Claim 3:
4. A method in accordance with claim 1, characterized in that the value D is measured in that a temperature change is carried out at the side of the heat carrier medium and the time development of the temperature of the heat carrier medium at the inlet and at the outlet is integrated over time and the value D is determined from the relationship

D=Qd(1−Ado/Adi)  (4)

where Ado represents the area, optionally corrected by a baseline, below the temperature curve over time at the outlet side of the heat exchanger and Adi represents the area, optionally corrected by a baseline, below the temperature curve over time at the inlet side of the heat exchanger.
