This thesis includes the testing of different refrigerants in order to calculate coefficients of performance of different refrigerants. This project involves the detailed study of actual and theoretical coefficients of performance of six... more
Der Kachelofen mit seinen attraktiv gestalteten Ofenkacheln ist für die Erforschung spätmittelalterlicher und neuzeitlicher Wohnkultur in Mitteleuropa von grosser Bedeutung. Die vorliegende Publikation behandelt sowohl den Kachelofen als... more
The change of weather conditions and occupancy schedules makes heating ventilating and air-conditioning (HVAC) systems heavily dynamic. The mass and thermal inertia, nonlinear characteristics and interactions in HVAC systems make the... more
These are the first version of my presentation for the course advanced heat transfer (Transferencia de Calor Avanzada)
Single zone (SZ) air handling units (AHUs) are widely applied in the conditioned spaces. A SZ AHU typically consists of a chilled water cooling coil, a hot water heating coil, and a supply fan. For a constant volume (CV) SZ AHU or... more

Today, energy crisis turn out to be a serious threat towards sustainability for developing countries since their energy demand is growing more rapidly than developed countries. On the other hand, fossil fuels cannot sustain anymore in the... more
In this paper, a purposely designed code for the performance analysis of the Water Loop Heat Pump (WLHP) systems is presented. Hourly, daily and seasonal energy system consumptions, operating economic costs and environmental impact... more
La UNI-EN 15759-1: 2011 richiede il rispetto del clima storico, come imposto dalla UNI-EN 15757: 2010 “Conservazione dei beni culturali - Specifiche concernenti la temperatura e l’umidità relativa per limitare i danni meccanici causati... more
This study represents an experimental and numerical investigation of the enhanced prototypes of the induction air heaters. For this purpose, flow field is enhanced in order to avoid turbulence. The air mass flow rate, outlet construction... more
In this paper, a novel purposely designed dynamic simulation model for the performance analysis of solar heating and cooling systems is presented. The investigated system layouts are based on single stage LiBr–H2O absorption chillers and... more
In certain parts of the country and the globe, a consistent and steady supply of power is still scarce and inaccessible. In such places, this work will support refrigeration of nourishments, food, medications, etc... The results of such... more
Adequate and consistent energy supply is often regarded as a major factor in the development of any country. To add to this, the depletion of fossil fuels has also emphasised the need for alternate renewable energy solutions to meet... more
Global warming, ozone layer destruction, and limited energy resource enforce us to find alternative refrigeration system can operate with low heat thermal source so that it can be powered by solar energy or lower temperature waste heat.... more
Green façades are becoming an important architectural element in an urban environment. Regarding the technology of the installation of green façades, one can distinguish between direct and indirect green façades, living walls and double... more
Improving the sustainability and performance of existing housing stock is a significant challenge. Agencies and organisations have promoted various policies and programmes to address these matters including retrofitting insulation and the... more
