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 drying.

Contact: Dr. Michael Lauermann, michael.lauermann@ait.ac.at

Proposal
Heat Pumps in Positive Energy Districts.

Based on climate protection requirements more and more cities declare zero-emission targets. Thus, concepts to reach zero energy/emission are getting important. The Annex will evaluate concepts to reach a net-zero/positive energy balance cost-effectively by heat pump application. Starting from individual building concepts the extension to groups of buildings and neighbourhoods is investigated for different load structures assessing electric and thermal integration options, also for retrofit applications. By thermo-economic analysis of system integration, component design and controls as well as storage options, recommendations to improve the performance and energy flexibility of heat pumps in positive energy neighbourhoods are derived by simulation and monitoring.

Proposal
Comfort & Climate Box for warm and humid climates.

Proposal
Retrofit Heat Pump Systems in Larger Existing non-Residential Buildings.

The objective of this Annex is to simplify and strengthen the selection of appropriate types of heat pump based heating, ventilation and cooling (HVAC) systems for retrofitting to existing large non-domestic buildings. These types of buildings are very varied in form, size, and function, differ in the types of HVAC systems that are already installed, and in their access to energy supply networks. This complexity, plus the wide variety of possible heat pump retrofit options results in a rather complicated and confusing context for decision makers who own and operate the buildings, which can hinder the take up of heat pump systems. This will be addressed by developing guidance procedures and tools based on evidence from monitored case studies.

Proposal
Heat pumps in high-density 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.
