  1. 1. Thermal system analysis of embedded building integrated heating - Numerical model and validation of hydronic floor heating systems

    Författare :Henrik Karlsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; radiant heating; floor heating; low temperature hydronic heating; whole building thermal system analysis; Simulink modelling; Building integrated heating;

    Sammanfattning : A numerical simulation tool for building integrated heating (BIH) systems is developed. BIH is defined as a heat supply system that maintains the indoor thermal comfort within acceptable limits by means of a controlled heat supply to the inner of the building envelope/structure.

    Författare :Henrikki Pieskä; Johan Silfwerbrand; Adnan Ploskic; Qian Wang; Sture Holmberg; Sasan Sadrizadeh; Ambrose Dodoo; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Radiant cooling; Geothermal cooling; Energy efficiency; Thermal comfort; Sustainable development; Strålningskylsystem; Geotermisk kyla; Energieffektivitet; Termisk komfort; Hållbar utväckling; Strömnings- och klimatteori; Fluid and Climate Theory;

    Sammanfattning : Sustainable development is increasing its significance in both the scientific and political agenda. In light of this development, the United Nations have published 17 Sustainable development goals (SDGs). LÄS MER

  4. 3. Thermodynamic aspects and heat transfer characteristics of HiTAC furnaces with regenerators

    Författare :Nabil Rafidi; Wlodzimierz Blasiak; John Witton; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion; flameless; oxy-fuel; heat-recirculation; gas-recirculation; heat transfer; furnace; radiant-tube; regenerative burner; honeycomb; fixed-bed; Thermal energy engineering; Termisk energiteknik;

    Sammanfattning : Oxygen-diluted Combustion (OdC) technology has evolved from the concept of Excess Enthalpy Combustion and is characterized by reactants of low oxygen concentration and high temperature. Recent advances in this technology have demonstrated significant energy savings, high and uniform thermal field, low pollution, and the possibility for downsizing the equipment for a range of furnace applications.

  5. 4. Revisiting the urban block in the light of climate change : A case study of Budapest

    Författare :Csilla V Gál; Peter Land; []
    Nyckelord :HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Since the beginning of the twentieth century, the urban block configuration of free-standing buildings has been deemed superior to other built forms, as it provided the necessities of modern healthy living: sunlight and fresh air. In light of climate change, the dissertation aims to reevaluate these long held beliefs and to reintroduce microclimate as an urban design consideration. LÄS MER

  7. 5. A multi-scale approach for predicting the fire response of building barriers

    Författare :Blanca Andrés Valiente; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fire; Building Barriers; Heat transfer; Experimental; Gypsum; Stone wool; furnace; H-TRIS;

    Sammanfattning : Building barriers are compartmentation elements in buildings that limit the passage of fire and smoke to adjacent spaces. They are key elements in the overall response of a building in a fire. The adequate fire response of building barriers is usually assessed by the fulfilment of standardized resistance to fire tests.
