Abstract (en)
[origin: EP1148302A2] The heat exchanger (8), on the primary side, is incorporated in a heating circuit fitted with a circulating pump (4) with controllable rotational speed and leading over a heat source (3) especially a buffer storage. A proportional-integral-differential regulator controls the pump-drive (10) in relation to the comparison of the measured secondary-side outflow temperature of the heat exchanger as actual value with a pre-set desired value. The PID regulator (9) is fitted with a regulator stage for the rotational speed of nil, and the pump drive is controlled over the entire rotational speed range only in relation to the comparison of the actual and desired values.
