1. 1. Thermal Investigation of the Green Revolution Energy Converter : A study on the heat transfer within the GREC in regards of temperature distribution and heat rate

   L3-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

   Författare :Wilma Fager; Maja Abrahamsson Bolstad; Emma Gustafsson; Emma Andersson; Matilda Eriksson; [2023]
   Nyckelord :GREC; Energy; Heat transfer; Heat rate; Temperature distribution;

   Sammanfattning : To reduce emissions, new technological solutions can be of use. One technology which is currently being developed is the Green Revolution Energy Converter, GREC. GREC is an engine with the aim to produce electricity from temperature gradients.  This project is part of a greater project that is divided in two with different focus areas. LÄS MER

3. 2. Techno-economic analysis of power‑to‑heat‑to‑power storage for a residential building

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

   Författare :Alicia López de Ceballos Regife; [2021]
   Nyckelord :Solar energy; storage; PV installation; Li‑ion; residential sector; latent heat; high temperature; hot water tank; hybrid PV; heat pump; self-consumption; CHP; optimization; Nedler and Mead.;

   Sammanfattning : Despite the share of renewable energies worldwide is increasing, which can help in reducing the CO2 emissions, their unpredictability has become a problem due to the mismatch between generation and demand. Among the different alternatives to solve this problem, energy storage is a very interesting solution. LÄS MER

4. 3. Improving the Efficiency of Thermal Energy Usage in Residential Buildings by Heat Recovery from Wastewater

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

   Författare :Pranjal Jain; Khaled Alturkmani; [2021]
   Nyckelord :Wastewater; Heat Exchangers; Heat Pumps; Biofilms;

   Sammanfattning : This study aims to rationalize the consumption of thermal energy in residential buildings by recovering heat from wastewater inside the building before entering the central sewage network outside the building, by conducting an analytical study for a residential tower in Syria to find out the coverage percentage of the heat energy recovered from wastewater for the heating and domestic hot water loads needed for the tower, and calculating the percentage of reduction in carbon dioxide (CO2) gases. It is a simple technology as the thermal recovery system consists of three main components, which are in order: a wastewater tank, heat exchangers, and a heat pump. LÄS MER

5. 4. Aqua Ammonia as Secondary Fluid in Ice Rink Applications

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

   Författare :Brianna Kilberg; [2020]
   Nyckelord :Ice rink; secondary fluid; aqua ammonia; ammonia water; thermophysical properties; corrosion; pressure drop; pumping power; refrigeration;

   Sammanfattning : Refrigerant management is crucial in the attempts to slow climate change. Emissions from the refrigeration sector are primarily due to poor management and unsafe destruction of refrigerants currently in circulation. Safe refrigerant management and improving system operating efficiency can result in a reduction of emissions. LÄS MER

7. 5. Alternative energy supply study for a cottage in Vifors

   Magister-uppsats, Högskolan i Gävle/Energisystem

   Författare :Mikel Lumbier Fernandez; [2018]
   Nyckelord :Building heating demand; IDA ICE; Solar thermal collectors; Heat pump; Combi systems;

   Sammanfattning : The present master thesis was done during the spring of 2018. A cottage located in Vifors is studied with regard to its heating requirements. At the time of the study, the house could not be inhabited the whole year because there was no tap hot water available and the space heating demand was covered by electricity. LÄS MER
