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 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: Digital Services for Heat Pumps

Digital services such as advanced modelling, big data methods and augmented reality are not yet widespread in the heat pump industry, although they can be essential for market penetration and decarbonisation. In the project it will be analysed how such services can be used over the life cycle, especially for product design/testing, integration, and operation/maintenance. Expertise from R&D and practice will be collected in an international database and disseminated in the industry.

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 Task 41: Cold Climate Heat Pumps

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.
