Method for controlling a compression refrigeration system, in particular a heat pump, in which - a gaseous refrigerant is compressed from a low pressure to a high pressure by means of a compressor controlled by a controller, - the refrigerant is driven through a condenser, in which it transfers a heating energy (Q h) to a heating medium located in a heat sink system, - an internal heat (Q i) of the refrigerant is exchanged in a recuperator while the refrigerant flows under high pressure from the condenser to the expansion valve with the refrigerant flowing under low pressure from the evaporator to the compressor, - the refrigerant is guided in a high pressure flow direction (S HD) to an expansion valve controlled by the controller, in which the refrigerant is expanded from the high pressure to the low pressure in a controlled manner depending on a control value, wherein - the refrigerant at the low pressure ND evaporates in the evaporator upon absorption of source heat Q Q, including the method steps: - determining a target value (Z ÜA) of the evaporator discharge superheating (T ÜA) and a target value (Z ÜE) of the compressor intake superheating (T ÜE), - calculating a correction value based on a control deviation of the compressor intake superheating (T ÜE) from the target value (Z ÜE) of the compressor intake superheating (T ÜE), - correcting the target value (Z ÜA) of the evaporator discharge superheating (T ÜA) with the calculated correction value, - calculating a control value after a commissioning phase of the compression refrigeration system depending on the target value (Z ÜA) of the evaporator discharge superheating (T ÜA) and the target value (Z ÜE) of the compressor intake superheating (T ÜE), and - controlling the expansion valve based on the control value. - a gaseous refrigerant is compressed from a low pressure to a high pressure by means of a compressor controlled by a controller, - the refrigerant is driven through a condenser, in which it transfers a heating energy (Q h) to a heating medium located in a heat sink system, - an internal heat (Q i) of the refrigerant is exchanged in a recuperator while the refrigerant flows under high pressure from the condenser to the expansion valve with the refrigerant flowing under low pressure from the evaporator to the compressor, - the refrigerant is guided in a high pressure flow direction (S HD) to an expansion valve controlled by the controller, in which the refrigerant is expanded from the high pressure to the low pressure in a controlled manner depending on a control value, wherein - the refrigerant at the low pressure ND evaporates in the evaporator upon absorption of source heat Q Q, - determining a target value (Z ÜA) of the evaporator discharge superheating (T ÜA) and a target value (Z ÜE) of the compressor intake superheating (T ÜE), - calculating a correction value based on a control deviation of the compressor intake superheating (T ÜE) from the target value (Z ÜE) of the compressor intake superheating (T ÜE), - correcting the target value (Z ÜA) of the evaporator discharge superheating (T ÜA) with the calculated correction value, - calculating a control value after a commissioning phase of the compression refrigeration system depending on the target value (Z ÜA) of the evaporator discharge superheating (T ÜA) and the target value (Z ÜE) of the compressor intake superheating (T ÜE), and - controlling the expansion valve based on the control value.
