On 22 – 23 October 2019, the heat pump world met in Nuremberg, Germany. International experts, even from outside Europe, attended to discuss the European heat pump market, technology and application trends. Product and organization presentations at the Foyer-Expo supplemented the variety of information provided by the speakers.
EPEE – The number of heat pumps must triple until 2030
Andrea Voight from EPEE gave the first presentation during the summit, referring to the IEA sustainable scenario that the number of heat pumps must triple until 2030. She also talked about that cooling already has become a top priority and referred to the G7 meeting that took place in Biarritz, France this summer, where the heads of state and governments agreed to “take immediate actions to improve efficiency in the cooling sector while phasing down HFC refrigerants as per the Kigali Amendment to the Montreal Protocol”.
AIT – Evaluate the heat pump location with Augmented Reality
Christian Köfinger from AIT, presented a tool for Augmented Reality for Heat Pump acoustics that they had developed. The idea is that the end user shall by using the tool be able to, on beforehand, evaluate different possible locations for a heat pumps unit and the visual and acoustic consequences.
There were several presentations on the theme of low GWP refrigerants, natural as well as synthetic, and how component manufacturers of compressors and heat exchangers develop their products to be adapted to these fluids and it is clear that the F-gas regulation and the Kigali agreement for HFC phase down are high on the agenda for researchers as well as for industry!
Heat pumps in industry and district heating applications
Some of the presentations related to the use of heat pumps in industry and district heating applications, first and foremost for waste heat recovery, and it is evident that there are more and more possible solutions and good examples of applications outside the traditional building sector. Heat pumps for higher temperatures are offered on the market which widens the application area for the technology.
Using heat pumps to stabilize the grid
Two of the presentation during the last afternoon revealed possibilities and challenges related to using heat pumps to stabilize the grid when a large fraction of the electricity production originates from renewable energy sources such as wind and solar.
Tommy Walfridson from RISE talked about results from trials with controlling a heat pump with external signals to follow a required electricity load profile, which had been performed within the EU funded project Flexible Heat and Power.
Wiebeke Meesenburg from DTU talked about Flexible operation of heat pumps in district heating system to unlock synergies between the heating and power sector in Denmark, which has a very high fraction of wind power in their electricity grid. The conclusions when it comes to frequency regulation were that heat pumps can be part of the tertiary reserve. The secondary reserve is also possible with optimized control structure. However, to take part of the primary frequency regulation needs additional measures that allow for fast regulation for the heat pump. She also emphasized that the business model is important! For the district heating company that own and run the heat pump, any reduction in the electricity cost gives a better gain. This can be obtained by bidding on the electricity flexibility market. However, the bidding strategy is important!
Interesting days and meetings
To conclude the European Heat Pump Summit offered interesting days when specialists from industry and research institutions, planners, energy consultants, plant assemblers, and operators of local authority could meet and exchange knowledge and experience!
The Technology Collaboration Programme on Heat Pumping Technologies (HPT TCP) was very visible at the Summit. In the Foyer Expo HPT TCP had a booth where printed material was distributed, and visitors were informed about the programme. Several of the HPT Annexes where presented, i.e. Annex 45, Annex 49, Annex 54 and Annex 55.
