  1. 1. Solar collector air conditioning system using absorption chiller for a commercial building in Palakkad district, Kerala, India

    Master-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Jerin George; Vysakh Sajeeve Nair; [2023]
    Nyckelord :Renewable Energy; Absorption chiller; Air conditioning; Energy consumption;

    Sammanfattning : Due to effects of global warming and rising living standards, Kerala’s, India air conditioning sector has seen an increase in energy consumption in recent years. Increased need for power resulted in a peak demand owing to the usage of traditional air conditioning systems running on electricity produced from fossil fuels. LÄS MER

  3. 2. Resilient cooling technologies : Simulation study to determine the cooling capacity in old residentialbuildings located in mid-Sweden

    Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Ali Talib Ali; [2022]
    Nyckelord :cooling; cooling demand; absorption chiller; absorption refrigeration; district cooling; primary energy; resilience; residential buildings; old buildings; cooling capacity.;

    Sammanfattning : The Long-term changes in the climate conditions have increased the need foradequate thermal comfort systems. These alternations influence extremeevents, which their intensity and frequency have increased over the past years.Moreover, this study focuses on space cooling and parameters that the systemshould have to be considered as resilient.

  4. 3. CHILLER DIAGNOSTICS Machine learning approach Carrier

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Vilius Koegst; Tatiana Orlova; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Chillers are large and complex machines that are used for temperature regulation in large buildings and plants. An undetected fault in the machine can lead to extended downtime and cause both great financial losses and increased environmental impact. LÄS MER

  5. 4. Solar cooling systems : A comparative analysis for solar thermal and solar PV cooling systems for Industries using a techno-economic approach

    Master-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Christoffer Larsson; [2022]
    Nyckelord :Photovoltaic cooling; solar thermal cooling; global LCOC;

    Sammanfattning : With the need to reduce CO2 emissions in the energy sector, ensure electric grid stability and reduce future cost uncertainties for process cooling, solar cooling can be an interesting solution. This report describes the comparison of solar cooling with either a photovoltaics system or a solar thermal system using a thermally driven chiller. LÄS MER

  7. 5. 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
