Hierarchizing Energy Saving Strategies in Wine Industry by Advanced Modelling of Chilling Units Operation
2019
Wineries are energy intensive industries and in order to make the production process more sustainable, solutions for an efficient use of energy should be implemented. Large surveys conducted in the wineries sector have highlighted the importance of performing accurate energy audits and have identified in the installation of efficient cooling/refrigeration systems the most promising solutions in a variety of cases. Unfortunately, the savings achieved by such energy efficient solutions is often calculated by highly simplified approaches, which do not take into consideration the actual operating conditions of the equipment (highly variable on a seasonal and daily basis). In this paper a system…
Sistema di irrigazione a perno centrale
2021
L’invenzione consiste nell’impiego, nell’irrigazione pivot, dei comuni irrigatori rotanti che si utilizzano nei sistemi di irrigazione a pioggia (o per aspersione), che hanno il vantaggio, rispetto agli spruzzatori ed ai gocciolatori, di essere dotati di un ugello terminale di elevato diametro (4-30 mm). L’idea nasce quindi dalla ricerca di un sistema irriguo che conservi i benefici dell’irrigazione pivot (completa automatizzazione, manodopera limitata alla manutenzione degli apparecchi erogatori, elevata efficienza) e che al contempo rimuova del tutto il problema dell’occlusione degli apparecchi erogatori. Vengono così azzerati i costi di manodopera e, soprattutto, viene consentito l’impie…
LA CASA EOLIANA: UN SISTEMA DI RAFFRESCAMENTO PASSIVO
2012
The Aeolian archipelago is a microcosm of traditional buildings that have retained their original character and form constructive. The special traditional technologies used and the climatic conditions of the site were also used for the application of a solution used in traditional passive systems with the aim of contributing to energy savings through the application of a particular covering of chestnut wood.
"Thermal penalty factors" accounting for site topological characteristics in pinch design of Heat Exchanger Networks
2010
Pinch analysis allows to determine targets and solutions for minimum energy requirements in process plants, basing on innovative tools like composite curves and table problem formulation, which ultimately allow generating an optimized heat exchanger network design. On another hand, this technique does not account directly for a number of factors which could play a primary role for the practical feasibility of the network. What if, for instance, once identified an optimal lay-out, we realize that some matches are hardly feasible in practice? Could we adapt the conventional pinch approach to keep into account site topological features since the preliminary design phase? In this paper the auth…
Opportunistic Synchronization for Improving IEEE 802.15.4 MAC Performance in Chain Topologies
2010
The most effective solution for energy saving in low-rate wireless sensor networks is maintaining each node in a doze state as long as possible. In order to guarantee network connectivity, the intervals at which the network sensors are turned on and off have to be coordinated. Therefore, synchronization is a very critical function for sensor networks. In this paper, we analyze the IEEE 802.15.4 MAC performance in sensor networks deployed in a chain topology. For this topology, critical inefficiencies can arise in case of multi-hop packet deliveries. We evaluate the impact of different synchronization schemes on the network performance, both in terms of network throughput and in terms of ene…
Innovative technologies for temporary architecture
2009
Problem risen from temporariness and flexibility concepts of built concern, always constituted, all over technological advanced countries and throughout the whole history of scientific research, some of the most interesting aspects of technologies, industry and industrialization processes. Several project proposals about really light structures easily gatherable, transportable, that can be dismantled and reconverted, are proves of that such as their use in order to obtain flexible and functional living solutions. They are systems adaptable to different needs and fit to offer a concrete solution for the necessities related to the new ways of living. In fact temporary buildings that were thou…
