Abstract
The invention relates to a device (1, 10) for the production of cooled coffee, comprising a brewing unit (4) for the production of coffee, a cooling assembly (11) and a coffee cooler (14) formed as a heat exchanger, wherein the coffee cooler (14) has at least one first and one second flow path that are connected thermally but not in a fluid-conducting manner, wherein a coolant can flow through the first flow path and the second flow path is connected in a fluid-conducting manner with a coffee outlet (5) of the brewing unit (4). It is essential that the device furthermore has a fresh-water supply (2) and a fresh-water cooler (13) formed as an additional heat exchanger, wherein the fresh-water cooler (13) has at least one first and one second flow path that are connected thermally but not in a fluid conducting manner and the fresh-water supply (2) is connected in a fluid-conducting manner downstream with the second flow path of the fresh-water cooler (13), further downstream with the first flow path of the coffee cooler (14), and further downstream with the brewing unit (4) and the first flow path of the fresh-water cooler (13) is connected in a fluid-conducting manner with a coolant…
