  1. 1. Improving Cooling Tower Water and Energy Efficiencies based on a New Analytical Method

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Rayan Abboud; [2022]
    Nyckelord :;

    Sammanfattning : Cooling towers are largely used in many industrial processes for cooling purposes. The basic concept of a cooling tower includes cooling down water by means of evaporation, thus giving it the terminology “evaporative cooling”. Air mixes with water in a cooling tower and is ejected carrying the heat that is transferred from the water. LÄS MER

  3. 2. Considerations and Development of a Ventilation on Demand System in Konsuln Mine

    Master-uppsats, Luleå tekniska universitet/Geoteknologi

    Författare :Seth Gyamfi; [2020]
    Nyckelord :Ventilation on demand VOD ; Swedish Occupational Health Safety OH S regulations; Threshold Limit Value TLV ; Ventilation model; Diesel; battery-powered; heat; and blast simulations; Contaminants;

    Sammanfattning : Ventilation on demand (VOD) concept has earned significant worldwide attention by several mining companies in recent years. It is a concept where airflow is provided only to areas that require ventilation. The implementation of the concept has resulted in significant savings in annual energy consumption and cost for several companies globally. LÄS MER

  4. 3. An experimental study on an evaporative cooler for hot rural areas

    Kandidat-uppsats, KTH/Energiteknik

    Författare :Katarina Gustafsson; Hanna Simson; [2016]
    Nyckelord :;

    Sammanfattning : In developing countries about 40 % of the food-waste is due to post-harvest losses, such as improper storage. The Zeer-pot is an evaporative cooler, which cools the inside by convective heat transfer, and can be used to keep fruits and vegetables fresh longer. LÄS MER

  5. 4. Energikartläggning av ett mjukpappersbruk : Värmeåtervinning som alternativ till ånga för uppvärmning av lokaler

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Viktor Eriksson; [2016]
    Nyckelord :Mjukpapper; energianvändning; värmeväxlare;

    Sammanfattning : Massa- och pappersindustrin i Sverige stod för 51 % av den svenska industrisektorns totala energianvändning år 2015. Det gör det extra viktigt för svenska massa- och pappersbruk att dokumentera sin energianvändning med jämna mellanrum för att identifiera var och hur energin används, en så kallad energikartläggning.

  7. 5. Modeling & Simulation of a Cooling Tower with COMSOL Multiphysics

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Matilda Lundberg; [2015]
    Nyckelord :kemiteknik; chemical engineering; model; cooling tower; Technology and Engineering;

    Sammanfattning : The aim of this project is to create a model of a Cooling Tower setup using COMSOL Multiphysics. Experiments are performed on the setup in order to provide data of the behaviour. The model is fitted to the data by estimate the models parameters. The parameter estimation is performed with MATLAB by connecting the programs using LiveLink, COMSOL 5. LÄS MER
