Procédé de pompe à chaleur souple actionnée par l'énergie mécanique environnementale récupérée et dispositif associé Le procédé produit chaleur et fraîcheur dans un matériau souple et élastique comprenant des alvéoles étanches remplies de gaz, par compression puis détente du gaz emprisonné dans ses alvéoles. Le matériau comprend 3 couches, l'une dotée d'alvéoles dites froides, l'autre dotée d'alvéoles dites chaudes et une couche intermédiaire comprenant des tuyères, assemblées de manière étanche afin que chaque alvéole froide soit en communication avec une alvéole chaude via une des tuyères. Pour l'application aux semelles de chaussure, à chaque pas, le pied compresse les alvéoles froides et tout le gaz est comprimé dans les alvéoles chaudes via les tuyères et s'échauffe naturellement. Lorsque le pied se relève, le matériau reprend son volume grâce à son élasticité détendant ainsi l'air et le refroidissant naturellement. Le cycle se poursuit tant que la personne marche ou coure. Method involving a flexible heat pump actuated by recuperated environmental energy and associated device. The method that forms the subject of the invention is a method for producing heat and cold in a flexible material comprising gas-filled fluid-tight cells by compressing and expanding the gas trapped in these cells when pressure is applied to the flexible material such as, for example, when the foot of an individual or of an animal is pressing down on the ground, or a tyre is in contact with the road. The flexible material is preferably silicone or some other elastic or hyperelastic elastomer and is made up of three layers: * a layer provided with so-called cold cells and of which the geometry or hardness allows these to be compressed before the so-called hot cells, * a layer provided with so-called hot cells and of which the geometry or hardness allows these not to be compressed while the so-called cold cell is being compressed, * an intermediate layer between the previous 2 layers and comprising nozzles of a geometry suited to proper expansion of the gas. These three layers are superposed and assembled in a fluid-tight manner so that each so-called cold cell is in communication with a so-called hot cell via one of the nozzles. The method may be employed in the soles of shoes so as to maintain a cool temperature when the individual is running on baking-hot ground or a warm temperature on freezing ground since these soles are thus reversible. With each footstep, the foot will compress the so-called cold cells and all of the gas will be compressed into the so-called hot cells via the nozzles. As it is compressed, the gas will naturally warm up in accordance with the laws of thermodynamics. When the foot leaves the ground and there is therefore no longer any compression, the flexible material will regain its volume through the elasticity of the material, and the so-called cold cells will draw the gas from the so-called hot cells and therefore expand it via the nozzles and this will naturally cool this gas in accordance with those same laws. The cycle is ongoing as long as the individual is walking or running.
