Title
(EN) REFRIGERANT VAPOR COMPRESSION SYSTEM AND METHOD OF TRANSCRITICAL OPERATION
(FR) SYSTÈME DE COMPRESSION DE VAPEUR DE RÉFRIGÉRANT ET PROCÉDÉ D'OPÉRATION TRANSCRITIQUE
Abstract
(EN) A refrigerant vapor compression system includes a flash tank economizer defining a separation chamber is disposed in the refrigerant circuit intermediate a refrigerant heat rejection heat exchanger and a refrigerant heat absorption heat exchanger. A primary expansion valve is interdisposed in the refrigerant circuit in operative association with and upstream of the refrigerant heat absorption heat exchanger and a secondary expansion valve is interdisposed in the refrigerant circuit in operative association and upstream of the flash tank economizer. A refrigerant vapor injection line establishes refrigerant flow communication between an upper portion of the separation chamber and an intermediate pressure stage of the system's compression device and a suction pressure portion of the refrigerant circuit. A refrigerant liquid injection line establishes refrigerant flow communication between a lower portion of said separation chamber and an intermediate pressure stage of the compression device and a suction pressure portion of the refrigerant circuit.
(FR) Le système de compression de vapeur de réfrigérant selon l'invention comprend un économiseur à ballon de détente définissant une chambre de séparation est disposé dans le circuit de réfrigérant situé entre un échangeur thermique à rejet de chaleur de réfrigérant et un échangeur thermique à absorption de chaleur de réfrigérant. Un détendeur primaire est disposé dans le circuit de réfrigérant en association avec et en amont de l'échangeur thermique à absorption de chaleur de réfrigérant et un détendeur secondaire est disposé dans le circuit de réfrigérant en association avec et en amont de l'économiseur à ballon de détente. Une conduite d'injection de vapeur de réfrigérant établit une communication de flux de réfrigérant entre une partie supérieure de la chambre de séparation et d'un étage de pression intermédiaire du dispositif de compression du système et une partie de pression d'aspiration du circuit de réfrigérant. Une conduite d'injection de liquide réfrigérant établit une communication de flux de réfrigérant entre une partie inférieure de ladite chambre de séparation et d'un étage de pression intermédiaire du dispositif de compression et une partie de pression d'aspiration du circuit de réfrigérant.
