5. 3. Optimization of ground-coupled systems for heating and cooling of buildings

   Author : Jüri Naumov; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; free-cooling; brine temperature; heat pump; ground system; heating demand; storage; building load; cooling demand; Borehole;

   Abstract : The use of ground-coupled systems in commercial buildings offers economic as well as environmental advantages. When both heating and cooling is required, a ground-coupled system can function both as a heat source and a heat sink. At the same time, it can also serve as a short term as well as a seasonal storage. READ MORE

7. 5. Direct-Ground Cooling Systems for Office Buildings: Design and Control Considerations

   Author : Taha Arghand; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Borehole; Cooling capacity; Laboratory experiments; Ground heat exchanger; Fluid temperature levels; Control; Direct-ground cooling; Optimization; High temperature cooling;

   Abstract : Direct-ground cooling systems are defined as systems in which the ground is used as the only source for cooling mainly in commercial buildings. These systems benefit from exchanging heat with the ground, of which its temperature is basically constant below a certain depth year around. READ MORE
