Working Group - Solid-State Cooling and Heating

Objectives of the working group


The first objective of the Working Group is to promote international research collaboration in the areas of solid-state cooling, heat pumps, and energy harvesting, with the aim of providing energy-efficient and environmentally friendly solutions for a variety of applications.

The second objective is to establish technology transfer through collaboration between research institutes and various industries, and to report on the progress of developments towards real market applications.

The third objective is to comprehensively promote energy efficient solutions for solid state cooling, heating and energy harvesting that can have an important impact on efficient energy conversion, decarbonisation of various sectors and the circular economy. The Working Group is led by a Chair, a Vice-Chair, a Scientific Committee and Board of Industries to carry out the relevant activities in cooperation with the members of the Working Group and other international groups. The Working Group will focus on all existing and future domains of solid-state cooling, heating, and energy harvesting:

  • Caloric technologies for heating and cooling,
  • Caloric technologies for energy harvesting,
  • Thermoelectric technologies for heating and cooling,
  • Thermoelectric technologies for energy harvesting,
  • Spincaloritronic technologies for cooling, heating, and energy harvesting,
  • Solid-state cryocoolers and liquefaction,
  • Other solid-state technologies for heating, cooling, and energy harvesting.




Latest activities

The Working Group is currently forming the international group of the Scientific Committee and the Board of Industries. This work will be carried out until the end of 2022.


Futures activities

The first official meeting of the Chairs, Scientific Committee and Board of Industries will be held online in January, 2023, together with the organisers of the IIR THERMAG 10 international conference, to be held in August 2024 in Baotou, Inner Mongolia, China. The newly established Scientific Committee and Board of industries will evaluate the Work Programme for the period 2022-2025, and the implementation of its activities.
