[1]Department of Engineering, University of Ferrara, Este, Italy
[2]Department of Architecture, University of Ferrara, Este, Italy
[3]Faculty of Engineering, University of Nottingham, Nottingham, UK

In ground-coupled heat pumps (GCHPs) the coupling between heat pumps and ground occurs by means of ground heat exchangers, that can be installed vertically inside boreholes (BHEs) or horizontally (HGHEs). In the horizontal installation, the heat exchangers are placed in shallow trenches ... Read More

Numerical Analysis of the Thermal Resistance of a Multi-Layer Reflective Insulation Material Enclosed by Cavities under Varied Angles

R.S. Pelzers[1], A.W.M. van Schijndel[2]
[1]Former student Building Physics, Department of the Built Environment, Eindhoven University of Technology, Eindhoven, The Netherlands
[2]Chair Building Physics, Department of the Built Environment, Eindhoven University of Technology, Eindhoven, The Netherlands

A numerical analysis on the thermal performance of a sample, consisting of two cavities surrounding a Multi-Layer Reflective Insulation (MLRI) material, under various angles and for downward and upward heat flows was performed. The sample reached high thermal resistance values when ... Read More

Development of a Thermo-Hydro-Geochemical Model for Low-Temperature Geoexchange Applications

F. Eppner [1], P. Pasquier [1], P. Baudron [1],
[1] École Polytechnique de Montréal, Montréal, QC, Canada

Standing column wells (SCW) are open-loop geoexchange systems used to provide space heating and cooling to buildings. As they use groundwater as heat carrier fluid and modify its thermo-chemical conditions along the year, they may favor calcite dissolution and precipitation, thus ... Read More

Thermal Performance of the New Bioclimatic Hall of the Historical Hospital in Florence

C. Balocco, and E. Marmonti
Dipartimento di Energetica “Sergio Stecco”
Università degli Studi di Firenze
Firenze, Italy

The main aim of the present work is the study of the thermal and energy performances of the new hall of the Old St.Maria Nuova Hospital in the center of Florence (Italy). Transient simulations were carried out of the 3D model of the hall to analyse the air flow patterns, distribution and ... Read More

Enhanced Transient Modeling of Hybrid Photovoltaic Air (PVT) Module

R. Kiflemariam[1], M. Almaz[1], F. Zevallos[1], C. Lin[1]
[1]Department of Mechanical & Materials Engineering, Florida International University, Miami, FL, USA

A 2D transient heat conduction model was created in COMSOL Multiphysics® software to study the performance of photovoltaic-thermal (PVT) water system. The model captures the variation of important environmental and system parameters such as outside temperature, solar irradiation, air ... Read More
