ABSTRACT:
In the airplane of the present invention, a part of the outer skin (10) is not provided with an insulating layer (11). A cold air chamber (13) is provided behind this part being in heat exchange with the ambient air via the outer skin (10). A flow-in duct leads from the cold air chamber (13) to the cooling chamber (16) and a flow-out duct (21) leads from the cooling chamber (16) back to the cold air chamber (13). The cold air chamber (13) and the cooling chamber (16) form a closed recirculation system, thereby cooling the cooling chamber (16) suited for receiving a service trolley (29). A thermostat (25) controls air quantity regulating valves (22;24) and a van (23) in order to maintain a desired temperature within the cooling chamber (16).
