    Abstract : The use of ground source heat pump systems to provide heating and cooling inbuildings has increased greatly in the last decade or so. These systems have a highpotential for energy efficiency, which has environmental and economicadvantages. READ MORE

  5. 5. Waste heat recovery in a cruise vessel

    University dissertation from Kalmar : Linnaeus Universtity

    Author : Fredrik Ahlgren; Linnéuniversitetet.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; whr; orc; ships; waste heat recovery; energy efficiency; cruise ships; Sjöfartsvetenskap; Maritime Science;

    Abstract : In three studies of a cruise ship the author has investigated waste heat recovery (WHR)from exhaust gases using an organic Rankine cycle (ORC), and also mapped the energyand exergy flows within the ship. Data were collected from the ship’s machinerysystem for a total extent of one year, and this data were used for simulations andenergy calculations. READ MORE
