  1. 11. Analysis of energy efficient heat and lighting systems in a subarctic greenhouse

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :William Sigvardsson; [2023]
    Nyckelord :Energy efficiency; Sub-arctic greenhouses; Energy measures; Greenhouse climate control; Greenhouse technology; CFD;

    Sammanfattning : This report studies a subarctic greenhouse located in Nikkala, Sweden called Nikkala handelsträdgård. Through a visit to the greenhouse coupled with the creation of two simulation models this study investigates the differences in energy demand with water-carried and air-carried heating systems, high pressure sodium lights and Light emitting diode lights and insulation in parts of the greenhouse without a active cultivation.

    Sammanfattning : Due to the growing population and climate change, the world will see an increase in demand for food, freshwater and renewable energy supply. Agrivoltaics has the possibility to address all these problems, by producing food and renewable energy but also by reducing water usage in agriculture. LÄS MER

  5. 14. Water born cooling of closed greenhouses : An enclosed vertical water curtain cooling system

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

    Författare :Ahmad Kamal; [2022]
    Nyckelord :Greenhouses; Water born cooling; Enclosed water curtain; radiative cooling; Surplus heat energy;

    Sammanfattning : The greenhouses play a key role in food sustainable production, the purpose of the greenhouses is to make an artificial suitable environment to grow different kinds of plants. The cost of energy used in the greenhouses to ensure the optimum temperature, humidity, and CO2 concentration, makes up a large part of the final cost of food. LÄS MER
