Abstract (en)

[origin: EP2051027A2] The system has valves (20, 21) provided in front of an evaporator (3), and valves (17, 18) provided behind the evaporator. Two paths (B, C) are provided parallel to the evaporator. The valves (17, 18, 20, 21) are designed such that a flow direction at the evaporator is unchanged independent of change of a flow direction of a refrigerant e.g. carbon hydride. The evaporator is used as a liquefier in an operation mode for liquefying the refrigerant and is used as a vaporizer in another operation mode for evaporating the refrigerant.
