Using international case studies, influencing factors and potentials for flexibility options will be evaluated and suitable business models will be derived.
IEA HPT Annex 58: High-Temperature Heat Pumps
Industrial heat pumps, especially high temperature heat pumps with useful temperatures higher than 100°C, are a central element in the future energy system. In order to increase the application of high temperature heat pumps in industry, this project will provide an overview of the technological possibilities up to the procurement process of high temperature heat pumps. This should increase the understanding of the technology and its potential and reduce existing market barriers.
IEA HPT Annex 59: Heat Pumps for Drying Processes
Drying processes are highly energy-intensive and widespread in industry and commerce as well as in households in various forms. In this project, the potential for energy savings in drying processes in various applications will be investigated, which can be tapped through the use of heat pumps and made available to the relevant target groups in the form of guidelines, data, etc.
IEA HPT Annex 60: Retrofitting Heat Pump Systems in Large Non-domestic Buildings
Lack of knowledge about retrofit options with heat pumps currently hinders the widespread use of the technology in non-residential buildings. In this project, easy-to-use, accessible recommendations for techno-economically optimised planning / design of heat pump applications in hospitals, shopping centres, industrial buildings, educational institutions, and museums will be developed and communicated to relevant target groups in the form of guidelines and training courses.
IEA HPT Annex 61: Heat Pumps in Positive Energy Districts
IEA HPT Annex 61 evaluates the role of heat pumps (HP) in positive energy districts (PED). Efficiency potentials of the electric and thermal energy of districts that can be unlocked with the use of HPs are evaluated in order to reach a positive energy balance. This refers to both, upgrade of waste heat and simultaneous generation of different energy use in buildings (space heating, DHW, space cooling/dehumidification) and includes self-consumption of on-site renewable electricity generation.
IEA HPT Annex 63: Impact of heat pump placement on noise emissions
Noise emissions from heat pumps are a potential barrier for broad market diffusion of this energy efficiency technology, especially in urban areas. In this project, the influences of noise emissions in the building and in the neighbourhood are characterised, their psychoacoustic effects are analysed in more detail, and tools for digitally supporting heat pump placement are further developed. The results will be presented to relevant target groups in the form of guidelines and other documentation.
IEA HPT Annex 64: Safety measures for flammable refrigerants
New bans on chemicals and the revision of the so-called F-Gas Regulation pose new challenges for the heat pump and refrigeration industry. In this project, new knowledge regarding the safe future use of flammable refrigerants in heat pump and refrigeration systems up to 50 kW for room temperature control and hot water preparation is being developed and made available to the relevant target groups.
