'Time points' are awarded according to the adequacy of the solution with the type of innovations sought by Time for the Planet®. They correspond to the analysis of several factors :

  • impact potential: impact average score > 4 => 0,5 point / if > 4,15 => 1 point.
  • global consistency: all average score of the 6 selection criteria > 2,5 => 1 point.
  • the favourite: % of assessments judge the innovation as a top one to act on a global scale against greenhouse gases > 20% => 1 point
  • the targeting: validation of Time for the Planet<span class="brand">®</span> scope of action higher than 90% => 0,5 point + innovation level of maturity is enough => 0,5 point
  • social acceptability: semantic analysis score of comments > 0 => 0,5 point/ if > 3500 => 1 point

The projet in details

What is the issue addressed?

With global warming, the need for cooling is increasing. Current technologies use fluorinated refrigerants, which have a very high global warming potential, to generate cold. Known alternatives to these refrigerants are causing other environmental and safety issues and are therefore not recommended. Aware that cooling is essential to human activities, Leviathan Dynamics has developed a technology that can meet this need, for industry first and for comfort later, while limiting the impact of cooling down places on global warming.

How is the problem solved?

We use the most natural of refrigerants, water, in an innovative mechanical stream compression cycle. This enables us to offer machines that do not use refrigerants that add to global warming while reducing the energy consumption of the machines by 30 %.

What is the customer target?

In the first place, the industry sector who uses coolers all year round. We are particularly interested in the plastics, mechanical, digital and chemical industries. with this type of process, we can reduce energy consumption by 30% in nominal operation and by 50 % over a full year.

How is this solution different?

The main innovations are: 1/ the development of a very compact multi-stage high-speed centrifugal compressor technology that is suitable to vacuum water steam 2/ the use of a direct exchange thermodynamic cycle that allows an improvement of energy efficiency by around 30 %.

Scientific Committee opinion

S’affranchir des gaz fluorés en réfrigération est une prouesse. La solution proposée est solide techniquement et permet à la fois une amélioration de la performance énergétique et la suppression de l’usage de fluides frigorigènes, désastreux pour l'environnement. Le produit répond à une exigence forte au niveau de l’Union européenne avec la mise en place de quotas sur les HFC (depuis 2015) et une réduction visée de 79 % des HFC en 2030. Techniquement, le point fort de l'innovation réside dans le développement d'un compresseur de vapeur d'eau de type centrifuge à double étages pour des applications de climatisation / rafraîchissement de bâtiments. La fiabilité de ce compresseur à grande vitesse sur la durée ainsi que le positionnement face à la concurrence seront déterminants pour la réussite du projet. A la fois parce que de très gros acteurs vont très rapidement se positionner sur ce marché, et parce que d'autres procédés sans HFC existent déjà (utilisant du CO2 ou de l'ammoniac par exemple). Le modèle de licence libre imaginé par Time for the Planet offre des perspectives uniques pour un déploiement massif de cette solution utilisable dans tout type de contexte industriel.
