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.

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: Industrial High-Temperature Heat Pumps

High-temperature heat pumps are key elements in the decarbonisation of industrial process heat. In this project, existing activities to promote the market ramp-up of this technology will be continued. An existing technology database of manufacturers, their close-to-market or market-available products and demonstration projects will be continued. Moreover, recommendations for sector-specific solutions and training materials will be developed and disseminated to relevant target groups.

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 HPP Annex 47: Heat Pumps in District Heating and Cooling Systems

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.

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 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.
