ABSTRACT:
The compression refrigeration unit includes a compressor, a gas refrigeration unit, an expansion apparatus, and an evaporator, which are connected to one another in a circulation system, which contains a coolant, characterized in that the degree of filling of the coolant is between 50% and 100% of the critical density of the coolant. Preferably the coolant is carbon dioxide and the degree of filling of the carbon dioxide coolant is between 0.25 and 0.45 kg/L. Also provided, in another embodiment, is an intermediate heat exchanger with a first heat exchanger branch and a second heat exchanger branch, connected to the first heat exchanger branch by a thermic coupling, wherein the first heat exchanger branch is connected to the gas refrigeration unit and the expansion apparatus and the second heat exchanger branch are connected to the evaporator and the compressor.
