1. An aircraft passenger service device for receiving goods for cold storage that are to be supplied to aircraft passengers, the passenger service device comprising:
a receiving device which includes a viewing apparatus, a coolant inlet for feeding a coolant into the receiving device, and a coolant outlet for discharging the coolant from the receiving device, wherein the viewing apparatus is designed to enable a user to inspect goods stored in the receiving device before they are removed from the receiving device, and
a cooling arrangement which includes:
a coolant circuit line connected to the coolant inlet and the coolant outlet of the receiving device, the coolant circuit line circulating the coolant to and from the receiving device,
a device that directs into the coolant circuit line a refrigerant fluid flowing through a refrigerant fluid circuit line of a central cooling system of the aircraft, thereby mixing the refrigerant fluid and the coolant, and
a control device that controls at least one of the temperature and the temperature distribution within the receiving device,
wherein the control device includes a bypass line positioned to feed heated-up coolant discharged from the receiving device via the coolant outlet of the receiving device, into the coolant circuit line at a rejoining location downstream of the device that directs into the coolant circuit line the refrigerant fluid flowing through the refrigerant fluid circuit line and upstream of the coolant inlet of the receiving device.
