1. 16. Techno-economic evaluation of heat-driven cooling solutions for utilization of district heat in Aalesund, Norway

   Master-uppsats, KTH/Energiteknik

   Författare :Bjørnar Vattøy; [2018]
   Nyckelord :;

   Sammanfattning : This study is aimed to evaluate the techno-economic feasibility of implementing heat driven cooling technologies in buildings connected to Tafjord Kraftvarme’s district heating network in Aalesund, Norway. Heating and cooling demands were found by projecting two 4000 𝑚2 office buildings according to Passive House and Low Energy Building criteria, within the frame of the energy requirements in the TEK17 building regulations (Standard Norge, 2012) (Norwegian Building Authority, 2017).

3. 17. Performance evaluation in post integrated organic Rankine cycle systems : A study on operational systems utilizing low grade heat

   Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

   Författare :Jakob Lindqvist; Niklas Faber; [2018]
   Nyckelord :ORC; organic Rankine cycle; small scale; low grade heat; experimental; micro scale; CHP; combined heat and power; renewable energy; WHR; waste heat recovery; steady-state detection; cogeneration; performance evaluation; Coolprop;

   Sammanfattning : Organic Rankine cycles can be integrated with district heating systems and in applications of biogas digestion. Evaluating the performance of the installations by Againity AB in Ronneby and Norrköping, Sweden, is a unique opportunity which can support the establishment of ORC technology in the waste heat recovery market, unveiling its feasibilities and limitations.

4. 18. Perspectives for mini-scale ORCpower plants coupled with internal combustion engines in the European Union

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

   Författare :Tamás Pál; [2017]
   Nyckelord :;

   Sammanfattning : The ideal energy production and delivery system is featured by less transmission network, smarter grid and higher proportion of locally dispersed renewables in cooperation with combined heat and power (CHP) plants and energy storage. The Organic Rankine Cycle (ORC) technology can play a compelling role in achieving the listed objectives. LÄS MER

5. 19. Energiutvinning ur magasinerat spillvatten

   Kandidat-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

   Författare :Magnus Axelsson; [2017]
   Nyckelord :;

   Sammanfattning : The houses we build today are very energy efficient and we have minimized the demand of energy for heating. But tap water can still consume 50% of the total energy cost. Mandatory laws and regulations of today forces us to look over our usage of energy. LÄS MER

7. 20. New technique for energy efficient CO2-separation through absorption with a sterically hindered amine

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Anton Johansson; [2016]
   Nyckelord :Experimental Setup; AMP carbamate; NMP; AMP; Absorption; Sterically hindered amine; proof-of-concept; chemical engineering; kemiteknik; Technology and Engineering;

   Sammanfattning : The degree project described in this report also acts as a deliverable for a research project. The research project focuses on a new technique for the upgrading of biogas. This new technology uses a sterically hindered amine to absorb carbon dioxide from the biogas to raise its energy value. LÄS MER
