio-aerosol;

    Abstract : Over the past decades, attention has been brought to the importance of indoor air quality and the serious threat of bio-aerosol contamination towards human health. A novel idea to transport hazardous particles away from sensitive areas is to automatically control bio-aerosol concentrations, by utilising airflows from ventilation systems. READ MORE
