Abstract: An aircraft passenger service device for receiving goods for cold storage to be supplied to aircraft passengers includes a receiving device having 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. The viewing apparatus is designed to enable a user to inspect goods stored in the receiving device before removal. The aircraft passenger service device further includes a cooling arrangement having a coolant circuit line connected to the coolant inlet and the coolant outlet of the receiving device, and 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.

Abstract: An auxiliary cooling device is configured to be operated outside of an aircraft. The auxiliary cooling device is configured to be connected to an aircraft liquid cooling system which includes a refrigerating device, a coolant supply connection, a coolant discharge connection, and a control device. The auxiliary cooling device includes a cold source that is adapted to cool a coolant down to a desired low temperature, an auxiliary cooling device outlet which is connected to the cold source and connectable to the coolant supply connection. The auxiliary cooling device also includes an auxiliary cooling device inlet which is connected to the cold source and connectable to the coolant discharge connection of the aircraft liquid cooling system.

Abstract: The present invention discloses a service method and a service device (50) for a liquid cooling system (1) of an aircraft, the service device (50) being adapted to send at least one instruction to a liquid cooling control device (10) of the liquid cooling system (1). A plurality of service lines (52, 54, 56, 58, 62) are then connected between the service device (50) and the to liquid cooling system (1). The entire liquid cooling system (1) or a sub-system (12) can then be filled, emptied, deaerated and checked in respect of a leakage. Further, it is possible to set the fill level of a reservoir (8) and to service a fill-level sensor (99) of the reservoir (8).

Abstract: An auxiliary cooling device (100) is configured to be operated outside of an aircraft and comprises a cold source that is adapted to cool a coolant down to a desired low temperature, an auxiliary cooling device outlet (104) which is connected to the cold source and connectable to a coolant supply connection (28) of an aircraft liquid cooling system (4) in order to deliver coolant cooled to a desired low temperature by the cold source to the aircraft liquid cooling system (4), and an auxiliary cooling device inlet (102) which is connected to the cold source and connectable to a coolant discharge connection (26) of the aircraft liquid cooling system (4) in order to receive coolant heated by heat absorption from a heat load (12) in the aircraft (2).

Abstract: An aircraft passenger service device (10) for receiving goods for cold storage to be supplied to aircraft passengers comprises a receiving device (12) which comprises a viewing apparatus, a coolant inlet (14) for feeding a coolant into the receiving device (12) and a coolant outlet (18) for discharging the coolant from said receiving device (12), wherein the viewing apparatus is designed to enable a user to inspect goods stored in the receiving device (12) before they are removed from the receiving device (12). The aircraft passenger service device (10) further comprises a cooling arrangement (20) which comprises a coolant circuit line (22) connected to the coolant inlet (14) and the coolant outlet (18) of the receiving device (12), and a device (27) for thermally coupling a coolant flowing through the coolant circuit line (22) to a refrigerant fluid flowing through a refrigerant fluid circuit line (28) of a central cooling system (30) of the aircraft.
