1. An aircraft on-board kitchen module comprising:
a first compartment for drinks and/or food;
a thermoelectric element for conditioning an internal temperature of the first compartment and having a first and a second heat exchanger, one of the heat exchangers forming a cold side and the other heat exchanger forming a hot side of the thermoelectric element;
control means connected to the thermoelectric element such that heat generated by the thermoelectric element is extracted by a primary coolant from a central cooling system of the aircraft, the primary coolant being supplied via a coolant duct that is selectively supplied with ambient air from the cabin and/or conditioned cold air from the central cooling system of the aircraft; and
means for switching air circulation in the first compartment between a first operating mode with closed circulation of warm or cold air within the first compartment and a second operating mode with open circulation of cooling air through the coolant duct.
