PAC-TA | ARKTEA Research Project

Heat Pump - Thermo Acoustic


Group : Dependability and Decision Support

Labelling: none

Duration: 2 years (2021 - 2023)

Funding: Pays de la Loire Region

Staff involved from LARIS: Thierry LEMENAND, Abderafi CHARKI, Nizar CHATTI (teacher-researchers), Rima AL ARIDI, Bassel CHOKR (PhD students)

Project partners:: ARKTEOS (Vincent Gatto), EQUIUM (Olivier Saquet), ADNE INGENIERIE (Driss Sakami)



This project aims to develop a thermo-acoustic heat pump that does not use any refrigerants. This objective is clearly a response to the F-Gas directive (regulation 517/2014/EU) which aims to reduce the use of fluorinated gases with a high Global Warming Potential (GWP) in order to divide CO2 equivalent emissions by five by 2030.

There are currently no such devices on the market and the industrial partners involved are aiming for a first marketable model at the end of this two-year project.

At LARIS, the researchers will be involved in the instrumentation of a first functional prototype of a thermo-acoustic core heat pump. First, a test bench will be designed and built specifically to test the TA modules in this project. We will then carry out experimental measurements and exploit the data to enable an analysis of the performance and operation of this innovative system, and compare it with the performance of a "conventional" thermodynamic compression heat pump.


Project objective: "Market launch of a thermo-acoustic heating system"

Two phases are planned:

  • Production of two functional prototypes of 1 kWe.
  • Production and installation of a pre-series of ten 3 kWe thermo-acoustic heat pumps

This €1M project is supported by the Pays-de-la-Loire Region via the "Call for Collaborative R&D Projects" scheme. Within this framework, LARIS is receiving 148 k€ in funding.
