Refrigeration circuit device, and method for operating a refrigeration circuit device of this type

A refrigeration circuit device, comprising:

• a compressor (1) for compressing a refrigerant,
• a condenser (2) connected downstream of the compressor (1) in a flow direction of the refrigerant,
• a first expansion device (3) connected downstream of the condenser (2) in the flow direction of the refrigerant,
• a heat exchanger (4) connected downstream of the first expansion device (3) in the flow direction of the refrigerant,
• an electronic device (7) that is to be cooled connected to the heat exchanger (4),
• a second expansion device (5) connected downstream of the heat exchanger (4) in the flow direction of the refrigerant,
• an evaporator (6) connected downstream of the second expansion device (5) in the flow direction of the refrigerant,
• wherein the compressor (1) is later connected downstream of the evaporator (6),
• wherein the heat exchanger (4) is configured as an internal heat exchanger for transferring additional heat to the refrigerant, and comprises:
• a primary side (4.1) which is connected to the first expansion device (3), and
• a secondary side (4.2) which is connected on one hand to the evaporator (6) and another hand to the compressor (1).
