A significant use of alternative heat sources with the help of district heating and cooling networks is a major challenge for a sustainable energy supply. In times of increasing shares of fluctuating producers such as PV and wind energy, the relevance of heat pumps increases. Within the framework of the IEA HPT Annex 47, potentials and barriers for the integration of heat pumps in DHC networks were analyzed.
The project aims at showing the potential of heat pumps for the energy supply of multi-family houses and providing a contribution to the elimination of market barriers. Concepts and innovative technological options of heat pumps will be analyzed making use of simulation and experiments. The results will be disseminated in international expert meetings and amongst national stakeholders.
The project aimed at investigating the performance and market potential of gas-fired absorption heat pumps (AHPs) in domestic and small commercial or industrial buildings or applications. Selected processes were simulated for various types of buildings in order to calculate the energetic, ecological and economical potential of this technology. The results were compared with monitoring data of a gas-fired AHP system. In addition, a market survey including market barriers for gas-fired AHPs in Austria was conducted and a list of market supporting measures was compiled.
A dominating concept to reach a nearly Zero Energy Building (nZEB) is the combination of solar PV systems and heat pumps. The extended scope of the Annex 49 regards the balance of single buildings and groups of buildings/neighbourhoods, a thorough investigation of heat pump integration options for nZEBs and nZE neighbourhoods by means of monitoring and simulation as well as the design and control optimization for heat pumps in nZEB and the integration into energy systems.
The project aims at enhancing the acceptance of heat pumps and removing market barriers by reducing acoustic noise emissions and vibrations. The project involves: innovative experimental laboratory work, various numerical approaches and preliminary work in context of uniform legal and normative boundary conditions. In addition, new assessment schemes are developed and perceptual tests are carried out.
The aim of the project is to record the current situation in the field of refrigerants with low Global Warming Potential (GWP). Within the framework of the Annex, the situation in Austria and Europe will be harmonised at international level. The focus of the national project is to survey the current situation in the field of the refrigerants used and to prepare an outlook until 2030 on the availability of components and systems for the use of new "low-GWP" refrigerants.
IEA HPT Annex 55: Comfort and Climate Box – Speeding up market development for integrating heat pumps and storage packages
In the IEA HPT Annex 55, heat pumps with integrated thermal/electrical storage systems for existing buildings that are as close to the market as possible will be developed. Furthermore, measures to accelerate market development will be worked out.
As digitalization progresses, heat pumps are becoming part of the Internet of Things (IoT). In this project, the opportunities and challenges of IoT-capable heat pumps for the use in households, commercial enterprises and industrial applications will be investigated and made available to the relevant target groups in the form of guidelines, data and information relevant to standards.
The aim was to increase the efficiency of outdoor air heat pumps in cold climates in locations with low outside temperatures of up to -25°C. Newly developed heat exchanger concepts were tested and optimized regarding their icing behaviour. Different circuit modifications were modelled and simulation studies for low ambient temperatures were carried out.
The aim of Annex 42 is to analyse the technical possibilities as well as the economic/regulatory framework conditions of heat pumps for load balancing in smart grids, which are largely controlled by electricity supplier, and to investigate the impact on thermal consumers and possible potentials, in order to work out economic incentive models for load shifting and the benefits for energy supply companies and end customers on this basis.
The Hydrogen TCP aims to accelerate deployment and use of hydrogen technologies by carrying out and co-ordinating collaborative activities of analysis, applied research and communication.
In IEA Hydrogen Task 41, the TIMES Austria model of the Austrian Energy Agency and the experiences from the showcase energy region WIVA P&G will be brought into the international cooperation of modellers.
Within the framework of the IEA IETS Annex 15 - Phase 3, potentials for the use of waste heat as well as technologies for its integration are collected, bundled and processed through contributions from national research activities. The aim of the project is to identify potential collaborations in an international context and to network knowledge from the individual national research activities. Newly gained knowledge is disseminated nationally, e.g. in the course of a stakeholder workshop, and integrated into ongoing research activities.
IEA IETS Annex 17: Membrane filtration for energy-efficient separation of lignocellulosic biomass components
The overarching goal of IEA IETS TCP Annex 17 is to strengthen the network of the Austrian membrane and biorefinery landscape.
The Industrial Energy-Related Technology Programme (IETS) focuses on energy use in a broad range of industry sectors. It fosters international co-operation amongst relevant research strands, networking within and across industrial sectors, as well as exchange of information and knowledge between experts from industry, science and politics.
IEA International Smart Grid Action Network (ISGAN) Annex 6 on Power T&D Systems. Working period 2015 - 2016.
The International Smart Grid Action Network (ISGAN) aims in enhancing the knowledge about Smart Grid Technologies and accelerating the development and the international deployment. The main objective of the Austrian contribution in IEA ISGAN Annex 6 is to build up knowledge and long term concepts for the development of an intelligent and integrated electricity system, with the focus on the interaction of distribution and transmission networks, including the lead of the related subtask within the Annex.
Together with experts from 11 countries, the EI-JKU has analysed cost-benefit models and developed proposals for their adaptation and further development. In the course of the work, the EI-JKU dealt in particular with two questions: how such an evaluation model can be adapted to Austrian conditions and which socio-economic factors influence the question of whether an end consumer emerges as a winner or loser from Smart Grid-based functionalities.
IEA ISGAN Annex 5: Smart Grids International Research Facility Network (SIRFN). (Working period 2013-2018)
The Smart Grids International Research Facility Network (SIRFN) aims at improving the implementation of Smart Grids technologies by collaboration between smart grid testing facilities, test beds, and large-scale demonstrations. By active participation, Austria’s position and leading role on the forefront of international Smart Grids development has been strengthened.
IEA ISGAN Annex 5: Smart Grids International Research Facility Network (SIRFN). (Working period 2019-2020)
The Smart Grids International Research Facility Network (SIRFN) aims at creating and sharing a comprehensive knowledge-base of smart grid testing facilities, test beds and important demonstration projects. Furthermore the project seeks to improve current smart grid testing and evaluation capabilities and to establish a framework for stakeholders to gain from sharing nonproprietary results, advice and assistance.
