Ideas and Proposals

HPT welcomes ideas and topics for new international collaborations!

If you have a suggestion for an international collaborative project of the IEA Heat Pumping Technologies, please contact the Heat Pump Centre. The HPT aims to increase the number of collaborative projects and your suggestions are therefore very welcome.

The strategy for the TCP for 2018-2023 includes performing RDD&D activities within the areas of heating, cooling and refrigeration for the building, community, transport and industrial sectors, while widening the scope to include the following points to a larger extent:

  • Affordable and competitive technologies for heating;
  • More efficient cooling and air-conditioning, especially in warm and humid climates;
  • Flexible, sustainable and clean system solutions (e.g. in urban areas) using combinations of heat pumping technologies with energy storage, smart grid, solar and wind energy, thermal networks, energy prosumers, etc.;
  • Possibilities offered by the developments in the area of digitalisation and Internet of Things;
  • New or special markets and applications, including automotive, industry and consumer products (e.g. white goods);
  • New, alternative or natural refrigerants with lower global warming potential, high thermodynamic potential and low toxicity for both new and existing applications

The following ideas/proposals are right now under development of becoming a new Annex in the Heat Pumping Technologies TCP. If you are interested in any of the ideas or have other ideas, please contact the person listed in the table below, your ExCo delegate or the Heat Pump Centre.

Idea/Proposal description Status
Heat pumps for multi-family residential buildings in cities

Heat pumps are already today the number one technology in new, typically single-family houses, in a number of countries. As regards multi-family buildings, there exist good examples of heat pumps implementation, however, it is not yet a widely chosen solution. At the same time, there is an ongoing trend for migration to high-density cities and, consequently, the significance of multi-family houses is on the rise. In the light of the above, there is a strong need to search for and to provide optimal solutions for heat pumps implementation in high-density cities, with the focus on new and existing multi-family buildings.

Circular economy for heat pumps – annex idea from the National Experts meetings 2021

International organizations and countries are preparing legislation to promote a circular economy, and this is expected to affect heat pumps in the coming years. The legislation related to circular economy can influence both the product design and the business models of residential heat pumps. This means that it is important for manufacturers and knowledge institutions to gain knowledge in this area. The aim of the proposed annex is to obtain and share knowledge on different aspects of circular economy such as material efficiency, take-back strategies, design guidelines and business models.
