CWA 17954 - Characterization of a hybrid heat pump module. Based on insights from the H2020 project “Industrial Cooling through Hybrid system based on Solar Heat”, this CWA aims to boost solar heat utilization in industrial processes, enhancing energy efficiency. With two-thirds of industrial energy dedicated to heating and cooling, this CWA respon...

The European energy policies are aiming to the electrification of the heating sector as it is considered one of the solutions indicated for the decarbonization of the energy system. Heat pumps represent the most promising and widely adopted solution. However, there are some inherent technological problems to heat pumps, such as evaporator frosting...

Electrification of the heating sector is one of the solutions indicated for the decarbonization of the European energy system and the achievement of the 100% renewable targets for residential and tertiary purposes. Towards this aim, heat pumps represent the most promising and widely adopted solution. The GEOFIT project (H2020-792210) aims to develo...

This workshop brought together a selection of H2020 EU-funded projects involving experts from the biomass, geothermal, solar thermal, and heat pump sectors to discuss a common strategy for increasing the use of renewable energy technologies for heating and cooling for buildings and industry.

HARP, or heating appliances retrofit planning, aims at motivating individuals to plan the replacement of their often outdated and fossil-fuel operated heating appliances with more efficient alternatives. The project, which starts its first heating campaign in winter 2020, expects to reach this goal thanks to the creation of a labelling heating syst...

In this workshop, we discussed the progress of five Horizon 2020 projects—HYCOOL, SHIP2FAIR, THERMOSS, SUNHORIZON and HYBUILD—all implementing solar thermal and renewable technologies for buildings and for the industrial sector. The discussion offered opportunities to identify and benchmark key challenges being faced by the projects, both technical...

In district energy systems planning, the calculation of energy needs is a crucial step in making the investment profitable. Although several computational approaches exist for estimating the thermal energy need of individual buildings, this is challenging at the district level due to the amount of data needed, the diversity of building types, and t...

GEOFIT, “Deployment of novel GEOthermal systems, technologies and tools for energy efficient building retrofitting,” is a recently launched 4-year H2020 project funded by the Innovation and Networks Executive Agency (INEA) under the call topic LCE-17-2017: Easier to install and more efficient geothermal systems for retrofitting buildings. GEOFIT is...

This work deals with the mapping of industrial excess heat recovery through district heating. In this paper a methodology to estimate industrial waste heat recovery in a given territory is presented and applied. The method is particularly suitable for a relatively large, but limited, geographical region, with a significant number of industrial faci...

The EU project SmartReFlex—smart and flexible, 100%-renewable district heating and cooling systems for European cities—aims to promote the massive use of renewable sources for heating and cooling in cities through district heating networks. Among the project activities, the analysis of real case studies shows the potential of renewables in district...

District Heating is acknowledged as an infrastructure which can exploit local heat sources by collecting heat where it is available and transporting it where it is needed. This opens doors to the birth of heat prosumers, a well-known concept in the power sector. The case of Lodi, a 45.000 inhabitants' city 30 km from Milano, offers an exemplary cas...

AIRU, the Italian association of district heating, and the Department of Energy of Politecnico di Milano have tried to evaluate the economic, technical, and urban potential of solar district heating in Italy as an efficient and flexible system to spread the use of solar thermal energy in urban areas. This potential has been estimated with the analy...

In the frame of SmartReFlex project, smart and flexible 100% renewable district heating and cooling systems are promoted thanks to the analysis of local case studies. Italian partners are assessing the feasibility of this kind of projects in the region of Emilia Romagna, supporting local communities willing to go for renewables. In this work, two c...

Within IEA-SHC Task 48 “Quality assurance and support measures for Solar Cooling” the most crucial components of solar thermal cooling plants have been analyzed in detail aiming at improving their quality. Test procedures for characterizing continuous and discontinuous chillers have been developed; market available heat rejection devices have been...

Considering the boundary conditions of Italian district heating and the influence of the electricity market, the Italian association of district heating, AIRU, and the Department of Energy of Politecnico di Milano have evaluated the potential of solar district heating in Italy with the analysis of four case studies of solar thermal integration in e...

After the first solar district heating pilot plants were built over 20 years ago, several operators installed large solar collector areas mainly in Germany and Sweden. This technology is even booming in Denmark, where over 500,000 m2 of solar collectors are currently connected to district heating grids. Italian utilities preferred to wait so far, b...

The present abstract summarizes the main analysis and design steps made for the integration of a solar thermal plant of one thousand square meters into the dyeing process of Benetton industrial facility in Tunisia. The analysis of the actual process load is done by a static model based on assumed energy and water consumptions and the real performan...

The present communication is aimed at presenting both IEA SHC Task 48 methodology and make a status on the ongoing works and first results intermediary results after nearly 2 years of existence.

The present abstract summarizes the main activities and results of a feasibility study campaign for integrating solar thermal collectors in industrial processes in Tunisia. Three technical-economy feasibility studies have been carried out for industrial end users of the textile branch. From the economic point of view, the pay-back time of the inves...
