Title:
REFRIGERATION MACHINE
Document Type and Number:
WIPO Patent Application WO/2022/191166
Kind Code:
A1
Abstract:
This turbo Brayton refrigeration machine (11) is characterized by comprising a first circulation path (L1) in which a first refrigerant circulates, a second circulation path (L2) in which a second refrigerant that is to be cooled circulates, a sub-cooler (22) that is disposed spanning the first circulation path (L1) and the second circulation path (L2) and that has a single heat exchange unit, and an expansion turbine (21) that is positioned on the primary side of the sub-cooler (22) in the first circulation path (L1), the turbo Brayton refrigeration machine (11) being further characterized in that the pressure ratio in the expansion turbine (21) is such that the outlet temperature of the expansion turbine (21) is higher than the condensation point of the second refrigerant.
