Report from Italian National Workshop - Heating & Cooling in Italy with Heat Pumps towards 2030

On November 11, in conjunction with the Executive Committee meeting of HPT TCP by IEA, the Italian National Team hosted an exciting online workshop focusing on the most recent developments in market, policy, and research. More than 40 people from the 17 member countries around the world attended the workshop.

The workshop started with brief introductions from the host Maurizio Pieve, ENEA, delegate for Italy in the TCP Exco, and Giorgio Graditi, Director of the Department of Energy. Maurizio emphasized the relevance of the national workshop, stating that it is an opportunity to take a deeper look at heating and cooling in Italy utilizing heat pumps in order to decarbonize the building stock. Giorgio spoke about ENEA, a public body aimed at research, technological innovation, and the provision of advanced services to enterprises, public administration, and citizens in the sectors of energy, the environment, and sustainable economic development.

Mr. Federico Musazzi, Secretary-General of Assoclima, the Italian Association of Heating, Cooling, and Ventilation System Manufacturers, gave the following presentation. He spoke about how the European Commission has begun an internal review of Directive 2018/2001 on the promotion of the use of renewable energy sources, with the goal of ensuring that RES contribute cost-effectively and sustainably to at least a 55% reduction in GHG emissions by 2030, in line with the Climate Target Plan, with a 38% to 40% share in 2030. His presentation emphasized the need of boosting renewable energy in buildings as a cornerstone to achieving climate neutrality by 2050, as buildings account for 40% of total energy consumption in Europe. Highly efficient, smart, and renewable-based appliances play a critical role in reducing building energy use while also lowering CO2 emissions. Click here to read more >

According to Roberto Nidasio of the Comitato Termotecnico Italiano (CTI), heat pumps “certainly play a vital role in the energy efficiency of buildings”. Heat pumps in the context of building energy performance were the title of his talk. Roberto spoke about the need to accurately assess heat pumps’ energy performance, not only for their energy classification or labeling but also for their use inside the building. As a result, it’s critical to analyze the installation’s specific setting. Technical standards attempt to achieve this in the most efficient manner feasible. According to Roberto, there are essentially two sorts of standards for heat pump energy performance: product standards and system standards. Click here to read more >

Marco Buoni, President of the Air Conditioning and Refrigeration European Association, gave the following presentation, which focused on the importance of the servicing industry in heating and cooling (AREA). Mr. Buoni emphasized the importance of heat pumps, heating, and cooling in Italy’s and Europe’s decarbonization plans, respectively. The demand for refrigeration, air conditioning, and heat pumps is growing. The industry consumes 20 to 25% of total electricity, and several legislations have been passed to improve energy efficiency, improve maintenance and installation, and avoid refrigerant leaks.

Sergio Bobbo of the CNR-ITC discussed what the Italian participants work with within the IEA-HPT Annex 54 under the heading of the Italian team’s experience. In the lab, they measure a variety of thermophysical parameters, focusing on HFOs. He presented some of the findings from GEO4CIVHIC–Horizon2020, an EU project he was involved in. The project’s main goal was to find the best replacements for R134a and R410A in geothermal heat pumps. He presented preliminary results of the refrigerants studied as well as operating conditions. Their findings show that in high-pressure refrigerants, R454B is the most promising substitute for R410A in all cycles studied. Similarly, their research reveals that in low-pressure refrigerants, R516A is the MOST EFFICIENT refrigerant (COP + 10% over R134a). Click here to read more >

In his presentation, Innovation for Sustainable Heating: A New Generation of High Temperature, Ferdinando Pozzani of TEON offered a brief history of the company, which develops, manufactures, and markets novel solutions for the heating and cooling of buildings and, more generally, large volumes. He explained that several years of applied research at Trieste’s Science Area Park led to the industrialization of a family of patented solutions in the environmental and energy domain, which were awarded the Smart Future Mind Award in 2011 because they produce no emissions into the atmosphere, paving the way for a healthier city.

ENEA’s Luca Gugliermetti gave the final presentation, which focused on their research work on the Solair-HP project, which involved the development and testing of a novel solar-assisted trans-critical CO2 heat pump. It was created with the goal of lowering electrical usage through the use of a solar thermal source. It even has a patented photovoltaic hybrid solar panel connected with a tube heat exchanger that may be utilized as an auxiliary heat source during the winter. According to Luca, using this technique eliminates the need for an air finned coils exchanger, reducing difficulties such as ice development on the fins (frosting) and energy expenditure owing to the finned coil’s fan. Furthermore, the usage of CO2, which has a low GWP (Global Warming Potential), along with the ability to generate power using PVT (PhotoVoltaic and Thermal), makes this solution very eco-friendly, with a minimal environmental impact and the ability to completely utilize renewable energy from the sun.
