The present invention relates to a temperature control device having a pump for delivering a temperature control medium, a pressure measuring device downstream of the pump, a blocking device downstream of the pressure measuring device, and a control and evaluation unit. The temperature control device allows simple, inexpensive and rapid measuring of flow of the temperature control medium flowing in the circuit, wherein wear uncertainties of the pump or system changes are also considered. According to the invention, a pump characteristic curve of the pump of the temperature control device is stored in the control and evaluation unit, representing the relationship between a pump pressure of the temperature control device and a flow quantity of the temperature control medium, and the control and evaluation unit is designed such that the pump characteristic curve can be calibrated. The invention further relates to a method for determining the flow quantity of the temperature control medium in a temperature control device described above. |
