1. 1. Demand Controlled Ventilation (DCV) Systems in Commercial Buildings. Functional Requirements on Systems and Components

   Författare :Mari-Liis Maripuu; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DCV; CO2-sensors; indoor climate control; energy efficiency; CAV; mixedgas;

   Sammanfattning : Demand controlled ventilation (DCV) is considered as an energy efficient solution forair-based cooling and indoor air quality control. Considerable energy savings can beachieved when the airflow rate is continuously adapted to the actual load condition. LÄS MER

3. 2. Behovsstyrd ventilation i lokalbyggnader-Innebörd och strömningstekniska konsekvenser

   Författare :Andreas Karlsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; duct systems; energy efficiency flow mechanics; DCV; energy; pressure; ventilation; control-on-demand; demand controlled ventilation;

   Sammanfattning : In todays society energy efficiency and energy savings are becoming increasingly important. The building sector represents a major part of Swedens total use of energy. Furthermore, ventilation constitutes the single largest factor in the energy balance of buildings. LÄS MER

4. 3. Modelling and Intelligent Climate Control of Buildings

   Författare :Mohsen Soleimani Mohseni; Bertil Thomas; Lennart Jagemar; Geoffrey Levermore; Chalmers University of technology; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neural networks; indoor climate control; operative temperature; demand controlled ventilation; prediction; feed-forward control;

   Sammanfattning : The main purpose of the work presented in this thesis is to examine the possibilities of different control techniques together with intelligent building technology to improve the indoor climate and/or the energy efficiency of buildings. In particular, the possibilities of measuring more variables and using them as input to the controllers are examined. LÄS MER

5. 4. Ventilation System Design - A Fluid Dynamical Study with Focus on Demand Control

   Författare :Andreas Karlsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; variable airflows; pressure level; ventilation system design; HVAC design; variable air volume; pressure loss; VAV; demand control ventilation;

   Sammanfattning : Ventilation corresponds to a large part of the total energy use of a building and a lot of attention has been paid to how to reduce this energy use. However, much of this work on saving energy has been focused on reduction of the airflows and how this in turn reduces the energy use. LÄS MER

7. 5. Pluripotent Dynamic Capabilities in the Internationalization of Firms : Focus on Learning, Innovating and Networking in SMEs from Sweden
