Correspondingly, the temperature difference for Q 80 is 80 Kelvin and for Q 60 it is 60 Kelvin.
This standardized value can be used to calculate the current output of the heat exchanger with the same mass and volume flows and different inlet temperatures - e.g. B. during a test drive with changing coolant or air inlet temperatures:
Q 100 can also be determined as a map as a function of different mass flows .
