MOTOR VEHICLE WITH A CONDITIONING CIRCUIT HAVING AN HEAT EXCHANGER WITH A PHASE CHANGE MATERIAL

A motor vehicle comprises a first conditioning circuit configured to cyclically circulate a first conditioning fluid along a first path in a closed loop, the first conditioning circuit comprising on the first path, a first heat exchanger configured to expose the first conditioning fluid to a first heat exchange with a second conditioning fluid external to the first conditioning circuit, and a second heat exchanger comprising a material confined in a closed thermodynamic system, arranged to make thermal contact with the first conditioning fluid and adapted to switch between a solid phase and a liquid phase only when a temperature of the first conditioning fluid in thermal contact with the material satisfies a relationship with a phase change threshold, thus resulting in a second heat exchange between the material and the first conditioning fluid based on a latent heat of the material.
