In this paper, an experimental study regarding the natural circulation in connected vertical rectangular loops is presented. Typically, the geometry of the natural circulation loops (NCL) is rectangular or toroidal and the analysis is focused on the thermo-hydraulic behaviour of a single working loop. In this study, a new approach referred to...

The present investigation addresses the issue of thermal insulation of building walls. In particular, the case of a wall subjected to Mediterranean climatic conditions, typical for the city of Genoa (Italy), is taken into account. A comparison between a polyurethane and a PCM layer with a thickness of 4 cm is proposed. The analysis is developed...

Magnetic refrigeration is becoming increasingly relevant as a means to achieve sustainability in refrigeration, thanks to its durability, efficiency, and low environmental impact. This paper regards the design of a new rotary magnetic refrigerator feasible for domestic use at room temperature. An interdisciplinary approach was necessary to...

The plant in the Sport Palace "Carmine Romanzi" (Palacus, University of Genoa) consists of a Solar Assisted Heat Pump (SAHP) which integrates the two existing gas burners in the production of Domestic Hot Water (DHW) and Space Heating (SH). To manage the large number of control and measurement points along the installation, a data acquisition...

The issue of transmittance of thermal bridges in existing buildings has been addressed aiming to achieve correlations able to evaluate the ground-contact thermal bridges. A bi-dimensional steady state FEM model has been implemented to simulate wall-to-floor structural node and then validated in accordance with the EN ISO 10211:2017 standard....
