  2. 1. Environmental Assessment of Air-conditioning Systems in Offices. Some Aspects Related to Design

    Author : Katarina Heikkilä; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; air-conditioning; office buildings; environmental assessment; flexibility; weighting methods; comfort cooling system; energy efficiency; environmental performance; HVAC systems; life cycle assessment;

    Abstract : The primary function of an air-conditioning system, i.e. to fulfil given requirements on indoor climate in a specific building, can generally be achieved by several system designs. The systems may have varying environmental performance. READ MORE

  4. 2. Modelling the dynamics of domestic low-temperature heat pump heating systems for improved performance and thermal comfort : a systems approach

    Author : Dimitra Sakellari; Per Lundqvist; Savvas Tassou; KTH; []
    Keywords : Technology; heat pump; domestic heating and ventilation; low-temperature hydronic heat distribution; systems approach; integration; simulation; energy efficiency; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The present environmental concerns and the rising human requirement for solutions with better comfort and lower costs have resulted in an increased awareness for the energy use in the built environment. Technical advances in building structural systems and materials, heating and other comfort-providing systems and controlling strategies all lead to the integration of building technology with the function of buildings and the aesthetics.

  5. 3. Machine Learning Concepts for Service Data Interoperability

    Author : Jacob Nilsson; Fredrik Sandin; Jerker Delsing; Marcus Liwicki; Tapio Heikkilä; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; system of systems; system of cyber-physical systems; subsymbolic representations; semantic interoperability; dynamic interoperability; Cyber-Physical Systems; Cyberfysiska system;

    Abstract : Industrial automation is transforming by ongoing digitalization efforts to create a flexible industrial internet of things, turning manufacturing facilities into large-scale systems of cyber-physical systems. This development requires addressing the challenging issue of making heterogeneous systems, data models, and standards interoperable, a core problem in designing sustainable service-oriented automation frameworks.

  6. 4. Evaporative and Desiccant Cooling Techniques Feasibility When Applied to Air Conditioning

    Author : Torbjörn Lindholm; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; desiccant wheel; desiccant cooling; evaporative cooling; dehumidification; air-conditioning; HVAC; comfort;

    Abstract : This thesis describes evaporative and desiccant cooling processes for air-conditioning purposes, i.e. for the removal of surplus heat from premises by the supply of cooled ventilation air. These cooling processes can replace the conventional method of cooling ventilation air involving the use of refrigerating machinery. READ MORE

  7. 5. Environmental Assessment of Air-conditioning Systems. Design Considerations for Swedish Conditions

    Author : Katarina Heikkilä; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; environmental assessment; life cycle assessment LCA ; weighting;

    Abstract : There is an increased awareness about global environmental changes, and a need forproducts and systems with the lowest possible impacts on the environment, withouttrade-offs on the original function or quality. The need for air-conditioning andcomfort cooling in commercial buildings has increased and an appropriate design ofthe air-conditioning system is thus important in order to reduce the environmentalimpact related to air-conditioning of buildings.
