Abstract:
1. A procedure for controlling the temperature of at least one outbound secondary flow ( 2 u ) in a secondary circuit from a heat exchanger ( 1 ) by means of a primary flow ( 3 ) in a primary circuit, where a control unit ( 7 ) controls a regulatory member ( 5 , 11 ) that regulates the primary flow, wherein the temperature T sec in of the inbound secondary flow ( 2 i ) in the secondary circuit is known or measured, characterised in that, a) a parameter array, characteristic of the enthalpy difference (Δh) between the inbound primary flow ( b) a parameter array, characteristic of the mass flow (m c) a parameter array, characteristic of the mass flow (m d) and that the parameters determined in points a) through c) are transmitted to the control unit ( 1) the power needed to change the temperature of the secondary medium from the current inbound temperature T 2) assumed power demand for compensation of stored energy in the heat exchanger ( 3) assumed leak power from the heat exchanger.
