  2. 1. 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

  4. 2. Energy Efficiency in Shopping Malls : Some Aspects Based on a Case Study

    Author : Sofia Stensson; Jan-Olof Dalenbäck; Per Fahlén; Monica Axell; Jeffrey Spitler; Sweden Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shopping mall; energy use; energy efficiency; HVAC system; load patterns; case study; regulatory requirements; building code; and energy declarations;

    Abstract : The building sector accounts for approximately 40 percent of our energy use. To reach existing environmental targets energy use will have to be reduced in all building types. At the European level, the main legislative instrument for improving the energy efficiency of the building stock is the Energy Performance of Buildings Directive (EPBD). READ MORE

  5. 3. Design of Energy Efficient Buildings. Applied on HVAC Systems in Commercial Buildings

    Author : Lennart Jagemar; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; design; simulations; economic analysis; energy efficiency; commercial;

    Abstract : A methodology for planning and design of energy efficient buildings is presented and analysed. The starting point is the definition that energy efficiency is a question of minimizing the energy end-use within realistic economic frames and fully preserved function. The methodology is based on a systematic approach to the issue of energy efficiency. READ MORE

  6. 4. Numerical modeling of the coupled feedback between pool fires and their environment

    Author : Jonathan Wahlqvist; Avdelningen för Brandteknik; []
    Keywords : ;

    Abstract : Computational fluid dynamics (CFD) is often used within performance based fire safety engineering and its use has increased as available computational power has increased. However, there is still a need to improve CFD modeling to push it beyond its current usage limitations. READ MORE

  7. 5. Experiment Design for Closed-loop System Identification with Applications in Model Predictive Control and Occupancy Estimation

    Author : Afrooz Ebadat; Bo Wahlberg; Håkan Hjalmarsson; Erik Ydstie; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experiment design; System identification; Model Predictive Control; Building automation; Occupancy estimation; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The objective of this thesis is to develop algorithms for application-oriented input design. This procedure takes the model application into account when designing experiments for system identification.This thesis is divided into two parts. READ MORE
