Abstract

Un système frigorifique par CO2 comprenant un circuit de réfrigération où circule du réfrigérant au CO2 après un étage de compression dans lequel le réfrigérant au CO2 est comprimé. Un étage de condensation est utilisé, dans lequel le réfrigérant au CO2 dégage la chaleur et est accumulé dans un réservoir de condensation. Un étage d'évaporation est utilisé, dans lequel le réfrigérant au CO2 est dilaté en un état gazeux pour absorber de la chaleur d'un fluide pour la réfrigération, au moins une partie du réfrigérant au CO2 sortant de l'étage d'évaporation étant dirigé vers un circuit de surcompression comprenant un étage de surcompression dans lequel la partie de réfrigérant au CO2 est comprimée. Un échangeur de chaleur est utilisé, par lequel le réfrigérant au CO2 comprimé est dans une relation d'échange de chaleur avec un circuit de réfrigérant secondaire, de sorte que le réfrigérant au CO2 comprimé dégage de la chaleur vers un réfrigérant secondaire utilisé à des fins de chauffage. Des moyens de régulation de pression commandent la pression du réfrigérant au CO2 comprimé étant retourné vers l'étage de condensation.
