Abstract: A temperature control device has a flow line (15) for supplying a consumer, connected to the flow line (15), with a liquid medium at a predetermined temperature. A return line (17) is connected to the consumer for returning at least one part of the liquid medium from the consumer to a mixing device (41). In a predefinable ratio, the liquid medium of the return line (17) is mixed in the mixing device with a storage medium provided in a tank (25). The mixing device has a mixing chamber (41) arranged below the filling level of the tank (25) with the storage medium.

Abstract: The invention relates to a temperature control device having a flow line (15) for supplying a consumer, which can be connected to said flow line (15), with a liquid medium at a predetermined temperature, also comprising a return line (17) which can be connected to the consumer for returning at least one part of the liquid medium from the consumer to a mixing device (41), in which in a predefinable ratio, the liquid medium of the return line (17) is mixed with a storage medium provided in a tank (25). The invention is characterized is that said mixing device comprises at least one mixing chamber (41) which is arranged, when the temperature control device is in operation, below the filling level of the tank (25) with the storage medium.
