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

    Author : Torbjörn Lindholm; Chalmers University of Technology; []
    Keywords : 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

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

    Author : Katarina Heikkilä; Chalmers University of Technology; []
    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

  3. 3. On Future Electricity Use : Air Conditioning and Electrothermal Processes

    Author : Tomas Ekwall; []

  4. 4. Automotive Climate Systems - Investigation of Current Energy Use and Future Energy Saving Measures

    Author : Filip Nielsen; Chalmers University of Technology; []
    Keywords : simulation and modeling; HVAC; energy efficiency; testing; thermal management; passenger compartment; automotive; Air conditioning; energy consumption; fuel consumption;

    Abstract : Automotive climate systems use energy to achieve thermal comfort for the vehicle passengers. This energy use affects vehicle fuel consumption. The objectives of this thesis are to understand the energy use of automotive climate systems and investigate the effect of different energy saving measures.The research was conducted in several steps.

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

    Author : Katarina Heikkilä; Chalmers University of Technology; []
    Keywords : 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.
