Abstract
Un système de réfrigération CO2 comprend un circuit de réfrigération dans lequel circule un réfrigérant CO2 entre un étage de compression dans lequel le réfrigérant CO2 est comprimé. Un étage de condensation est prévu dans lequel le réfrigérant CO2 dégage de la chaleur et est accumulé dans un réservoir de condensation. Un étage d'évaporation est prévu dans lequel le réfrigérant CO2 est détendu à l'état gazeux pour absorber la chaleur d'un fluide à refroidir, avec au moins une partie du réfrigérant CO2 sortant de l'étage d'évaporation étant dirigée vers un circuit supra-compression comprenant un étage de supra-compression dans lequel la partie de réfrigérant CO2 est comprimée. Un échangeur de chaleur est fourni par l'intermédiaire duquel le réfrigérant comprimé CO2 est dans une relation d'échange thermique avec un circuit de réfrigération secondaire, de telle sorte que le réfrigérant CO2 comprimé dégage de la chaleur à un réfrigérant secondaire utilisé pour le chauffage. Des moyens de régulation de pression commandent la pression du réfrigérant CO2 comprimé étant renvoyé à l'étage de condensation.
