Problems solved by technology
[0005] Storing food in refrigerated trolleys or refrigerated storage units arranged in the galley area has the disadvantage that the food must be distributed to the passengers by the flight attendant
As a result, the provisioning of passengers is time-consuming and intensive for the flight attendants
In addition, even when a large number of flight attendants are deployed, it is difficult to ensure that all passengers are served at the same time or even when they are needed
A further disadvantage of the equipment commonly used in aircraft for storing food to be served to aircraft passengers lies in the fact that passengers cannot see the dishes to choose from, for example when ordering food
This can lead to dishes chosen based on verbal descriptions ending up inconsistent with expectations

Embodiment Construction
[0029] figure 1 and figure 2 The aircraft passenger service unit 10 shown in FIG. 2 includes a container 12 constructed in the form of a cabinet for containing refrigerated items. These items may be, for example, food or drink, and may be used to serve aircraft passengers during the flight. as can be obtained from figure 2 As inferred from , the receiving device 12 has a plurality of compartments in which refrigerated items can be located. On the front side, i.e. the side accessible to the user of the aircraft passenger service device 10, the receptacle 12 is equipped with a viewing device designed to enable the user to remove the stored contents of the receptacle 12 from the receptacle 12. View these items before listing. The viewing device may comprise, for example, a pane of insulating glass. The compartments of the housing device 12 are individually accessible. As an alternative to this, however, it is also possible to provide only a single door for the receiving d...

The invention relates to an aircraft passenger service device (10) for receiving goods for cold storage to be supplied to aircraft passengers, comprising a receiving device (12) comprising a viewing device, a coolant inlet (14) for feeding a coolant into the receiving device (12) and a coolant outlet (18) for removing the coolant from the receiving device (12), wherein the viewing device is designed such that it allows a user to view the goods stored in the receiving device (12) prior to removal thereof from the receiving device (12). The aircraft passenger service device (10) further comprises a cooling arrangement (20) comprising a coolant circuit line (22), which is 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.
Description
technical field [0001] The present invention relates to an aircraft passenger service unit for containing refrigerated items such as food and drink to be served to aircraft passengers. Background technique [0002] In modern airliners, meals and drinks intended to be served to the aircraft passengers during the flight are usually stored in trolleys or suitably arranged cabinets in the galley area until they are distributed to the aircraft passengers by the flight attendants. In order to keep the meals and drinks cool until they are consumed, it is known to cool trolleys or storage cabinets provided in the kitchen area by means of dry ice. For this purpose, dry ice frost in the form of compacted blocks is introduced into the upper compartment of the trolley or storage cabinet to be cooled, so that the carbon dioxide gas stored in the trolley or storage cabinet is cooled by means of carbon dioxide gas produced by sublimation and forced to sink by gravity. Items are cooled. C...
