Abstract

The invention relates to a device for storing temperature-controlled fluids, comprising at least one container ( 20 ), a Peltier element ( 30 ), the hot side ( 301 ) of which is in contact with at least one wall ( 201 ) of the container ( 209 ), at least one device ( 40 ) for delivering ambient air to the cold side ( 302 ) of the Peltier element ( 30 ), and at least one electrical energy source ( 50, 501, 502 ) for supplying the Peltier element ( 30 ) and the device ( 40 ) for delivering the ambient air. For low-loss storage of the fluid in the container ( 20 ), the device ( 40 ) for delivering ambient air can be operated according to the temperature of the ambient air and the heating capacity of the Peltier element ( 30 ) can be controlled according to the currently produced electrical energy of a photovoltaic solar generator ( 501 ) forming an electrical energy source. Preferably, times and/or durations of the heat energy emitted from the Peltier element ( 30 ) and/or from an accumulator ( 502 ) to the fluid can be controlled by a control appliance ( 6 ) on the basis of at least one requirements specification stored in the control appliance ( 60 ).
